Bell Annealing Furnace by Therelek
Bell Annealer brings in excellent temperature uniformity, consistent quality and good production rates. Bell Furnace is suitable for black, bright and spherodized annealing of steel coils, non-ferrous strips, wires and general heat treatment processes up to 1100Ā°C. Bright annealing of cold-rolled steel strip coils and heat treatment of medium and thick hot-rolled plate, long products and wire coils are done using a bell-type furnace.
Type of furnace is usually rectangular or cylindrical form, single or multi-stack gas or electrically heated. Continuous purging of ammonia is deployed throughout the annealing cycle to avoid decarburizing. Overhead crane is used to load the base and move the equipment. Coils are tilted to the right position and placed on the annealing base.
The convection and heat transfer occurs in the base assembly. Forced atmosphere circulation is used with the help of radial fans for temperature up to 950Ā°C to improve convection. The cooling happens when the furnace is removed with inner cover acting as a protective atmosphere. In both strip annealing and wire annealing, the convection flow goes up on the sides and down the centre.

Applications
Annealing
Bell type annealing furnace is widely used for annealing of steel coils. The coils can be of steel strips, steel wire or any other shape which can be loaded in the furnace.
Wire Annealing
Annealing involves heating the wire to a specific temperature before cooling it at a prescribed rate in order to achieve the desired result. Annealing is used with the goal ofĀ increasing the ductilityĀ of the wire andĀ reducing the hardness. This allows the wire to be flexible while still remaining durable. With these properties, annealed wire is self-tying and can stay in place when wrapped around itself.
