Shape detection device and shape detection method

摘要

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.
