Common problems in heat treatment process!

Hebei Yuantuo Mechanical and Electrical equipment Manufacturing Co., Ltd. is a strong Induction heat treatment furnace manufacturing unit, has nearly 20 years of induction heating equipment R & D and production experience. In Hebei Yuantuo electromechanical equipment manufacturing plant has been growing and growing, helping many customers to solve product problems. The following remote electro-mechanical knitting finishing some of the common problems in the process of heat treatment, let’s take a look!

1. During the heat treatment process, the heat convection is excessive or too small, or the heat is heated in the air or heated in an atmosphere, and the heat treatment process is affected, so that the heat treatment process is deformed.

2. In the cooling process, due to the different cooling speed of each section of the material, the temperature difference is formed in each section, so that the volume of each part of the material is contracted to be different, so that thermal stress is formed. In addition, during the quenching process, during the transformation of the super-cooled austenite of the material to the martensite transformation, the specific volume changes, so that the tissue stress is formed, and the phase change deformation is caused.

3. The chemical composition, raw material defect, original group, heating factor, cooling factor, etc. of the heat treatment process itself may cause the material to crack during the heat treatment process.
