Abstract
FIELD: ferrous metallurgy, melting of naturally alloyed iron-carbon steels and alloys in hearth furnaces, particularly, in open-hearth and electric furnaces. SUBSTANCE: in melting naturally alloyed steels and alloys, charged onto pad of charge materials in zones of the slowest melting of charge is carburetor in combination with materials contain compounds and/or alloys reducing and alloying elements which are covered with lime and/or limestone is separated from carburetor and materials containing reducing and alloying elements. Prolonged residence of easily oxidized alloying elements in contact with carburetor in reducing zone allows preservation of freshly reduced alloying elements in meal melt, removing of slag of the first period during the cold period without loss of these elements. EFFECT: reduced cost of steel production provision for operation on fresh charge, utilized ores and production wastes containing oxidized and reduced alloying elements.
