Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material’s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
Induction tempering is a low temperature heat treating process normally performed after the induction hardening process has completed in order to reach a desired hardness to toughness range. Induction tempering of steel uses low-frequency electrical induction coils to produce results parallel to furnace tempering applications that typically take hours.
Induction tempering equipment results quickly. Tempering of hardened steels is a function of both time and temperature. Induction tempering uses shorter heating times (usually only seconds) and higher temperature to produce results equivalent to furnace tempering treatments that often require hours. Induction tempering can be performed on all hardened components. The result is a component with increased toughness, ductility and impact strength.
