What is the structure of the vacuum furnace?

The vacuum furnace uses a vacuum system in a specific space of the furnace chamber (a vacuum pump, a vacuum measuring device, a vacuum valve and the like are carefully assembled, and some substances in the furnace chamber are discharged, so that the pressure in the furnace chamber is less than a standard atmospheric pressure, The space inside the furnace chamber is thus in a vacuum state, which is a vacuum furnace.Vacuum-Induction-Melting-Furnace-For-Metal-Material-Melting-Processing-in-Lab

The vacuum furnace generally consists of a main machine, a furnace, an electric heating device, a sealed furnace shell, a vacuum system, a power supply system, a temperature control system, and an outside transport vehicle. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the detachable member is sealed with a vacuum sealing material. In order to prevent deformation of the furnace shell after heating and deterioration of the sealing material, the furnace shell is generally cooled by water or air cooled. brazing-furnace

The furnace is located in a sealed furnace shell. Depending on the furnace application, different types of heating elements, such as resistors, induction coils, electrodes and electron guns, are installed inside the furnace. The vacuum furnace furnace for melting metal is equipped with crucibles, and some are equipped with automatic pouring devices and robots for loading and unloading. The vacuum system is mainly composed of a vacuum pump, a vacuum valve and a vacuum gauge.Industrial-Vacuum-gas-Quenching-Furnace-with-capacity-1500KG
