High Vacuum Furnace This electric furnace is a very cost-effective vacuum furnace. Low price, simple operation, excellent vacuum effect, good temperature field uniformity. It is used for high temperature vacuum sintering, annealing, tempering and aging treatment of ceramic materials, ceramic metal composites, refractory metals, and alloy materials, as well as vacuum brazing of alloy tools and superhard materials. Pneumatic High Temperature Vacuum Furnace Easy To Operate With Air Inlet Vacuum up to 7* 10^(-3)pa (two-stage rotary vane vacuum pump+roots pump+diffusion pump unit) The highest temperature 1200 ℃ or 1700 ℃ is optional. Designed with air inlet and exhaust port, it can be used for vacuum pumping or filling with inert gas. Pneumatic vacuum valve, easy to operate. Helium mass spectrometry leak detector vacuum pickup, ensure the vacuum leakage rate is lower than0.67Pa/h. Use alumina ceramic fiber furnace and resistance wire or silicon molybdenum rod heating. At the same time, the cost of the electric furnace is greatly reduced. Double water-cooling, furnace shell surface temperature 50 ℃ or less. High strength carbon steel, external electrostatic spray, beautiful and generous. 50 programmable temperature meter PID adjustment. Upper limit alarm, deviation alarm, automatic stop at the end of the program operation, no man on duty. Standard Parts: High-temperature gloves Crucible clip Operation Manual Optional Parts: Independent control cabinet PLC automatic control system Rapid furnace cooling system
