【摘要】 降低钢水氧含量对于轴承钢的冶炼是非常重要的。本文通过转炉生产轴承钢的实践,对冶炼各环节钢中氧含量进行分析,找到钢中氧含量的影响因素。结果表明,为了降低钢中氧含量,控制转炉下渣量、改善LF和VD炉的造渣条件是非常关键的。基于上述分析,提出转炉冶炼轴承钢降低钢中氧含量的措施,为生产优质的轴承钢创造条件。更多还原

【Abstract】 It is very important to reduce oxygen content of steel for smelting bearing steel. The oxygen content of steel in the process of steelmaking is analyzed. And the influence factor of oxygen content of steel is found by the practice of BOF smelting GCr15 bearing steel. The results show that in order to reduce oxygen content of steel it is key to control roughing slag amount and to improve flux condition of LF and VD. Based on above analysis the methods of reducing oxygen content of bearing steel are brought forth. It produces condition for producing high quality bearing steel.更多还原
