Improving slag reaction with molten metal in indirectly-heated furnaces, e.g. induction furnaces, adds slagging materials in solid form before melting of charge is complete

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.
