DEVICE AND METHOD FOR ROLLING A METAL STRIP

A device and a method for rolling a metal strip. A distance of the upper/lower backup roll at at least one point thereof from a predetermined upper/lower reference point is measured by an upper/lower sensor and the measured values of the sensors are sent to a control device. A strain of the roll sta...

Zusammenfassung:A device and a method for rolling a metal strip. A distance of the upper/lower backup roll at at least one point thereof from a predetermined upper/lower reference point is measured by an upper/lower sensor and the measured values of the sensors are sent to a control device. A strain of the roll stand is calculated using a mathematical model, taking into account the rolling force generated. By the control device, an absolute value of the roll gap and thus the resulting thickness of the rolling stock is determined by the control device on the basis of the measured positions of the backup rolls and the calculated strain of the roll stand.
