Abstract

An alloy for use in refining iron and steel and containing .Ca.32-50% .Si.50-68% .Fe.0-10% .Al.0- 5% is produced by smelting in an electric are furnace a charge consisting of .SiO2.30-55% .CaO.20-45% .Carbonaceous. .reducing agent.15-45% The reducing agent is at least 50% bituminous material; metallic aluminum and/or iron may be added to the tapping ladle if insufficient results from impurities in the charge. Before tapping, 0.001 to 10% of flux, based on the silica in the charge, is added, the flux consisting of one or more of fluorspar, granite or the oxides or halides of magnesium, alkali or alkaline earth metal halides. Calcium carbide may also be added.
