Melting - Of all types of metals. Other applications include crystal growing, cap sealing, sintering, carbon vapor deposition, levitation, exitaxial deposition, and plasma generation. Induction heating occurs due to the magnetic quality and resistivity of the material. The magnetic qualities are only present in magnetic steel. The varying electric magnetic field induces a current inside the component being heated in a similar way to that of a transformer.
Induction heating is a non-contact method.
The heat is generated only in the part, not in the surrounding area except by radiation. The location of the heating can be defined to a specified area on the metal component and achieves accurate and consistent results. As heating occurs in the object itself, induction heating is considered more efficient than alternative methods. An induction heating system comprises a basic induction power source which provides the required power output at the required power frequency, complete with matching components, an induction coil assembly, a method of material handling, and some method of water cooling. Most induction heating systems are water cooled with the exception of small, low powered units.
