bright annealing furnace for stainless steel wire

Bell Type Bright Annealing Furnace 1.Purpose This most advanced gas fired forced convection bell type bright annealing furnace is created by our company, all technical data is met the international requirements. It has novelty appearance, easily and uniformly temperature control accuracy, higher thermal efficiency, cost saving, rapid cooling, less energy consumption, safety operation, and easy maintenance. Under protecting atmosphere, copper coils can be bright annealed and free of oxidized stain. Copper coils need not to be acid washed, and de-oil treatment, thus effectively reduced pollution. This gas-fired bell type furnace is widely supplied to heat treatment cold-rolled sheet, non-ferrous coil, wire coil, tube coil, and core of transformer. Etc. It consists of a heating cover, two sets of cooling covers, 3 sets o inner covers, 3 sets of bases, 1 set o vacuum pump, and one set of atmosphere control valves and electrical control system. 2.
