Abstract

Abstract: A new method for adjusting the starting point of the hardening layer produced by induction hardening was developed, which utilizes the eddy current generated by the copper material in the alternating magnetic field to form a reverse magnetic field to achieve the adjustment of the hardening layer starting point. The new method has a large adjustment range, and while adjusting the hardening layer starting point, it does not affect other heat treatment assessment indicators such as the depth of the hardening layer. It can realize online adjustment of the hardening layer starting point, convenient operation, and quick adjustment with high practical value in production.

Key words: induction hardening, hardening layer, starting point, induction coil
