Abstract

PURPOSE: To stabilize sheet thickness and width regardless of measurement noise and to improve accuracy by calculating the sheet width from stored load value at a front stage vertical rolling mill and horizontal rolling mill for the metallic material and the stored width value of a rolled sheet and subjecting the width at a rear stage vertical rolling mill to approximate value control.
CONSTITUTION: The metallic material 1 is rolled by the front stage vertical rolling mill and horizontal rolling mill 4, 5 and is further rolled by the rear stage vertical rolling mill and horizontal rolling mill 2a, 3a. the width of the metallic material emitted from the vertical rolling mill 5 is detected by a width gage 9 and is stored in an inlet side width memory device 22a. The values detected by load meters 6, 7 of the rolling mills 4, 5 are stored in both rolling load memory devices 22b, 22c. The stored values are put into an inlet side width calculator 40 which in turn makes the approximate value control of the width at the rolling mill 2a by operating a vertical roll correction position calculator 23a and a vertical roll position controller 25. The abnormal width part is controlled by the approximate value, by which the thickness and width of the sheet are stably controlled with the high accuracy in spite of noise inclusion.
