Bell Type Furnaces for Tempering

Product Introduction

Our Bell Type Furnaces for Tempering are specifically engineered to optimize the mechanical properties of heat-treated metal components, such as hardness, toughness, and ductility. Tempering is a crucial post-quenching heat treatment that reduces brittleness and relieves internal stresses, making the material more suitable for its intended application. 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 tempering furnaces ensure consistent and predictable results, making them ideal for a wide range of industries requiring high-quality, stable metal parts.

Working Principle

Bell type furnaces for tempering operate by carefully reheating previously quenched metal components to a specific temperature below the critical point, holding them at that temperature for a defined period, and then 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 environment. The furnace heats the components uniformly, allowing the martensite structure (formed during quenching) to transform into a more stable and ductile microstructure. This transformation reduces brittleness and internal stresses, enhancing the material's toughness and impact resistance. The precise control over temperature and holding time is crucial for achieving the desired balance of hardness and ductility. After the tempering cycle, the components are typically cooled in air or a controlled atmosphere, depending on the material and desired properties. The bell-type design allows for efficient batch processing and precise control over the tempering cycle.
