METHOD OF STEEL MAKING IN OXYGEN CONVERTER Russian patent published in 2001 - IPC

Abstract RU 2169197 C2

FIELD: ferrous metallurgy, particularly, methods of steel making in converters with use in iron charge of various metal scrap. SUBSTANCE: method includes charging of metal scrap, lime, pouring of pig iron, blowing of bath with gaseous oxidizer and charging of iron-containing product of processing of waste slags including metal component in amount of 60% an slag component in amount of 40%. Lime consumption is determined by expression given in the invention description. EFFECT: higher stability of converter lining, reduced consumption of lime and increased rate of slag formation. 2 ex
