Abstract
PURPOSE: The controller for exactly, easily controlling the elongation of the sheet independently of the eccentricity of the roll, by connecting the elongation setter to the elongation arithmetic unit, and the work-roll-circumferential-speed-controller to the arithmetic unit, on purpose to correct the circumferential speed of the roll depending on the deviation obtained from above stated devices.
CONSTITUTION: In the rolling mill where the circumferential speed ratio between the upper and lower work rolls 1, 2, are different, the sheet speeds on the feeding side and on the outgoing side are detected by speed meters 19, 20, and are sent to the elongation meter 17. The ratio, between the integrated values of speeds on the feeding side and the outgoing side for a specified time, is operated by the elongation meter 17 which operates the deviation of this inputted value from the signal given by the elongation setter 18. This deviation signal is sent from the proportional plus integral controller 16 to the speed ratio distributor 14, and is compared with the set signal given by the speed ratio setter 15; hereby, the speed ratio between the upper and lower work rolls 1, 2, is adjusted. This value is sent to the drive controllers 12, 13, on purpose to control the driving motors 10, 11, for the work rolls 1, 2; as a result, the elongation of the sheet 9 is controlled to constant value
