Optimized regime of induction heating of a disk before its pressing on shaft

Abstract

The paper deals with induction heating of a metal disk before its pressing on a shaft with the aim to find the optimum parameters of its regime. The velocity and efficiency of the process is affected by the arrangement of the inductor, its position with respect to the heated disk, orientation of its windings, amplitude and frequency of the field current and material of the disk that may be ferromagnetic or nonmagnetic. The task is formulated as a weakly coupled problem. The computations are mostly carried out by the FEM-based professional programs OPERA and QuickField supplemented by special user procedures.
