Heat treatment of rolls
Depending of the steel, the heat treatment of the rolls is performed in vertical furnaces with a gas protective atmosphere
or in surface hardening machines.
The whole heat treatment process is digitally controlled with a central computer. The data is always available for later
use and research.
A quality steel and the heat treatment give to the rolls all the necessary characteristics, as:
• breakage resistance;
• crack/spalling/pitting resistance;
• wear resistance.
