Abstract

PURPOSE: To let desulfurization and dephosphorization be accomplished simultaneously by causing molten cast iron or steel to react with metal nitrides such as magnesium nitride and calcium nitride.
CONSTITUTION: In a ladle or the like, molten cast iron or steel is caused to react with metal nitrides such as magnesium nitride, calcium nitride or lime nitrogen. This reaction causes the phosphorus in the iron or steel to dissociate and be combined with magnesium and calcium. Or, sodium nitrate and the like are simultaneously added in combination and are oxidation-removed. This method improves desulfurization and dephosphorization efficiency.
