Casting cracks tended to significantly reduce the reliability of the casting, shorten the service life of the casting in the process of coal production, so it is of great significance to find the cause of the castings crack formation, and effectively prevent the formation of the crack in the coal production. The hot crack and cold crack of casting were introduced in detail, and the characteristics, formation process and influence factors were analyzed, which aimed at preventing casting crack formation, and fully ensure the normal operation of the casting.
