According to the characteristics in each process of bearing steel smelting,the controlling methods of aluminum content in converter, refining, vacuum and continuous casting were experimental researched. By high tap?ping carbon content, controlling slag quantity into ladle, alkalinity controlling in refining, protecting casting and other measures,fluctuation of aluminum content was controlled efficiently, so the good level of oxygen content and inclusion in bearing steel could be achieved,and the performance indicators were improved.
