Quenching and heat treatment of automobile parts
The quenching and tempering heat treatment of automobile parts can be divided into protective atmosphere quenching heat treatment and general quenching and tempering heat treatment. The protective atmosphere heat treatment can ensure that the parts will not cause surface oxidation, decarburization and other defects during the heat treatment process, and ensure the surface quality of the parts. When the working face of the part needs to be processed after the quenching and tempering treatment, the general heat treatment is adopted. According to the quality and size of the parts, the quenching and tempering heat treatment equipment is equipped with a mesh belt furnace, a cast chain furnace, a tray (material basket) push rod type furnace, a bracket furnace, a hanging continuous furnace and the like. Taking the heat treatment of automobile fasteners as an example, the development of quenching and tempering heat treatment technology mainly has the following aspects: Polycarbonate Roller Shutter Door Polycarbonate Roller Shutter Door,Motorized Polycarbonate Rolling Shutter Doors,Polycarbonate Transparent Roller Shutter Door,Full Vision Polycarbonate Door Dongguan HengTaichang Doors Co, Ltd. , https://www.dghtcdoor.com
(1) Furnace type Due to the radiant tube heating and the greatly improved life of the mesh belt, the domestic standard parts industry net belt furnace has been widely used. The mesh belt furnace has the advantages of uniform fabric, uniform heating, stable parts quality and good working environment. Especially for the heat treatment of high-strength bolts, the mesh belt furnace is used to ensure the quality.
(2) Application of carbon potential control technology Carbon potential control technology has been widely used in protective atmosphere quenching and tempering production lines. The carbon potential control technology is used to control the carbon potential in the furnace to ±0.03%, which ensures the heat treatment quality of the parts.
(3) Application of computer technology The computer can automatically complete the whole process of workpiece production according to the process setting, record and save various process parameters in the production of the workpiece, and have perfect fault diagnosis, display, safety warning and chain function.
(4) Application of rapid quenching oil and water-based quenching medium The application of rapid quenching oil ensures the inherent quality of heat treatment of high-strength bolt parts. The application of water-based quenching medium solves the quality problems of hardening of parts, hardening of quenching water and quenching of parts.
