ABSTRACTi The conditions for a rational air-blast supply into the metal
furnaoe are experimentally investigated by considering,firstly,
utili:?,ation of the possibilities offered by blast oxidation and,
secondly, regulation of both sequence and speeds in the oxidation
of the admixtures contained in the metal smelt. In the smelting
tests the influence of the main factors named in thb follow-.Ing on
the o:rder and on -the speed of oxidation of the admix-uures to pig-
iron was examined: 1.' Intensity of feeding the bath with oxygen
fou;plying speed of the oxidizin6 agent and its composition'
% )I
2.) method of feeding the oxidizing agent into the bath (refining
of molten metal or blasting of the oxidizing agent at the surface).

obtained, a part of which will be studied here. The data obtained'
clearly show the effect of temperature on the speed of carbon
oxidation in the melt and confirm the supposition, expressed at
an earlier date (Ref 2), of the existence of a temperature thre-
shold at decarburization. - At the same time, it is stated that
the conditions of feeding the bath with oxygen may somewhat
changre the influence of the temperature. In the case of weakly
oxidizing puddlJ-ngv tile influence exercised by the critical
temperatuire is less marked and increases noticeably with an in-
crease of the oxygen -concentration in the fan blast. By inteasif)~-
ing the air blast supply a noticeable increase of the decarburi-
zaUon speed at a mean temperature of the bath of somewhat bedow
15000 is observed. The testing of a combined supply of the_
oxiE 'zing agent to the bath while simultaneously blasting and
injeoting the oxidizing agent into the metal proved to be very
interesting. By one Jet a 100 % oxygen and by another jet a mix-
ture of 50 %.oxygen and 50 % carbon dioxide was injected. The
jets lead into the interior and onto the surface of the metal
nhanged place in the 'Ist and the 3rd melt section. Of the two

mixture of 50 % 02 + 50 % COV and 2) refining with 50 % 02 + 50 %
Co 29 blasting with 100 % oxygen, the latter proved to be more ef-
fective. This means that the use of a more intense oxidizing agent
for blasting the bat-*, ensuring higher absolute speeds for the
oxidation of the elements, was more effectful. The employment of
combined blasting, at both variants, lead to an intensification
of the processes of oxidizing the admixtures of molten metal.

ABSTRACT: The regularities governing oxidation of C in Fe-C melts under the in -
fluence of a gaseous oxidizer are studied by a dynamic method which
eliminates the development of secondary reactions in the gas phase.
The essence of the method lies in the forced delivery of CO? to the
surface of the metal(M~, which is melted by induction heating in an
alundum crucible mounted on a fixture in a quartz tube, and in meas-
uring the gas flow rates at the system inlet and outlet by capillary
rheometers. The actual amount of gas emitted (vf) is calculated,
with consideration of the viscosity of the gas-phase components, in
Card 1/2 accordance with the equation vf= 100 Vr / (x+ yKCO+ zKAr), where vr

the bath. However, as the intensity of delivery of oxdizer increases, the coeffi-
cient of utilization thereof diminishes. It is shown that the results obtained are ex-

to that theory the case of development of the process in Ihe region of diffusion reac-
tion, which Iof practical importance, is inhibited by the stage of delivery of the oxy-
gen to the reaction zone. The existence of a critical point ( -15000C) in Fe-C
melts, which corresponds to the temperature threshold of a sharp change in vs due
to a change in the chemical activity of the reactJng C, is confirmed.

ABSTRACT; This report deals with experiments in which a magnesite
crucible with liquid Iron was tilted and slowly rotated
(a - 10 rpm); the oxidizing atmosphere (.1-,0% CO 2 + 50% 02)
was supplied to the metal either on the siirface or by an
immersed quartz tibs into the int*vior. The emperimental plant
is illustrated -In figure 1. Figures 2 and ) show the course,
with respect to time, of the oxidation of carbon, manganese
and silicon in dapendence on the inten-sit,.r of the gas supply.
The results are as follows: With a rise in the supply of the

increases. The other variations of the experiment, rotation,
supply of gas on the surface or into the interior) proved to
be ineffective. The authors explain this cirnumstance by the
faat that the electromagnetic intermixture in the induction
furnace was much mcre intensive, and therefore concealed the
other effects including that of slow rotation.

All of the above studies brought the authors to the
conclusion that the process of oxidation of carbon,
which is dissolved in liquid iron, develops in
the diffusion region cf. reaction. Until approximately
0.1% C (carbon content in metal) the limiting con-
dition is the introduction of oxidizer from the gas
phase to the reaction surface. The tests were con-
ducted uhder the conditions eliminating any bubble
formation or'rimming'oT metal bath. The surface of
reaction practically.coin--ided with the surface of
the bath. Tne *speed of the cheMical reaction proper
(including the adsorption of' reagents in the react-Lon
layer and the desorption of the product of reactlon,
carbon monoxide) should be sufficiently high. The
gaseous particles of oxidizer arrtve at the metallic
surface, they are adsorbed on it, and they instantly
enter into a chemical reaction with the sufficiently
abundant carbon. The carbon monoxide, wnich is
formed in this process, Is desorbed in the gas phase..
When carbon content in the bath Is below the critical
value (about 0.1% C), the delivery of carbon from the

metal to the reaction surface becomes a limiting con-
dition. The einount of carbon inflow becomes insufficient
for a given flow of' oxidizer. Such a change of one
limiting condition to another (with sufficient amount
of oxidizer)'is closely related to the ch-ange of
structure of the surface reaction layer. The establIshed

TEXT: The method and the results are described of a laboratory investiga-
tion of the kinematic laws of the decarbonizing of steel under interaction of the
melt with a stream of C02 oxidizer. Experimental heats (70 - 100 grams by weigho
were carried out in a high-frequency furnace with a quartz reaction crucible.
The metal was melted in an argon atmosphere. When the'experimental temperature
was attained, a continuous stream Of C02 was fed to the metal surface from a
tube. The rate of C02 progress and the output rate of the reaction products were
measured by capillary rheometers. Periodically, the gas composition was deter-
mined by the usual volumetric method, on the basis of which corrections were
introduced into the rheometer readings. The metal temperature was measured by
an optical pyrometer; in the,course of the smelting metal samples were taken

by sucking it up into quartz pipettes. The results of the experimental heats
are represented in a table and graphically. They testify that in a definite
time interval, even at a continuous lowering of the C-content in the metal, the
decarbonizing rate remains constant. Starting at a definite instant, closely
connected with the attainment of a definite oritical C concentration, one observes
a slow-down in the process. Experiments have shown that to every given feed-
intensity of 02 to the vat there corresponds a process rate which does not
depend upon the C, content. The slow-down In the process rate should occur at a
definite critical C concentration in the metal, when a shift In the surface
reaction zone takes place. Then, less C comes into the reaction zone than can V/
be oxidized. The value of the critical concentration should increase as the
oxidizer input rate into the vat increases and should decrease as the C feed-in
to the reaction zone is intensified with an Increase in the mixing intensity of
the metal. At C concentrations in the metal below the critical concentration,
the laws of diffiision kinetics are operative with the limiting factor being trie
feed rate of oxidized C to the reaction zone. The decarbonization process
shvald depend upon the C content in the metal and obeys the kinematic equation
-dC/dT = SIV - UCY(O + l1Kx) 31 where S/V is the ratio of the reaction
surface to the volume of the vat; Kx are the rate constants of the oxidizer

input and the chemical reaction, respectively. At a very intense oxidation of
the melt the process may develop in two stages, to each of which corresponds a
definite value of ~he processrate constants. In the second stage either a
retardation or an acceleration of the process is possible. A retardation of the
decarbonizing process in the second stage is connected with the appearance of a
slag phase upon the metal surface. An acceloration of the process in the second
stage is connected with the intensillication of gas formation and stirring of the
vat,

TITLEs Kinetics of oxidation of' carbon in liquid steel under

PERIODICALt Izvestiya vysshikh ucheb,nykh zavedeniy,
Chernaya metallurgiya, no.11, 1961, 15-21
TEXT: The influence of magnetic stirring on the kinetics of
oxidation of carbon was investigated on a laboratory apparatus.
In preliminary experiments, using mercury as a liquid metal, the
most suitable position of a stator (from a two-pole motor) and
the necessary voltage to 'obtain an energetic rotation of the metal
in a small crucible were established.. Carbon dioxide was chosen
as an oxidising gas. Heats were treated at C02 flow rates of 75,
125, 200 and 325 me/min. As a starting material soft iron and
pig iron smelted from electrolytic iron were used. CAbstractor's
note:I Electrolytic iron contains no carbani how can it give pig
iron.li The weight of a charge was 300-350 9 (the diameter of
the L::agnesite crucible - 31 mm). A nozzle of 3 mm diameter was
30 mm above the surface of the metal in all heats; the position

of the metal in respect to the stator and heater was also constant.
Altogether 28 experiments were carried out with and without
stirring the metal, at temperatures of 1540-1570 OC. In some
heats the metal was stirred in both directions. Kinetic curves of
decarburisation were obtdined for each series of heats with a
given rate of supply of the oxidising gas. In the range of higher
carbon concentrations (up to about 0.2%) the experimental points
obtained with and without stirring fell on the same straight line.
The experimental results agreed well with the kinetic equation
for the decarburisation of metal at carbon contents above the
critical concentration:

The rate of oxidation of carbon d T mole/cm min ) is
determined by the rate of blowing the oxidising atmosphere
(W cm3/min), the content of oxidant (PO 2, mole/cm3) and the volume
of the metallic bath (V, cm3). The coefficient expressing the

utilisation of the oxidant n reflects the flow characteristics
of the oxidant stream and the surj-.ace conditions of the metal.
In the range of carbon concentratlons above the critical, the
rate of decarburisation is independent of stirring, and the
limiting factor is the transfer of oxidant from the stream to the
reaction zone. At carbon concentrations below the critical, the
limiting fact-or is the transfer of carbon to the reacting surface
and the experimental results conform to an equation;
d(C] = YC . S/VM [c] (2)
d T
Yc = -2-303VM/S Alog IC3 (3)
The rate of decarburisation depends on the reacting surface of
the metal (S, cm2), its volume (VM, cm3) and is directly related
to the concentration of carbon CC], mole/cm3. The effect of
stirring can be evaluated from the ratio K of the diffusion
coefficients of carbon in liquid metal, with (y.) and without (y.)

stirring, corrected for the change in the surface area of the bath
S/S".
Yc c
The influence of electromagnetic stirring can be presented by a
general equation expressing the dependence of K on the voltage
applied to the stator (U):
K = A . Un + B (5)
where A and B are coefficients, n is the power index. Under
experimental conditions n < 0.5. According to experimental
data (Fig.6) the influence of stirring depends on the applied
voltage and the rate of supplying oxidant to the metal.
Electromagnetic stirring can also speed up other refining
processes providing the concentration of an admixture is below
the critical one. I.M. Kirko is mentioned in the paper in
connection with his contributions in this field.

TEXT: A study was made of the gas inclusions in Fo-C-0 molts
in which two methods were compared, (a) determination of the
anomalies in the oscillations of a freely damped suspended body
immersed in the melt and (b) determination of the anomalies in a.
rotating magnetic field. The melts were obtained by adding
graphite and partly oxidized electrolytic iron to technically pure
iron. In (b) the probability K? of the formation of
heterogeneities in the melt i6 proportional to ratio of the number..*
of oscillations with disturbances to the total number of
oscillations. Similarly, with (a) the probability KV is
proportional to the ratio (if the number of oscillations not

the heterogeneity is due entirely to the decarburization reaction.
In (a) the difference between.the maximum and minimum anomalies
Lap was examined and was found to. be as good a qualitative
guide as X P to heterogeneity. In (b) the sum of the maximum
positive and negative anomalies Z~aV was also examined and was
found to be preferable to K.,) as a guide. Both methods were
sensitive to the appearance of inclusions due to the formatian of
nuclei followed by the growth of small bubbles on them. From
Frenkells theory of liquids, it is concluded that both methods
show the early stages when, in the presence of excess oxygen,
cracks and discontinuities 121 'the liquid develop into nucleating
cracks and holes from which fine bubbles appear. This mechanism
;.has been confirmed by determination of changes in viscosity.

ABSTRACT: Partial or complete deoxidation of rimmed steel in molds'
by aluminum or silicon is one of the means of reducing its chemical
inhomogeneity and of increasing the yield of quality metal. The
corresponding experiments were carried out with 18-ton ingots of
;08kp rimmed steel deoxidized by ferromanganese in a furnace, and
additionally by aluminum (130,g/ton) in the ladle. Semikillied and
killed steel was produced by adding 0.2 and 0.4 ks/ton, respectively
of aluminum that during pouring into moldol the metal of two ingots
.was deoxidized in the mold by an 092 kg/ton addition of 45% ferroal.

specific
silicon. All ingots had a dense crust, 20-40 mm thick. A
,.feature of the ingots of k*illed and samikilled steel was the presence
..of a more or less dense bridge. A partial preservation of this bridge,
:by limiting the crop to 2%, will ensure welding of shrinkage defects
;during rolling, thus increasing the yield of quality metal to 93%.
.The macrostructure of the ingot deoxidized by ferrosilicon.was close
~ito that of the rimmed-stael Ingot; the semikilled' steel macro-
istructure was close to that of the killed. Ferrosilicon in the amou Int
.of 0.2 kg/ton of steel does not ensure a sufficiently uniform
:distribution of sulfur and carbon in low-carbon rimmed steel. A
amount of ferrosilicon would increase the silicon content in
ithe steel and impair,its plastic properties. The addition of 0.4 kg
Al/ton of rimmed steel sharply reduces the inhomogeneity of the
iingot with respect to its sulfur and carbon content. A larger
!addition of aluminum (0.9 kg/ton) has no further effect on ingot
;inhomogeneity but is needed to neutralize the nitrogen and obtai
Inonaging steel. However, the ingots of the steel deoxidizod by
:aluminum have a highly nonuniform distribution of aluminum, which in
low-cArbon steels containing lose than 0*02% residual At can promote
:strain aging. Orig. art. has: 3 figures and 2 tables.

ABSTRACT: This investigation deals with measurements over a. broader temperature range
and for a greater number of metals than the study by V. V. Baydov and L. L. Kunin (V sb.
"Teoriya metallurgicheakikh protBessov, 11 vyp. 40, TsNHChM, 1965, 94-104). To this end,
quartz rods as well as rods of metallic tungsten (coated with silver to protect it against
dissolution in the molten metals) were employed as the guides for the ultrasonic waves. For
most molten metals the speed of sound decreases in a near-linear manner with increasing
temperature. But for Bi and Sb over a certain temperature range above their melting points

speed of transmission of the sound pulse is determined not only by particle mass but also by
the forces of cohesion between particles. These forces are estimated according to the heat
of vaporization or sublimation. Analogously, one of the most important thermodynamic cha-
racteristics -- is-.3thermal compressibility, :may be computed on the basis of data on the speed
of the ultrasound, density, and specific heat. The compressibility of molten metals, like that
of *911 megIs, periodically increases with atomic number; certain alloys, however, e.9.

accomated for 17.5% of world steel production. In pig-
iron production new capacity played an important part in
comyensating for temporary raw-material deterioration in
1957, the average size of furnaces increased from 639 m3
in 1951 to 715 0 in 1955 and 844 m3 in 1958; the propor-
