Bell Type Furnaces for Annealing
Optimizing Material Ductility and Workability
Product Introduction
Our Bell Type Furnaces for Annealing are specifically designed to enhance the ductility, reduce hardness, and improve the workability of various metal components. Annealing is a critical heat treatment process that involves heating a material above its recrystallization temperature, holding it at that temperature for a specific duration, and then slowly cooling it. This process alters the microstructure of the material, making it softer, more ductile, and less brittle, which is essential for subsequent manufacturing processes like forming, machining, or drawing. These furnaces feature a unique bell-shaped movable heating chamber that is lowered over a stationary hearth, allowing for efficient loading and unloading of large or heavy components. With precise temperature control and uniform heating, our bell type annealing furnaces ensure consistent and predictable results, making them ideal for a wide range of industries requiring high-quality, malleable metal parts.

Working Principle
Bell type furnaces for annealing operate by heating metal components to a specific temperature above their recrystallization point, holding them at that temperature for a defined period, and then slowly cooling them. The process begins with loading the workpiece onto a stationary furnace base. A bell-shaped heating chamber is then lowered over the base, creating a sealed retort. The chamber is purged with a protective atmosphere to prevent oxidation and decarburization during heating. During the soaking phase, the material's internal stresses are relieved, and its grain structure is refined, leading to increased ductility and reduced hardness. The slow cooling rate allows for the formation of a more stable and uniform microstructure. This controlled process ensures that the material achieves its desired mechanical properties, making it easier to form, machine, or draw in subsequent manufacturing steps. The bell-type design allows for efficient batch processing and precise control over the annealing cycle.
Process Flow
Material Loading
Workpiece is loaded onto the furnace base, and the bell-shaped chamber is lowered and sealed.
Heating & Soaking
Material is heated to annealing temperature and held for a specified time under protective atmosphere.
Controlled Cooling
Material is slowly cooled at a controlled rate to achieve desired metallurgical properties.
Unloading
Annealed material is removed from the furnace for further processing or inspection.
