Bell Type Bright Annealing Furnace for Brass,red copper
Brief
Bell type furnace is new type and energy-saving batch type furnace.Mainly used for coiled stock, pipe coil, coiled silicon steel sheet of red copper, brass, alloy copper for no oxygen bright heat treatment.
Structure
This bell type furnace is mainly composed of 1 heating shield,2 furnace base,2 inner cover,cooling cover, valve braket and pipeline.
Advantages
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.
