AOD AOD REFINING METHOD OF AUSTENITIC STAINLESS MOLTEN STEEL

摘要

According to an aspect of the present invention, there is provided a method of manufacturing an austenitic stainless steel comprising: preparing an austenitic stainless steel in an electric furnace; Adjusting the carbon concentration of the molten steel to 2.0 to 2.5 wt% and introducing the molten steel into an AOD (Argon Oxygen Decarburization) refining furnace; And injecting oxygen (O ₂ ) and argon (Ar) into the molten steel and decarburizing the molten steel; And a reducing-desulfurizing step of blowing argon (Ar) into the decarburized molten steel, to an AOD refining method of an austenitic stainless steel molten steel.
