Ultra high frequency induction heating equipment is mostly used for the industrial metal parts surface quenching. It is a metal heat treatment method that produces a certain induction current on the workpiece surface, rapidly heats the surface of the part at high frequency, and then rapidly quenching. Super audio induction heating equipment, that is, induction heating the workpiece, to carry out the surface hardening equipment.

The principle of ultra high frequency induction heating equipment: the workpiece is placed into an induction coil, which is a generally a hollow copper pipe with the input of medium frequency or high frequency AC. Produce alternating magnetic field in the workpiece to produce the same frequency induction current, the distribution of the induction current in the workpiece is not uniform, strong on the surface, and in the interior is very weak, close to the core, using the skin effect, can make the workpiece surface heating rapidly, in a few seconds the surface temperature rises to 800- degree, while the workpiece core temperature increases very little.
