The equipment adopts heat-resistant stainless steel bell cover and the furnace body is strictly sealed, so that the working material is isolated from the outside air. In the process of heating, heat preservation and cooling, the annealed materials are always protected by high purity nitrogen and hydrogen gas, so that the annealed materials keep smooth and bright without oxidation. Due to the strong convection fan installed in the furnace, the air in the furnace forms strong convection circulation, which makes the furnace temperature uniform. The temperature difference of each point in the furnace can be controlled within ± 5 ℃, so that the annealed material can obtain uniform physical and mechanical properties.

This equipment can be widely used for bright annealing of non-ferrous metal copper, aluminum alloy and ferrous metal, plain carbon steel, silicon steel, alloy steel, coil, wire, etc. Strong convection bell type bright annealing furnace has the advantages of high production efficiency, good product quality, low energy consumption, no pollution, automatic operation, safety and reliability. It is one of the internationally recognized advanced heat treatment equipment.

RZ type bell type annealing furnace each set of annealing furnace has two hearth, two inner hoods and one heating hood. When one cooling hood and one hearth are heating and holding, the other hearth is in the process of cooling and discharging. The same heating hood can heat two hearth alternately, which can save energy consumption and realize continuous production.
