[0002] The casting heat treatment device is a device used to perform heat treatment on castings. During the casting process, the casting usually undergoes processes such as melting, solidification and cooling, but these processes may cause uneven organizational structure or residual stress inside the casting. In order to improve the mechanical properties, wear resistance, corrosion resistance and other properties of the casting, heat treatment is required.

[0003] When processing wear-resistant castings, existing heat treatment devices usually use heating furnaces to heat treat the castings. However, the method of heating the castings through heating furnaces often requires workers to move and handle the heated castings, and the surface temperature of the heated castings is very high, which can easily cause burns to the workers. In addition, the natural air cooling method often makes it difficult to efficiently dissipate the heat of the castings after heat treatment, which also greatly affects the heat treatment effect of the castings after heat treatment.

[0004] Therefore, in order to address the problem that when the above-mentioned heat treatment device is used to process wear-resistant castings, due to the poor safety of its heat treatment structure during use, it is difficult to efficiently dissipate the heat of the castings after heat treatment, and the heat treatment effect of the castings is not good, a wear-resistant casting heat treatment device is developed. By adding a lifting and adjusting structure, a separated upper and lower processing structure, a water-cooled heat dissipation structure and a resistance heating structure to the heat treatment device, the safety of the device during use can be greatly improved, the effect of heat treatment of castings can be improved, and the heat dissipation effect and efficiency of the device on castings can also be improved.
