I,
Usage
The furnace is periodic operation
type, which uses the tungsten, tantalum as the heating
elements, and it\'s not only suitable for the high temperature
sintering of such refractory metals or inorganic non-metallic
materials as tungsten, tantalum, molybdenum and so on but also
applied to the degassing treatment of metal
materials.

III, Structure
Description
This vacuum high temperature
sintering furnace mainly consists of the furnace shell, heating
elements, insulation reflective screen, vacuum system, electric
control system and so on.
Â
1. The furnace shell is
under dual water-cooled layer structure with polishing stainless
steel inner layer and high-quality anti-proof carbon steel outer
layer. There passes cooling water between the two layers, and the
side of furnace is equipped with water-cooled electrodes,
thermocouple and observation holes.
Â
2. The heating element is made of
high-temperature tungsten filament or high-temperature tantalum
piece, and rational layout helps improve the furnace
temperature’s uniformity.
Â
3. The insulation reflective
screen is made of tungsten, tantalum and stainless steel.
Vacuum cleaning reduces the gas discharge.
Â
4. The vacuum system is made of
oil diffusion pump and mechanical pump. The vacuum valve is the
high-vacuum baffle valve designed and produced by our company, and
it can achieve the automatic control of high and low vacuum, with
the digital display and PLC.
Â
5. The main circuit of electric
control system is low voltage and high current input, the control
cabinet is produced according to the Siemens standards. Imported
digital displayed procedure controller automatically control the
heating or cooling of temperature, and there designed graphic
simulation screen on the control cabinet panel, which has human
design and easy operation, being direct. The control loop has
automatic protective function and alarm with sound and light, when
water break, over-temperature and over-current
occur.
