A split induction heating gradient heat treatment device

Abstract

The invention discloses a split inductive heating gradient heat treatment device which consists of a positioning base plate, a cooling tank and multiple independent inductive heating units, wherein each inductive heating unit consists of an independent power supply, a support base, positioning keys, a thermocouple and an arm type inductor; the positioning keys are arranged at the bottoms of the support bases of the inductive heating units, and are matched with sliding chutes of the positioning base plate; the inductive heating units move in the radial direction of the positioning base plate. According to the split inductive heating gradient heat treatment device, the independent inductive heating units are adopted for piecewise heating the disc edge of a disc-shaped part, and are removed respectively after gradient heat treatment is finished, and the disc-shaped part is directly quenched after being taken out, so that the working efficiency is high; the inductive heating units move in the radial direction of the positioning base plate to perform gradient heat treatment on disc-shaped parts with different diameters of 500 to 800mm, and the split inductive heating gradient heat treatment device is particularly suitable for heat treatment operation over large-sized disc-shaped parts.

Description

technical field [0001] The invention belongs to the field of metal heat treatment equipment, and in particular relates to a split-type induction heating gradient heat treatment device. Background technique [0002] Invention patent ZL201210125994.0 discloses "a resistance heating gradient heat treatment device for disc-shaped parts", see figure 1 , The resistance heating gradient heat treatment device is composed of two furnace bodies, an upper furnace body and a lower furnace body. The upper furnace body and the lower furnace body are equipped with independent cooling boxes, and the cooling boxes are filled with heat-conducting salt, cooling pipes are arranged, and the water flow rate through the cooling pipes is controlled by a hot water circulating pump. The edge of the disc is heated by radiation through the resistance band, and the core is fully cooled by the upper cooling box and the lower cooling box. The temperature gradient between the edge and the center is 300-50...
