Abstract
Width and thickness of a hot-rolled and descaled strip are controlled by performing, in a line in which the strip runs, a rough control step for reducing correction of the width and the thickness of the strip in only the longitudinal ends thereof and a fine control step for reducing correction of the width and the thickness of the strip over the entire length thereof, respectively at least one time, so that the desired width and thickness of the strip are obtained in the last reduction.
