[0002] Tempering furnace is mainly used for tempering metal parts, as well as quenching, annealing and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, aluminum plates, etc. Its main purpose is to improve or adjust the hardness and strength of the material, eliminate the residual stress generated during the quenching process, optimize the microstructure of the material, improve the wear resistance and fatigue resistance, and adjust or improve other properties of the material, such as electromagnetic properties and corrosion resistance. The outer shell of the tempering furnace is usually welded by steel plates and steel sections, and the trolley inside is also welded by steel sections and steel plates. The trolley reduces heat radiation and convection losses through soft contact with the furnace lining and sand sealing mechanism, thereby effectively ensuring the sealing of the furnace body.

[0003] Tempering furnace plays a vital role in metal processing. Its main functions include the following: First, the tempering furnace can adjust the hardness and strength of the metal. Through tempering treatment, the residual stress and brittleness generated by the metal during the quenching process can be eliminated, so that it can reach the required hardness and strength requirements. Secondly, the tempering furnace helps to improve the wear resistance and fatigue resistance of the metal. During the processing and use of metals, they often need to withstand various external forces and friction, and tempering treatment can optimize the microstructure of the metal, enhance its wear resistance and fatigue resistance, and extend its service life. In addition, the tempering furnace can also adjust or improve other properties of the metal, such as electromagnetic properties and corrosion resistance. This is of great significance to meet the requirements for the performance of metal materials in specific use occasions.
