Abstract

PURPOSE: To improve the accuracy of sheet thickness, by operating the draft correction value of the rolling stand, and by correcting the aim thickness of sheet depending on the output of the load controller.
CONSTITUTION: The thickness operator 12 operates the run-out side sheet thickness, the sheet speed, and the forward slip, depending on the data of the data input unit 11, and inputs these data to the thickness tracking unit 13. This tracking unit 13 operates the traveling distance of the rolled material and shafts the thickness. The control arithmetic unit 14 operates the draft correction value for each stand, and inputs the result to the data output unit 15. The aim thickness is corrected by the load balance control arithmetic unit 17. That is, the aim value of the run-out side sheet thickness, to be the aim thickness, is corrected with variation of the feed-in side sheet thickness while the rolling work is being controlled, and the load balance over whole rolling stands is controlled. The data output unit 15 adds the present draft position value to the output value of the control arithmetic unit 14, and inputs the result of addition as the draft position to the screw down devices 41W46. At the same time, the speed correction value is inputted to the speed controllers 51W56. The model adaptation correcting unit 19 corrects the adaptation of the correction factor and inputs the result to the sheet thickness operator 12.
