METHOD FOR MELTING OXIDIZED RAW MATERIALS OF FERROUS METALS IN FURNACE WITH LIQUID BATH Russian patent published in 1996 - IPC

Abstract SU 1706216 A1

FIELD: ferrous metallurgy; applicable in blowing-in of furnace with liquid bath and bringing the furnace to stable operating conditions. SUBSTANCE: simultaneous charging of carbon reducing agent and ore is started after charging of only carbon reducing agent into slag layer to attain its volumetric concentration in slag layer of 5-50%. In accumulation of carbon, the slag bath is bubbled with oxygen-containing or inert gas, or with products of combustion of natural gas and/or liquid hydrocarbons. EFFECT: higher productivity and reduced consumption of carbon reducing agent due to reduced duration of blowing-in. 2 cl, 1 dwg, 2 tbl
