Summary of authoritative technical knowledge of medium frequency induction heating equipment

As long as it is professional and authoritative knowledge, we all want to know it, and read them carefully. There are too many technical designs in this industry. A comprehensive summary of the technical knowledge of intermediate frequency induction heating equipment will make you no longer confused.

Medium frequency induction heating technology is currently a technology with high heating efficiency, fast speed, low consumption and environmental protection for metal materials. It has been widely used in thermal processing, heat treatment, thermal assembly, welding and smelting of metal materials in various industries. It can not only heat the workpiece as a whole, but also heat the parts of the workpiece in a targeted manner. It can realize deep heat penetration of the workpiece, or only concentrate on its surface and surface. It can not only directly heat metal materials, but also heat non-metallic materials through holes. Materials are heated indirectly. Therefore, induction heating technology will be more and more widely used in all walks of life. With the development of industry, the processing technology of induction heating equipment has been continuously improved, and the application has been continuously expanded. A surface heat treatment process that uses an induced current to locally heat the workpiece. This heat treatment process is often used for surface quenching, and can also be used for local annealing or tempering, and sometimes for overall quenching or tempering.

Basic principle of medium frequency induction heating equipment

Put the workpiece into the inductor, and when an alternating current of a certain frequency is passed through the inductor, an alternating magnetic field will be generated around it. The electromagnetic induction effect of the alternating magnetic field causes a closed induced current-eddy current to be generated in the workpiece. The distribution of induced current on the cross-section of the workpiece is very uneven, and the electromagnetic density on the surface of the workpiece is very high, which gradually decreases inward. This phenomenon is called the skin effect. The electrical energy of the high-density current on the surface of the workpiece is converted into heat energy, which increases the temperature of the surface, that is, surface heating. The higher the current frequency, the greater the current density difference between the surface and the interior of the workpiece, and the thinner the heating layer。
