Method for improved slag reaction with metallic melts in indirect heating furnaces for enhanced cleaning of nonmetallic inclusion charges

摘要

Slagging materials are added in solid form to the metallic charge which is to be melted. Before complete melting, a solid composition is formed in the furnace. Alternatively, solid material for melting and solid slagging material are charged into the furnace. Blending can also take place over partly-melted metal in the furnace.
