Surface hardening heat treatment
Sorbit has its own heat treatment operations. Depending on the roll dimensions and the required characteristics, the induction hardening can be performed with a single or double inductor. Also, there is a choice between a lower and a higher frequency. The double frequency enables a wide range of flexibility with technological parameters.
