ABSTRAC.T.- 'An investigation is made of the effect of temperature and.,
baking rate on the properties of self -baking electrodes (E). The
electrode paste consisted 50016 of carbonized anthracite. coal and
50% of foundry coke, - with 24% pitch added thereto. It is estab-
lished that'in increase in firing temperature from 400 to,9000C
results in a decline. from 350 to Z67 kg/cmZ in the ultimate
strength.of the specimens while the true sp. gr. rose from 1.87,
to@ 1.9 1, apparent@sp. gr. diminished from 1.5Z to: 1.54, porosity
increased from 18.7 to Z3.87o, oxidizability declined-from. 16.04
to 13.397o, and friability increased from 4.03 to 9.416-.1-The re-
sistivity of the @ specimens, dropped sharply as baking temperamo
Card 1/2 ture rose from 400 to 7000C and then remained virtually stable

Silical reduction df2ring melting of ferroailicon and crystalline silicon involves
formation of intermediate oxide,.(the monoxide). Thermodynamic analysis of process
indicates that main reducer of silica is carbon, as reactioO with silica and silicon

TEXT: The carbide formation prooesse.4i during the melting of crystalline
silicon, farrosilicon, silicoohrome, silioonianganese and silicoaalaium has been
studied on pieces taken from different zones in the furnace.. The pieces were
,studied by chemical, petrographio, and mineralogic analysis. It has been proven
by such analysis and laboratory experiments that not only silicon oxide but
also silicon oarbide form side products. Silicon carbide was present In most
of the specimen parts, beginning with the top and ending with the bottom levels
in the furnaces, alorSwith'a great quantity of complex minerals. It was preaent
in amorphous form as well as In ole&,r oubio,and pollheiral crystals.. Various
impurities in it (Al. Fe, Or. Mn, C ound other) colored it yellow, green, blue,
blueish black. It was stated that the magma (of which the majority of the aamp-
les consisted) in oontaot with coke as well as coke impregnated with it had a

with liquid magma. It resembled very much the "ailoxiaon" described by N.Ye
Filonenko (Ref. 13: Issledovaniye fazovogo sostava. vozvratnvkh materialov'v

furnaaes. The article includes ptotmiorographs. Silicon carbide with an extra-
ordinarily dense structure was found in transfer products from a furnaoe malting
silicocalcium; it.may be assumed that it orystallized from the liquid state,
although any authors thought until r6oantly that silicon carbide does not exist
in liquid state. The greenish bloom on the inside of the graphite crucibles and
graphite rods in the quartz glass melting process in induction vacuum furnaces
was revealed to be fine crystalline SiC, and the crystals had also a blue and
yellow color, and sometimes these were till present In'ons crystal. Minute si-
licon nuggets were also-present in the bloom. It was concluded that silicon
carbide may form in reactions:

of the steelmaking process. These reports deal with problems of the
mechanism and kinetics of reactions taking place In t@e molten metal
in steelmaking furnaces. The following are also discussed: problems
involved in the production of alloyed. steel, the structure of the ingot,
the mechanism of solidification. and the converter steelmaking

TEXT: Vacuum treatment of Fe-Cr in the ladle makes it possible- to obtain
ingots with lowered (by,,/35%) oxide-impurity content. Under vacuuming of the
Fe-Cr its purification from-suspended oxide impurities is furthered by,tbe more
intensive liberation of gases and the consequent stirring of the alloy, which
occur at a residual pressure of 250 - 100 mm of mercury. The.oxide impurities
are borne out into the slag by the-rising streams of the alloy and by adhering
to the up-floating gas bubbles. The holding of Fe-Cr under vacuum beyond the
point at which the noticeable liberation of gas bubbles from it stops, has no ef-
fect upon the further purification of the alloy of oxide impurities. The degree
of purification of the Fe-Cr of oxide impurities depends chiefly upon their con-

tent In the state of suspension during the time of vacuumIng, and the higher 13
-the Si concentration and the lower the temperature of the Fs-Cr, the more oxide
Impurities are contained in the alloy in the state of suspension before the
vacuuming, and the higher the degree of purification from them of the Fe-Cr
during the vacuuming period. As result of the vetcuum. treatment the Fe.Cr is ob-
-tained with a lowered Si and gas content. Under crystallization of the ingots
made of this Fe-Cr. less oxide impurities are formed in them and the oxidation-
gas cavities present in ordinary FO-Cr Ingots, which are an additional-source of
oxide contamination of these Ingots, are absent. There are 6 references.

Abstract The necessity for@fuel saving gives new importance to
the method of processing coal - I.e. using heat treat-
ment for extraction of gas liquid tar and other by-
ji
products before combustion. The results of theoreti-
cal and experimental study are reported., The process.
-of separating gasand tar is,explained graphically
and in deta .il. 'The thermal.treatment of peat shale.
and pulverized coa'l'fro',m the Moscow basin is pre-,
sented with curves. The authori-recommend more re-!
search and consid er the reported study as the,begin-
-nirig of a new field in efficient fuel utilization
