ABSTRACT:
A method of dephosphorization and desulfurization for molten iron alloy containing chromium, which adds to the bath of molten iron alloy flux comprising alkaline-earth metal oxide and alkaline-earth halide and further adds to the same the predetermined quantity of oxidizing agent, so that simple, highly efficient and economical dephosphorization and desulfurization are performable to produce high-chromium steel or stainless steel of high quality, iron oxide, chromium oxide or oxidizing gas are used as the oxidizing agent.
