During the solidification process of steel ingot, the flow pattern of the molten steel will have significant effect on the formation of solidification microstructure. In present study, the solidification microstructure of 30Cr2Ni4MoV steel ingot under different strength of mechanical vibration(forced-convection) was simulated using ProCAST®software. The results showed that the increase of the strength of vibration could restrain the development of the columnar grains and refine the gains. With the increase of the strength of vibration, the proportion of columnar grains decreased while the proportion of equiaxed grains increased and the effect of refining grains on columnar grains was better. When the strength of vibration was at a low level, the effect of refining grains can be improved obviously by increasing the strength. However，when the strength increased to a high level(0.833), the increase of the strength of vibration couldn’t make the effect of refining grain better.
