Description

Die Erfindung betrifft ein / 4-Rollen- / 6-Rollen /18-HS Rollenwalzgerüst in Kassettenbauweise.The invention relates to a / 4-Rollen- / 6-Rollen / 18-HS roll rolling mill in cassette construction.

Aus der WO 2004/052568 A1 ist ein 4-Rollen-/6-Rollen-/18 Rollenwalzgerüst in Kassettenbauweise bekannt, bei dem die Biegekraft über Kolben-Zylinder-Einheiten, die mit Mae West Blöcken verbunden sind, auf die Biegezapfen der Walzeneinbaustücke übertragen wird.From the WO 2004/052568 A1 There is known a 4-roll / 6-roll / 18 roll mill in a cassette construction in which the bending force is transmitted via piston-cylinder units, which are connected to Mae West blocks, on the bending pins of the roll chocks.

Vorbekannte 4-high, 6-high, 18 HS Walzgerüste in Kassettenbauweise, haben keine Kombinationsmöglichkeit der unterschiedlichen Betriebsarten, wie CVC plus® 4-High bzw. 6-high als auch CVC plus® 18 HS.Previously known 4-high, 6-high, 18 HS rolling stands in cassette construction, have no possibility of combining different operating modes, such as CVC plus® 4-High or 6-high and CVC plus® 18 HS.

Ein Wesentlicher Anspruch an ein kombiniertes Walzgerüst besteht darin, während eines üblichen Walzenwechsels zwischen den beiden Betriebsarten wechseln zu können, ohne Umbauaktionen am Gerüst vorzunehmen zu müssen.An essential requirement of a combined rolling stand is to be able to change between the two operating modes during a conventional roll change, without having to make alterations to the framework.

Aufgabe der Erfindung ist es daher, mit unterschiedlichen Betriebsarten und Walzendurchmessern in einem Walzgerüst bei Minimierung der Umrüstzeiten walzen zu können und dementsprechend die Jahresproduktion zu steigern.The object of the invention is therefore to be able to roll with different operating modes and roll diameters in a roll stand while minimizing the changeover times and accordingly to increase the annual production.

Gelöst wird diese Aufgabe erfindungsgemäß bei einem 4-Rollen- / 6- Rollen- /18-HS Rollenwalzgerüst in Kassettenbauweise, bei dem die Biegekraft über Kolben-Zylinder-Einheiten, die mit Mae West Blöcken verbunden sind, auf die Biegezapfen der Walzeneinbaustücke übertragen wird, dadurch, dass der Kolben an der Kolbenstange mit dem Mae West Block fest verbunden ist und
dass die Zylinderkörper die Biegezapfen an den Einbaustücken der Walzen umfassen, so dass damit die Biegekraft direkt auf die Biegezapfen der Walzeneinbaustücke übertragbar ist.This object is achieved according to the invention in a 4-roller / 6-roller / 18-HS roller rolling mill in cassette construction, in which the bending force is transmitted via piston-cylinder units, which are connected to Mae West blocks, on the bending pins of the roll chocks , in that the piston is firmly connected to the piston rod with the Mae West Block and
in that the cylinder bodies comprise the bending pins on the chocks of the rollers, so that the bending force can be transmitted directly to the bending pins of the roller chocks.

Vorzugsweise sind die Kolbenstange des Biegezylinders der oberen Walze und die Kolbenstange der unteren Walze aus einem Stück gefertigt.Preferably, the piston rod of the upper cylinder bending cylinder and the lower roller piston rod are made in one piece.

Nach einer weiteren Ausgestaltung ist vorgesehen, dass die Versorgung mit Hydraulik für die Kolben- als auch die Ringseiten durch die Kolbenstange erfolgtAccording to a further embodiment, it is provided that the supply of hydraulic for the piston as well as the ring sides is effected by the piston rod

Das kombinierte Walzgerüst soll sowohl als Reduktionsgerüst, als auch als Dressierwalzwerk, sowie für Normalstahl, hochfeste Stähle, Edelstähle und NE Metalle zum Einsatz kommen.
Die Arbeitswalzensätze des 4-high / 6-high Gerüstes können gegen die Zwischenwalzensätze in Kassettenbauweise (inkl. seitlichen Stützrollen) und die Arbeitswalzen des 18 HS Gerüstes ausgetauscht werden,The combined rolling stand is to be used both as a reduction stand and as a temper rolling mill, as well as for normal steel, high-strength steels, stainless steels and non-ferrous metals.
The work roll sets of the 4-high / 6-high stand can be exchanged for the intermediate roll sets in cassette construction (including side support rolls) and the work rolls of the 18 HS stand.

Die Wechselposition der Arbeitswalzensätze im 4-high / 6-high Gerüst ist identisch mit der Wechselposition der Zwischenwalzensätze im 18 HS Gerüst.The change position of the work roll sets in the 4-high / 6-high stand is identical to the change position of the intermediate roll sets in the 18 HS stand.

Für beide Betriebsarten werden dieselben Axialverschiebezylinder als auch Biegezylinder verwendet. Zur Abdeckung beider Betriebsarten und den entsprechenden Walzendurchmesserkonfigurationen als auch der gemeinsamen Walzenwechselposition werden große Hübe für die Biegezylinder erforderlich, mit begrenztem Platzangebot bei minimalen Walzendurchmessern im 4-Rollen / 6-Rollen Walzgerüst.For both modes, the same Axialverschiebezylinder be used as well as bending cylinder. To cover both modes and the corresponding roll diameter configurations as well as the common roll change position, large strokes are required for the bending cylinders, with limited space available at minimum roll diameters in the 4-roll / 6-roll mill stand.

In bekannten Konstruktionen für Biegezylinder sind die Zylinderkörper fest in Mae West Blöcken montiert und die Biegekraft wird über die Kolbenstangen und einem geführten Zwischenstück auf die Biegezapfen der Walzeneinbaustücke übertragen.In known designs for bending cylinders, the cylinder bodies are fixedly mounted in Mae West blocks and the bending force is transmitted via the piston rods and a guided intermediate piece on the bending pins of the roll chocks.

Das erfindungsgemäße Biegekonzept besteht darin, dass der Kolben an der Kolbenstange mit dem Mae West Block fest verbunden ist, also der Zylinderkörper verschoben wird.The bending concept according to the invention consists in that the piston is firmly connected to the piston rod with the Mae West Block, that is, the cylinder body is displaced.

Die beweglichen Zylinderkörper werden nach oben bzw. nach unten gedrückt. Die Zylinderkörper sind so ausgeführt, dass sie die Biegezapfen an den Einbaustücken der Walzen umfassen und damit die Biegekraft direkt auf die Biegezapfen der
Walzeneinbaustücke übertragen wird.The movable cylinder bodies are pushed upwards or downwards. The cylinder bodies are designed so that they comprise the bending pins on the chocks of the rollers and thus the bending force directly on the bending pins of the
Roll chocks is transferred.

Die Kolbenstange des Biegezylinders der oberen Walze und die Kolbenstange des Biegezylinder der untere Walze werden aus einem Stück gefertigt.
Die Versorgung mit Hydraulik für die Kolben- als auch die Ringseiten erfolgt durch die Kolbenstange.The piston rod of the bending cylinder of the upper roller and the piston rod of the bending cylinder of the lower roller are manufactured in one piece.
The hydraulic supply for the piston as well as the ring sides is provided by the piston rod.

Dieses Biegekonzept erlaubt große Hübe bei einer kompakten Bauweise, ideal für den Einsatz in kombinierten Walzgerüsten. Dadurch können sowohl die Arbeitswalzen im 4 Rollen bzw. 6 Rollen Walzgerüst als auch die Zwischenwalzen im 18 HS Walzgerüst für den Walzenwechsel auf die benötigte Höhe angehoben bzw. abgesenkt werden, und dann als kompletter Satz mit demselben Wagen getauscht werden. Durch die Kassettenbauweise der Walzensätze wird die Wechseldauer zwischen den Betriebsarten auf die Dauer eines normalen Walzenwechsels reduziert.This bending concept allows large strokes in a compact design, ideal for use in combined rolling stands. As a result, both the work rolls in the 4-roll or 6-roll rolling mill and the intermediate rolls in the 18 HS mill stand for the roll change can be raised or lowered to the required height, and then exchanged as a complete set with the same car. Due to the cassette construction of the sets of rollers, the changeover time between the modes is reduced to the duration of a normal roll change.

Erst durch dieses Biegekonzept ist es möglich ein Walzgerüst für die beiden Betriebsarten - sowohl CVC plus® 4-high bzw. 6-high als auch CVC plus® 18 HS in Kassettenbauweise zu realisieren.Only with this bending concept is it possible to realize a roll stand for the two operating modes - both CVC plus® 4-high or 6-high and CVC plus® 18 HS in cassette construction.

Die Erfindung soll nachfolgend mit Bezug auf die Zeichnungen näher erläutert werden.
Dabei zeigt: Fig. 1.a. schematisch ein Walzgerüst in 18 HS Konfiguration Fig. 1.b. schematisch ein Walzgerüst in 4-high Konfiguration Fig. 1.c. schematisch ein Walzgerüst in 6-high Konfiguration The invention will be explained in more detail with reference to the drawings.

Die Kolbenstangen 1 werden mittels eines Halteklotzes 2 in Mae West Blöcken 3 fest gehalten. Die Zylindergehäuse 4 werden durch Druckbeaufschlagung der Kolben- bzw. Ringseite in Führungen in den Mae-West Blöcken 3 vertikal verfahren, und übertragen mittels der Taschen 5 im Zylinderkörper 4 die Biegekräfte über die Biegezapfen 6 an den Walzen-Einbaustücken 7 auf diese, und dementsprechend auf die Walzenzapfen der Zwischenwalze 8 im 18 HS Walzgerüst (Fig. 1a) bzw. der Arbeitswalze 9 im 4-Rollen Walzgerüst (Fig. 1b) oder 10 im 6-high Walzengerüst (Fig. 1c).The piston rods 1 are held firmly by means of a holding block 2 in Mae West blocks 3. The cylinder housing 4 are moved vertically by pressurizing the piston or ring side in guides in the Mae-West blocks 3, and transmitted by means of the pockets 5 in the cylinder body 4, the bending forces on the bending pin 6 on the roll chocks 7 on this, and accordingly on the roll necks of the intermediate roll 8 in the 18 HS rolling stand ( Fig. 1a ) or the work roll 9 in 4-roll rolling stand ( Fig. 1b ) or 10 in the 6-high mill stand ( Fig. 1c ).
