A process for steel production in eaf involving lancing slag as partial substitute to scrap in charge mix.

摘要

The present invention relates to a process for producing steel in electric arc furnace using lancing slag which is a solid waste as cost effective substitute to steel scrap. More particularly, the present invention is directed to a process for steel production in electric arc furnace using lancing slag generated during oxy-cutting of scrap, as partial substitution of steel scrap in charge mix. The present invention thus favour usage of lancing slag which contains about 70-83% FeO as partial substitute to scrap for cost effective production of steel through EAF, whereby for average 5.5 tons addition of lancing slag, the average metallic recovery is achieved to the tune of 2.35 tons, with effective de-phosphorisation, without increase in lime addition and without any increase in power consumption.
