<p>PURPOSE:To eliminate troubles such as recurrence of a camber in the succeeding rolling process and to achieve a high yield by controlling to correct a chamber and wedge of a rolling plate concurrently. CONSTITUTION:A camber and a wedge amount of a rolling plate after rolling at the (i)th pass selected optionally except at least two final plate rolling passes are obtained by estimation or actual measurement. The target camber and wedge amounts after rolling at the (i+1)th pass by which the camber and wedge amounts at the succeeding (i+2)th and the following passes are to be zero are estimated based on the chamber and wedge amounts at the (i)th pass and the following pass schedule. A corrective amount for a difference between a drafting down position of the work side and the driving side of a rolling mill after the (i+1)th pass based on the above target wedge amount. The drafting down position of the both sides is set in accordance with the corrective amount and the rolling mill is controlled to perform rolling in the succeeding (i+1)th and other following passes.</p> |
