Abstract
PURPOSE:To control the fluctuation of the sheet breadth on the exit side to minimum, by measuring the breadth and temperature of sheet after the rough rolling for every specified length, by operating the variation of the inter-stand tension from the deviation between above measured breadth and the forecasted breadth of the sheet after the finish rolling, and by delivering the operated result to the finish rolling correspondingly to each point of measurement. CONSTITUTION:The breadth and temperature of sheet on the exit side of the roughing mill are measured for every specified length over total length of the material 6 to be rolled, by the breadth meter 4 and thermometer 5, and these measured values are inputted to the arithmetic memory unit 7 for the set tension value. Information about the material 6 after the finish rolling is inputted to the draft schedule setter 9 and the arithmetic memory unit 7 for the set tension value. The setter 9 carries out the operation for the finishing pass schedule and the control for setting the reduction of each finishing stand, and inputs thus obtained results to the arithmetic memory unit 7 for set tension value. From this input, the breadth of sheet after finish rolling is forecasted, and the deviation from the aim finishing breadth is obtained, and the variation of the set inter-stand tension value is operated. The timing of arriving of each measuring point of the material 6 at each stand is operated, and the set value variation of the tension is inputted to each of controllers 21- 23 for the inter-stand tension, and the specified breadth variation is given to material existing between each stand.
