Abstract

Die Erfindung betrifft ein Walzwerk, insbesondere ein Warmflachwalzwerk, mit paarweisen Arbeitswalzen, die sich ggf. unmittelbar oder über Zwischenwalzen an ebenfalls paarweisen Stützwalzen abstützen, wobei mindestens die Walzen eines der Walzenpaare gegeneinander axial verschiebbar sind.
Um eine weitgehende Beeinflussung und Kompensation der infolge der thermischen Bombierung und unter Last erfolgenden Durchbiegung der Walzen und der dadurch entstehenden Walzspaltveränderungen zu ermöglichen und somit eine optimale Profil- und Planheitsregelung dieses Walzwerkes zu erreichen, wird erfindungsgemäß vorgeschlagen, daß mindestens jede Walze (1, 2) des verschiebbaren Walzenpaares als Hohlwalze ausgebildet ist, deren Hohlräume (4, 5) bezogen auf die Walzenlängsachse (6) drehsymmetrisch und bezogen auf eine gedachte, die Walzenlängsachse (6) in der Walzballenmitte schneidende Querebene (7) unsymmetrisch ausgebildet sind und beide Walzen (1, 2) des verschiebbaren Walzenpaares mit identisch ausgebildeten Hohlräumen (4, 5) um 180° zueinander gewendet eingebaut sind.

Figure 00000001
The invention relates to a rolling mill, in particular a hot flat rolling mill, with paired work rolls, which may be supported directly or via intermediate rolls on support rolls, also in pairs, at least the rolls of one of the roll pairs being axially displaceable relative to one another.
According to the invention, it is proposed that at least each roller (1, 2.) In order to largely influence and compensate for the deflection of the rollers resulting from the thermal crowning and under load deflection of the rollers and the resulting changes in the roll gap, and thus to achieve optimum profile and flatness control of this rolling mill ) of the displaceable pair of rollers is designed as a hollow roller, the cavities (4, 5) of which are rotationally symmetrical with respect to the longitudinal axis of the roller (6) and asymmetrical with respect to an imaginary transverse plane (7) which intersects the longitudinal axis (6) of the roller center and both rollers ( 1, 2) of the movable pair of rollers with identically designed cavities (4, 5) are installed turned through 180 ° to each other.
