Abstract

PURPOSE: To carry out desulfurization and graphite spheroidizing of molten pig iron without generating a flash and white smoke by adding Mg to molten pig iron in a closed vessel under pressure and then adding the molten pig iron of higher Mg content than that required in the production of usual nodular graphite cast iron to untreated molten pig iron.
