ABSTRACT:
A rolling mill comprising an actuator for controlling shapes or conditions of work roll surfaces during rolling and a flatness meter for detecting broadwise flatness of rolled strip to generate an output signal whereby the actuator is operated so as to control the flatness of strip, the output signal being analyzed into a plurality of evaluation indexes. Each of the evaluation indexes is converted by a membership function into a fuzzy quantity having one of a predetermined number of values. These fuzzy quantities are subjected to fuzzy reasoning consisting of a plurality of control rules to set the control value of the actuator.
