CONVERTER METAL BLOW METHOD Russian patent published in 1995 - IPC

Abstract SU 1568525 A1

FIELD: ferrous metallurgy. SUBSTANCE: during metal blowing in converter, that provides for gas-shaped oxidizer, for example oxygen, feeding from top through form, termination of oxidizer feeding, inert gas blowing in during 15 - 20 s, before oxygen lance removal from converter after inert gas blowing in they exercise natural gas feeding with intensity of consumption of 2.0 - 3.5 m3/min·t during 0.2 - 1.0 minutes. In the case, inert and natural gas feeding is exercised in series through oxygen lance. EFFECT: increased converter lining durability. 1 tbl
