METHOD FOR REFINING THE STAINLESS STEEL

摘要

The present invention relates to a method for refining stainless steel, comprising: the decarbonizing step of reducing carbon in molten steel in a reducing furnace; the deoxidizing step of reducing an oxide in the decarbonized molten steel by using a deoxidation material; the dentrifying step of reducing a content of nitrogen (N_2) in the molten steel before the end of the deoxidizing step; the sample collecting step of collecting a sample of the dentrified molten steel; and the nitrifying step of blowing nitrogen (N_2) to the molten steel after the sample collecting step.
