对大冶钢厂连铸大断面轴承钢GCr15工艺进行了一系列的试验。试验表明,控制过热度在15- 20℃、拉速0．3-0．4m／min,采用合适的二冷制度和电磁搅拌技术,生产出的轴承钢连铸材质量完全满足GB18254的要求。
A series of experiments have been carried out on the GCr15 process of large-area continuous casting bearing steel in Daye Steel Mill. Experiments show that the control of superheat at 15-20 ℃, the pull speed 0.3-0.4m / min, the use of appropriate secondary cooling system and electromagnetic stirring technology to produce the quality of bearing steel continuous casting material to fully meet the requirements of GB18254.
