[0002] With the development of science and technology and the progress of the times, the development of steel castings is also very rapid. However, the quality of steel castings is currently greatly affected by the cooling rate, such as the wall thickness and internal structure of the casting. The thick wall dissipates heat faster than the thin wall because the thicker the wall is, the more energy it carries, and the heat dissipation is naturally slower. Secondly, the surface structure dissipates heat faster than the internal structure because the heat loss is radiated from the inside to the outside. Casting cooling is a process of contraction during thermal expansion and contraction. If one part of the casting shrinks faster and another part shrinks slower, the casting will be affected by internal stress, which will lead to deformation of the casting, casting defects, etc.
