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
