Abstract
This disclosure relates to a control for a rolling mill in which a signal representing the required stretch of the mill for a desired thickness of product and roll gap setting, which stretch is first employed to set the initial roll gap predicated on a predicted rolling pressure, is compared with a signal representing the actual stretch of the mill during rolling. A third signal is produced representing the difference between the first and second signals and which equal the amount which the product differs from the desired gage due to improper initial estimate of predicted rolling pressure employed to set the initial roll gap and, consequently, the required change that must be made to the roll gap to produce a product of the given thickness.
