Working Principle
Box type furnaces for tempering operate by reheating previously hardened (quenched) materials to a specific temperature below their critical point, holding them at that temperature for a set period, and then cooling them. This process aims to reduce the brittleness and internal stresses that develop during quenching, while simultaneously improving the material's toughness and ductility. The furnace chamber is typically heated by electrical resistance elements, and forced air circulation often ensures excellent temperature uniformity throughout the load. Precise temperature control is crucial, as the tempering temperature directly influences the final mechanical properties of the material. During the holding phase, atomic rearrangements occur within the material's microstructure, leading to the precipitation of fine carbides and a more stable, less brittle structure. The cooling rate after tempering is generally less critical than after quenching, often involving air cooling or a controlled furnace cool.
Process Flow
Loading Quenched Parts
Previously quenched workpieces are loaded into the tempering furnace chamber, ensuring even distribution for uniform heating.
Heating to Tempering Temperature
The furnace heats the parts to a precise tempering temperature, typically below the critical point, with controlled ramp rates.
Soaking at Temperature
Workpieces are held at the tempering temperature for a specified duration to allow for stress relief and microstructural changes.
Cooling & Unloading
Parts are cooled, usually in air or a controlled furnace cool, then unloaded and prepared for subsequent processes or inspection.
