With the continuous development of cryogenic treatment technology, cryogenic treatment equipment has gradually become a new type of equipment, but in the process of cryogenic treatment, the cryogenic process is the key to determining the treatment effect. How can we formulate an appropriate process? Under normal circumstances, how many aspects need to be started in the formulation of cryogenic treatment processes?

　　The cryogenic treatment process needs to start from the following aspects:

　　 1. Clarify the purpose of the test: What performance is required to improve is to improve dimensional accuracy or improve impact toughness? Is it to improve the hardness, wear resistance or other conductive properties? Different requirements determine different processes.

　　2, the material of the work piece: the difference of the material of the work piece determines its Mf point, and the temperature of the cryogenic treatment should be lower than its Mf point, so the temperature of the cryogenic treatment is related to the material of the work piece.

3. The size and geometric shape of the workpiece: The size of the workpiece determines the holding time of the workpiece, and the geometric shape determines whether the cryogenic treatment requires the previous process to eliminate the stress in advance. At the same time, the cooling speed is mainly determined by the geometric shape and the stress state of the workpiece. decided.

4. Cost to performance ratio: On the premise of meeting customer requirements, reduce costs as much as possible. Modern enterprises have a clear division of labor and have cost control requirements for each stage of the supply chain. As a manufacturing company, you should also consider deep Cost-effectiveness of cold treatment equipment. In terms of the effect of cryogenic treatment, of course, the lower the temperature, the better the effect. But considering the issue of cost, in actual production, everyone usually achieves a little lower than the Mf point.
