Numerical Simulation of Electro-slag Remelting Process Solidification Structure of Cr-Co-Mo-Ni Bearing Steel

摘要：

　　The solidification microstructure and crystallization of Cr-Co-Mo-Ni bearing steel were simulated in solidification process based on CAFE methods in the electro-slag remelting process.The optimization of the intensity of cooling and molten pool temperature was simulated for Cr-Co-Mo-Ni bearing steel.The result shows that raising the cooling intensity to 7.5 m3/h and reducing the superheat temperature to 1600℃ can increase the grain nucleation number about 13.83%,and reduce the average columnar grain radius about 10.61%,to have a very good effect on refining the grains and get dense uniform solidification,which improve the homogeneity of the solidification structure,and reduce the performance differences of the materials.
