ABSTRACT:
The invention provides a slag conditioner for use in electric arc steelmaking which comprises 30 to 80% by weight of alumina, 10 to 30% by weight of aluminium 5 to 40% by weight fluorspar and 0 to 20% by weight of alkali metal carbonate. The conditioner is added with lime to deoxidized steel suitably in an amount of from 5 to 15 Kg/tonne of steel to promote rapid reduction of the initial refining slag iron oxide content together with increased slag fluidity and a faster rate of lime dissolution to form a reactive slag.
