The principle of Ultra high frequency induction heating machine

  The workpiece is placed in the sensor, which is usually a hollow copper tube that is input medium frequency or high-frequency alternating current (1000-30000Hz or higher). The resulting altermuta magnetic field in the workpiece produces the same frequency of the sensing current, this sensing current in the workpiece is uneven distribution, strong on the surface, and is very weak inside, to the heart close to 0, the use of this skin-collecting effect can make the surface of the workpiece heating rapidly, in a few seconds the surface temperature rises to 800-1000 sordm;C, and the heart temperature rise is very small.
