A heating furnace for heat treatment of wear-resistant parts

Abstract

The invention relates to the technical field of heat treatment equipment for wear-resistant parts, and provides a heating furnace for heat-treatment of wear-resistant parts, which aims to solve the problem that when the traditional heat-treatment heating furnace is heated, the temperature in the furnace body will be unbalanced, and the heat-treated wear-resistant parts will be unbalanced. It may cause the wear-resistant workpiece to be unable to effectively eliminate stress during heat treatment, and even reduce the quality of wear-resistant parts, including the furnace body and the multiple support feet installed at the lower end of the furnace body. The upper end is provided with an air extraction port, the side wall of the furnace body is provided with a furnace door, the lower part of the inner cavity of the furnace body is provided with a lower heating component, and one end of the lower heating component extends to the inner cavity of the heating box, and the lower heating component extends to the inner cavity of the heating box. The furnace entry component is provided above the heating component, and the furnace entry component is provided with a uniform heating device; the invention is especially suitable for uniform heating of wear-resistant parts, ensures the effect of heat treatment, and has high commercial prospects.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment for wear-resistant parts, in particular to a heating furnace for heat treatment of wear-resistant parts. Background technique [0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the surface of the workpiece. , to give or improve the performance of the workpiece. [0003] After the existing wear-resistant parts are formed, the surface or some thinner sections are prone to white structure due to the faster cooling rate, which increases ...
