Induction heating heat treatment
Inductive heating is a non-contact heating process used to heat ferromagnetic materials such as steel and iron. In this process, an alternating current flowing through a coil creates an oscillating magnetic field, which induces eddy currents in the material being heated. This phenomenon, known as ......
