present to obtain compact metallic deposits, refined metals, metallic powders and
alloys and protective and decorative coverings. Development of electrochemical
technology proceeds in the direction of further increase of current densities through
application of newp Improved types of electralyzers and electrodes, use of more
effective additional agents, methods of feed and circulation of electrolyte, appli-
cation reversing, pulsating and alternating current, as well as new e2ectrolytes, new

"Means of Intensification of electrolytic refining of copper" - indicates it is
possible to outline the following main directions of works In this field: increase
of temperat*re of electrolyte to 60-650C with simultaneous closing of the mirror electro-
lyte; suppo4ng of concentration H2SO on a level of 200 9/1, and CuSO4 5420 to 140 G/1;
owing to increase of quality of servicing of baths a decrease in interelectrode distance;
during abundant slime formation chang! of direction of the circulation of electrolyte
in baths downward; introduction of sediment and filtration of -electrolyte; improvement
of quality of matrix sheets and anodes; use of anodes with lowest possible quantity of
lead and nickel# facilitating passivation of anodes; introduction of continuous dosage
of additional agents in optimum concentrations; lowering of concentration of nickel
in solution.

lations on a krictly theoretical basis. For increased accuracy in
determining the behavior of the system in an oscillatory state, the
saturation characteristics of the piping is introduced.,.aa condi-
tioned by the finite pump output. In solving the problem, use was
made of the electronic analogue (MY-M). To evaluate the accuracy of
the results obtained the same analognalk. was used to obtain the so-
lution of the Vyshnegradskiy problem which was in complete agree-

TITLE: On the Mechanism of Effervescence of Steel (0 mekhanizme

PERIODICAL: Tr. Sibirsk. metallurg. in-ta. 1957, Nr 4, pp 119-141
ABSTRACT: To solve the question of the location of the development of
the oxidizing reaction of C, the critical sizes of the bubbles of
CO corresponding to the equal probability of their formation
In the bulk of liquid steel (BLS), on the interface between the
metal and the slag (IMS), and on the solid surface (SS) are
compared. At the IMS, under the most favorable conditions
(size of the angle formed between the convex slag layer and
the horizontal surface being 1200, and the surface tension of
the slag being one-fourth that of the metal) the critical size
of the nucleus Increases 20-fold as compared to its size in
BLS; on a smooth SS it is still lower (at a contact angle of
1400 it is only one-fifth). The nuclei formin on these inter-
faces as well as in BLS are very small (1* ICr - ZO* I cm

super saturations thousands of times greater than the existing ones. Only on
a rough surface with pares of > I ~L is the appearance of nuclei capable of
growth possible. The surface oxidation of C is dependent on the presence of
porous particles on IMS. To verify these conclusions the composition of the
metal was determined at different depths in the batht of an electric arc
furnace of ZO-ton capacity. The variations of the concentration of C, Mn. P.
and S in the oxidizing period rarely exceed the analytical errors. The non--
uniformity in 0 content (( 101 top - 101 bottom)' L 01 mead. 100 attains
501,70 and decreases witn an increase in the intensity of effervescence. In
the upper levels of the bath , the excess [ 01 (above the equilibrium with
C) is approximately constant independently of the time of the addition of
the ore, which testifies to the predominance of the development of the
reaction on the floor of the furnace.

vyplavki elektrostali iz nikel'soder zhashc hey kritsy)
PERIODICAL: Tr. Sibirsk. metallurg. in-ta, 1957, Nr 4, pp 142-157
ABSTRACT: A 10-ton basic arc furnace was employed for smelting four
batches of Cr-Ni-Mo steel. Two batches were smelted in ac-
cordance with standard procedures, whereas the smelting of
the other two batches was carried out with a charge containiny
60 and 6416 of blooms with the following composition: 82.5-86.876
Fetotal, 0.99-1.061,16 Ni, 0.19-0.3876 Cr. 1.65-1.86176 C. 0.09-
0.1ZO/o S, and 0.17-O.ZZ% P. The nonmetallic components of the
blooms amounted to approximately 20% and contained up to 45%
SiO?. The technology of experimental smelt,ngs differed from
the standard procedures in the following respects a)introduc-
tion of 200-400 kg of lime and 100 kg of Fe ore into the charge,
b) addition of 500 kg of lime and 150-200 kg of ore during the
melting stage; c) discharging the slag twice during the melting
Card I/Z stage-, d) a P content of 0.067 and 0. 1 161o after fusion.

e) introduction of an oxidizing stag in amounts equivalent to 41.7 and 36.97o;
f) a reduction in Mn content to O.OZTo at the end of the boil stage; g) a reduc-
tion in S content to values of 0.064 and 0.0731o after fusion. and 0.031 and
0.02976 prior to the beginning of the finishing stage; h) reduction in Ni con-
sumption by 5 kg/t of steel and an increase in the consumption of Fe-Mn by
8 kg/t of steel; i) increase in the time required for smelting of I ton of
metal, under current from 37 to 46 minutes; j) a 30-3519 increase in con-
sumption of electrical energy coupled with a reduction in output of liquid
metal from 95 to 8016. The finished metal of the experimental smeltings
was characterized by an increased P content and a reduced concentration of
gases and nonmetallic inclusions. As evidenced by macro inspection, sus-
ceptibility to flakes, mechanical properties of longitudinal and transverse
specimens at normal and reduced temperatures, by anisotropy and temper-
brittleness tendencies, the metal produced in experimental smeltings does
not differ from metal obtained by standard smelting methods.

PERIODICAL: Tr. Sibirsk. metallurg. in-ta, 1957, Nr 4, pp 171-178
ABSTRACT: Dimensions of bubbles breaking away from the bottom of a
steel smelting furnace were calculated for various conditions of
wettability of the furnace bottom by liquid metal. The volume
of the bubbles increases proportionately with the third power of
the contact angle 'Pand amounts to 10-800 mm3. By taking this
function into consideration, the well-known formulae for the
volume of the bubbles evolved and the degree of agitation of
metal produced by the bubbles were further refined. It is dem-
onstrated, by means of a specific example, that as the angle 44
varies from 200 to 1400 the volume of the bubbles appearing on
the surface increases approximately three-fold, while their
capacity for agitation of the molten njetal increases by 50%.

declines to 0.0256 when ready for tapping, and further to 0.0176
during tapping. In medium-carbon steels (MCS), 1 0 1 was
0.041-0.0116 at the end of the oxidizing period and dropped to
0.01jo when it was time for tapping. In high-carbon steels (14C.S)

that only in the LCS did ( 0 1 diminish to less than equilibrium with C during
period of Fe-Si and Al deoxidation, while in all other cases it was higher
than the values in equilibrium with C. The most pronounced diminution in( 01
occurred during the slagging off of the oxidizing and the making of the white
slag. Upon deoxidation of the Si, the LCS first displayed a pronounced dim -
inution in [01 , which later slowed down or ceased completely, while in MCS
a smooth drop in[ O)was observed, and in 14CS there was no change in ( 0 1 in
the ma ority of cases. During tapping there was a pronounced reduction in

and increases in [0) were observed in HCS. On deoxidation, the Si contents
of NI in LCS rose on the average from 0.0038 to 0.028816 and then declined to
0.0116 at the time of Al addition, subsequently rising to 0.02921o, and declin-
ing again to 0.0116 during tapping. A similar regularity was also observed in
MCS, but in 14CS the NI contents fluctuated - 0.0071o, did not increase after
Si deoxidation, and increased after Al deoxidation to less than 0.01016. The
data obtained are taken as good cause for recommendation of intensified
deoxidation of the steel at the outset of the reduction period by use of com-
plex deoxidizers and addition of Fe-Si to the slag in addition to Fe-Si, as
this makes for a shorter heat. Bibliography: 7 references.

ABSTRACT: A theoretical analysis shows that the minimum amount of Si
needed to deoxidize steel depends upon its C contents: When C
rises from 0 to 0. 1~9 it increases from 0 to 0.0816; when the C
content is 0. 1-0. 16016. 0.08'16 Si is required, while with 0. 16-
0.3059 C the Si requirement is 0.08-0.231a. and with 1.4-4.316 C
the amount of residual Si diminishes from 0.23 to hundredths of
a per cent. To verify the theoretical conclusions, experiments
are conducted on the deoxidation of carbon steels of various
compositions melted in an 80-kg electric furnace with 180-kva
transformer. 130 experimental ingots of 2.2 kg weight were in-
vestigated and confirmed the theoretical principles established.

P&RIODICAL: Stall, (1959, Nr 4, pp 323-327 (USSR)
ABSTRACT: An investigation of the possibilities of intensifying the
electric smelting process carried out on the Kuznetsk
Metallurgical Combine during 1956-1957 is described.
For this purpose 100 heats of structural steels were
carried out (table 1) in which the following methods
of intensification of smelting were tested: 1) the
use of oxygen for the oxidation of admixtures;
2) combining of the end of the malting period with the
beginning of oxidation; 3) dephosphorisation of metal
during melting;
4
decreasing the amount of burned out
.
carbon (up to 0 2% ; 5) intensification of the
~
deoxidation by the use of a preliminary precipitation
deoxidation with complex deoxidants and with an addition
of powdered ferrosilicon after the making of a reducing

ABSTRACT: The choice of a tantalum-niobium alloy wa5 dictated by the fact that these
metals have a resistance at 200 about 2-5 times greater than that of tungsten and
riolybdenwn, and that -they recrystallize without an Increase in brittleness, since the

industrial properties than tunGston and molybdonum; the ductilitAf a tantalun base

alloy with from 30 to 35% niobium has bo~in found exporimontal1y to have the higha3t

Title, .1 Hydraulia jump and boundary layer separation
Periodical DAL AN SSSRj 961 Ed# 6p 1121 - 1124, June 1954
Abstract t It was experimentally established that the transition of a flow from tur-
bulent state into stable is a favorable condition for the origination of
the complex phenomenon called the hydraulic jump. If the free surface
of the stream increases sharply and the pressures are nonuniformly die-
tributed in depth then we have a hydraulic jump with surface roller even
during calm condition of the stream prior and after the hydraulic jump.

ABSTRACT: A hydraulic method of design calculation is described for ejectors
equipped with a cylindrical mixing chamber for subsonic velocities
of gas flow. The results of an experimental investigation of a gas-
injection nozzle cited in the paper agree very well with the calcula-
tions. A nomogram designed for a natural-gas - and- air -mixture
injection nozzle is included to facilitate the solution of the pertinent
equations for the ejection flow. Bibliography: 18 references.

ABSTRAM The authors investigated the length of a recirculation zone
originated in discharging water from a cylindrical nozzle
into a circular cylinder of a larger diameter. The water
discharge varied from 0-5 to 10 cu m per hr. With an increase
in Reynold's number from He a 10000 to He a 509000# the
length of the zone increases, first rapidly and then more
gradually. At Re> 50,000 the length of the recirculation
zone is independent Of the Re-value. The authors derive an
empirical equation which shows the dependence of the relative
length of the recirculation zone on the ration of diameters.,

lamps and have also a higher radiation capacity (9 koal/sq cm), while the
dryin costs are reduced 6 - 10 times. However, when placing the test spec-

period of 20 minutes, the core center was not dried. Upon raising drying
time, the core-edges got burnt. Setter results were not obtained even when
