The invention discloses an inductor for simultaneous induction heating and quenching of double-step flanges. Along the circumferential direction of the induction coil, the inductor divides the entire induction coil into five parts, and the adjacent parts are connected by steps, so that the whole The coil is composed of five parts with different heights, and each part is provided with several magnetizers, so that for the double-step flange, the inductor can simultaneously heat two flange cylinders with different heights and different diameters. Parts can realize induction heating and quenching once, which can reduce a second induction heating and quenching process, double the production efficiency, and reduce the labor intensity of producers by 50%.
Description
【Technical field】 [0001] The invention belongs to the field of inductors for induction heating and quenching, in particular to an inductor for simultaneous induction heating and quenching of double-step flanges. 【Background technique】 [0002] For induction heating and quenching of double-step flanges, in order to avoid quenching and cracking at the sharp corners of the steps due to the sharp corner effect, induction heating needs to avoid the sharp corners of the steps, and ensure that the depth of hardened layers of outer circles with different diameters meets the design requirements. The traditional induction heating of stepped parts can be roughly divided into two methods: using different diameter heating coils to carry out continuous or simultaneous induction heating and quenching on the double-step flange in two steps, that is, induction heating and quenching for one step first, and then Induction heating and quenching of another step can meet the technical requirement...
