发明名称 METHOD FOR PRODUCING NIOBIUM-ADDED STAINLESS STEEL
摘要 PURPOSE: A manufacturing method of stainless steel including niobium is provided to prevent clogging of an immerged nozzle in continuous casting and oxide inclusion in a coil surface by changing aluminum oxide to low-melting point inclusion. CONSTITUTION: A manufacturing method of stainless steel including niobium comprises the steps of: putting in Fe-Nb of 1~10kg/ton-steel, performing argon gas bubbling for 13~60 minutes with slag of 10~50kg/ton-steel, putting in iron alloy in the final casting ladle process, and putting in calcium of 0.01~0.2kg/kg-FeNb.
