Roller consumption depends on three factors

② Roll material and its manufacturing quality;

③ Roller use and maintenance system

In this way, it can not only be durable under normal rolling, but also be less damaged under some abnormal rolling conditions. Therefore, it is necessary to strictly control the metallurgical quality of the roll or take external measures to enhance the bearing capacity of the roll. Reasonable roll shape, pass, deformation system and roll manufacturing conditions can also reduce the working load of the roll, avoid local peak pressure and prolong the life of the roll.
