    Description

    WRR-220 WRR-142 WRR-143 WRR-221 WRR-222 B thermocouples

    Product introduction:

    WRR-220 WRR-142 WRR-143 WRR-221 WRR-222 B thermocouples, surface heat treatment process for locally heating a workpiece by using an induced current. This heat treatment process is often used for surface quenching, but also for local annealing or tempering, and sometimes for overall quenching and tempering. In the early 1930s, the United States and the Soviet Union began to apply induction heating to surface hardening of parts. With the development of industry, the technology of induction heating and heat treatment is constantly improved, and the scope of application is also expanding.
    Induction heating is currently the fastest heating method known to mankind. The traditional heating method is heat conduction, that is, a hot object transfers its own thermal energy to another object, while induction heating uses an alternating current in the induction coil A eddy current, or eddy current, is generated in the coil to move the electron holes in the magnetically permeable object in the coil to generate heat. Induction heating is a great revolution of traditional heating methods!
    Induction heating device consists of two parts, one is the AC power supply that provides energy, also called variable frequency power supply; the other is the induction coil that completes the electromagnetic induction energy conversion, called the induction furnace.
