摘要: 对GCr15轴承钢在电渣过程中施加电磁搅拌,分析电磁搅拌对电渣铸锭凝固组织和化学成分的影响。结果表明,电磁搅拌可以显著改善电渣铸锭凝固过程传热条件,减少GCr15电渣锭网状碳化物的形成。同时,由于电磁搅拌的作用,电渣锭的C、Cr等主要元素成分偏析指数稳定控制在1.03以下。当搅拌电流为50 A至200 A,频率为6Hz时,电渣锭中心无网状碳化物形成,碳偏析指数为1.02。

Abstract: Based on electromagnetic stirring (EMS) in the electroslag process fbr bearing steel GCrl5,the effects of EMS on the superalloy solidification structure and chemical composition are analyzed. The result is as follows: Electromagnetic electroslag can signiHcantly improve the heat transfer condition of ingot solidification process, reduce the formation of network carbide in steel GCrl5 ingot. At the same time, because of the effect of electromagnetic stirring, the segregation index of main elements such as C and Cr in the ingot is stable less than 1.03. When the stirring current is 50 A to 2(X) A, the frequency is 6Hz. , there is no net carbide in the center of the ingot, and the carbon segregation index is 1.02.
