METHOD OF STEEL MAKING IN ARC-TYPE FURNACES

摘要

FIELD: metallurgy. ^ SUBSTANCE: method involves supply of charge, melting, oxygen blowing, addition of lime with content of active lime of not less than 85% and coke during melting process and oxygen blowing. Lime with content of active lime of 40-70% together with metal junk is added to the furnace to the charge. Coke with particles with size of 5-40 mm is added during melting process and blowing process. Coke with particles with size of 0-3 mm is added after melting process is finished. ^ EFFECT: reduction of duration of melting process and electric power consumption. ^ 1 tbl
