Hebei Yuantuo Mechanical and Electrical equipment Manufacturing Co., Ltd. is a powerful induction heat treatment equipment production unit in China, with nearly 20 years of experience in Metal heat treatment furnace research and development. In Hebei Yuantuo Mechanical and Electrical equipment Factory continues to grow and grow, to help many customers solve product problems. The following Yuantuo electromechanical small collation about the heat treatment process of some common problems, let’s take a look at it!
1, 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.
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.
In addition, the manufacturer of remote electromechanical intermediate frequency heating furnace should remind everyone that correct heat treatment processing operation (such as hole plugging, hole binding, mechanical fixation, suitable heating method, correct selection of cooling direction of die and movement direction in cooling medium, etc.) and reasonable tempering heat treatment processing technology are also effective measures to reduce the deformation of precision and complex die.
