Vacuum Molybdenum Wire Heating Furnace(Horizontal)
I. Usage
The electric furnace is vertical or horizontal and is not only suitable for the annealing, brazing, sintering, degassing of the metallic materials
under high vacuum, high temperature conditions, but also applied to the deshydroxy treatment of adapted materials.

III. Structure Descriptions
The Vacuum Molybdenum furnace mainly consists of furnace shell, heating elements, insulation reflective screen, vacuum system, electric
control system and so on.
1. The furnace shell is under dual watercooled layer structure with polishing stainless steel inner layer and highquality antiproof carbon
steel outer layer. There passes cooling water between the two layers, and the side of furnace is equipped with watercooled electrodes,
thermocouple and observation holes.
2. The heating element is made of high-temperature molybdenum wire or high-temperature molybdenum belt, and rational layout helps
improve the furnace temperature’s uniformity.
3. The insulation reflective screen is made of high-temperature molybdenum, molybdenum and stainless steel. Vacuum cleaning
reduces the gas discharge.
4. The vacuum system is made of oil diffusion pump and mechanical pump. The vacuum valve is the highvacuum 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.
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 controls the heating or cooling of temperature, and
there designed with 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.
