Abstract
PURPOSE: To improve the accuracy of the straightening work and the working efficiency, by detecting the shape of the strip after undergoing the straightening pass, and by automatically controlling the rolling reduction of each roll unit according to the signal of above stated shape detector.
CONSTITUTION: The shape of the strip is detected by the shape detector 17 installed on the run-out side, and the shape signal is inputted to the arithmetic unit 18 which then compares this signal with the previously set data; if the detected value exceeds the allowable range, the signal is produced from the arithmetic unit 18 and is inputted to the control unit 19. The control unit 19 converts the shape signal into the motor drive command signak separately for every kind of the shape signal, and the motors 11, 12, 13, are driven by this command signal; hereby, the adjustment of the rolling reduction is performed for each roll unit.
