The behaviour of hydrogen during S/148/61/000/009/002/012
E071/E135
in the ingots teemed with the heating was somewhat lower than in
the usual ingots; in the remaining parts of all three ingots the
hydrogen content was approximately the same. The average hydrogen
contents were as follows3 in the usual ingots 4.98 cm3/100 g;
in the ingot teemed with electroslag supplementary feeding
4.05 CM3/loo g; in the ingot teemed with electroslag heating
4.o9 cm3/loo g. It is concluded that electroslag-heating or
supplementary feeding of the head of the ingots secures the
transfer of some of the hydrogen from the metal to the slag, thus
lowering somewhat the concentration of hydrogen in the whole
system of the ingots but particularly in their head part, The
transfer of hydrogen into the slag bath takes place not only due
to the Perrin-Tochinskiy effect, but also due to the electrolytic
transfer of OH- ions and their discharge on electrodes during the
half period when the electrodes are acting as anodes. O.A# Yesin,
V.I. Yavoyskiy, G.N. Batalin and V.S. Baykov are mentioned for
their contributions in this field.

TITLE: Diffusion of carbon and oxygen in liquid steel
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy,
Chernaya metallurgiya, no.11, 1961, 38-44
TEXTt In order to establish the relative rates of diffusion
of carbon and oxygen in liquid steel (which are important in
explaining the mechanism of oxidation of carbon) the authors made
an attempt to measure the diffusion coefficients of these two
elements in molten iron. The diffusion coefficient of carbon
was determined usin- C14 by the method of orthoradiography.
Since capillaries of 5-6 mm in diameter were used the influence
of convection was not eliminated and out of numerous experiments
only 11 results could be used for the determination of the
coefficient. This was found to be equal to 4 x 10-5-1.92 x 10-4
cm2/sec, which is close to published data. The diffusion
coefficient for oxygen was determined by the method of semi-

infinite rod with a constant source of oxygen (blowing of oxygen
on the surface of iron for one minute at a rate of 0.5 -f/min).
It was found that the diffusion coefficient for oxygen Is higher
than that of carbon by about two orders, namely
(3-0 - 7-8) x io-3 cm2/see. The results invalidated the
generally held view that the diffusion of oxygen is slower than
carbon. Bearing in mind possible experimental inaccuracies, it
can be stated that the diffusion of carbon in molten iron is
not faster than that of oxygen. S.Z. Bokshteyn, I.S. Kulikov
and A.A. Zhukhovitskiy are mentioned in the article.

TEXT: The influence of boron and vanadium on the solubility
of hydrogen in liquid iron was investigated using an apparatus
described earlier by the present authors and Yu.V. Kryakovskiy
(Ref.1; Izv.vuz Chernaya metallurgiya, no-7, l9bl) at hydrogen
pressures of 18-41 mm Hg. The accuracy of the method was tested
by measuring the influence of silicon on the solubility of
hydrogen in iron. The results obtained agree well with the
literature data. The solubility of hydrogen in liquid iron at
1560 and 1655 OC, as well as in solid iron near its crystallisation
temperature, was determined. The respective solubilities were:
at 1560 OC, 27-45 cm3/100g, at 1655 OC, 30-80 ctr,3/loog, and in
solid iron 12.2 cm3/lOOS. The influence of up to 9-30"1 vanadium
was studied at 156o OC. In liquid Fe + V alloys3 the solubility

of hydrogen increases with increasing vanadium content, and for
alloys containing up to 60,~, vanadium it is proportional to the
square root of hydrogen pressure. The temperature coefficient
of hydrogen solubility for the alloys is lower than for pure
iron. Additions of boron to liquid iron (up to 0.2~~) have no
influence on hydrogen solubility.

PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy.
Chernaya metallurgiya, no-3, 1962, 60-67
TEXT: The surface activity of rare earth*elements i 'n iron is of
importance from the point of view of their modifying effect which
is caused by preferential adsorption of surface active
components on faces of growing crystals, inhibiting their growth.
In multi-component systems, changes in the surface tension could
.be.due not only to the adsorption of a given component but also
due to various physico-chemical processes taking place in the
melt (e.g. deoxidation,dosulphurization, changes in the activity
of other components),*for this reason the influence of rare
earth elements on the surface tension of specially purified
liquid iron was measured (not more thant 0.020Yo C, 0.015% Mn,
0-005% S�, 0.0028% P, 0.002% S and 0.003% 02)- The method

consisted of measuring the maximum pressure of gas bubbles in
vacuo or in a controlled atmosphere. Well purified argon was
used for blowing bubbles and as a protective atmosphere. The
apparatus and experimental procedure are described in some detail,
It was found that cerium and lanthanum are surface active. In all'
cases, first additions of cerium (up to 0-455/6) lower the surface
tension of iron by 100 to 120 orglcm2, whilst further addition of
cerium increases the surface tension of iron due to its reaction
with oz,~ygen and sulphur. Lanthanum acts similarly but a
decrease in the surface tension was noted only after the first
addition (0.1%). This is explained~by a higher deoxidizing and
desulphurizing ability of lanthanum In comparison with cerium.
The influence of the admixtures present in iron on changes in the
surface tension on the addition of rare earth elements (Ce, La,
Nd*, Pr) was demonstrated by using ordinary armco iron and
carrying out experiments without a.protective atmosphere. In this!
case additions of rare earth elements-caused an increase in the-
surface tension of iron; only irk a few cases was a small decrease
observed after the first addition. This indicates that the

Influence of rare earth E071/E435
increase in the surface tension is associated with the
deoxidation and desulphurization of the metal (in the case of
deoxidation confirmed by analysis). The modifying influ6nee of
additions of rare earth elements was confirmed on special heiats-
of X23H18 (Kh23N18) steel made in a 30 1c9 induction furnace,
The grain size of the metal in the cast state was found to be
diminishing with an increasing amount of rare earth element added.

TEXT: The new "electroslag-heating" method described by G.S. Tyagun-BelolB

chamotte-and 55% fine-graded coke is spread on the metal surface, in an amount
of 2 kg/ton steel, ther,~14 kg/zon slag forming materials are added. Through
the layer forming _^rom t&se elements which smelts and becomes electro-conduc-
tive, a current' of indusirial frequency is led. The slag layer developing' In
the dozzle of the mold is 80 100 mm thick. In the electroBlag-heating method

carbon electrodes (50 -,150 mm in diameter) are Used. If this process is com-
bined with additionai feleaJng, 80 - 100-mm'diameter self-baking electrodes of
the same grade that 'Li being smelted are used. The ingots cast by the first
weighed 7-55 cons, those of the combined method 7.3 - 7.4 tons, while the
standard ingots were 8.2 tons. The slag forming elements used viere chamotte
powder, lime, fluorite., Shrinkage cavities were not found In the ingots cast
with .21ectroslag heating, but the highest density was obtained, when electros~lag
heat_'..~ and additional feeding were applied. The test Ingots and one control
ingo. .:-:iz,e examined for chemical nonhomogenelty, the amount of residual hydro-
ger., --ckling and mechanical properties. The positive liquation of carbon was
75/5 in the ingot heaas subjected t6 additional feedings 2% in case of electroslag
heating, and 200% for the control ingot. The corresponding values for the sul--
fur content were 0.0 and 10% and for phosphorus 0.5 and 50%. The decrease of
liquation can be explained by the activity of the slag layer, which absorbs the
additives from the smelted metal at their interface. This process Is consider-
ably intensified.by the convective flows circulating at a rate of about 4 M/min
in the ingot mold during crystallizations entraining liquid metdl from the low-
er, solidifying parts of the ingot upward to the riser, i.e., to the electrical-

ly heated slag layer. For the same reason the hydrogen content of the ingots
also decreases. In the test ingots produced with electroslag heating the hydro-
Sen content was 11.09 c1n3/100 g, in the ingot with additional feeding 4.05 c~3/
/100 g, and in the control ingot 4.98 cm3/100 g. The effect of convective flows
was investigatcd by radlo~netry, using a p32-50 millicurie-isotope. As to mecha-
nical properties, Tht., highest values were found.in ingots treated by electroslag
heating, witho%.-.-. additional feeding: crB - 50 - 56 and d-s = 37 - 42 Rg/mm2;
in the riser part of the ingot the highest mechanical parameters were obtained
for Ingots with additional feeding: (fB = 50 - 55, ds = 40 - 45 kg/mm2. The
effect of the quality of current on the properties of the Ingots was also stud-
ied by ieans of a d-c welding generator (1,100 amp, 40 v) and 3.4 ton lOG2SD in-
gots. 7he highest pararie-Lers and the most uniform distribution of elements were
found a Ingots hvated by direct current with a direct polarity. Similar re-
sults can b, obtained also with alternating current of Industrial frequency,
which -s important from the practical point of view. If electroslag heating of
the riser is applied, the saving in metal is 6 - 7%; if additional f6eding is
also a,jplled, it is 10 - 11%. The riser volume can be reduced by 3 - 5%.' It is
also possible to disperuie with the riser complotely. The methods should be ap-

"40KMIA" structural steel 1 kg/t ferrocerium. and calcium silicon added during the
-!finishing period to an 18 ton, electric furnace,,prevented hairline cracking. The
lauthors assume that deoxidation during the finishing stage changes the physical

TITLE: Use of single-phase transformers in electroslaa melting installations

TOPIC T&GS: electric transformer, electroslag melting, voltage regulation, slag
Eft single phase transformer.
ABSTRACT: The recently developed,EM-2000110 single-phase transformers used for
the electrosleg refining of metals are superior to the three-phase transformers pre-
viously employed for this purpose. They have a larger number of voltage stages which,
moreover, can be switched under load. In this connection, the authors present the ra-
sults of an experimental investigation which shows that during the melting the voltage
in the slag bath tends to increase somewhat (8-10 v), which leads to a corresponding
increase in power requirement and in the temperature-of-slag and metal--as-V611 ii a

rise in melting rate, which results in an increase in the depth of the molten pool
with all the adverse consequences-that this entails. To compensate for the rise in
voltage, and also for instantaneous fluctuations'in power-system voltage, the trans-
former stages are periodically switched at the optimal time instant during the melting
so as to maintain a fairly constant power level. This is accomplished with the aid of
an efficient current regulator. As a corollary, a basic requirement for an effective
electroslag melting: stability of the electric regime, must be redefined. Now this
stability does not mean a fixed level of such parameters as current intensity, voltage
or electrode feeding rate, throughout the melting process. What is necessary rather
is a-continuous,-flexib.le control of the variation in these parameters during the

ABSTRACT: Oriented crystallization is one of the chief advantages of the electroslag re-
melting process, but it r(hquires the observance of specified conditions. Thus, the optimal
depth of the molten metall bath must be one-half of the diameter (side) of the crystallizer,
for-ingots weighing up to 1000 kg. The optimal form of the molten metal bath in the case of a
cone-shaped crystallizer is assured by maintaining a constant linear rate of ingot build-up,
which can be done by_gradually reducing the elect-rode feed rate, on the basis of the equation:
Vb =' Vr. b. ` Ve 8 be 8 where Yb is the linear ingot build-up rate: Vr. b. is the rate of

cross sectional area of the crystallizer (decreasing with height). The constancy of the optimal
shape of the molten metal bath is also assured by a definite ratio between the solidification
rate v. and the build-up rate vb (Fig. 1.), such that vs somewhat exceeds vb. Further, an

ABSTRACT: Tho' authors studied tho'naturo and-astribut'ion of inclusions
'.in l2Kh314F tube steel with and without additions of rare earth metals.
Three methods ware used for adding the rare earth metals to the melt:
-1) in the furnace immddiately before tapping (2-3 kg/t); 2) in the pouring
ladle (0-2-1.0 kg/t); and 3) in the mold during teeming (0-2-0.7 kg/-t)o
Macrostructural analysis revealed that addition of rare earth clemen 1 by
any wthod and in any quantity reduces local segregation of sulfur though
us-e-cl-f 1~
.the degree of improvement is highly dependent on the method 0 intro-
'Gucing the rare earth metals. For instance., additions of 3 k&/t to the
furnace gives about the same effect as addition of 0.7-0.8 kg/t to the
ladle. Additions of less than 3 kg/t to the furnace or less than O-Z-0-5
,.kg/t to the ladle have practically no effect on macroaturcture. Direct-
:introduction.of.rare earth metals during teeming has a more noticeable.

*0-5-0.6 kg/t. The mechanical properties of longitudinal specizWns were not
changed by rare earth treatment regardless of method of introduction or quantity

improvement in mechanical properties Orig. art. has: 2 figures and 1 table.
