Beschreibung
Zusammenfassung:	ferrous metallurgy. SUBSTANCE: method involves charging iron ore materials and coke; blowing hot air and fuel additives into blowing tuyeres; charging lump schungite with carbon content of 20-36% together with coke into annular zone of furnace mouth arranged within area restricted with radii making 0.1 and 0.95 of furnace mouth radius. Method is used for smelting cast iron in blast furnaces equipped with charging devices. EFFECT: increased efficiency and reduced consumption of coke. 1 ex
