摘要
介绍了连铸轻压下技术在某钢厂320 mm×425 mm连铸机GCr15轴承钢的应用.比对了两种不同的轻压下工艺与未实施轻压下工艺GCr15轴承钢低倍质量的差异.结果表明,实施轻压下工艺的轴承钢低倍质量,比未实施轻压下工艺的好.轻压下实施区域中心固相率为0.55~1.00的铸坯质量,比轻压下实施区域中心固相率为0.30~0.85的铸坯质量好.
The application of soft reduction on a bloom CCM is described. The comparison is on the macrostructure differences by two different soft reduction processes and the process without soft reduction for casting bearing steel GCr15. The results show that the macrostructure applied with the soft reduction is better than the one without the soft reduction. The macrostructure of soft reduction zone with solid phase ratio from 0. 55 to 1. 00 is better than the one with solid phase ratio from 0. 30 to 0. 85.
