<p>PROBLEM TO BE SOLVED: To form the warped quantity to zero or a small value so as not to develop any trouble in the pass of a rolled material with a rolling mill at the following step by measuring the warped quantity at the outlet side of a universal rolling mill and executing a feedback control to the warped quantity. SOLUTION: The warped quantity of the rolled material 3 is measured with a warp measuring instrument 7 at the outlet side of the universal rolling mill and the warp signal is outputted to a computing element 8. The computing element 8 controls a roll off-set correcting quantity with the measured value and a model equation and the calculated result is outputted to a controller 9. The controller 9 outputs a control signal to a hydraulic cylinder 10 and tapered plates are displaced 6. Roll chocks 4 supporting vertical rolls 1, 1a are shifted to a pass-line direction with the displacement of the tapered plates 6 and the roll off-set quantity of the vertical rolls 1, 1a is changed. By this method, moment is changed and the warped quantity is made to zero. The feedback control of the roll off-set quantity is executed at a prescribed control cycle.</p> |
