low distortion surface hardening treatment
induction hardening
what is induction hardening?
This involves heating applied rapidly and locally to the steel component followed by fast cooling (quenching). High frequency electric fields quickly heat the surface of the component via inductor coils, which is then quenched using water. This results in a localized hardened layer at the surface.
Different shaped inductor coils are available and can be made to suit.
the process
By using a coil-shaped conductor made of copper, induction hardening generates an electromagnetic field into which the material is placed. This creates an electrical voltage in the material itself, which in turn generates heat. As a result, the material receives the necessary hardening temperature. Both warming up time and time at temperature are reached quite quickly. The temperature can be regulated by the current strength on the coil-shaped conductor and by the duration of the power supply.
Induction Hardening offers a cost-effective low distortion surface hardening treatment to steels, particularly large components where an increase in surface hardness is required whilst maintaining core properties.
We have a hugely comprehensive range of handling equipment, which includes horizontal and vertical fixtures and the ability to manufacture special handling equipment to your individual requirements for small batch or high-volume production.
fields of application
Induction hardening is used for the hardening of surface layers. The microstructure is transformed by induction, for which the material must have a carbon content of at least 0,35%.
This method is used primarily for workpieces that are prone to wear on the surface, as well as for components with a complicated shape. Because advantages of induction hardening are i.a. the possibility of partially harden components in an uncomplicated way and the option of achieving extremely thick layers. In addition, the throughput times for induction hardening are comparatively short. The process requires special know-how and the use of complex tools and systems.
