What are the components of the vacuum hot pressing sintering furnace structure?

The vacuum hot-pressing sintering furnace includes a sintering furnace and a vacuuming part. The sintering furnace includes a furnace body and a heating chamber installed in the furnace body. The sintering furnace is equipped with six current-leading electrodes. There are the upper beam of the hydraulic press and the lower beam of the hydraulic press. The upper beam of the hydraulic press and the lower beam of the hydraulic press are connected by four pillars to form a whole; the upper pressure head is composed of the upper water-cooled pressure head and the upper graphite pressure head, and the lower pressure head is composed of the lower water-cooled pressure head and the lower Graphite indenter is connected, the upper indenter and the lower indenter are inserted into the furnace body from the indenter through holes on the upper and lower end faces of the furnace body and the heating chamber respectively, and the upper and lower graphite indenters are respectively inserted into the heating chamber , The upper and lower indenters can move up and down.

The vacuum furnace is generally composed of a furnace, an electric heating device, a sealed furnace shell, a vacuum system, a power supply system and a temperature control system. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the detachable part is sealed with a vacuum sealing material. In order to prevent the furnace shell from being deformed after heating and the sealing material is heated and deteriorated, the furnace shell is generally cooled by water cooling or air cooling. The furnace is located in the sealed furnace shell. Depending on the purpose of the furnace, different types of heating elements are installed inside the furnace, such as resistors, induction coils, electrodes, and electronics. There are crucibles in the hearth of the vacuum furnace for smelting metals, and some are equipped with automatic pouring devices and manipulators for loading and unloading materials. The vacuum system is mainly composed of vacuum pump, vacuum valve and vacuum gauge.
