At the present time a new induction hardening facility is being put into operation (see picture). Its hydraulic struts make possible the treatment of components up to 10m in length and weighing as much as 16t. In order to obtain uniform hardening, measures have been taken to ensure especially uniform inductor routing and to maintain temperature control through the use of infrared measurements. Even in the case of an uneven alignment the space between inductor and component surface remains continually the same.

Just one example of the many challenges which hardening engineers must confront in the process of surface-layer hardening: Even before hardening, finished gravure rolls have already assumed through the erosion of etchings their final structure - neither overheating nor the finest of microfissures can be allowed to mar the sharp edges.

An early consultation with our hardening engineers helps to ensure that the most profitable technique and the optimal material for the application intended will be chosen.
