High Efficiency Bell Annealing Furnace Strong Convective Circulation
1. Strong convective circulation,shortening heat treatment cycle and high efficiency;
2. Using PPM sealing mechanism in the connection part, more stable atmosphere, can avoid H2 or other protective atmosphere combined with air;
3. Using the microcomputer intelligent instrument to control furnace temperature, can perform auto control.
Introduction of Furnace
The bell type annealing furnace is used for annealing the steel strip, aluminum strip and copper strip. The furnace loading capacity can be reached to 60Tons(Max.). The loading diameter can be reached to 2.6 meters(Max.) and the loading height can be reached to 3.7 meters(Max.).
(1) 100% hydrogen or 75% hydrogen or nitrogen system
(2) High convection flow heating
(3) Consistent mechanical properties on annealing material
(4) Optimized control program
(5) Minimize production cost
(6) High productivity
(7) Customized design for steel, cooper, aluminum and alloy; strip, wire and tube.
This bell type annealing furnace is mainly composed of 1 heating shield,2 furnace base,2 inner cover,cooling cover, valve braket and pipeline.
