1, high-frequency and high-frequency current flow machine is made of circular or heating coil (usually with copper production) other shapes. Coil which produces instantaneous changes in the magnetic polarity of the beam will be heated metal objects placed online circle automatic high frequency machine equipment, magnetic flux will be heated through the entire object, the object being heated opposite the interior of the heating current The direction, there will be corresponding large eddy currents. Because of the heated object memory in the resistance, it will generate a lot of Joule heat, so the rapid rise in their body temperature. 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 alternating current of high frequency above 20000Hz; after a high-frequency current to the coil, using electromagnetic induction principle is converted into a high-frequency magnetic field and a magnetic field acting on the metal object is; eddy current effect, generates a magnetic field proportional to the intensity of the induced current in the metal objects, the current flows in the metal object when the high-frequency characteristics of machine equipment, will by means of internally inherent resistance value, the principle of thermal effect generated by the current heat, this heat is generated directly within the body, so the high-frequency machine equipment, this heating method, fast and efficient. If required, any metal material which can be melted in an instant. Moreover, it is the heating rate and temperature controlled. Use a high-frequency machine, heat treatment: partial or total metal hardening, annealing, tempering, diathermy; two, thermoforming: whole, local forging, hot forging, hot rolling; three, Welding: brazing metal products, all kinds of cutter blade, serrated blade welding, steel, copper welding, the same kind of dissimilar metal welding; four, metal smelting: gold, silver, copper, iron, aluminum and other metals (vacuum) melting, casting and evaporation coating; five, high-frequency heating machine for other applications: semiconductor crystal growth, heat with bottle sealing, heat sealing toothpaste, powder coating, metal and plastic implants. The device uses high-frequency machine _ _ high-frequency machine equipment provided by Qingdao days Run High Frequency High Frequency Electric Co., Ltd. Qingdao Tianrun.
