Abstract

Die Erfindung betrifft ein Verfahren zur Regelung der Auslaufdicke ha eines gewalzten Bandes stromab eines Walzgerüstes (1, 5.1, 5.2, 5.3 ... 5.n), wobei eine Sollwertabweichung Δha der Auslaufdicke ha als Führungsgröße eine Stellgröße beaufschlagt. Um insbesondere in der Beschleunigungs- bzw. Verzögerungsphase der Walzstraße auf einfache Weise eine geforderte Auslaufdicke ha sicherzustellen, ist vorgesehen, daß als Stellgröße der Reibungskoeffizient µ zwischen Walzgerüst (1, 5.1, 5.2, 5.3 ... 5.n) und gewalztem Band vorgesehen ist.
