Abstract

Eine Vorrichtung (1) und ein Verfahren zur Beeinflussung der Reibungsverhältnisse zwischen, jeweils der oberen und der unteren Walze (6, 7) in Walzgerüste (26) von Warmbreitband- oder Kaltbandstraßen. Die Vorrichtung besteht aus einer Sprüheinrichtung (2), die an der Einlaufseite (27) des jeweiligen Walzgerüstes (28) angeordnet ist. Diese sprüht eine definierte Menge Flüssigkeit in Richtung des Walzspaltes. Eine Regeleinrichtung (3) ist zur Bestimmung der Menge und der Abgabe dieser Flüssigkeit vorgesehen. Wobei als Regelgröße eine vorher ermittelte oder eine errechnete Größe in Verbindung mit dem Meßwert des tatsächlichen Drehmoments der unteren und der oberen Walze verwendet wird.

Figure 00000001
A device (1) and a method for influencing the frictional relationships between the respective upper and lower rolls (6, 7) in roll stands (26) of hot wide strip or cold strip lines. The device consists of a spray device (2) which is arranged on the inlet side (27) of the respective roll stand (28). This sprays a defined amount of liquid in the direction of the roll gap. A control device (3) is provided for determining the quantity and the dispensing of this liquid. The control variable used is a previously determined or a calculated variable in connection with the measured value of the actual torque of the lower and the upper roller.
