WHAT IS INDUCTION HEATING?
Electromagnetic induction heating, or induction heating for short, is a method of heating conductive materials such as metals. It is mainly used for metal thermal processing, heat treatment, welding and melting.
As the name suggests, induction heating uses electromagnetic induction to generate electric current inside the heated material, and relies on the energy of these eddy currents to achieve heating purposes. The basic components of an induction heating system include an induction coil, AC power supply and workpiece.
Depending on the heating object, the coil can be made into different shapes. The coil is connected to a power source, and the power source provides an alternating current to the coil. The alternating current flowing through the coil generates an alternating magnetic field that passes through the workpiece. This magnetic field causes the workpiece to generate eddy currents to heat the workpiece.
