What is a solid-state induction heating machine？
Solid state induction heating machine is a device that uses the induced electromotive force generated by high-frequency current in a conductor to cause the conductor to heat up. This heating method is mainly used for heating and heat treatment of metal materials, as it has the advantages of fast heating speed, high temperature control accuracy, and high heating efficiency.
Specifically, the working principle of a solid-state induction heating machine is to generate high-frequency current through a high-frequency power supply, which passes through a transformer and then generates an alternating magnetic field through an induction coil (usually made of copper or ferrite material). When the workpiece is placed in this alternating magnetic field, eddy currents are generated inside the workpiece due to electromagnetic induction, which are then converted into heat, thereby heating the workpiece. By adjusting the frequency and output power of the high-frequenc

How to select a suitable solid state induction heating machine?
Solid state induction heating machines, according to different output frequency levels can be divided into medium frequency, high frequency, and ultrahigh frequency induction heating machines. Also different induction heating process requests also need different frequency ranges. If choosing the wrong frequency level can not meet the induction heating requests, and cause the failed induction heat treating result.

-
- Induction hot forging: the bigger the workpiece diameter, the lower frequency should be.
- Induction heat treating: the lower the hardening depth, the high the frequency level should be. The bigger the hardening depth, the lower should frequency should be chosen.
- Induction brazing: The larger the brazing area, the lower frequency should be.
- Induction melting: We choose the suitable induction melting furnace as per the production efficiency, smaller volume can choose high frequency induction machine, and bigger volume can choose medium frequency induction machines.
