Abstract

PURPOSE: To utilize the remaining Fe and CaC2 and to solve the probelms such as the generation of C2H2, etc. accompanying the disposal by throwing away, by using the slag generated when the molten pig iron or the molten steel has been desulfurized with CaC2, as a part of the raw materials for sintering the iron ore.
