Vacuum furnace is usually composed of furnace, electric heating device, sealed furnace shell, vacuum system, power supply system and temperature control system. The sealing furnace shell is welded with carbon steel or stainless steel, and the sealing surface of the removable part is sealed with vacuum sealing material. In order to prevent the deformation of the furnace shell after heating and the heating of the sealing material, the furnace shell is usually cooled by water or air cooling. The furnace is located in the sealed furnace shell. Different types of heating elements, such as resistance, induction coil, electrode and electron gun, are installed in the furnace according to the furnace usage. There are crucibles in the vacuum furnace of melting metal, and some are equipped with automatic pouring device and manipulator for loading and unloading materials. Vacuum system mainly consists of vacuum pump, vacuum valve and vacuum gauge.
