<p>PROBLEM TO BE SOLVED: To enable the restraint of asymmetrical component by obtaining the deviation of a shape mode coefficient in a low grade odd degree component and the deviation of a shape mode coefficient in a high grade odd degree component which is higher grade than the above component, in a normalized orthogonal function as the deviation and obtaining a rolling reduction levelling control and an asymmetrical control quantity of an interrflediate roll bender. SOLUTION: At the outlet side of a cluster rolling mill 10, shape detectors SE1 -SEn for detecting the shape containing the elongation in each section in the width direction of a material 1 to be rolled corresponding to each backup roil, are provided, and these shape detected signals are fetched to a shape detecting part 2 and processed, and the shape signal corresponding to the elongation in each section is obtd. and given to a shape control part 3. The shape control part 3 is made to store various items, size target, rolling schedule and rolling condition of the material 1 to be rolled, and calculates the shape controlling quantity, etc., in each pass to satisfy these conditions to execute the shape control of a rolling reduction leveling control device 14, intermediate roll bender control, etc. By this method, the high accurate shape control of the complex elongation of the material 1 to be rolled can be obtd.</p> |
