Description

Die Erfindung betrifft ein Walzwerk zum Warmwalzen von Metall, insbesondere von Aluminium, mit einer Warmbandstraße mit einer Vorwalzstraße und einer Fertigwalzstraße sowie ein entsprechendes Warmwalzverfahren. Eine Vorrichtung sowie ein Verfahren gemäß den Oberbegriffen der Ansprüche 1 bzw. 4 sind aus US-A-5 931 040 bekannt.The invention relates to a rolling mill for hot rolling of metal, in particular of aluminum, with a hot strip mill with a roughing mill and a finishing train and a corresponding hot rolling process. An apparatus and a method according to the preambles of claims 1 and 4 are made US-A-5,931,040 known.

Es ist bekannt, Aluminium in Warmbandstraßen auszuwalzen. Das klassische bzw. herkömmliche Layout 100 für ein solches Warmwalzwerk, das beispielhaft mit Fig. 3 dargestellt ist, setzt sich aus den wesentlichen Bearbeitungsstationen Ofenbereich 102, Walzstraße 103 und ggf. Zurichtung (Adjustage) zusammen.It is known to roll aluminum in hot strip mills. The classic or conventional layout 100 for such a hot rolling mill, the exemplary with Fig. 3 is composed of the essential processing stations furnace area 102, rolling mill 103 and possibly finishing (finishing) together.

Ein Aluminium-Barren 117 wird in Öfen 120, 121 - beispielsweise Herd- oder Stoßöfen - auf Walztemperatur gebracht und in dem eingerüstigen Vorwalzgerüst 108 der Vorwalzstraße 104 nach Durchlaufen eines Stauchgerüstes 107 vorgewalzt. Während des Vorwalzens wird das Vorwalzprodukt mit einer ersten Schere 122 zwischen geschopft. Vor dem Einlauf in die Fertigwalzstraße, die sich - wie hier nur beispielhaft gezeigt - aus vier Gerüsten 111, 112, 123, 124 zusammensetzt, wird die Platine 119 am Platinenende und -anfang geschopft, wobei zwischen diesen beiden Schopfscheren 122, 125 ein bestimmter Abstand vorliegt. Das in der Fertigwalzstraße fertig gewalzte Band 113 läuft entlang von Besäumscheren 126 und wird über Treiberrollen 127 von einer Haspeleinrichtung 114 aufgecoilt.An aluminum ingot 117 is brought to rolling temperature in furnaces 120, 121-for example hearth or pusher furnaces-and pre-rolled in the single-stand roughing stand 108 of the roughing train 104 after passing through an upsetting stand 107. During pre-rolling, the rough-rolling product is interspersed with a first scissors 122. Before the entry into the finishing train, which - as shown here only by way of example - composed of four scaffolds 111, 112, 123, 124, the board 119 is pimped at the end and end of the board, between these two cropping shears 122, 125 a certain distance is present. The finish-rolled strip 113 in the finish rolling mill runs along edgers 126 and is reeled up by means of drive rollers 127 from a reeling device 114.

Eine solche Anlage mit Ofenbereich 102 und Walzstraßen 103 kann enorme Baulängen aufweisen. So kann die Länge x eines Ofenbereiches 102 beispielsweise 130 m sein und der Abstand zwischen dem Vorwalzgerüst 108 und dem ersten Gerüst 111 der Fertigwalzstraße beispielsweise 240 m, wobei die Abstände die erzielbaren Coilgrößen beeinflussen. Hierbei erfolgt der Durchlauf des Walzgutes durch die Walzwerksanlage mit Hilfe umfangreicher Transport- und Führungseinrichtungen, wie Rollgänge. Tendenziell arbeiten derartige Walzanlagen wirtschaftlicher mit größeren Coilabmessungen.Such a plant with furnace area 102 and rolling mills 103 can have enormous lengths. For example, the length x of a furnace area 102 may be 130 m, and the distance between the roughing stand 108 and the first stand 111 of the finishing train may be 240 m, for example, the distances influencing the achievable coil sizes. Here, the run takes place of the rolling stock through the rolling mill plant with the help of extensive transport and leadership facilities, such as roller tables. Such rolling mills tend to work more economically with larger coil dimensions.

Anlagen von derartigen Baulängen sind mit hohen Investitionen verbunden und benötigen viel Baufläche. Des weiteren sind die weitläufigen Rollgänge zum Transport des Walzguts ebenfalls investitionsreich.Systems of such lengths are associated with high investment and require a lot of construction space. Furthermore, the extensive roller tables for transporting the rolling stock are also rich in investment.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein von seiner Bauweise kompakteres Walzwerk zum Warmwalzen von Metall, insbesondere von Aluminium, zu schaffen, wobei die Transportzwischenräume zwischen den einzelnen Bearbeitungsstationen (Ofenbereich, Vorwalzen, Fertigwalzen) reduziert sind. Gleichzeitig soll ein Warmwalzverfahren geschaffen werden, das ein Walzen von Band auf Endwalzdicke bei kompakter Bauweise des Walzwerks mit hoher Wirtschaftlichkeit erlaubt.Proceeding from this, the present invention seeks to provide a more compact in its design mill for hot rolling of metal, especially aluminum, with the transport spaces between the individual processing stations (furnace area, roughing, finish rolling) are reduced. At the same time, a hot rolling process is to be created which allows rolling from strip to final roll thickness with a compact design of the rolling mill with high efficiency.

Diese Aufgabe wird durch ein Walzwerk mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 4 gelöst. Vorteilhafte Weiterentwicklungen sind in den Unteransprüchen beschrieben.This object is achieved by a rolling mill with the features of claim 1 and a method having the features of claim 4. Advantageous developments are described in the subclaims.

Grundgedanke der Erfindung ist, dass der kompakte Aufbau des Walzwerks bzw. der Warmbandstraße durch die konsequente Nutzung von Tandemwalzungen in der Vorwalzstraße, in der Fertigstraße oder in der Vorwalzstraße und Fertigwalzstraße gemeinsam entsteht. Die Vorwalzstraße alleine und/oder die Fertigwalzstraße alleine oder die Vorwalz- und Fertigstraße gemeinsam sind Tandemstraßen, d. h. Anlagebereiche, bei der die Walzgerüste hintereinander (Tandem-Anordnung) stehen. Aufgrund des dadurch entstehenden kompakten Baus können erhebliche Teile der sonst notwendigen Rollgänge entfallen, wobei sich die Investitionskosten reduzieren.The basic idea of the invention is that the compact construction of the rolling mill or of the hot strip mill is created jointly by the consistent use of tandem rolling in the rough rolling mill, in the finishing train or in the rough rolling mill and finishing train. The roughing train alone and / or the finishing train alone or the roughing and finishing train together are tandem mills, ie plant sections in which the mills stand in tandem (tandem arrangement). Due to the resulting compact construction significant parts of the otherwise necessary roller tables can be omitted, thereby reducing the investment costs.

Nach der Erfindung wird vorgeschlagen, dass die Vorwalzstraße als Tandemstraße ausgebildet ist, wobei sie zwei hintereinander angeordnete Vorwalzgerüste umfassen kann. Diese Vorwalzstraße arbeitet vorzugsweise reversierend.According to the invention, it is proposed that the rough rolling mill is designed as a tandem mill, wherein it may comprise two rolling mills arranged one behind the other. This roughing mill is preferably reversing.

Ebenfalls kann die Vorwalzstraße eingerüstig sein. Sie arbeitet dann mit der Fertigstraße im Tandembetrieb. Der Abstand zwischen der Vorwalz- und der Fertigwalzstraße ist so gewählt, dass alle Gerüste gleichzeitig walzen können.Likewise, the roughing mill can be one-armed. She then works with the finishing train in tandem operation. The distance between the pre-rolling and finish-rolling lines is selected so that all stands can roll at the same time.

Zudem wird vorgeschlagen, dass die Fertigwalzstraße zwei Haspeleinrichtungen aufweist und die Fertigwalzstraße im Tandembetrieb betrieben wird.In addition, it is proposed that the finishing train has two reels and the finishing train is operated in tandem.

Das vorgeschlagene Layout ist nicht nur für Neubauten, sondern auch für Modernisierungen bestehender Anlagen geeignet. Insbesondere wird durch das Tandemwalzen in der Vor- und/oder Fertigstraße erreicht, dass kleinere Anlagen, auf denen bisher nur geringere Tonnagen und kleinere Coils produziert wurden, deren Weiterverarbeitung teilweise unwirtschaftlich ist, so umgerüstet werden können, dass bei gleich bleibender Länge der Rollgänge die Bundgewichte (Bandlängen) vergrößert werden können, was die Produktivität erhöht.The proposed layout is not only suitable for new buildings, but also for modernization of existing plants. In particular, it is achieved by tandem rolling in the roughing and / or finishing mill that smaller plants on which previously only smaller tonnages and smaller coils were produced, their further processing is partially uneconomical, can be converted so that the length of the roller tables remains the same Bund weights (tape lengths) can be increased, which increases productivity.

Bei einem bevorzugten Layout sind in der Vorwalzstraße zwei Vorwalzgerüste und in der Fertigwalzstraße zwei Fertigwalzgerüste vorgesehen, die jeweils im Tandembetrieb arbeiten. Insgesamt kann bei diesem Layout mit vier Gerüsten gegenüber dem klassischen Layout mit fünf Gerüsten ein Walzgerüst eingespart werden. Zudem können die beiden Vorwalzgerüste nach dem neuen Layout als kostensparende Duo-Gerüste ausgeführt werden, während die Fertigwalzgerüste Vierwalzen (Quarto-)-gerüste sind.In a preferred layout, two roughing stands are provided in the rough rolling mill and two finishing rolling stands in the finishing mill, each operating in tandem operation. Overall, a roll stand can be saved in this layout with four stands compared to the classic layout with five stands. In addition, the two roughing mills can be designed as cost-saving duo-scaffolds according to the new layout, while the finishing mills are four-high (quarto) scaffolding.

For comparison, the layout of a conventional hot strip mill for aluminum.

Fig. 1 zeigt das neue kompakte Warmwalzwerk-Layout 1 für Aluminium. Die Gegenüberstellung zum Layout 100 nach dem Stand der Technik gemäß Fig. 3 verdeutlicht die Kompaktheit der Anlage nach der Erfindung. Die Anlage besteht ebenfalls aus einem Ofenbereich 2 und der Walzstraße 3 mit einer Vorwalz- und einer Fertigwalzstraße (4, 5). Fig. 1 shows the new compact hot rolling mill layout 1 for aluminum. The comparison with the layout 100 according to the prior art according to Fig. 3 illustrates the compactness of the system according to the invention. The plant also consists of a furnace area 2 and the rolling mill 3 with a roughing and a finishing train (4, 5).

In Transportrichtung hinter dem Ofenbereich 2 sind eine schwere Schopfschere 6 und ein Stauchgerüst 7 angeordnet. Die Vorwalzstraße 4 setzt sich bei der gezeigten Ausführungsform aus zwei hintereinander angeordneten Vorwalzgerüsten 8, 9 zusammen, die im Tandembetrieb reversierend arbeiten. Es folgt eine fliegende Schere 10 zur Vorbereitung des Fertigwalzens. Das Fertigwalzen wird in der Fertigwalzstraße 5 durchgeführt, die aus zwei nah aneinander angeordneten Quarto-Gerüsten 11, 12 besteht, wobei das Band 13 reversierend gewalzt werden kann. Hierzu ist neben einer zweiten Haspeleinrichtung 14 hinter der Fertigwalzstraße 5 noch eine erste Haspeleinrichtung 15 vor der Fertigwalzstraße 5 angeordnet. Mit 16 ist eine Besäumschere bezeichnet.In the transport direction behind the furnace area 2 a heavy cropping shear 6 and a compression frame 7 are arranged. In the embodiment shown, the roughing train 4 is composed of two rough rolling stands 8, 9 arranged one behind the other, which work reversibly in tandem operation. This is followed by flying shears 10 to prepare for finish rolling. The finish rolling is carried out in the finishing train 5, which consists of two closely arranged quarto stands 11, 12, wherein the belt 13 can be reversibly rolled. For this purpose, in addition to a second reeling device 14 behind the finishing train 5, a first reeling device 15 is arranged in front of the finishing train 5. 16 denotes a trimming scissors.

Gegenüber der bekannten Anlage ist die Baulänge der erfindungsgemäßen Anlage nach Fig. 1 deutlich verkürzt, was insbesondere den Abstand zwischen dem Ende der Vorwalzstraße 4 und dem ersten Gerüst 11 der Fertigwalzstraße 5 betrifft. Die vorgeschlagene Anlage ist sehr kompakt, wobei gleichzeitig die Produktion hoher Bundgewichte möglich ist. Im Vergleich zur herkömmlichen Anlage (Fig. 3) ist nur noch eine - fliegende - Schere 10 zwischen der Vorwalz- und der Fertigwalzstraße 4, 5 angeordnet.Compared with the known system, the length of the system according to the invention is after Fig. 1 significantly shortened, which concerns in particular the distance between the end of the rough rolling 4 and the first stand 11 of the finishing train 5. The proposed system is very compact, while at the same time the production of high bundle weights is possible. Compared to the conventional system ( Fig. 3 ) is only one - flying - scissors 10 between the roughing and finish rolling 4, 5 arranged.

Das Verfahren selbst wird mit Hilfe der Fig. 2 verdeutlicht. Zum Warmwalzvorgang wird ein warmer Aluminium-Barren 17 auf einen Rollgang 18 aufgelegt und in die Vorwalz-Trandemstraße 4 transportiert und dort reversierend in den beiden Vorwalzgerüsten 8, 9 im Tandembetrieb ausgewalzt, beispielsweise dreimal hin- und zurück, wie durch die Pfeile a gezeigt und mit Walzschritt l bezeichnet. Das Bandende wird mittels der schweren Schere 6 zwischen geschopft. Nach ausrechenden Reversiervorgängen kann die jetzt vorliegende Platine 19 direkt in das Fertigwalzgerüst 5 transportiert werden unter gleichzeitiger Beteiligung aller Gerüste. Es findet demnach ein Tandembetrieb in allen Gerüsten der Vorwalz- und Fertigwalzgerüst statt. Die Platine 19 wird durch ein Tandemwalzen in den Gerüsten 11, 12 der Fertigwalzstraße 5 zum Band 13 fertig gewalzt (Walzschritt II).The process itself is using the Fig. 2 clarified. For hot rolling a hot aluminum ingot 17 is placed on a roller table 18 and transported in the roughing Trandemstraße 4 and there reversing in the two roughing stands 8, 9 rolled out in tandem, for example, three times back and forth, as shown by the arrows a and denoted by rolling step l. The end of the tape is stuffed by means of heavy scissors 6 between. After ausrechenden Reversiervorgängen the now present board 19 can be transported directly into the finishing mill 5 with the simultaneous participation of all scaffolding. Accordingly, a tandem operation takes place in all the stands of the roughing and finish rolling stand. The board 19 is rolled by tandem rolling in the stands 11, 12 of the finishing train 5 to the belt 13 (rolling step II).

Nach einer anderen Verfahrensvariante (IIb) wird das Vorwalzprodukt durch Tandemwalzen in Fertigwalzgerüsten 11, 12 zwischen den beiden Haspeleinrichtungen 14, 15 reversierend ausgewalzt. Das Band 13 wird nach dem ersten Walzvorgang unter gleichzeitiger Beteiligung der beiden Fertigwalzgerüste 11, 12 mit der zweiten Haspeleinrichtung 14 aufgewickelt. Das Bandende wird mit einer fliegenden Schere 10 geschopft. Anschließend wird die Umlaufrichtung der jeweiligen Ober- und Unterwalzen der Gerüste 11, 12 geändert (Pfeil b) und das Band 13 erneut in die Fertigwalzgerüste 11, 12 eingezogen. Das Band 13 wird von der ersten Haspeleinrichtung 15 aufgehaspelt und gleichzeitig von der zweiten Haspeleinrichtung 14 abgewickelt und anschließend wieder umgekehrt (Pfeil c). Der Reversiervorgang kann entsprechend der gewünschten Enddicke des Bandes 13 wiederholt werden.According to another variant of the method (IIb), the rough rolling product is rolled reversibly by tandem rolling in finish rolling stands 11, 12 between the two reeling devices 14, 15. The strip 13 is wound after the first rolling operation with simultaneous participation of the two finishing stands 11, 12 with the second coiler 14. The end of the tape is stuffed with flying scissors 10. Subsequently, the direction of rotation of the respective upper and lower rollers of the stands 11, 12 is changed (arrow b) and the belt 13 again retracted into the finishing mills 11, 12. The tape 13 is unwound from the first coiler 15 and simultaneously unwound from the second coiler 14 and then reversed again (arrow c). The reversing process can be repeated according to the desired final thickness of the strip 13.

Durch die Nutzung der Tandemwalzungen in einer Warmbandstraße für Aluminium kann insbesondere erreicht werden, dass bisher unwirtschaftlich arbeitende kompakte Anlagen ihre Produktivität und Wirtschaftlichkeit wesentlich steigern können.By using the tandem rolling in a hot strip mill for aluminum can be achieved in particular that previously uneconomical working compact plants can increase their productivity and efficiency significantly.
