The bell annealing furnace is a kind of equipment for high-quality annealing. In the furnace, pure hydrogen or nitrogen or ammonia decomposition gas with strong convection circulation is used as the protective gas for the annealing process, and the annealing process of the products to be annealed is completed in a protective atmosphere. Compared with ordinary bell-type furnaces, it has the advantages of high production capacity, uniform mechanical properties, high surface cleanliness, safety and reliability, etc., which greatly improves the quality of annealing products.

Scope of application: the bell annealing furnace is used for spheroidized annealing, annealing, quenching, normalizing and solid solution of steel, stainless steel, copper/ alloy and aluminum industries.

We can provide high-quality bell annealing furnace according to your needs, please feel free to contact us!
