When the metal is heated, the workpiece is exposed to air, and oxidation and decarburization (i.e., reduction in carbon content on the surface of the steel part) often occur, which adversely affect the surface properties of the heat-treated part. Metals are therefore usually heated in controlled or protective atmospheres, in molten salts and in vacuum, but also in protective coatings or packaging. The heating temperature is one of the important process parameters of the heat treatment process, and the selection and control of the heating temperature are the main problems for ensuring the heat treatment quality. The heating temperature varies depending on the metal material to be treated and the purpose of the heat treatment, but is generally a temperature above the transformation temperature to obtain a high-temperature structure. In addition, a certain time is needed for conversion, so when the surface of the metal workpiece reaches the required heating temperature, the surface of the metal workpiece needs to be kept at the temperature for a certain time, the internal temperature and the external temperature are consistent, the microstructure is completely converted, and the time is called as heat preservation time. When high-energy density heating and surface heat treatment are adopted, the heating speed is extremely high, generally, the heat preservation time is short, and the heat preservation time of chemical heat treatment is long. Therefore, the heat treatment of the workpiece needs a furnace with a vacuum environment to ensure smooth heat treatment and high heat treatment efficiency, thereby producing an aging heat treatment vacuum furnace, and the aging heat treatment vacuum furnace is generally large in shape and suitable for heat treatment of large-sized workpieces and is large and small in size for small-sized workpieces and parts.
