Induction heating is a process used to heat metals thanks to an electromagnetic field generated by alternating currents circulating in a solenoid.
Faraday-Neumann’s law describes in a general way, the phenomenon. An alternating electromagnetic field induces an electromotive force, which generates induced currents that flow along a metal body, placed inside the magnetic field
These eddy currents dissipate energy in the form of heat, thanks to the Joule effect, and heat the body without having any physical contact.
The Solenoid is an Inductor coil and it is powered by a Medium or High Frequency Converter.
Power and frequency of generator and the geometry of inductor are designed according to the geometry of the metal body to be heated, temperature to be reached, heating time, type of metal, depth of treatment, etc. This has been taught to us by science.
SELIT srl designs and builds generators able of providing high power even at high frequency. Thanks to its technology, SELIT provides the right frequency generator for the most varied applications without having to compromise and perfectly meets the target.
