induction heating service,induction heater,induction heating equipment and induction heating system are supplied by DaWei Induction Heating Machine Co.,Ltd
Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material¨s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
Induction Heating System
In a basic induction heating setup, a solid state RF power supply sends an AC current through a copper coil, and the part to be heated is placed inside the coil. When a metal part is placed within the coil and enters the magnetic field, circulating eddy currents are induced within the part. These currents flow against the electrical resistivity of the metal, generating precisely localized heat.
A basic induction heating system includes the power supply and induction coil. Some type of cooling mechanism is also required to remove waste heat from the system. Normally a water chiller or heat exchanger is used, but some power supplies utilize forced air cooling.
Power supplies and complete turnkey induction systems are available from a wide variety of manufacturers at various power levels. Small 1-2kW models effectively heat small parts; larger parts generally require more power, which increases the size, weight and cost. The power supply's operating frequency can range from 3kHz to 60MHz; Low frequencies in the 3 to 50kHz range are most effective for heating larger parts which require deep heat penetration. Relatively higher frequencies, up to 450 kHz, are more effective for smaller parts.
