Abstract

Ein Walzgut (1) wird in einer Transportrichtung (x) von einem vorderen zu einem hinteren Walzgerüst (2, 3) transportiert. Das Walzgut (1) führt dabei zwischen den Walzgerüsten (2, 3) eine Schwingung quer zur Transportrichtung (x) aus. Mindestens eine charakteristische Eigenschaft (A, f) der Schwingung wird quantitativ erfaßt und daraus ein im Walzgut (1) zwischen den Walzgerüsten (2, 3) herrschender Zug (Z) bzw. Druck ermittelt. Eines der Walzgerüste (2, 3) wird derart nachgeregelt, daß sich im Walzgut (1) zwischen den Walzgerüsten (2, 3) ein Sollzug (Z*) aufbaut.

Figure 00000001
A rolling stock (1) is transported in a transport direction (x) from a front to a rear rolling stand (2, 3). The rolling stock (1) executes an oscillation between the rolling stands (2, 3) transversely to the transport direction (x). At least one characteristic property (A, f) of the vibration is recorded quantitatively and a tension (Z) or pressure prevailing in the rolling stock (1) between the roll stands (2, 3) is determined therefrom. One of the roll stands (2, 3) is readjusted in such a way that a target tension (Z *) builds up in the rolling stock (1) between the roll stands (2, 3).
