摘要
宣钢通过转炉双渣、高拉碳操作，控制终点（≥O．15％c，≤O．OO10％Ti），LF采用高碱度渣系精炼，连铸控制合理的过热度、拉速，生产的GCrl5轴承钢氧含量达到0．0008-4）．0012％，氮含量0．0037--0．0050％，钛含量平均O．0026％，质量达到GB／T18254标准要求。
The GCrlSbearing steel is produced by Xuan Steel through the double slag process and catch carbon practice, the control of the blowing end（ 〉 0.15%C, 〈 0.001 0%Ti） in converter, the use of high basicity slags in LF refining, the reasonable control of superheat and the casting speed in continuous casting. The oxygen content of GCrl5 bearing steel is 0.0008%-0.0012%, nitrogen content is 0.0037%-0.005%, and the average titanium content is 0.0026%, the quality of the GCr15 bearing steels reaches the technical requirements of the GB/T18254 standard.
