Designing of suitable construction of high-frequency induction heating coil by using finite element method

摘要

This paper describes 3-d modeling of an induction heating system. To realize the suitable construction of high-frequency induction heating coil, numerical computations of eddy currents and heat conduction have been carried out by using the finite element method and also taking into account the dependence of material properties on temperature. Several modifications such as; spacing in between coil turns, motion of workpiece relative to the coil, and dimensional parameters were carried out until optimal design was achieved.
