Abstract
Description
Die Erfindung betrifft ein Walzwerk, insbesondere ein Schräg- oder Diescherwalzwerk, in Modulbauweise, mit in einem Walzgerüst drehgelagerten Walzen, wobei der Walzgerüstrahmen aus Gussständern, geschweißten Blechständern oder aus Schmiedeständern gebildet ist, die auf im Fundament verankerten und vergossenen Sohlplatten befestigt sind.The invention relates to a rolling mill, in particular a diagonal or Diescherwalzwerk, in modular design, with rotatably mounted in a roll stand rollers, the Rolltooth is formed from Gussständern, welded sheet metal stands or forging stands, which are mounted on anchored in the foundation and cast sole plates.
Für Walzwerke sind die Gerüstständer der bekannten Bauart als Einheit in der Herstellung und für die Handhabung unangemessen groß. Ein Gerüstständer ist als einteilige Gusseinheit in der Herstellung schwierig und teuer. Die vorhandenen Krankapazitäten, die Handhabung und die Bearbeitung setzen für die Ständergrößen Grenzen. Es ist daher dazu übergegangen worden, die Walzwerksständer in Modulbauweise herzustellen, um kleinere Einheiten leichter handhaben zu können. Außerdem spielen die Kräfteverhältnisse zwischen den im Walzprozess entstehenden Kräften und der Ausbildung des Walzgerüstrahmens eine Rolle.For rolling mills, the framework stands of the known type are unreasonably large as a unit in manufacturing and handling. A scaffold stand is difficult and expensive to manufacture as a one-piece casting unit. The existing crane capacities, handling and processing set limits for the stator sizes. It has therefore begun to produce the rolling mill stands in modular design to handle smaller units easier. In addition, the balance of power between the resulting forces in the rolling process and the formation of Walzgerüstrahmens play a role.
Der Erfindung liegt die Aufgabe zugrunde, Herstellung, Handhabung und Ausbildung des Walzgerüstrahmens dahingehend zu vereinfachen, dass die Herstellung leichter und wirtschaftlicher erfolgen kann, dass die Handhabung durch geringere Gewichte erleichtert wird und dass die konstruktive Ausbildung in Abhängigkeit der Walzprozesskräfte erfolgt.The invention has for its object to simplify the production, handling and training of Walzgerüstrahmens to the effect that the production can be made easier and more economical, that the handling is facilitated by lower weights and that the structural design depending on the rolling process forces.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Walzgerüstrahmen aus sich gegenüberliegenden, auf der Sohlplatte befestigten Portalrahmen mit einer den Abstand zwischen den Portalrahmen bildenden oberen Kassette für eine obere Walzeneinheit und einer unteren Kassette für die untere Walzeneinheit zusammensetzbar ist, wobei die beiden Portalrahmen mittels mehrerer, übereinander und / oder nebeneinander angeordneter Zugelemente miteinander verspannbar und fixiert sind. Diese Gerüstständer-Bauweise vereinfacht den Ständer-Aufbau und führt zu leichteren, besser handhabbaren Moduleinheiten, die wirtschaftlich herstellbar sind. Die Modulbauweise mit nur vier Modulgruppen, von denen jeweils zwei gleich oder sehr ähnlich sind, gestattet eine wirtschaftlich besser überschaubare Konstruktion und Herstellung und bezüglich der Walzprozesskräfte eine Zentralisierung der auf den Ständer wirkenden Kräfte. Außerdem ergeben sich Vorteile durch eine belastungsoptimierte Massenverteilung, so dass keine überlagerten Spannungszustände entstehen. Anläßlich von FEM-Untersuchungen wurde eine hohe Steifigkeit des Gerüstständers festgestellt, die die Produktqualität erhöht. Weiterhin ermöglicht eine derartige modulare Bauweise eine beliebige Baugrößenkette. Die Bauweise ist um ca. 15% kostengünstiger, weil sich der Kreis der Materialanbieter, z.B. für Guss- oder Schmiedeteile, erweitert. Die Flexibilität der eigenen Fertigung und des Fertigungszukaufs kann dadurch gesteigert werden. Die einfachere Fertigung führt zu kürzeren Lieferzeiten. Dabei entfallen bisherige Probleme der Materialauswahl, ob Schmiedeteil oder hochwertige Bleche als Ausgangsmaterial dienen.
Ferner wird die Dehnkraft aus dem Walzprozess von den beiden Portalrahmen aufgenommen und über die Sohlplatte direkt in das Fundament weitergeleitet. Andere von dem Walzprozess bewirkte Kräfte werden von den Kassetten aufgenommen und in sich kurzgeschlossen.The object is achieved according to the invention that the Walzgerüstrahmen from opposite, fixed to the base plate portal frame with a distance between the portal frame forming upper cassette for an upper roller unit and a lower cassette for the lower roller unit is assembled, the two portal frame means several, one above the other and / or juxtaposed tension elements are braced and fixed together. This framework stand construction simplifies the stand construction and leads to lighter, more manageable modular units that can be produced economically. The modular design with only four module groups, two of which are the same or very similar, allows a more economically manageable design and manufacturing and with respect to the rolling process forces a centralization of the forces acting on the stand forces. In addition, advantages result from a load-optimized mass distribution, so that no superimposed voltage states arise. On the occasion of FEM investigations, a high rigidity of the scaffold stand was found, which increases the product quality. Furthermore, such a modular design allows any size chain. The construction method is about 15% cheaper, because the circle of material suppliers, eg for castings or forgings, expands. The flexibility of the own production and the acquisition of purchase can be increased thereby. The simpler production leads to shorter delivery times. This eliminates previous problems of material selection, whether forged or high quality sheets serve as the starting material.
Furthermore, the stretching force from the rolling process is taken up by the two portal frames and forwarded via the sole plate directly into the foundation. Other forces caused by the rolling process are absorbed by the cassettes and short-circuited.
Eine Ausgestaltung sieht vor, dass die beiden Portalrahmen unten mit einem unteren Querrahmen miteinander verbunden sind.An embodiment provides that the two portal frame are connected to each other below with a lower transverse frame.
Ein vorteilhafter Abschluss nach oben ergibt sich dadurch, dass ein Querhaupt für den Walzenausbau oder für den Walzeneinbau zwischen den Portalrahmen in oberen Führungen parallel verschiebbar ist. Der untere Querrahmen und das Querhaupt geben die auftretenden Walzkräfte vertikal an die Portalrahmen weiter.An advantageous conclusion upwards results from the fact that a crosshead for roll removal or for roll installation between the portal frame in upper guides is displaced parallel. The lower transverse frame and the crosshead give the rolling forces occurring vertically to the portal frame on.
Für eine Art von Schrägwalzwerken ist es vorteilhaft, dass die Walzen aus jeweils einer unteren Trommeleinheit und einer oberen Trommeleinheit mit Kegelwalzen bestehen. Die Erfindung ist daher sehr zweckmäßig auf Kegelschrägwalzwerke anzuwenden.For one type of skew rolling mills, it is advantageous that the rolls each consist of a lower drum unit and an upper drum unit with tapered rollers. The invention is therefore very useful to apply to cone slanting mills.
Hierzu ist weiter vorgesehen, dass zumindest die Geräte der Vorschubwinkelverstellung und die Walzen-Trommel-Ausbalancierung an den Kassetten befestigt sind.For this purpose, it is further provided that at least the devices of the feed angle adjustment and the roller drum balance are attached to the cassettes.
Für die Weiterbildung des Walzwerks zu einem Diescherwalzwerk wird vorgeschlagen, dass den Kegelwalzen zumindest eine Diescherscheibe auf jeweils einem Diescherscheibenschlitten zugeordnet ist, der auf einer quer zur Walzrichtung verlaufenden Gleitbahn aus der Betriebsposition in eine Wechselposition und zurück verfahrbar ist. Bei den herkömmlichen Tonnen- oder Kegelschrägwalzwerken sind die Diescherscheiben in Schwingen an den Längsseiten der Gerüstständer anmontiert. Die schwenkbare Anordnung und die hydraulische Verriegelung am Walzgerüstrahmen führen während des Walzvorgangs zum "Atmen" der Schwingen, was sich auf die Walzgutqualität negativ auswirken kann. Ferner geht durch die bekannten Schwingen Freiraum beiderseits des Walzgerüstrahmens durch den Schwenkweg der Schwingen verloren, der besser anderweitig zu nutzen wäre. Die auf die Diescherscheiben wirkenden Walzkräfte werden außerdem durch hydraulisch betätigte Verriegelungen vom Walzgerüstständer aufgenommen und führen zu zusätzlichen Belastungen der Gerüstständer.For the development of the rolling mill to a Diescherwalzwerk is proposed that the tapered rollers at least one Diescherscheibe is assigned to each one Diescherscheibenschlitten which is movable on a transverse to the rolling direction slide from the operating position to a change position and back. In the conventional barrel or cone rolling mills the Diescherscheiben are mounted in wings on the long sides of the frame stand. The swiveling arrangement and the hydraulic locking on the rolling mill frame lead to "breathing" of the wings during the rolling process, which can have a negative effect on the rolling stock quality. Furthermore, lost by the known swing free space on both sides of the Walzgerüstrahmens by the pivoting of the wings, which would be better to use otherwise. The forces acting on the Diescherscheiben rolling forces are also absorbed by hydraulically actuated locks from the roll stand and lead to additional loads on the framework stands.
Eine weitere Besonderheit ergibt sich noch daraus, dass der Diescherscheibenschlitten mittels einer Kniehebel-Verriegelung auf der Gleitbahn festsetzbar ist. Dadurch werden die Positionen im Betrieb und während des Wechselns der Diescherscheibe genau und sicher eingehalten.Another peculiarity arises from the fact that the Diescherscheibenschlitten can be fixed by means of a toggle lever lock on the slide. As a result, the positions are maintained accurately and safely during operation and while changing the Diescherscheibe.
Eine andere Verbesserung besteht darin, dass der Diescherscheibenschlitten an einer an der unteren Kassette befestigten, räumlich gestellten Aufnahme zentriert ist.Another improvement is that the die disc carriage is centered on a spatially mounted receptacle attached to the lower cassette.
An und für sich werden für den Antrieb der Walzen ausrückbare Gelenkwellen eingesetzt, wie eine solche z.B. in der DE 43 32 893 C1 beschrieben ist. Zur weiteren Einsparung an Bauraum wird jedoch vorgeschlagen, dass die Antriebskraft auf die Walzen im Walzgerüstrahmen jeweils mittels einer ausrückbaren Gelenkwelle übertragbar ist, in deren Schnellverschlusskupplung in dem walzenseitigen Treffer eine hydraulisch betätigbare Klemmung vorgesehen ist. Dadurch wird an Länge gespart, was dem Einbauraum zugute kommt.In and of itself, disengageable propeller shafts are used for driving the rollers, such as e.g. is described in DE 43 32 893 C1. For further savings in space, however, it is proposed that the driving force can be transmitted to the rollers in the rolling stand each by means of a disengageable propeller shaft, in the quick-release coupling in the roller-side hit a hydraulically actuated clamp is provided. This saves on length, which benefits the installation space.
Die Konstruktion und die Herstellung des Walzgerüstrahmens werden durch weitere Funktionen und Einrichtungen beeinflusst. So ist nach zusätzlichen Merkmalen vorgesehen, dass der erforderliche Einbauraum bzw. das Gewicht des Walzgerüstrahmens auf eine minimierte Länge der Walzenachse abgestimmt ist. Somit kann durch Wahl des günstigsten Antriebs ebenfalls an Bauvolumen des Walzgerüstrahmens gespart werden.The design and manufacture of the rolling mill frame are influenced by other functions and facilities. Thus, it is provided according to additional features that the required installation space or the weight of the rolling mill frame is tuned to a minimized length of the roll axis. Thus, by choosing the cheapest drive can also be saved on construction volume of Walzgerüstrahmens.
