FIELD: metallurgy.
SUBSTANCE: invention relates to production of steel in arc steel-making furnaces. Method of steel production in arc steel-making furnace includes supply of charge into furnace, melting, slag foaming by means of blowing with oxygen and blowing of carbon-containing material by injector at the end of melting period and in oxidation period. In the method, during the whole period of operation of the furnace under the foamed slag, the ratio of the height of the arc penetration into the slag and the metal to the length of the arc is maintained equal to 1.18–1.20.
EFFECT: reduction of specific power consumption and melting time with simultaneous increase of productivity.
