METHOD FOR MANUFACTURING STEEL THROUGH SMELTING REDUCTION

摘要

A method for manufacturing molten steel wherein iron ore and coal are continuously supplied onto molten metal containing carbon of 1% or less while blowing oxygen gas is being introduced onto the molten metal through a lance. Simultaneously with this operation, stirring gas is being introduced into the molten metal at a rate of 0.05 to 0.5 Nm3 /min/ton of molten metal through a tuyere. The slag and the molten steel produced, is continuously or periodically discharged.
