ABSTRACT:
A mill stand having a pair of work rolls cooperating with at least one backup roll. Bending forces are applied to at least one work roll at or adjacent the ends thereof. The work rolls may be offset with respect to the backup rolls in either an upstream or downstream direction, and the bending forces may be applied in the direction of offset. The forces may be applied to both work rolls. An opposing force may be applied to the opposite side of the work rolls intermediate the bending forces applied to the work roll ends either through the strip tension differential or a direct application. A rolling mill stand having a pair of cooperating work rolls and cooperating backup rolls has a pair of first auxiliary rolls applying forces at or adjacent the ends of the work rolls. The work rolls may be offset and the bending forces are applied in the direction of offset. Second auxiliary rolls may be provided intermediate the first auxiliary rolls to provide an opposing force.
