Abstract: A dimension control device for continuous rolling machine includes a correction mechanism for correcting a set tension of the rolling machine in accordance with temperature variations of a rolling material. With such a dimension control device, the width of the rolling material is controlled to a contstant at all times regardless of any variation in the temperature.

Abstract: A control device for a continuous rolling machine adjusts the rolling position of an ith mill stand to correct a first rolling material dimension and simultaneously controls the rolling position of an (i-1)th mill stand to adjust a perpendicular dimension of the rolling material to compensate for changes caused by the adjustment of the rolling position of the ith mill stand.

Abstract: A control device for a rolling machine includes a forecaster for predicting a change in the lateral dimension of a rolled material at the exit of a downstream mill stand based on dimensional variations, and a mechanism by which the tension on the material between two mill stands is altered in accordance with the forecast value, to control the lateral dimension of rolled material exiting the last of a series of mill stands.

Abstract: A rolling mill control device detects a dimension or dimensions of a product material between two mill stands, and forecasts a width deviation value of the material at a downstream stand on the basis of rolling characteristics of the material, etc. The position of an upstream stand is then varied to reduce the forecast value to zero. Feedback control is also effected on the position of the upstream stand based upon the difference between a reference width and an actually measured value.

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.
