Abstract：By taking a series of measures such as controlling inclusion source, optimizing deoxidization technology, using high basicity refining slag, modifying the inclusions, improving soft blowing process and protective casting, Xiwang Special Steel achieved smelting of ultra low oxygen bearing steel. Total oxygen content T[O]≤8×10-6,B-type inclusion (Heavy) level 0-0.5, (Thin) level 0-1.0, D-type inclusion (Heavy) level 0-0.5, (Thin) level 0-0.5.
