Abstract (en)

A flexible strip rolling mill stand, with four independently axially displaceable back-up rolls (5-8), is new. A multi-roll strip rolling mill stand, used for flexible rolling, has four back-up rolls (5-8) which can be independently axially displaced relative to one another by the same or different distances from the vertical central plane of the stand (1) for equalization of roll set bending and for adaptation to the strip width.

Abstract (de)

Das Walzgerüst (1) ist zum flexiblen Walzen von Bandmaterial (2) bestimmt. Die untere und die obere Arbeitswalze (3,4) des Walzgerüstes (1) sind in zwei unteren und zwei oberen angetriebenen Stützwalzen (5,6; 7,8) gelagert, die symmetrisch zur senkrechten Walzenachsenebene (9-9) der Arbeitswalzen (3,4) angeordnet und paarweise (5,6; 7,8) in unteren und oberen Stützwalzeneinbaustücken (10,11) in Lagereinheiten (10a, 10b, 11a, 11b) in Achsrichtung verschiebbar gelagert sind. Die vier Stützwalzen (5,6,7,8) sind zum Ausgleich der auftretenden Walzensatzdurchbiegung und zur Anpassung an die Bandbreite um gleiche und unterschiedliche Strecken unabhängig voneinander zur senkrechten Mittelebene des Walzgerüstes (1) gegensinnig axial verschiebbar. <IMAGE>
