Hebei Yuantuo Electromechanical Equipment Manufacturing Co., Ltd. is a strong production and manufacturing unit of induction heat treatment equipment in China, with nearly 20 years of experience in R&D and production of induction reheating machine. In Hebei Yuantuo electromechanical equipment manufacturer has been growing up and growing, it has helped many customers solve product problems. Below, the mechanical and electrical minor editor of Yuantuo organizes some common problems in the heat treatment process, let’s take a look!
First, in the process of heat treatment, too much or too little heat convolution, or heating in air or in atmosphere, will affect the heat treatment process, resulting in deformation.
Second, in the cooling process, due to the different cooling rate of each section of the material, the temperature difference is formed in each section, so that the volume shrinkage of each part of the material is different, so that the thermal stress is formed. In addition, in the process of quenching, the specific volume changes during the transformation from undercooled Austenite to martensite, which forms the microstructure stress and causes the transformation deformation.
Third, the chemical composition of heat treatment, raw material defects, original group, heating factors, cooling factors and so on may cause cracks in the process of heat treatment.
