Abstract

PURPOSE: To make the function of the tension-monitoring thickness controller to effectively work, and to perform the thickness control in good accuracy, by making the output of the controller to always stay in the limit of the limiter.
CONSTITUTION: If the thickness deviation on the run-out side of the final stand is positive, the output of the controller 9 changes according to the output of the thickness detector 8, and the controller 9 works to slow down the speed of the roll 3 of the final stand. If the output of the controller 9 increases and reaches the level of the upper limit set in the relay 11, the relay 11 is actuated to close the contact 12, and the control unit 13 produces a command to reduce the rotational speed of the roll of the first stand. Hereby, the tension is increased between the first and the second stands, and the thickness is reduced on the run-out side of the second stand. As a result, the thickness on the run-out side of the final stand is reduced. Then, the output of the controller 9 begins to decrease, so that the control can be performed without reaching the limit point of the limiter 10, and the function of the control block, that is the tension-monitoring thickness controller, is fully developed.
