Abstract

PURPOSE: To prevent the tear of sheet and excess reduction, and to improve the accuracy of thickness of the rolled product, by arranging the tension controller for controlling the speed-control system so as to keep the deviation between the output of the tension setter and the output of the tension detector, within the allowable range.
CONSTITUTION: The signal of the tension detector 26, arranged between the rolling stands 10, 12, in the first stage, is inputted to the tension controller 30. The thickness of the strip 6 is detected by the gaugemeter 20, and the deviation from the aim value is inputted to the thickness controller 24. The output of this thickness controller 24 is inputted directly to the speed control system 22 in case of the conventional system; however, in this method, above output is once inputted to the tension controller 30. Next, the aim value set in the tension setter 28 is changed correspondigly to the output of the thickness controller 24; and the speed of the work roll 14 is controlled so as to make the thickness on the exit side of the rolling stand 12 equal to the aim value through the speed control system 22. Accordingly, the interstand tension is cascade controlled by the output of the thickness controller 24, and the accuracy of the product thickness in heightened.
