Abstract
A method for hot rolling and cold rolling metal strip to a finish strip thickness, profile and flatness in a series of rolling mills each having roll bending and roll crossing capabilities to effect a plurality of roll gap profiles. A control method utilizing mathematical models of the roll gap profiles and strip profile is used to select and set the roll bending and roll crossing to a preferred configuration based on secondary effects of possible combinations so as to produce finished metal strip having desired thickness, profile and flatness characteristics.
