Abstract
A method of controlling an edging opening in a rolling mill, comprising measuring a width distribution of a plate to be rolled at an inlet of an edging roll in the rolling mill, calculating beforehand a width deviation distribution and a length in the moving direction of the plate at an irregular deformation portion caused in a rolling process in accordance with a predetermined pass schedule and a target width deviation distribution of the rolled plate required at an outlet of the rolling mill, calculating an optimum edging opening variation distribution using a plate width adjustment efficiency calculated on the basis of the beforehand calculated value and supplying the optimum edging opening variation distribution to an edging opening setting unit for the feedforward control.
