研究了二次冷却带电磁搅拌和冷却强度对高碳铬轴承钢连铸坯偏析的影响，并对“白亮带”及中心碳偏析的形成机理及其影响因素进行了较为系统的分析，提出了改善偏析的措施。试验结果表明，采用搅拌电流为１３０Ａ、搅拌方式为“左旋１０ｓ停７ｓ右旋１０ｓ”快频交替间歇式弱搅拌和适当的二冷制度（０．４Ｌ／ｋｇ左右），轴承钢坯的质量将得到明显的改善
The effects of secondary cooling zone electromagnetic stirring and cooling intensity on the segregation of high carbon chromium bearing steel continuous casting billet were studied. The formation mechanism of “white bright belt” and central carbon segregation and its influencing factors were systematically analyzed. Measures to improve segregation. The experimental results show that the quality of the bearing billet will be obtained by using a stirring current of 130 A and a stirring mode of “intermittent weak stirring with alternating frequency of 10 s for 7 s and right rotation 10 s” and an appropriate secondary cooling system (about 0.4 L / kg) Significant improvement
