What is induction heating?
Induction heating is a fast, efficient, precise, repeatable, non-contact method for heating metals or other electrically-conductive materials . An induction heating system includes an induction power supply which converts line power to an alternating current, delivers it to a workhead and work coil creating an electromagnetic field within the coil. The work piece is placed in the coil where this field induces a current in the work piece, which generates heat in the work piece. The coil, which is water-cooled and cool to the touch, is placed around or adjacent to the work piece. It does not touch the work piece, and the heat is only generated by the induced current flowing in the work piece.Induction heating is used in processes where temperatures are as low as 100 oC (212 °F) and as high as 3000 °C (5432 °F). It can be used in brief heating processes that are on for less than half a second and in heating processes that are on for months.
Induction heating is used in domestic and commercial cooking, and in many applications such as melting, heat treating, preheating for welding, brazing, soldering, curing, sealing, shrink fitting in industry, and in research and development.
