Titel: Walzenkühl- und/oder Schmiervorrichtung für Kaltbandwalzwerke, insbesondere FeinbandwalzwerkeTitle: Roll cooling and/or lubricating device for cold strip rolling mills, in particular fine strip rolling mills
Die Erfindung betrifft Walzenkühl- und/oder "Schmiervorrichtungen für Kaltbandwalzwerke, insbesondere . Feinbandwalzwerke, mit über die Bandbreite auf Düsenbalken angeordneten Sprühdüsen, wobei jeder Arbeitswalze mindestens ein Düsenbalken zugeordnet ist, insbesondere zur Regelung der Bandzugspannung über die Bandbreite durch eine Änderung des wirksamen Walzenballendurchmessers und/oder eine Beeinflussung der Walzenschmierung mit einer druck- und/oder mengen- und/oder temperaturgeregelten Zuführung von Walzöl bzw. Emulsionen (DE 34 19 261 C2).The invention relates to roll cooling and/or lubricating devices for cold strip rolling mills, in particular . fine strip rolling mills, with spray nozzles arranged on nozzle bars across the strip width, with each work roll being assigned at least one nozzle bar, in particular for regulating the strip tension across the strip width by changing the effective roll barrel diameter and/or influencing the roll lubrication with a pressure and/or quantity and/or temperature-controlled supply of rolling oil or emulsions (DE 34 19 261 C2).
Bei Walzenkühl- und/oder Schmiervorrichtungen dieser Art für Kaltbandwalzwerke sind die teilweise an die Walzenständer und teilweise an die in den Ständerfenstern eingebauten Hydraulikblöcken angebundenen Düsenbalken mit den Steuerventilen für die Sprühdüsen schwer zugängig, so daß Reparatur- und Wartungsarbeiten an den Düsenbalken umständlich und zeitaufwendig sind.In roll cooling and/or lubrication devices of this type for cold strip rolling mills, the nozzle bars with the control valves for the spray nozzles, which are partly connected to the roll stands and partly to the hydraulic blocks installed in the stand windows, are difficult to access, so that repair and maintenance work on the nozzle bars is cumbersome and time-consuming.
Der Erfindung liegt die Aufgabe zugrunde, die Zugängigkeit der Düsenbalken der gattungsgemäßen Walzenkühl- und Schmiervorrichtungen im Hinblick auf eine Vereinfachung und eine Beschleunigung von notwendigen Reparatur- und Wartungsarbeiten zu verbessern.The invention is based on the object of improving the accessibility of the nozzle bars of the generic roller cooling and lubricating devices with a view to simplifying and accelerating necessary repair and maintenance work.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Walzenkühl- und/oder Schmiervorrichtung mit einer Positioniervorrichtung für die Düsenbalken gemäß Patentanspruch 1.This object is achieved according to the invention by a roller cooling and/or lubricating device with a positioning device for the nozzle bars according to patent claim 1.
Die Unteransprüche beinhalten zweckmäßige Ausgestaltungen der Erfindung.The subclaims contain expedient embodiments of the invention.
Die an die Walzgerüste angebauten Positioniervorrichtungen ermöglichen ein einfaches Verfahren der Düsenbalken aus der Arbeitsposition an den Walzen in eine von diesen entfernte ■•Wartungsposition, in der die Düsenbalken für Reparatur- und Wartungsarbeiten gut zugängig sind.The positioning devices attached to the rolling stands enable the nozzle beams to be easily moved from the working position on the rolls to a maintenance position away from them, in which the nozzle beams are easily accessible for repair and maintenance work.
Die Erfindung ist nachstehend anhand von Zeichnungen einer bei einem Quartowalzgerüst eingesetzten Positioniervorrichtung für die Düsenbalken erläutert. Es zeigt in schematischer DarstellungThe invention is explained below with reference to drawings of a positioning device for the nozzle beams used in a four-high rolling mill. It shows a schematic representation

Das in den Fign. 1 und 2 dargestellte Quartowalzgerüst weist zwei Walzenständer 2 auf, in denen in nicht dargestellten Einbaustücken eine untere und eine obere Arbeitswalze 3, 4 sowie eine untere und eine obere Stützwalze 5, 6 drehbar gelagert sind. Das Walzband 7 wird von einem Abwickelhaspel 8 abgezogen und über eine Bandeinführeinheit 9, die aus einem ersten Luftkissenförderer 10, einem Trennmesser 11, einem zweiten Luftkissenförderer 12 sowie einer Rolleneinheit mit zwei in Bandlaufrichtung a im Abstand voneinander angeordneten Umlenkrollen 13, 14 sowie einer zwischen diesen angeordneten, mit einem dritten Luftkissenförderer 15 kombinierten Spannrolle 16 besteht, in den Walzspalt 17 gefördert. Die Bandeinführeinheit 9 ist auf einem Maschinengestell 18 angeordnet, das in Bandlaufrichtung a vor- und entgegen der Bandlaufrichtung in Pfeilrichtung b zurückfahrbar ist.The four-high rolling mill shown in Figs. 1 and 2 has two roll stands 2 in which a lower and an upper working roll 3, 4 as well as a lower and an upper support roll 5, 6 are rotatably mounted in chocks not shown. The rolled strip 7 is drawn off from an uncoiler 8 and conveyed into the roll gap 17 via a strip feed unit 9, which consists of a first air cushion conveyor 10, a cutting knife 11, a second air cushion conveyor 12 and a roller unit with two deflection rollers 13, 14 arranged at a distance from one another in the strip running direction a and a tension roller 16 arranged between them and combined with a third air cushion conveyor 15. The strip feeding unit 9 is arranged on a machine frame 18 which can be moved forwards in the strip running direction a and backwards against the strip running direction in the direction of arrow b.
