The heat treatment process should be analyzed in detail to better control its process nodes and make products that customers trust. Process refinement is node control, which is nothing more than the five factors we often say, namely human, machine, material, method, and environment.

It is necessary to know the state of the workpiece before heat treatment, to understand the state of the material, such as the processing state, whether there is any defect, bump, whether there is oxidation, as well as the state of forging and raw materials, etc., and a chemical composition statement should be provided if necessary. By checking the appearance, shape, and relevant useful dimensions of the workpiece, it is convenient for the technicians to adopt effective methods, suitable processes, and suitable equipment to reduce heat treatment distortion and avoid early heat treatment failure. The parameters of the raw and auxiliary materials used in the production process must conform to the process specifications. Parts to be heat treated, defective parts and qualified parts should be placed in a fixed area and clearly marked to prevent mixing and wrong materials. The planning process of each area should also be in line with the process trend process, and the ineffective handling and ineffective waiting time in the process of the process should be reduced as much as possible, and the waste of manpower should be reduced.

The heat treatment is in a high-temperature working environment. Generally, the size of the workshop, cooling, noise reduction, and illumination must be considered. These factors directly affect the quality of the heat treatment. The heat treatment workshop must have a certain height and span, so that ventilation and process time can be ensured, and a lot of oil fume, steam, etc. may be generated during heat treatment. As long as the space is reasonable, the rationality of operation can be ensured to a certain extent to avoid misoperation by employees and personal injury.
