ABSTRACT:
A control device for a continuous rolling machine effects feedback control by measuring vertical and lateral dimensions at a point after an ith mill stand, and by controlling the tension in the material between an i-1th and the ith mill stand and the position of the ith mill stand to reduce the differences between the detected dimensions and reference dimensions to zero. A shape correction device may be used which calculates lateral and vertical dimension change values for the i-1th stand, which are used to control the position of the i-1th stand and the tension in the material between an i-2th mill stand and the i-1th stand to assist in bringing the actual dimensional output values into coincidence with the reference values.
