Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Walzen von Bändern (B), welche über ihre Breite eine ungleichförmige Dicken- und/oder Längenverteilung aufweisen, unter Verwendung mindestens einer auf der Einlauf- und/oder Auslaufseite eines Walzwerks (W,W',W'') angeordneten, in ihrer Stellung relativ zum Band (B) verschwenkbaren Steuerrolle (5,9,21,27,41,43), welche es unabhängig von den jeweiligen Betriebszuständen ermöglichen, bei einer geringen Störanfälligkeit ein durch Ungleichförmigkeit im Dicken- und/oder Längenverlauf über die Breite eines Bandes verursachtes Bandverlaufen zu kompensieren. Dies wird erfindungsgemäß dadurch erreicht, daß mit mindestens einer Meßeinrichtung (7,11,25) die Verteilung der Zugspannungen über die Breite des Bandes (B) erfaßt wird und daß entsprechend der erfaßten Zugspannungsverteilung die Steuerrolle (5,9,21,27,41,43) so lange verstellt wird, bis die erfaßte Zugspannungsverteilung einem Sollwert entspricht. The invention relates to a method and a device for rolling strips (B), which have a non-uniform thickness and / or length distribution over their width, using at least one on the inlet and / or outlet side of a rolling mill (W, W ', W '') arranged in their position relative to the belt (B) swiveling control roller (5,9,21,27,41,43), which make it possible, independent of the respective operating conditions, with a low susceptibility to malfunction due to non-uniformity in the thickness and / or to compensate for the course of the length caused by the width of a band. This is achieved according to the invention in that the distribution of the tensile stresses over the width of the belt (B) is recorded with at least one measuring device (7, 11, 25) and that the control roller (5, 9, 21, 27, 41) corresponds to the tensile stress distribution recorded , 43) is adjusted until the detected tension distribution corresponds to a target value.
