Abstract

PURPOSE: To carry out alays stable control for the sheet gauge, by installing the controller for controlling the peripheral speed of rolls in the main stand and the front stand correstpondingly to the deviation of the exit sheet gauge of arbitrary stand from the aimed sheet gauge, and for selectively controlling both stands correspondingly to the draft percentage.
CONSTITUTION: The exit sheet gauge of the n-th stand is detected by the sheet gauge detector 9, and the peripheral speed of the roll in the n-th stand is controlled by the automatic sheet gauge controller 10 of the n-th stand through the speed controller 8 correspondingly to the deviation of the detected sheet gauge from the aimed sheet gauge, and the back tension is given to the n-th stand so as to make zero the deviation in the sheet gauge. Further, the (n-1)th stand is controlled correspondingly to this deviation in the sheet gauge. Besides, the automatic sheet gauge controllers 10 and 11 of the n-th stand and (n-1)th stand are arbitrarily selected by the selector 15 correspondingly to the draft percentage of the n-th stand. According to this mechanism, the effective, safe, automatic sheet gauge control can be carried out in the continuous rolling work.
