Description:

Vacuum furnace is in square shape with double steel bar dense welding. The interlay has cooling water baffle plate which can ensure the cooling water evenly cool down each part of the furnace body. The electrode adopts end face seal which has high temperature seal property and good stability.

Method of temperature control: Closed circle PID programmable curve automatic temperature control.

Degree of uniformity: no more than ±5 ℃.

Working process:  degumming-sintering-cooling in continuous pattern.

Heating chamber: the insulation heating screen adopts overall composite carbon fiber construction, good insulation effect, less heat loss, easy maintenance and installation.

The heating parts consist of special graphite electrode and optimum heating graphite which can be used for a long time without fraction and easy change.

The inside furnace supporting adopts high strength graphite, with high temperature strength and large load capacity.

Vacuum system: consists of slide valve pump, roots pump, high vacuum oil diffusion pump, filtration device and pipe valve. The system adopts redundancy selection which can quickly realise vacuum.

The diffusion pump has a oil temperature monitoring system which can make the operation more expressive.

The simulation display screen which make the operation easy and visual.

Deguming system: consists of gum-taking device and connection pipeline. High degumming rate, easy gum-cleaning and little air pressure.

Inflation/Deflation system: equipped with ArN2 inflation device which can achieve spares air-loading directional gas sintering, quick cooling etc.
