ABSTRACT:
A tandem rolling mill is operated such that roll stands of an upstream stage of the mill adjacent to a strip inlet thereof are positioned relative to each other to effect a strip crown control or an edge drop control, while roll stands of a downstream stage of the mill adjacent to a strip outlet thereof are operated to axially shift the downstream stage work rolls cyclically to distribute roll wear and thermal crown in the axial direction thereof.
