[0002] Metal heat treatment is a process of heating, keeping warm and cooling a metal workpiece in a certain medium, and controlling its performance by changing the surface or internal structure of the metal material. Metal heat treatment processes can be roughly divided into three categories: overall heat treatment, surface heat treatment and chemical heat treatment. Depending on the heating medium, heating temperature and cooling method, each category can be divided into several different heat treatment processes. The same metal can obtain different organizations and thus have different properties by using different heat treatment processes. Steel is the most widely used metal in industry, and the microstructure of steel is also the most complex, so there are many types of steel heat treatment processes.

Heating of different types of metal parts requires multiple devices for processing, resulting in high production costs. Therefore, a metal surface heat treatment device is proposed to solve the above problems.
