Abstract

PURPOSE:To improve the sheet thickness accuracy by detecting rolling load variances caused by roll eccentricity in kiss rolling by a load cell, calculating a roll gap variation by the equation, and controlling a sheet thickness by changing drafting amounts. CONSTITUTION:Rolling load variances DELTAPE caused by roll eccentricity in kiss rolling is detected by a load cell 6 for continuous rolling of a rolled stock passed between rolls of a rolling mill. A roll gap variance amount DELTASE caused by roll eccentricity is calculated by the equation and a drafting device 8 is operated to change a drafting amount to cancel the amount DELTASE and sheet thickness control is performed. In the equation, M is mill constant. Hence, roll gap variation are correctly obtained.
