摘要
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）。
Influence of electromagnetic stirring(EMS)in second cooling zone on carbon segregation of highcarbon chromium bearing steel billets has been investigatedThe mechanism of white band formation,central carbon segregation and their effect are discussed in detail in this paperThe test results show that the quality of bearing steel billets can be dramatically improved with following parameters:EMS current:130 A,EMS pattern is:in one direction 10 s,stop for 7 s,in another direction 10 s,and second cooling water consumption:about 04 L/kg
