What is induction tempering?
Induction tempering is a heating process that optimizesĀ mechanical properties such as toughness and ductility
in workpieces that have already been hardened.
What are the benefits?
The main advantage of induction over furnace temperingĀ is speed. Induction can temper workpieces inĀ minutes, sometimes even seconds. Furnaces typicallyĀ take hours. And as induction tempering is perfect forĀ inline integration, it minimizes the number of componentsĀ in process. Induction tempering facilitates qualityĀ control of individual workpieces. Integrated inductionĀ temper stations also save valuable floor space.
Where is it used?
Induction tempering is widely employed in the automotiveĀ industry to temper surface-hardened componentsĀ such as shafts, bars and joints. The process is alsoĀ used in the tube and pipe industry to temper throughhardenedĀ workpieces. Induction tempering is sometimesĀ performed in the hardening station, sometimesĀ in one or several separate temper stations.
What equipment is available?
Complete HardLine systems are ideal for many temperingĀ applications. The chief benefit of such systemsĀ is that hardening and tempering are performed byĀ one machine. This delivers significant time and costĀ savings in a small footprint compared to alternativeĀ technologies. With furnaces, for example, one furnaceĀ often first hardens the workpieces, with a separate furnace
then being used for tempering. Solid stateĀ DAWEIĀ Induction HeatingĀ Systems are also used forĀ tempering applications.
