Abstract

PURPOSE: To improve the plate thickness accuracy of a rolled stock by detecting variations in tension during rolling and eliminating influences of the variation on a thickness of the stock.
CONSTITUTION: A gap between rolling rolls is detected by a drafting device 3 adjusting the gap. A tension (a forward tension) acting on a rolled stock 1 between an (i) and an (i+1) stands is detected by a forward tension detector 7 and a tension (backward tension) acting on the stock 1 between an (i-1) and an (i) stand is detected by a backward tension detector 8. A roll gap correc tion amount ▵S of a rolling mill 2 is calculated by an arithmetic controller 10 based on the detected values of a gap, a rolling load, forward and backward tensions so as to equal a plate thickness of the stock 1 on the outlet side of the mill 2 to the reference value. The correction amount ▵S is sent to the drafting device 3, which adjusts the gap between rolling rolls based on the amount ▵S.
