Patent

CA 2276113

A system and method for improving properties of a metal strip during rolling between rotating upper and lower work rolls in a mill stand, for reducing work roll edge wear, for improving distribution of thermal expansion of the work roll during rolling, for reducing required rolling torque for achieving a particular strip thickness reduction, and for increasing the tonnage of rolled strip between roll changes, by continuously shifting the rotating work rolls during rolling to impart a spiral motion to the work rolls, and by online grinding, heat rehardening and cooling of the work rolls outside the mill stand.
