<p>PURPOSE:To roll a material to a prescribed plate thickness with a good shape with a less number of stands by providing an offset rolling mill having horizontal press rolls provided with high capacity for controlling the shape in the final stage of a tandem rolling line. CONSTITUTION:A prescribed gap value is maintained in the 1st stand 1 by the signals from thickness gauges 11, 21, a load cell 13 and a lateral gap compensator 14. A driving motor 17 is controlled by the signals from the gauge 21 and a tension detector 12 and is maintained at a prescribed volume speed. Rolling down is corrected in the 2nd stand by the signals from a tension detector 12 and a lateral gap compensator 24, and a motor 27 is controlled by a thickness gauge 31 and a tension detector 22 so that the prescribed volume speed is maintained. The rolling down is corrected in the 3rd stand 3 which is the final stage by the signals from the detector 22 and a lateral gap compensator 34 and a driving motor 37 is controlled by the signals from the gauge 31 and a tension detector 32.</p> |
