Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part heat treatment, and particularly relates to a heat treatment furnace for automobile part treatment. BACKGROUND

[0002] In the current rapid development of the automobile industry, the performance requirements of automobile parts are increasingly stringent, and the strength, hardness, toughness and wear resistance of key mechanical properties directly determine the overall safety and service life of the automobile. As a core process in the manufacturing process of automobile parts, heat treatment can effectively control the internal structure of the material by controllable heating, holding and cooling treatment, thereby significantly optimizing the mechanical properties and meeting the use requirements under different working conditions. Among them, tempering treatment, as an important part of the heat treatment process system, is mainly used after quenching of the parts, by reheating them to a specific temperature and holding for a period of time, and then cooling, to eliminate the internal stress generated during quenching, stabilize the organization and size of the parts, and at the same time, improve the toughness on the basis of ensuring a certain hardness, to avoid cracking or deformation of the parts in subsequent use.

[0003] However, when the existing heat treatment furnace takes out the parts after tempering treatment, it usually needs to completely open the door to take out the parts in the furnace. During this process, a large amount of high-temperature heat in the furnace will be quickly lost to the outside, causing the temperature in the furnace to drop sharply, and a large amount of energy needs to be consumed to heat and warm up the furnace body again when the parts are processed again, increasing the production energy consumption and production cost. At the same time, the parts in the existing heat treatment furnace are usually placed in a static manner, i.e. the parts are directly placed on the support structure in the furnace. This placement method makes the parts in contact with the support structure heat poorly, and thus uneven heating occurs, which affects the stability of product quality.
