TITLE: A Method for the Objective Measurement of the Angle of
Rotation of the Polarization Plane of Light Waves
PM10DICAL: Priborostroyeniye, 1959, Nr 11i PP 10-14 (USSR)
ABSTRACT; The 'asual method of determining the polarization plane of
polarized light waves in a polarimeter is known to be employed
by rotating the ana4zer by 900 relative to the polarization
plane. This position is visually determined by adjusting the
analyzer to complete darkness. In the case of the method
described hereq the polarizer performs a rotary oscillation
round the optical axis with the cyclic frequency w . As long
as the analyzer is not in the position which causes complete
darkness in the case of the usual method being employed, an
oscillation of the light current with the cyclic frequency ci
may be observed in the Lnalyzer. If9 however, the analyzer is
in this position@ an oscillation of the light current with
the cyclic frequency of 2co occurs. Modulation of the light
current may be attained mechanically or by means of the
Card 1/3 piezoelectric effect or the Faraday effect. For the latter

method a system is described, and in table 1 the Verdet
constants of quartz and flint (-glase) are given for some
wavelengthB. The fact that the direction of rotation of the
polarization plane is independent of the direction of
light propagation in quartz is here advantageously utilized.
A comparison of the usual method with that described here shows
that at small 6 (S - unbalance angle of the optical system)-
the latter method is more accurate. In the second part
practical applications of the method described are dealt with,
and it is found to be suited for the construction of automatic
recording polarimeters, automatic saccharimeters, as well as
for automatic regulation of the concentration of optically
active substances. As an example, a spectropolarimeter (Fig 7)
is described. It consists of a quartz monochromator, a
polarizer, a container for the liquid to be investigated,
a modulator@ an analyzer, and a photoelectric cell. The
electronically amplified photoelectric feeds one of the cUls
of a reversing engine, whereas the second coil of the reversing
engine is fed by the same current source as the modulator. The

ABSTRACT: The instrument is intended for measuring and recording the
dispersion of rotation of optically active substances in a Wide range of visible and
ultraviolet radiation. It is based on an automatic polarization servo system with
the light modulation depending on the plane of polarization; the system permits
the precision measurement of the angle of rotation of the vibration plane. The
principal parts of the polarimater are shown in Enclosure 1. Experience with the;
instrument has shown that: (1) The dispersion of rotation can be measured in the

TITLE: An Automatic Polarization Colorimete
PERIODICAL: Priborostroyeniye, 1959, Nr 12, pp 12- (USSR)
ABSTRACT: The first part of thia paper deals with the physical fundamen-
tals of light polarization in crystals and with the rotation
of the polarization plane on the passage of polarized light
through optically active media, The second part describes an
automatic polarization colorimeter with which a paper publish-
ed in Priborostroyeniye, 1959, Nr 11 has already dealt. In
this instrument the polarization plane of a linearly polarized
beam is set into a sinusoidal rotary oscillation of 50 cycles
by a magneto-optical modulator. With proper position of the
analyzer, an alternating voltage of 100 cycles is induced in
the circuit of a photocelll/A particular angular position
of the analyzer with which a voltage of 100 cycles is induced
in the photocell circuit, corresponds to each ratio of the
monochromatic components of light. A glass vessel is contained
in the path of rays of the instrument, through which the liquid
to be measured flows.. Because of the absorptive power of this
solution it is necessary to readjust the position of the

circuit if the oomposition of the solution changes. The analyzer
is readjusted with the help of a reversible two--phase motor.
In the last part the author describes an automatiG recording
colorimeter based on the afore,.inentioned colorimeter. Contrary
to orthodox designing, the polarlzer of this instrument is
automatically adjusted, The positionsof the stylus and of the
polarizer are simultaneously controlled on a diagram, and thus,
the state of the passing liquid is recorded-, The instrument is
illustrated In figure 4. A circuit diagram is given in figure 5@
It was developed by the rofinery imeni Mantulin for the deter--
mination of sugar in condensates. There are 5 figures and 3

made the control of the racomic amino division difficult. The now method
makes it possible by moans of a series of filtrations and temperature regulation
to control the division of racomatos into optically active isomers despite
the continuously developing solid phase. The solid phase is separated from
,tho mothor solution by filtration In a vacuum and the return of the filtrate
for rofiltration.. Crystallization of the obtained filtrate is prevented by
heating the filtrate to a temperature of 700 or higher, a temperature 70
higher than crystallization temperature. Tho automatic control of the
division is accomplished by moans of an automatio polarimetor of a measuring
vessel into which the mother solution filtrate is drawn.under the effect of

TEXT: The author discusses peculiarities of the lunar seas testifying on
their formation prior to the epoch of maximum melting of lunar interior, during
the maximum and after It. So. for instance the Mare Crisium and Mare Humorum were
formed from impacts of bodies having fallen on the Moon even prior to the epoch
of maximum lava eruptions to the surface. Mare Imbrium was formed soon after the
maximum melting. Maria like Mare Nubium are not of impact origin but flooded
ones. Large bodies which fell on the lunar surface and formed sea depressions
constituted, in the author's opinion, once a ring of small satellites around the
Earth, which the Moon crossed receding from the latter due to tidal interaction.
The subsequent phase in development of the lunar surface was characterized by

TEXT: To study the snow cover and atmospheric precipitatio
snow-measuring traverses were undertaken in 1958 in the River Kish-
chay basin, situated on the southern slope of the Main Caucasian
Ridge. Six precipitation meters were also established, and the
amounts of deposits falling in the lower part of the basin were det-
ermined at rainfall-measuring points between Nukha and Station D. am-
archik. From these investigations it appears that the change from
increasing precipitati?n with altitude of the locality to decreasing
-precipitation occurs, in this region, at a height of 2500 - 2600 M.

Particulars of the distribution D263/D307
The zone of maximum precipitation during all seasons and taken
annually is between altitudes of 2500 and 2600 m. The most intense
increase in the precipitation occurs mainly in the summer and autumnj
(mean gradient of the increase of precipitation with height reaches
3 - 4 mm per 100 m). In winter and spring the gradients are Less
pronounced, being I - 2 mm per 100 m. Above 2600 m, the gradients
of decreasing precipitation are 3 - 5 mm per 100 m during the summer
and autumn months. The mean annual gradient of increasing precipi-
tation was 15 - 18 mm for 1959-1960, while for individual mountain
zones this value varied from 0 to 40 mm per 100 m. At heights be-
tween 2800 and 3000 m, above the height at which the increase-to-
decrease change occurred, the decrease of precipitation was 5 m forl,.
every 100 m of altitude. (Author's summa,3)*

ABSTRAM The article deals with a gyrostat provided with gas-filled baloons, suit-

lying in the principal inertial planes relative to the center, whose ends are per-
pendicular to their radius vectors, the inertia tensor of the gyrostat remains
similar to the initial tensor, and the center of inertia of the compound body re-
mains the same as before. The problem is to minimize the energy lost during the
flight of the gyrostat as the latter maneuvers. The solution is obtained in two
parts by Pontryagin's method. In the first part) dealing 'with the positioning of
the gyrostat at the prescribed point during the maneuver) reduces the problem of
existence of solutions for certain integral equations. The second problem, that of

TITLE: `Tl@and Sequence of Crystallization in Ingots of Killed

ABSTRACT: Radioactive Fe59 (introduced in the form of Fe oxide) was
employed in conjunction with the method of overturning of molds
in order to investigate crystallization processes in ingots of
steel ShKhl5SG (2.65 t) and of steels 10 and 45 (6.2-t ingots).
The radioactivity of various zones of the ingot %vas determined
from the radiation intensity of 3.5-g specimens of metal drilled
out on different levels of a longitudinal templet of the ingot. As
the crystallization progresses, the two-phase region on the
sides of the ingot amounts to 30-50 mm. After the formation
of a zone of columnar crystals, a two-phase region fed with

of the ingot. In a 6.2-ton ingot, the height of this zone extends to 850 mm.
Up to a certain time (approximately 80 min in the case of the 6.Z-t ingot) the
thickness of the crystallized layer (including, the two-phase region) taken in
a horizontal section of the ingot is proportional to the square root of the
crystallization time. Deviations from this relationship, which occ ur toward
the end of the crystallization period, are attributable to a more rapid form-
ation of a two-phase re,lion at the center of the ingot. Extension risers,
employed in production of high-quality steel ingots, may be removed only
after the crystallization of the inglot has been completed. Bibliography: 19

ABSTRACT: Radioactive tracers were used to investigate the crystalliz-
ation of Z.65-t ingots of ShKhl5SG and 6.2-t ingots of Nrs-10
and 45 steels, bottom poured. 3-5 batches of Fe59 (4.5-14.5
millicuries per t steel) were introduced as FeZ03 mixed with
Al powder. The tops of the ingots were held in the liquid state
by periodic additions of lunke rite pipe eliminator. At the same
time, crystallization of Nr-10 steel was also studied by over-
turning three ingots on single stool at different tirne intervals
after pouring. The isotope was introduced at the moments when

into a fourth on the same stool. The thickness of the frozen layer as deter-
mined by radiography was greater than when determined by pouring out the
liquid residue of the metal. This is explained by the fact that the zones of
isotope distribution describe the region of the ingot occupied by liquid metal,
whereas the thickness of the crystallized layer determined by pouring out de-
fines the region of solid metal phase alone. The difference between them is
the magnitude of the region in which two phases exist. The length of that
region along the sides of the ingot in the course of crystallization does not
exceed 30-40 mm. At the conclusion of the formation of the zone of columnar
crystals in the bottom of the 6.2-t ingot there arises a two-phase region at-
taining 850 mm in height. This region comes into being as the result of the
accumulation of equiaxed crystals that have torn away after formation on the
interface between the solid and liquid phases. The crystallization of the two-
phase region is intermittent in nature. The development of V-segregation
and axial porosity are dependent upon the taper of the ingot and the condi-
tions under which the two-phase zone is fed liquid metal from the upper por-
tion of the ingot. In the making of high-quality steel, the hot top should be
removed only after the body of the ingot has completely hardened. Within
given time limits, the thickness of the crystallized layer is proportional to
the square root of the crystallization time; the proportionality factor therein,

TITLE: The Quality of Steel from Pig Iron Produced with a Constant
Moisture Blast (Kachestvo stali iz chuguna, vyplavlennogo
ne. dutlye postoyannoy vlazhnosti)
PERIODICAL: Stall, 1958, No.1, pp. 24 - 27 (USSR).
ABSTRACT: The influence of moisture content of blist on the hydrogen
content in pig iron and the influence of hydrogen content of
pig iron on the hydrogen content of steel as well as flake
sensitivity of steel on the hydrogen content in the liquid metal
were investigated. nos. 1 and 3 blast furnaces oa the above
works were trans;erred to operation with a consta__@t moisture
blast (15-20 g/m-/). This resulted igthe smoother operation,
highgr blast temperatures ?50 - 800 C (against previous 450 -
500 0), increase in output (No,1 - 3%; NO-3 1.3%) and a
decrease in the coke rate (No.1 - 6.5%; No-3 1.3%). As the
works produce quality steel it was considered necessary to check
the possible effect of hiSher moisture in blast on the steel
quality. It was found that with increasing moisture content in
blast, the hydrogen content of pig iron increases but not
Uardl/P proportionally. However, the mean content of hydrogen in the

practically independent of the.hYdrogen content of pig or
moisture content in the blast (Fig.1), The final hydrogen
content of steel on teeming was

various levels Of moisture in blast - Tables 3 and 4, respec-
tively. It is concluded that the hydrogen content Of Pig iron
has no influence on the hydrogen content of quality steel after
melting and on teeming. The direct relationship between the
4lake sensitivity and hydrogen content of liquid metal was
not established. The methods of heating and cooling flake-
sensitive steels used on the works secure the absence of
flakes in finished products at any level of moisture in the
blast. The macro-structure of rolled semis is independent from
the moisture Content of the blasto There are 4 tables, 2

An Jmprovement in the qualit-7 of steel for axles.
An investigation indicated that defects on rolled semis for
the manufacture of axles were caused by defects in ingots
which in turn were due to unsatisfactory internal surface
of the ingot moulds. By maintaining an established practise

2.5% bottom crop improved the quality of the metal. "Bright
points" were easily noticed in tensile specimens of the
metal. It was established 'that "bright points" are not
Tetal defects but appear in tensile specimens during test-
in.- due to non-unifor-iAty stresses in the metal caused by
0
?'points" non-uniformity. The latter appears in ingots in
the form of vihisker5 and is formed due to liquation and gas
evolution during the crystallisation process. Thermal
treatment at GSOOC for 120 hours decreases the development
of"bright points"in specimens and thus also "points" non-
uniformity in semis. The results of corresponding investi-
gation carried out by TsNIIChM confirmed the above findings.

the content of oxide inclusions is higher than on ordinary
introduction of aluminium; 2) the content of aluminium oxide
in the oxide inclusions with the experimental and usual
methods of introducing aluminium in an amount of 700 9/t is
the same (about 86%)i on introduction of 300 g/t of alumin-

The use of siliconchromiwn during smeltin@'; chromium steels
in open hearth furnaces
Du:rinm studies of the possibility of a complete or partial
replacement of ferrochromium (types 1 aild 0) with silico-
chromium. (type 18) when smelting low-carbon chromium steels,
the latter have been introduced into the bath in the heated
to red heat state in the proportion of 15-20 kg/ton of steel.
The final adjustment of chromitra content was done 10-15 min-
utes later with ferrochromium. The heat was kept for a further
20-40 minutes depending on the content of chromium. In all
heats on the addition of silicochromium boiling of the bath
ceased. The following advantages of the methoa were observed:
Card 4/6
so VA33/58-9-8/29
At the Chelyabinsk Metallurgical Works
a) the period of preliminary deoxidation coincides with
the alloying process which leads to an economy in ferro-
alloys (exclusion of blast furnace ferrosilicon) and shorten-
ing of the heat by 10 minutes; b) chromium losses (due to
oxidation) from silicochromium are 5-6% lower than from
ferrochromium. The quality of metal remains the same as an
alloying vrith ferrochromium. For smelting steel containing
not more than 0.17% of carbon, the carbon content of silico-
chromium should not exceed 2%.
On i-nvestigating theffobilem of increa-sing- the yield of good
metal from 6.2, 4.51 2.65 and 1.18.,ton in-ots the following
methods were tested; a) Addition to the top of the in-ot of
an exothermic mixture containing 70% of ferrosilicon @75%0),
10/56 of silicocalc@um and 20116 of sodium nitrate; b)The use of
frothed chamotte (s.er. 0.4-0.8 G/cm3) and coal briquettes
for lining of tops (coal briquettes contained 50% of coke
breeze, 2716 of charcoal waste, 20% of sawdust and 5% of
sodium nitrate); c) Increasing the conicity of the top from
18 to 35P/o. Tho use of tops from frothed chamotte decreased
the crop top to 12%, however,their durability was very low.
Card 5/6
50V/133/58-9-8/29
At the Chelyabinsk Metallurgical Works
The lining from coal briquettes also decreased the CrOD tOP
to 12-13%, but due to difficulties in making briquettes and
the lining the method cannot be recommended for mass produc-
tion. Tops of 35% conicity did not give any improvement.

ABSTRACT: The development of the smelting practice of transformer

ABSTRACT: 1. Smelting of ferrosilicon and foundry iron with
oxygen @snriched blast. Oxygen enriched blast (up to
25.1%) is being u.,@ed on a furnace of 930 m3 working
capacity, producing mainly ferrosilicon. When the
furnace operated on normal blast a systematic
formation ef ring-shaped scaffolds was observed. W:Lth
oxygen enriched blast the output of the furnace
increased and the coke rate decreased (at 25.1% 02 by
16.7% and 2-3% respectively). The temperature in the
hearth at a distance of 750 mm from the tuyere nozzle
reaches a maximum of 1980 - 20800C. The content Of C02
reaches the highest value (12%) at the point of maximum
temperature and decreases to zero at a distance of
1250 mm from the tuyere nozzle. The content of CO in
the flame 0..5% increasing to the centre of the hearth

withdrawn through a tuyere indicated that: a) silicon
is reduced mainly above the tuyere level from liquid
slag; b) the degree of reduction of silicon in the
bosh and in the upper part of the hearth is determined
by the temperature and concentration of silica in the
primary slag; c) a partial oxidation of silicon takes
place on the tuyere level: from 10 - 13% in the centre
to 6 - 9% in the oxidation zone. Smelting of foundry
iron with oxygen enriched blast (23.5 - 24%) and
addition of steam 40 - 47 g/m3 increased the furnace
output by 9%. Smelting of foundry iron with oxygen
enriched blast was found to be uneconomical.
2. A study of the wear of the blast furnace hearth
bottom. After a furnace campaign of 14 years 4 months,
temperature measurements in the foundation, at two
levels and the temperature of iron in the bear were
carried out prior to blowing out for relining (no
details). Iron from the bear, which was in direct
contact with the chromemagnesite layer, contained less

produced. It is thought that the layer of this low
carbon iron at a temperature in the region of 1130 -
11500 (solidification temperature) acted as a protective
layer. The depth of bottom wear after 14 years was the
same as that of another furnace without a
chromemagnesite layer after a campaign of five years.

ABSTRACT: 1) The use of oxygen for smelting steel in open hearth
furnaces. Oxygen enrichment of air to 25Y* by supplying
oxygen to the flame increased the output of the
furnaces as follows:

increase in output, % 14.o 15.7 19.0
On operation with oxygen the cost of the steel
decreased bY 3.67 - 4.27 roubles/ton on the large
furnace and remained unchanged on 100 ton furnaces.
2) Pretreatment of pig iron before charging into
open hearth furnaces. Two methods of pretreatment of
pig iron in ladles were triedi blowing with oxygen
and additions of 2-4% of ore to the ladle before it
was filled with iron. In the first case the process
of desiliconisation was found to be too cumbersome:
Card 1/5 in the second case the process of desiliconisation was
SOV/133-59-6-15/4i
At the Chelyabinsk Metallurgical Works
accompanied with a considerable temperature drop
e.g. after standing of 3 hours the content of silicon
dropped from 0.83 to 0.49% and the iron temperature
from 1450 to 13200C. No comments as to the
applicability of the latter method are given.
3) A decrease in the consumption of ferromanganese.
On changing the deoxidation practice for killed and
rimming steel, i.e. adding ferromanganese into the
ladle instead of into the furnace (10-20 minutes before
tapping) a considerable saving of manganese without
deterioration in the steel quality was obtained.
4) Alloying of steel with titanium-containing scrap.
For the replacement of ferrotitanium for alloying
steels 30T, 18".GT - 40KhGT smelted in 100 ton furnacesz
titanium filings and scrap containin � 99%' of titanium
was used. After ignition to 350-400 C for the removal
of oil, the scrap was placed on the bottom of the
ladle to which steel was tapped. Titanium losses in
Card 2/5 oxidation amounted to 57.5 to 63.5%.

5) The use of graphite as a substitute for coating
materials for ingot moulds. Additions of graphite
(800 g/t) to ingot moulds during bottom pouring of
metal were tried. No changes in the surface quality
and macrostructure of carbon steels were observed but
the surface of rolled products from chromium and
silicon steels deteriorated. No carburisation of
metal during teeming was observed.
6) The use of unfired magnesite teeming nozzles
(in co-operation with the Works "Magnezit").
500 Heats of killed and rimmed steels were experimentally
teemed using unfired magnesite nozzles in 100 and
185 ton ladles with satisfactory results.
7) An improvement in the operation of regenerators.
In order to widen the regenerators and slag pockets,
the thickness of the insulation of the walls was
reduced from 230 to 115 mm, which increased the
durability of the cheeker work by 6.2%. In order to
decrease heat losses through the lining of the bottom
part of the furnace structure it is advantageous to

SOV/133-59-6-15/41
8) Cleaning of the regenerators from flue dust.
Washing of regenerators with water at a pressure of
5 - 7 atm was found to be successful but the mechanical
strength of the forsterite bricks decreased and the
temperature of the checker work decreased by 80-900C
and is recovered only after- 2-3 heats. It is planned
to increase the pressure of the cleaning water to
10-12 atm and to m4-x it with compressed air.
9) The use of unfired magnesite-chromite bricks in
open hearth roofs. Unfired magnesite-chromite roofs in
100 and 185 ton furnaces were tried. The number of
furnace repairs increased from 1.74 to 2.66 per year.
Despite the lower cost of unfired bricks, their use in
roofs of a length higher than 6 m is not advantageous.
10) Automation of the operation of the intermediate
draught valve. Reverses on 185 and 370 ton open hearth
furnaces are carried out according to "meeting gas"

PERIODICAL: Stall, 19591 Nr 9$ pp 808-811 (USSR)
ABSTRACT: Changes in the technology of smelting 38KhMYuA steel
since the start of its production in 1952, are outlined.
The main points in the smelting technology used at
present: a) a preliminary deoxidation of the bath with
pig iron after the end of the oxidising period; at the
beginning of refining,the bath is deoxidised with a
mixture of silicomanganese and 75% ferrosilicon in
lumps; b) addition of ferrochromium at the beginning of
refining; c) diffusion deoxidation with coke and
ferrosilicon during 20 minutes; d) shortening of the
reducing period to 80 minutes (instead of 120 to 150
minutes in the previous technology) metal temperature
before casting 1600 to 16200C in the ladle 1575 to 15900C.
Despite improvements in the smelting technology, the
proportion of defective metal is still high (in 1957 145S).
Card 1/3 Due to the appearance of spot segregation, head crops were

The Production of Steel 38Kh]6fYuA for Internal Combustion Engines
increased to 25%. Most common defects encountered in
this type of steel are describedt. 1) Spot segregation
consisting of localised enrichment of metal in carbon,
sulphur and phosphorus; the appearance of the defect is
associated with the evolution of gas during crystallization.
2) "Bubblesff - in the axial zone of macrotempleta
discontinuities in the metal called "coarse bubbles"
(Fig 1). A fracture along the zone of the "bubbles"
appears as lamination in the form of dark thread. No
changes in structure in the zone of the defect was
noti.ced, non-metallic inclusions are absent. Studies of
longitudinal cross sections of ingots (Fig 2) indicated
that the defect is associated with insufficient feeding
of the ingot during its solidification. 3) Cracks -
usually situated in the central part of macrotemplets
(Fig 3). The defect was found to be caused by too early
transportation of ingot bogies after teeming (40 minutes)
by retaining the bogies in the casting pit for 2 hours
20 minutes this type of defect disappeared. An
investigation of the defects in tile finished parts -

Cr 49 - 56 29 - 39
Si 15 - 19 40 - 54
C 2-75 - 4-50 0.12 - 0.20
When using 12 - 20 type silicochrome 7 - 20 kg/t were added, whereas of the
40 - 50 type silicochrome about 4.5 kg/t (in the ChMZ) and about 2.3 kg/t
(in the YM) and for 30 - 35 KhGSA 6-5 kg/t were added. Whsn applying 8111..
cochromet steels of the required composition could be produced without any
difficulty and the duration of the preliminary deoxidation could be reduced
by 5 - 9 min in both plants, (i.e., by 0.3 - 1.5@ of the melting time). TY&
amount of chrome, manganese and silicon scale is practically the same as
for the conventional method (in Ziatoustovsks Gr 181,.1f, Mn 20%, Si 32%, in
Chelyabinsk3 Cr 19%, Mn 25%, Si 38%). The lower amount of chrome scale in
the ZMZ can be explained by the higher residual chrome content of the metal
before deoxidations 0-13 - 0-31% as compared to the values obtained in the
ch= t 0.06 - 0.13%. In order to obtain an optimum economical effect, when
melting medium-carbon chrome steel, the amount of 20 type sill cochrome should
be 11 - 13 kg/t in the ChMZ and 6.5 - 9,5 kg/t in the ZMZ and the silicon
used in conventional melting be replaced by blast-furnace ferrosilicon. Men

fining under this slag layer. The metal was poured into molds for 1-115
and 2.65 t and then the steel was rolled into squares of 160 and 175-200 mm.
The macrostructure and the longitudinal quench crack of the specimens were
satisfactory. It was found that hydrogen considerably affects the formation
of intercrystallite cracks and their shape. The new technology made it
possible to reduce the hydrogen content of the finished metal to 0.90-1-58

improve the quality of ball-bearing steel differs from the conventional
method in several aspectBi the boiling period is made more intensive, pig
iron is added at the end of the oxidation 0phasev0 the metal temperature is
reduced during melting and pouring (1,530 - 1,550 C); the steel and slag
are tapped through an opening of 250-300 mm. This new method decreases
the quantity of non-metallic inclusions, oxides, etc. in the metal (the
amount of specimens with inadmissible contents of oxides decreased from
14.9-16.0% to 7.7-6.0% and the amount of globular enclosures from S-7-7.5%
to 0.55-2%y. 2. The cauoes of the low notch toughness of the 3CxrCHA

TEXT8 At the end of 1957, the Chelyabinskiy metallurgicheskiy zavod (Chel-
yabinsk MetaLlurgical Plant), in cooperation with the TaNlIChM introduced a new
for producing LUX15 (ShKhl5) grade ball bearing steel, applying lower

.!,jelons. F6uring was carried out with skin-formaticn at the metal surface when
the 1cwer third of the ingot mold was filled. However, the new method increased
the surface defeats of the new metal producing distortions on the ingot, flaking
and 3ra,@?klng in the rolled product. The rate of rejects due to surface defeats
in the m9tal poured at 1,530 - 1,5500C was 1.47% as compared to 0.21% of the can-
ventional metal. Wnen the causes of these surface defeats were investigated It
wag f,@vnd that the distortions occurred mainly in that part of the ingot which

uoBe of skin formation. To eliminate these surface defects it was decided to put
wsoden frames In the ingot molds and to fill the lower part of the ingot mold
rapidly, then slowing down the pouring speed and Increasing it again when filling
the upper third of the ingot mold. The use of wooden frames reduced the percent-
age of rejects due to surface defects to 0.08% as compared to 1.47% in metal
poured without wooden frames. The new method has been applied also for trans.-
former steel and it was possible to reduce the percentage of surface defects in
47.his steel from 2.5 to 0.5% using wooden frames in the ingot molds.

TEXTs In the 16KhGT grade steel detects In the forjn of blisters and twists
were found, mainly In the top part of the ingot, re-julting in 7% rejects. The
defects in the ingot body were most probably due to pouring in such a way that in
the ingot mold top a skin was formed at the walls. When 5-ton ingots were cast
the defects de'cr@ased due to the shorter pouring time resulting in a smaller tem-
perature differenie between the beginning and the end of the casting process. An
efficient measure to prevent these defects was topping the ingots at 19% of their
height instead of 17%. Another type of defeot is the "tengue" observed on the
face of the ingot when cutting the hot metall. In the 5-ton and 6.2-ton ingots
this type of defect increased to 25%. Wen investigating these "tongues" on

etched longitudinal and lateral macrosections and on t1he longitudinal hardened
fracture, It was found that they were actually laminations of the central zone of
the ingot. Maorostructuraltests revealed at the place of laminations an accumula-
tion of non-metallic impurities, extending along the axis of lamination. More-
over, Investigations of the longitudinal hardened frazture showed that this lami-
nation is an internal defect of the metal connected with the crystallization of
the ingot. Therefore, tests were made to determine the character of 6rystalliza-
tion and the structure of 18-30KhGT grade steel ingots. The crystallizationpr(>-a-
ess was studied in 6.2-ton ingots by the tilting method, radiometry and tempera-
ture tests. In the radiometrio method (Ref. 1, M.I. Kolosov, A.N. Morozov, et
al., "Rate and Sequence of the Crystallization of Killed Steel-Ingotd. In the
collectioni "The Application of Radioactive Isotopes in Ferroug Metallurgy",

ture during crystallization was recorded at distances 665, 1,125 and 1,425 mm
from the riser, with platino-rhodium-platinum thermocouples, protected by double-
wall quartz tubes between which graphite rings were fitted at each level. During
crystallization a double-phase zone formed along the axis of the Ingot. The con-
