Heat treatment is still very common. The material has to go through three processes of heating-insulation-cooling in the solid state, and then ensure that the structure and performance meet the expected requirements. In this way, the process of metal thermal processing is also guaranteed. So how does such processing take place? What kind of characteristics does it have? Chongqing Zhenzhan Heat Treatment Co., Ltd. analyzes for you:
Introduction to the process
The process of heat treatment is still very simple. Generally, there are heating, heat preservation and cooling processes. In some cases, heat preservation is not required, and direct heating and cooling can be used. Metal processing can be carried out according to the specific conditions of the material. There are many heating methods, generally charcoal and coal are used for heating, or gas fuel can be used. At the same time, it should be noted that when the metal is heated, the workpiece is exposed to the air, which is prone to oxidation and other problems, so special attention must be paid to protection.
Cooling is also an indispensable part of daily processing, and it is generally necessary to control the cooling speed. The cooling speed of returned goods is relatively slow, and the cooling speed of whole work is fast, and the quenching speed is faster. Cool down as needed.
Introduction to process classification
Metal heat treatment is also carried out, but the process will also have great differences, such as overall, surface and chemical heat treatment. Generally, the process selection should be carried out according to the heating medium, temperature and cooling method, so as to ensure a good processing effect.
