New Generation of Induction Hardened Rolls
Our bi-frequency machines feature two inductors operating simultaneously: one at high frequency (200 Hz – 800 Hz) and the other at low frequency (50 Hz – 200 Hz). The entire induction hardening process is automated and computer-controlled. The induction frequency is continuously adjustable, enabling varying hardening depths. These machines are also suitable for re-hardening used rolls and pre-heating rolls.
