Abstract

PURPOSE:To prevent sudden horizontal bend that is generated at the tip of rolled stock by detecting deviated amount of the width center of rolled stock from the center between right and left edger rolls, shifting the right and left edger rolls before biting with an edger and returning the edger rolls before reaching a horizontal roll. CONSTITUTION:On the inlet side of the edger 2, a horizontal deviaion detector 6 with which the deviated amount x of the width center 14 of rolled stock 4 from the the center 15 between the right and left edger rolls 2a, 2b is provided. Next, an arithmetic unit 8 for shift quantity to which that detected signal 7 is inputted, with which the horizontal deviated amount x0 of the tip part of rolled stock 4 is operated, with which the shift command signal 9 by which the edger rolls 2a, 2b are shifted with the horizontal deviated amount x0 is outputed, on the other side, in which the edger load-on signal from a load cell 13 is inputted and from which the shift command signal 9 for returning the edger rolls 2a, 2b before the tip part of rolled stock 14 is bitten in the horizontal mill 1 is outputed, the device 11a, 11b for controlling the position of edger roll and the load cell 13 with which the edger load-on signal 12 is outputed to the arithmetic unit 8 for shift quantity are provided.
