vacuum tungsten furnace

The vacuum tungsten furnace operates regularly and there is no carbon inside, so carbon pollution is avoided This is an ultra-high temperature and high vacuum furnace for scientific research or industrial production. It is suitable for sintering transparent ceramics with high purity ceramics. Tungsten electrode is used for sintering and degassing under high vacuum. Vacuum sintering can also be used for tungsten and molybdenum products.

Inner shell is stainless steel, the outer layer is carbon steel and the water is cooled between the two layers.
Furnace shell with suction port, observation hole, thermocouple hole, the protection of the atmosphere import and export, explosion-proof mouth and so on.
The heating element is surrounded by a plurality of tungsten, molybdenum and stainless steel heating screens 
The bottom of the furnace is made by welding the inner and outer plates,  intermediate water-cooling, can be up and down to facilitate loading and unloading material.
