High-frequency quenching machines for guide rails are widely used in the machining industry, and the energy consumption of this machine is very low, so high-frequency quenching of guide rails has always been very popular. Let's learn about the working principle and high-frequency quenching of guide rails with Kehua. Let's develop an introduction. High-frequency quenching of guide rail 1. High-frequency quenching of guide rail The guide rail quenching equipment refers to a heat treatment method that uses high-frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece to a certain depth, while the core basically maintains the structure and properties before treatment, so a combination of high strength, high wear resistance and high toughness can be obtained. And because it is local heating, it can significantly reduce quenching deformation and reduce energy consumption. It is precisely because of the above characteristics of induction quenching that it is widely used in the machining industry. Second, the development Now more and more industries use induction hardening equipment, more and more enter the induction hardening equipment industry, more and more brands enter the Chinese market, such as the famous enterprise Zhengzhou Gaoshi Electromagnetic Induction Heating Equipment Co., Ltd., is to focus on In the research and development of various series of induction hardening equipment and heating solutions for industrial applications, to provide the best products for global users, and to bring the advantages of induction technology to the world's leading manufacturers and service companies. In the early 1930s, the United States and the Soviet Union began to apply the induction heating method to surface quenching of parts. With the development of the industry, the induction heating heat treatment technology has been continuously improved, and the application scope has been continuously expanded. Third, the working principle The high-frequency quenching machine adopts induction heating. The principle of induction heating is: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube inputting intermediate frequency or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000ºC in a few seconds, while the temperature of the core rises very little. High-frequency quenching of guide rail Kehua has introduced the working principle and development of high-frequency quenching of guide rail for us.
