Bell jar type electric vacuum bright annealing furnace
Bell type furnace
A brief
Bell jar furnace is a new type of energy - saving batch furnace. Mainly used for coil, coil, red copper, brass, alloy copper rolled silicon steel plate, used for non-oxidation bright heat treatment.
The structure of the body
The bell jar furnace is mainly composed of 1 heat shield, 2 furnace bottoms, 2 inner covers, cooling caps, valve brakes and pipes.
benefits
1. Strong convection cycle, shortening heat treatment cycle, high efficiency;
2. PPM sealing mechanism is adopted in the connection part to make the atmosphere more stable and avoid mixing hydrogen or other protective atmosphere with air;
3. Microcomputer intelligent instrument is adopted to control the furnace temperature, which can be controlled automatically.
