Abstract: Trouble-free operation of an installation for rolling plates or sheets that have lost their rectangular form and have the form of a parallelogram is ensured by preventing the plate from meandering as it enters a rolling stand. A first rolling pass is carried out and, when the plate runs out from the rolling stand, it is determined whether the side faces of the plate are offset in relation to one another in the rolling direction. If the side faces of the plate are offset in relation to one another in the rolling direction, i.e. if the plate is parallelogram-shaped and has an oblique end, in a second rolling pass guiding elements of the rolling stand are set asymmetrically with respect to a centre line. A first guiding element for the side face, which is the first to enter the rolling stand in the second rolling pass, is thereby adjusted further away from the centre line than the second guiding element.

Abstract: A shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof. The device includes a plurality of split rolls provided in a width direction of a rolling material; a table which guides the rolling material and which is rotatably supported; a fixing member supported by the table; torque detectors for separately detecting loads acting on both ends of the split rolls when the rolling material comes in contact with the split roll as moments; supporting arms of which one end rotatably supports the split roll and the other end is supported by the fixing member through the torque detectors; a meandering amount computing unit for computing a meandering amount of the rolling material using the moments detected by the torque detectors, and a plate shape computing unit for computing a plate shape of the rolling material using the moments and the meandering amount.

Abstract: Provided is a shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof.
