Abstract
PURPOSE: To make possible the elongation to be exactly, easily controlled, by connecting the elongation setter to the sheet elongation arithmetic unit, and the arithmetic unit to the draft controller, on purpose to correct the rolling load depending on the deviation obtained from those devices.
CONSTITUTION: In the rolling mill where the circumferential speed ratio of upper and lower work rolls 1, 2, is different, the sheet speeds on the feeding side and on the outgoing side are detected by the speed meters 21, 22, and are sent to the elongation meter 19. The ratio of integrated values, on the feeding side and the outgoing side for a specified time, is operated by the elongation meter 19, and its deviation from the signal given by the elongation setter 20 is operated. This deviation signal is sent from the proportional plus integral controller 18 to the draft controller 11 so as to control the screw down device 10 for holding constant the elongation. According to this mechanism, the elongation control can be simply operated, so that the product quality is improved
