Abstract

PURPOSE:To considerably increase the accuracy of plate thickness by actually measuring the actually measured values of rolling parameters immediate after the rolling material bites into the first and second stand, obtaining the deviations from the estimated values of plural factors and correcting the screw-woen conditions of the third and subsequent stands according to the deviations thus obtained. CONSTITUTION:Immediately after the rolling material 10 bites into the first stand 12a, a rolling load detecting part 14a detects the actually measured rolling load value P1 and inputs the same to an arithmetic unit 20. In the similar manner, the actually measured rolling load value P2 of the second stand is also inputted to the arithmetic unit 20, which then operates the differences DELTAP1, DELTAP2 from the separately inputted estimated loads, and operates the error DELTAK1 of the screw-down zero point fluctuation DELTAS01 and deformation resistance of the first stand. Next, the arithmetic unit operates the DELTASoi and DELTAKi of all the stands, obtains finish plate thickness deviations and the screw-down position correction quantities of the 3rd and subsequent stands, obtains the correction quantities of the number of revolutions of the work rolls and outputs these to screw-down position control units 16c thru 16n and work roll revolution number control units 18c thru 18n.
