1, the flow of high-frequency and high-frequency machine is made of circular or heating coil (usually with copper production) other shapes. Coil which produces changes in the magnetic polarity of the instantaneous beam will be heated metal objects placed inside the coil, the magnetic flux will be heated through the whole object of small high-frequency machine, the object being heated inside the heating current in the opposite direction , there will be corresponding large eddy currents. Because of the heated object memory in the resistance, it will have a lot of Joule heat, so that the rapid rise in body temperature itself. All metallic materials to achieve the purpose of heating. 2, in the high-frequency machine by a unique set of electronic circuits, external power input comes from 50Hz low-frequency alternating current into high frequency alternating above 20000Hz; after a high-frequency current to the coil, the principle of electromagnetic induction to convert into high-frequency magnetic field, and in a magnetic field acting on the metal object; eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal objects automatic high frequency machine, the current flowing in the metal objects, it will by means of internally inherent resistance value generated by the current thermal effect principle of heat, this heat is generated directly within the body, so the high-frequency machine, this heating method, fast and efficient. If desired, it may be any metal melt in an instant. Moreover, its heating rate and temperature are controlled. Principle of the workpiece into a high-frequency inductor (coil) inside, when the sensor is passed through a certain frequency alternating current, i.e., generates an alternating magnetic field around. Electromagnetic induction of the alternating magnetic field so that an induced current generated within a 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, a phenomenon known as the skin effect. High density current workpiece surface energy into heat energy, so that the surface temperature rises, i.e. to achieve surface heating. Current higher the frequency, the workpiece surface and internal current density difference is bigger, the heating layer thinner. Rapid cooling in the heating surface temperature above the critical point temperature of the steel after high-frequency machine supplier, you can achieve surface hardening.
