摘　　要：本文根据冶炼轴承钢各工序特点,对转炉、精炼、真空、连铸过程铝含量控制进行试验研究。通过高拉碳、出钢控制下渣量、精炼过程控制碱度、连铸过程保护浇铸等措施控制过程铝波动,可有效控制轴承钢产品的氧含量和夹杂物水平,提高产品性能指标。According to the characteristics in each process of bearing steel smelting,the controlling methods ofaluminum content in converter, refining, vacuum and continuous casting were experimental researched. By high tapping carbon content, controlling slag quantity into ladle, alkalinity controlling in refining, protecting casting and othermeasures,fluctuation of aluminum content was controlled efficiently, so the good level of oxygen content and inclusionin bearing steel could be achieved,and the performance indicators were improved.

关 键 词：轴承钢 铝含量 氧含量 夹杂物
