The principle of high frequency machine

Posted by Wangkiky Wangkiky over 6 months ago

The high frequency machine and induction heating technology have the highest heating efficiency, the fastest speed, and the low consumption and environmental protection. It has been widely used in the process of hot processing, heat treatment, heat assembly, welding and melting of metal materials in all walks of life. It can not only heating the whole piece, but also for the local heating of the workpiece; deep heating of the workpiece can be realized, can also be heated only on the surface, the surface of the metal material concentration; not only can direct heating, but also indirect heating of non metallic materials. Wait。 Therefore, the induction heating technology will be used more and more widely in all walks of life.[url=http://bestcoatingmachine.com/evaporation-coating/52.html]Car Logos PVD Vacuum Coating Machine[/url] A surface heat treatment process using induction current to heat the workpiece locally. This heat treatment process is often used for surface hardening, also for local annealing or tempering, and sometimes for overall quenching and tempering. In the early 1930s, the United States and the Soviet Union began to apply induction heating to the surface hardening of the parts. With the development of industry, the heat treatment technology of induction heating is constantly improved and its application scope is expanding.[url=https://vacuumfurnacetype.com/custom-furnace/169.html]Industrial Inert Gas Heat Treatment Furnace Price[/url] When the workpiece is placed in the inductor (coil), the alternating magnetic field is generated around the inductor when the alternating current of a certain frequency is entered. The electromagnetic induction of the alternating magnetic field causes a closed induction current in the workpiece - the eddy current. The distribution of the induced current on the section of the workpiece is very uneven, the surface current density of the workpiece is very high and gradually decreases inward. This phenomenon is called the skin effect. The electric energy of the high density current on the surface of the workpiece is transformed into heat energy, which makes the surface temperature rise, that is, the surface heating is realized. 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 is. The surface quenching can be achieved when the temperature of the heating layer exceeds the critical point temperature of the steel.[url=https://vacuumfurnacetype.com/buy-furnace/2125.html]Sintering Furnace Price[/url]
