ABSTRACT: The Electric Welding Institute im. Ye.0. Paton of the Acad-
emy of Sciences, Ukrainian SSR,has developed a method of
making ingots by continuous build-up of metal in a water-cooled
copper crystallizer, using an arcless electrical slag welding
process. The heat source is fused electrically- conductive
slag, through which an electric current is passed from a con-
surnable electrode to the ingot. Wires of 5-8 mm diameter
may be used as the electrodes. The alloying elements are in-
troduced in the form of wire or granules. The electrode and
the alloys, immersed in the slag, attain a temperature of up
to 20000C, fuse, and form an ingot. The ingot descends as it

weight of the ingot. This method may also be used to cast hollow ingots for
tube manufacture. An equipment, the R-813, has been developed to cast
round solid and hollow ingots of 135-300 mm diameter, 1500 nam in length,
at an output of 150 kg/hr. If the cornposition of the smelted steel includes
Ti or Al, the slags used contain CaF2-CaO-Al2O3 compounds. The m.p.
and viscosity of the slag have a significant effect on the surface quality of
the ingot produced. The longitudinal orientation of the crystals and the ab-
sence of axial porosity, scabs, and cracks contribute to make this a metal
of optimum plasticity in hot mechanical treatment. The area of application of
this method is the production of tough and resilient steels and alloys.

ABSTRACT: With reference to existing data, desulfurization of liquid metal
in electric slag welding is discussed and experiments are de-
scribed which were carried out on electric-slag remelting of
"40"-grade steel electrodes in a water-cooled crystallizer.
The following conclusions are made: DeBulfurization depends
on the kind and polarity of current, i.e. it is more intensive
with a.c. and 'ess intensive with d.c. of inverted polarity
(plus on the electrode). Desulfurization of metal was not ob-
served with 2urrent of direct polarity (minus on the electrode);
in this case,, eVert passage of sulfur from slag into metal was
poesible. Replacement of CaO by KgO in the slag on a CaF2
basis does not reduce its desulfurizing capacity and can be
recommended, as such slags are less prone to hydration. The
authors thank Doctor of Technical Sciences O.A. Yesin for
Card 1/2 his valuable advice.

ABSTRACT:
Card 112
Information is given on a new method to improve the properties
of various steel grades and alloys with the use of electric
slag melting of electrodes in a water-cooled copper crystal-
lizer. Rods can be obtained which are heavy and large in
diameter. The most important advantage of the new method is
the possibility to use alternating current. It was first
introduced in May 1958 at the "Dneprospetsstall" plant on a
special electric slag remelting device.designed by the Insti-
tute of Electric Welding imeni Ye.O. Paton. The authors
thank Senior Laboratory Worker L.I. Belyatsev and other wor-
kers from the Yuzhno-trubnyy zavod (Southern Pipe Plant),
them Novo-Kramatorskiy mashinostroitellnyy zavod (Novo-Krama-
tcmkj~rMachinebuilding Plant) and "Elektrostall" plant for
their cooperation in developing the new method.

..ABSTRACT: As the existing dL-a does not determine the effect of flux
composition and its electric conductivity on the technical-
economic characteristics of the electric slag welding process
with large section electrodes, special tests were carried
out with slags-of the CaF2-A1203 system. The effect of slag
composition in the electric slag process was investigated
with the use of grade 45 steel electrodes of 90 mm diameter
in a copper water-cooled crystallizer. The tests are de-
scribed in detail and the following conclusions are madet
1) in fusing with tldc!k elentrodea, the reduction of
the electro-conductivity of the slag leads to an increase in
temperatures of the slag bath, increased productivity and a
reduced consumption of electric power at the same electric

charges 'hetween the electrode tip and-the metal pool. On the
basis of results obtained, the use of CaP2-A'203 fluxes con-

ABSTRACT: This article refers to results of the penptration of hy-.
drogen through the slag of steellMAIM9T , in the process
of electric welding, and investigates the use of differ-
ent types of flux. It emerges that with the hydrogen
penetrating into the metal, the amount of titanium --resi-
due increases. The probable formulae for this oxidation
are given under (2) and (3). Then the interrelation be-
tween the hydrogen content o' the various types of flux
(compiled in Tab. 1) and the titanium content of the
netals in question are dealt with. The permeability was
measured in atmospheric air, Argon and saturated vapor

ANF-1P is explained by its better desulfurizing capacity due to Al 203 lower-
ing the malting point of flux and raising the slag pool temperature . The
effeot of ANF-1P and AN`F-6 on the content of oxides, silicates and globular
inclusions was equalq and of the AN-29 weaker (Fig. 2). Non-metallic in-
olusions rose to the surface in the process, and the top portion of the in-
gots was contaminated more than the bottom, particularly by globules in
remelting with AN-29 flux. The following conclusions were madet
1. It has been proven on the example of ball bearing steel ShKh15SG that
metal is purified from oxides, silicates and globules mainly due to the in-
olusions rising to the surface and the purification degree depends on the
speed of the ingot formation, 1.e.,on the speed of the crystallization front
motion, and the orientation of the crystal growth (axial or radial).
2. The desulfurizaticn degree depends mainly on the de9ulfurizing capacity
of the flux, and not on the speed of melting. 3- It can be stated that it

eleotro-chemical solving. The total gas content was trice lower than in the
ihitial metall the nitrogen and oxygen contents were reduced more than the
hydrogen content. Apparently, oxygen is being eliminated in the process with
floating oxide inclusions, and nitrogen and hydrogen can separate with bubbles
forming on the surface of the growing metal grains. Nitrogen separates from
metal easily when the metal contains no components forming stable nitrides
(titanium, niobium). Nitrides having a higher melting point and larger vol-
ume do not coagulate and stick more easily in interaxial spaces. This ex-
plains the different quantity of nitrogen eliminated from the two steel grades.
The following conclusions are mades 1) The electro-slag process considerably
reduces the gas content and nonmetallic Inclusions in both steel grades.
2). It raises the ductility of austenitic stainless steel grade and consider-
ably reduces the anisotropy of mechanical properties. 3) The ductility of
the remelted metal at hot deformation temperature is 30-40% higher than that
of the initial one. There are 8 figux-es, 5 tables and 5 Soviet-bloc refer-

TEXT: Tb:ree reasons for oxygen entering the metal in the electro-slag re-
melting process are pointed out and discussed: unstable oxides which may be
present in the CaP2-s-iretem fluxes used for the process can cause oxidation
of some elements; scale or rust on 'he consumable electrode may introduce a
large quantity of oxygen, which is illustrated by examples of very high po-
rosity in remelted armco steel; oxygen from ambient air above the slag can
get into the metal under the slag in two ways - through oxidation of "he'
electrode surface and directly through the slag layer by the formation of
high oxides of iron, titanium, manganese and other elements, and subsequent
transformation of high oxides into low on the slag-metal interface. Argon

graphite or varnish are good for Cooper and copper alloys as well as for
steel with high carbon content. The following protective measures should be
taken-. (1) Use of fluxes free of oxides which could be ieduced by elements
in the steel being remelted; (2) obligatory cleaning or pickling of the
surface of the consumable electrode; (3) if the steel to 'be remelted has a
low ox1dation resistance at high temperature, the entire electrode surface
must be protected by a coating, or remelting must be conducted in a chamber
fi-I'led with neutral gas and encompassing the entire electrode; (4) oxida-
tion of an electrode heated by 6lect-ric clarrent is to be prevenied by using
the shortest th-roat possible, i.e. the current carrier is to be moved closer
to the melting space; (5) protection of the slag bath by bl,)wing arFon or

TITLE: EvaDoration cooled ingot mold for the electroslag remelting
of metal
PERIODICAL: Avtomaticheskaya avarka, no. 1, 1962, 87-88
TEXT: The authoT describes a new type of ingot mold for the electrosla,~_ re-
melting of metals, using evaporation cooling (see Figure). Steam bubbles,
j,,ontinuously formed on the outer surface of the inner viall in the thin boundc~
ry layer of water, leave the 'wall and either float to the exposed surface of
the water or are ccndensed beforehand. As much more heat is absorbed during
steam-formation than during the heating of water, the mold requires very much
less water than conventional double-walled copper molds with an enclosed
water jacket or spray-cooled mol6s. The temperature of the inner wall is
thus maintained at about 1000C. A mold of this new design was made and
tested. Its internal diameter was 140 mm, its height 500 mm and the thick-
ness of its walls 6 mm. To prevent the inner wall from melting and becoming
fused to the ingot, low-carbon steel, whose melting point is higher than
copper, was used. As a result of the tests, the mold was found applicable
