ABSTRACT:
A molten iron and steel is refined by feeding a compressed and deformed composite clad obtained by clading a core material of at least one of metallic calcium, metallic magnesium, calcium base alloys and magnesium base alloys with a sheath of iron, into the molten iron and steel at a feeding rate of 20-500 m/min. while deoxidizing, desulfurizing and spherodizing of graphite are effectively carried out.
