Abstract

ABSTRACT The thermal and numerical simulation of the mould electromagnetic stirring (M-EMS) during continuous casting (CC) of the GCr15 bearing steel was performed. The thermal simulation apparatus with the M-EMS was used to examine the effect of stirring parameters on solidification structures. It was found that M-EMS enlarged the equiaxed grain regions, refined the grain size and resulted in more homogeneous distribution of the solute elements. The flow field in the mould was simulated to show the M-EMS intensity, which is in accordance with experimental observations. The mechanical properties of the blooms obtained at the current of 300A and frequency of 5 Hz are optimal.

GCr15轴承钢模具电磁搅拌热数值模拟

对GCr15轴承钢连铸过程中的结晶器电磁搅拌(M-EMS)进行了热模拟和数值模拟。利用M-EMS热模拟装置研究了搅拌参数对凝固组织的影响。结果表明，M-EMS扩大了等轴晶区，细化了晶粒尺寸，使溶质元素的分布更加均匀。模拟了结晶器内的流场，得到了M-EMS的强度，与实验结果一致。在电流为300A、频率为5hz的条件下得到的熔花的力学性能最佳。
