Surface hardened rolls

Forged rolls for cold rolling fulfill the customer's demands for increased productivity, high reliability, safety of operation, finer surface quality, higher rolling speeds, and more demanding rolled materials and thus positively influence TCO (Total Cost of Ownership).

These properties are achieved with a combined heat treatment where the roll is quenched and tempered to the basic hardness first, and then the surface is hardened to reach the proper work hardeness. These rolls are surface hardened in a dual frequency induction hardening machine, followed by rapid cooling with liquid nitrogen below -140 °C, and then tempered at low temperature.

Surface hardened rolls are manufacured in the following dimesional range:

  • Up to 800 (33˝) mm diameter
  • Up to 5500 mm length and
  • Up to 8.000 kg (22,000 lbs) weight

Surface hardened rolls are made from high quality steel in accordance with customer requirement .
