[0002] Currently, vacuum heat treatment is a new type of heat treatment technology that combines vacuum technology with heat treatment technology. It not only significantly improves the vacuum gas cooling quenching capability, but also has the advantages of good surface brightness and minimal deformation after quenching, and is highly efficient, energy-saving, and pollution-free. In order to obtain the desired structure and properties, metal materials need to be cooled in a predetermined manner and rate. The workpieces treated in a vacuum oil quenching furnace have a good surface brightness, so they are widely used.
