The vacuum hot pressing furnace body is the vertical furnace shell

The vacuum hot pressing furnace body is the vertical furnace shell, the inner layer is made of stainless steel cylinder and the outer layer is carbon steel. The jacket formed between the two layers can pass the cooling water to take away the heat transmitted to the furnace shell, so that the furnace wall temperature does not exceed 60℃, its upper and lower flange welding as a whole. The furnace frame is composed of upper beam, furnace frame, bottom and column, etc., as the upper and lower pressure head support.

The heating element in the furnace of vacuum hot pressing furnace is made of graphite, the thermal insulation material is made of graphite felt and graphite cylinder as heat insulation screen, and the indenter is made of high strength graphite.

The hydraulic pressure is automatically adjusted by electric input, equipped with hydraulic lock, steering valve and other related devices. The pressure and displacement are all digital display.

Vacuum sintering furnace is in the vacuum after hydrogen filling protection state, using the principle of medium frequency induction heating, the tungsten crucible in the coil to produce high temperature, through the heat radiation conduction to the work, suitable for scientific research units to refractory alloys such as tungsten, molybdenum and alloy powder forming sintering.

If it can be recovered as soon as possible when heating and cooling, restart the vacuum sintering furnace. If it takes a long time, keep the vacuum sintering furnace in its original state and let it cool down naturally.

The vacuum system adopts mechanical pump and oil diffusion pump, and is equipped with cold trap and unit. Vacuum measurement is composite vacuum gauge. The vacuum system is also equipped with an air discharge valve and an air filling valve, and the vacuum hose is made of stainless steel metal hose.
