A Brief Review on Induction heating

Rekha Rana

Abstract

Induction heating is the method of heating an electrically conducting material (usually a metal) by electromagnetic induction, through eddy currents generating heat in the object. An induction heater is an electromagnet and an electronic oscillator that passes through the electromagnet through a high-frequency alternating current (AC). The rapidly alternating magnetic field penetrates the artifact, producing the conductor's electrical currents called eddy currents. The eddy currents flow through Joule heating through the resistance of the material. Heat can also be produced by losses of magnetic hysteresis in ferromagnetic (and ferrimagnetic) materials such as steel. The frequency of the current used depends on the size of the object, the type of material, the coupling (between the coil and the heating element) and the depth of the penetration. An important feature of the induction heating process is that the heat is produced within the object itself rather than through an external heat source by heat conduction. This allows objects to be heated very quickly. However, no external communication is required, which can be critical if contamination is a problem. Induction heating is used in many industrial processes, such as heat treatment in metallurgy, Czochralski crystal growth and semi-conductor grinding and refractory metals melting that requires very high temperatures.
