Abstract
The invention relates to a rolling mill stand including an automatic strip steering and control system, comprising at least two rolls arranged alongside each other and permitting strip to pass between them from an entry side to an exit side, and comprising roll actuating means for adjusting the position of the rolls, wherein the system comprises at least one camera means for viewing the strip on the entry side of the mill and measuring the axial alignment thereof to produce a camera measurement signal which is used as an input signal to control the roll actuating means which acts on the roll to adjust the roll gap and/or tilt angle of the roll. First and second camera means are provided for viewing the strip on the exit and entry sides of the mill. A pair of actuating means are provided one arranged on each side of the rolls. The actuating means may be hydraulic roll gap cylinders. The center line deviation of the strip is measured by a CCD camera or a similar device, using signal processing to provide a measurement and image of the width of the strip and an error signal is then passed through a control system which generates a differential roll gap correction.
