Abstract (en)
[origin: EP0972581A2] The actual rolling force and the resultant roll gap increase are determined. A roll gap correction is determined on the basis of this roll gap increase and a target roll gap in such a way that the actual roll gap approximates the target roll gap. The roll gap correction is implemented within a roll stand control interval.
