Heat treatment auxiliary process for metal material parts

The invention discloses a heat treatment auxiliary process for metal material parts. The heat treatment auxiliary process comprises a casting body, auxiliary casting test blocks, a tool main body box, a device main body mechanism and an auxiliary mechanism, the outer wall of the casting body is provided with a plurality of auxiliary casting test blocks, and the outer walls of the auxiliary casting test blocks are attached to the outer wall of the auxiliary mechanism through spot welding; and the device main body mechanism and the casting body are fixed in a spot welding mode. According to the technical scheme, the tool main body box is used for covering the auxiliary casting test block by using the box-shaped tool cover, the process principle of controlling the cooling speed of the auxiliary casting test block through the sizes of the ventilation holes in the tool main body box, checking the specific surface area of the casting body and determining the sizes and the number of the ventilation holes is feasible
