High frequency machine is currently the most efficient metal material is heated, the fastest, low energy and environment-friendly induction heating equipment. High frequency machine full name of "high frequency induction heating machine", also known as high-frequency heating machine, high frequency induction heating equipment, high frequency induction heating equipment, high frequency heating power, high frequency power, high frequency welding machines, high frequency induction heating machine, High-frequency induction heaters (welding), and other high-frequency heat sealing machine, in addition to induction heating equipment, ultra-high frequency induction heating equipment. Wide range of applications. High Frequency machine is referred to all the high-frequency devices, one is heated metallic material, and the other is heated non-metallic materials. Uses can be used pure or contain any special purpose PVC soft and hard film welding machine accessories, leather or fabric of the more than 30% PVC can be processed. Principle of the workpiece into a high-frequency inductor (coil) inside, when the sensor is passed through an alternating current of a predetermined frequency, i.e. around the alternating magnetic field. Electromagnetic induction of the alternating magnetic field of the induction currents generated in the closed workpiece - vortex. Induced current distribution in the cross section of the workpiece is not uniform, the workpiece surface is very high current density gradually decreases inwardly, this phenomenon is called the skin effect. Workpiece surface high density currents of electricity into heat, so that the surface temperature rises Qingdao high-frequency heat sealing machine, namely to achieve surface heating. The higher the current frequency welding machine supply, the workpiece surface and internal current density difference is greater the heating layer thinner. Rapid cooling in the heating layer temperature exceeds the critical temperature of the steel post, you can achieve surface hardening.
