Claims (6)

1. Mehrwalzengerüst zum Walzen von bandförmigem Walzgut, mit einer unteren und einer oberen Arbeitswalze, den Arbeitswalzen zugeordneten Stützwalzen, Walzenbiegeeinrichtungen für die Arbeitswalzen sowie Einrichtungen zum Anstellen und Ausbalancieren der Stützwalzen, dadurch gekennzeichnet, daß die untere und die obere Arbeitswalze (3, 4) des Walzgerüstes (1) zum Walzen von dickenprofiliertem Bandmaterial (2) in zwei unteren und zwei oberen angetriebenen Stützwalzen (5, 6; 7, 8) gelagert sind, 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) gelagert sind, und daß die beiden Stützwalzenpaare (5, 6; 7, 8) zum Ausgleich der auftretenden Walzensatzdurchbiegung und zur Anpassung an die Bandbreite (22) um gleiche oder unterschiedliche Strecken (S) zur senkrechten Mittelebene (23-23) des Walzgerüstes (1) gegensinnig axial verschiebbar sind.1. Multi-roll stand for rolling strip-shaped rolling stock, with a lower and an upper work roll, support rolls assigned to the work rolls, roll bending devices for the work rolls and devices for adjusting and balancing the support rolls, characterized in that the lower and the upper work rolls ( 3 , 4 ) of the roll stand ( 1 ) for rolling thick-profiled strip material ( 2 ) are mounted in two lower and two upper driven support rolls ( 5 , 6 ; 7 , 8 ), which are symmetrical to the vertical roll axis plane ( 9-9 ) of the work rolls ( 3 , 4 ) arranged in pairs (5, 6; 7, 8) are mounted in lower and upper support roll chocks (10, 11), and that the two support roller pairs (5, 6; 7, 8) for balancing the roll set bending occurring and to adapt to bandwidth ( 22 ) the same or different distances (S) to the vertical central plane ( 23-23 ) of the roll stand ( 1 ) in opposite directions axi are displaceable. 2. Mehrwalzengerüst nach Anspruch 1, dadurch gekennzeichnet, daß der Druck der durch ein Druckmittel betätigten Arbeitswalzenbiegeeinrichtungen (17, 18) zwischen einem unteren Druckwert zum Ausbalancieren der Arbeitswalzen (3, 4) und zum schlupfverhindernden Anpressen derselben gegen die Stützwalzen (5, 6; 7, 8) und einem als positive Biegekraft wirkenden oberen Druckwert einstellbar ist.2. Multi-roll stand according to claim 1, characterized in that the pressure of the work roll bending devices ( 17 , 18 ) actuated by a pressure medium between a lower pressure value for balancing the work rolls ( 3 , 4 ) and for preventing the latter from slipping against the support rolls ( 5 , 6 ; 7 , 8 ) and an upper pressure value acting as a positive bending force is adjustable. 3. Mehrwalzengerüst nach Anspruch 1 und 2, gekennzeichnet durch eine Regelung der Arbeitswalzenbiegeeinrichtungen (17, 18) in Abhängigkeit von der Walzkraft (F). 3. Multi-roll stand according to claim 1 and 2, characterized by a regulation of the work roll bending devices ( 17 , 18 ) as a function of the rolling force (F). 4. Mehrwalzengerüst nach einem der Ansprüche 1 bis 3, gekennzeichnet durch eine Regelung der Arbeitswalzenbiegeeinrichtungen (17, 18) in Abhängigkeit von der Bandbreite (22).4. Multi-roll stand according to one of claims 1 to 3, characterized by a regulation of the work roll bending devices ( 17 , 18 ) as a function of the bandwidth ( 22 ). 5. Mehrwalzengerüst nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Ausbalanciereinrichtungen (19, 20) für die Stützwalzen (5, 6; 7, 8) auf die Stützwalzeneinbaustücke (10, 11) wirkende Stellzylinder mit Speichereinheiten zur laufenden Änderung der Anstellungsposition der Stützwalzen (5, 6; 7, 8) aufweisen.5. Multi-roll stand according to one of claims 1 to 4, characterized in that the balancing devices ( 19 , 20 ) for the support rollers ( 5 , 6 ; 7 , 8 ) on the support roller chocks ( 10 , 11 ) acting actuating cylinders with storage units for the continuous change of Have position of the support rollers ( 5 , 6 ; 7 , 8 ). 6. Mehrwalzengerüst nach einem der Ansprüche 1 bis 5, gekennzeichnet durch an den Stützwalzeneinbaustücken (10, 11) angebrachte Antriebsmotoren (14) für die Stützwalzen (5, 6; 7, 8)6. Multi-roll stand according to one of claims 1 to 5, characterized by drive motors ( 14 ) attached to the support roll chocks ( 10 , 11 ) for the support rolls ( 5 , 6 ; 7 , 8 )
