increasing the velocity.of the gas-air mixture from the
dog house.to 100 to 120 m/sec. The pressure in the
gas vertical flue,increased,to the 'atmospheric pressure
and at maximum thermal loads to 10 mm H20- The
temperature of the upper checkers of,gas,regenerators
was maintained at 3.200 to JL250*C- The consumption of
oil remained the same as on firing with mixed gas.
,During the melting period, the flame was covering the
bath satisfactorily but-during the refining period at
low thermal loads the length .of the flame.was insufficient.
In this case, Ian improvement can be obtained by decreasing
the.coefficient of excess air to 0.9 to'l.O. Changes in
the operating indices of.the furnace on transfer.to
firing with hot.coke oven gas aregiven in tables 1 and 2.
The preliminary results.obtained indicated that,in
respect of productivity and fuel consumption,the
furnace operation was satisfactory. Further investigation

TITLE. Production:of Low.Alloy Steels 19G.and 14KhGS Without

PERIODICAL: Stall, 1960, Nr 3, pp.2167219 (USSR)
ABSTRACT: This is a~repbrt.concerning test melts conducted.by
the personnel of the Central Scientific Research Institute-
of Ferr,ous,Metallurgy.,(TsNIIChM):and, the Alchevskiy
Metallurgical Plant (Alchevskiy metallurgicheskiy zavod
in Voroshilovsk). Alseries-of test melts of , 14KhGS and
19G steels were made in the,furnaces with chromium
magnesite roofj,fired.by mixed gas.. The furnaces.worked,
on-scrap--,ore process with twostage drawing off of slag.
13.5 ton ingots-were produced by.bottom pouring; 14.5
ton ingotsby direct'pou.-qing. The reduction took place
in the,ladle. 'The,change'of chemical content oftested

the foliowing conclusions:.(l) The investigated-method
of reduction of steels 14KhGS:and.19G (without intro-.
ducing silicon~into the furnace) permits a noticeable
decrease in theconsumption of manganese-silicon and a~
decrease of,expenses for reducer., (2) With'the increase
