Description

technical field [0001] The invention relates to the field of gear heat treatment, in particular to a heat treatment device for an automobile transmission gear. Background technique [0002] Quenching is a part of the heat treatment process. The steel is heated above the phase transition temperature, and after a certain period of time, it is rapidly cooled in a cooling medium to obtain a martensitic structure. The quenching process is directly related to the service performance and life of the workpiece, and the selection of quenching medium is the key to improving the quality of the workpiece. Quenching oil is a process oil for quenching, used as a cooling medium, which can reduce the cracking and deformation of the workpiece and enhance the hardness of the workpiece. Quenching oil has been used under harsh conditions of high temperature and continuous operation for a long time, requiring the oil to have good anti-oxidation, anti-thermal decomposition and anti-aging propert...
