<p>PURPOSE:To attain the optimum control for meandering of a rolled stock by adjusting rolling reduction leveling quantity so as to eliminate the tensile deviation between one side and the other side in the moving direction of the rolled stock and controlling meandering of the rolled stock based on the signals of tensile deviation and deviation of rolling load. CONSTITUTION:The deviation between tensile signals 3A, 4A from tension detectors 3, 4 on one side and the other side in the moving direction of the rolled stock 1 which is rolled with a rolling mill 2 is determined and outputted with a signal output means 11, 12 for tensile deviation. The deviation of tensile signals 5A, 6A from rolling load detectors 5, 6 is determined and outputted with signal output means 13, 14 for deviation of rolling load. Rolling reduction leveling quantity is adjusted with adjusting means 9, 10 so as to eliminate the tensile deviation between both sides of the rolled stock 1. The output signal from the adjusting means is corrected so as to control the meandering of the rolled stock 1 based on the signal 12A of tensile deviation and the signal 14A of deviation of rolling load. By this way, accuracy of thickness and shape of the rolled stock can be made so as not to be adversely affected.</p> |
