Semi-solid M2 steel casting ingots were prepared using inclined slope pre-crystallizationmethod, and the microstructure at different slope length and thermal plasticity of ingots wereinvestigated in this paper. It was clarified that semi-solid processing technology can solve theserious problem of eutectic carbides segregation in casting microstructure. The dendritic primaryaustenite grains are changed into non-dentritic or equiaxed grains, and the eutectic ledeburitecarbide networks are fine. So, it improves the thermal plasticity of casting ingots, and the carbidedistribution of the semi-solid casting ingots is better than conventional casting after being forged
