Description

Die Erfindung betrifft eine Anordnung einer Speichervorrichtung in einer Bandstraße zum Warmwalzen von Metallwerkstücken, insbesondere Brammen, bestehend aus einer Vorstraße und einer nachgeschalteten Fertigstraße mit den ihnen zugehörigen Rollgängen, wobei zwischen Vor- und Fertigstraße eine Aufwickelstation und eine Abwickelstation für das in der Vorstraße gewalzte Band in einer Warmhaltestation angeordnet sind und die Walzlinien der Vor-und Fertigstraße zueinander versetzt sind.The invention relates to an arrangement of a storage device in a strip mill for hot rolling metal workpieces, in particular slabs, consisting of a roughing mill and a downstream finishing mill with the associated roller tables, with a winding station and an unwinding station for the strip rolled in the roughing mill between the roughing and finishing mill are arranged in a holding station and the rolling lines of the roughing and finishing train are offset from one another.

Aus der DE-C-906 086 ist eine derartige Anordnung bekannt. Dabei sind allerdings Reversiergerüste als Fertigwalzgerüste eingesetzt, was bei modernen Walzstraßen nicht mehr angewendet wird.Such an arrangement is known from DE-C-906 086. However, reversing stands are used as finishing stands, which is no longer used in modern rolling mills.

Um die heute angestrebten hohen Stra- ßenleistungen zu erzielen, wird die Fertigstraße als Einheit von 5 bis 7 Einzelgerüsten, die jeweils nur einen Stich erzeugen, ausgeführt.In order to achieve the high road performance we are striving for today, the finishing train will be designed as a unit of 5 to 7 individual stands, each of which will only produce one pass.

Das häufige Haspeln des Streifens bei der bekannten Lösung aus der DE-C-906 086, das beim Walzen auf Reversiergerüsten notwendig ist, kann zur Beschädigung der Bandoberfläche führen, was für die Weiterverarbeitung sehr nachteilig ist. Der Arbeitsablauf bei dieser bekannten Anordnung ist derart, daß vor dem letzten Walzstich im Gerüst g der Haspel h aus der Walzlinie x nach rechts fährt und der Haspel k sich an seine Stelle setzt. Danach beginnt Gerüst g den letzten Stich. Wenn der Haspel k gefüllt ist, fährt er in die Linie y, Haspel h begibt sich sodann in Arbeitsposition in Linie x, so daß Gerüst g dann mit dem Walzen beginnen kann. Diese Arbeitsweise ist insofern nachteilig, da Linie y erst wieder beschickt werden kann, wenn der Haspel k in Linie x gefüllt ist.The frequent reeling of the strip in the known solution from DE-C-906 086, which is necessary when rolling on reversing stands, can damage the strip surface, which is very disadvantageous for further processing. The workflow in this known arrangement is such that before the last roll pass in the stand g, the reel h moves out of the rolling line x to the right and the reel k takes its place. Then scaffold g begins the last stitch. When the reel k is filled, it moves in line y, reel h then moves to line x in the working position, so that stand g can then begin rolling. This method of operation is disadvantageous in that line y cannot be loaded again until the reel k in line x is filled.

In Abhängigkeit von den Walzlängen und Walzzeiten kann es dabei zu Überschneidungen kommen, so daß die Straße zeitlich nicht optimal genutzt werden kann (Wartezeiten).Depending on the rolling lengths and times, there may be overlaps so that the road cannot be used optimally in terms of time (waiting times).

Von daher ist es Aufgabe der Erfindung, eine Anordnung einer Speichervorrichtung in einer Bandstraße der eingangs genannten Art zu schaffen, die auf einfache Weise eine höhere Leistung ermöglicht und Wartezeiten in den einzelnen Walzlinien vermeidet.It is therefore an object of the invention to provide an arrangement of a storage device in a strip mill of the type mentioned at the outset which enables higher performance in a simple manner and avoids waiting times in the individual rolling lines.

Nach der Erfindung wird die Aufgabe in der Weise gelöst, daß die Abwickelstation fest in der Walzlinie der Fertigstraße installiert und zwischen Auf- und Abwickelstation eine Quertransporteinrichtung angeordnet ist, wobei bei Verwendung eines Umkehrwalzgerüstes in der Vorstraße der Auslaufrollgang hinter dem Umkehrwalzgerüst unter der Warmhaltestation mit der Aufwickelstation und der Quertransporteinrichtung hindurch verlängert ist.According to the invention, the object is achieved in such a way that the unwinding station is installed permanently in the rolling line of the finishing train and a transverse transport device is arranged between the winding and unwinding station, the outlet roller table behind the reversing roll stand under the holding station with the using a reversing roll stand in the roughing train Winding station and the transverse transport device is extended through.

Dadurch kann der Transport der aufgewickelten Ringe mit einem separaten, zwischen Auf- und Abwickelstation verkehrenden Transportwagen vorgenommen werden, d. h. Trennung der Funktionen Aufwickeln, Transportieren und Abwickeln. Dieser Transportwagen dient gleichzeitig als Puffer, der zusätzlich noch zeitliche Störungen in den Walzstraßen ausgleichen kann.As a result, the wound-up rings can be transported using a separate transport trolley which runs between the winding and unwinding station, i. H. Separation of the winding, transporting and unwinding functions. This trolley also serves as a buffer, which can also compensate for time disturbances in the rolling mills.

Dadurch können beide Walzlinien unabhängig voneinander betrieben werden, was eine wesentlich höhere Straßenleistung erbringt.This means that both rolling lines can be operated independently of one another, which results in a significantly higher road performance.

In bezug auf die dargelegte Straßenanordnung (Fertigstraße als Konti-Anordnung in Einzelgerüsten) ermöglicht die Haspelausführung und -Anordnung ein Unterfahren des ersten Haspels (bzw. der Quertransporteinrichtung), hinter dem entsprechende Rollgänge angebracht sind. Dadurch lassen sich auf kürzerem Raum höhere Ringgewichte walzen, was die Leistung der Straße weiter erhöht und den Aufwand an Hallenfläche verringert.With regard to the road arrangement described (finishing line as a continuous arrangement in individual scaffolding), the reel design and arrangement enables the first reel (or the transverse transport device) to be passed underneath, behind which corresponding roller tables are attached. This means that higher ring weights can be rolled in a shorter space, which further increases the performance of the street and reduces the amount of hall space required.

Eine Ausführungsform kann derart aufgebaut sein, daß Vor- und Fertigstraße Z-förmig zueinander versetzt sind.An embodiment can be constructed in such a way that the roughing and finishing lines are offset from one another in a Z-shape.

Eine sehr kompakte Ausführungsform kennzeichnet sich in vorteilhafter Weise dadurch, daß Vor- und Fertigstraße U-förmig zueinander angeordnet sind.A very compact embodiment is characterized in an advantageous manner in that the roughing and finishing lines are arranged in a U-shape with respect to one another.

In der Zeichnung ist die Anordnung einer Speichervorrichtung in einer Bandstraße nach der Erfindung anhand von schematischen Ausführungsbeispielen näher erläutert.In the drawing, the arrangement of a storage device in a belt line according to the invention is explained in more detail using schematic exemplary embodiments.

Die Fig. 1 bis 4 zeigen eine Walzstraße für Metallbrammen, die aus einer Vorstraße 1-und einer dazu versetzten, nachgeschalteten Fertigstraße 2 mit ihren zugehörigen Rollgängen 3, 4 und 5 besteht. Zwischen der Vorstraße 1, die aus einem Umkehrwalzgerüst 6 besteht, und der Fertigstraße 2 ist eine Warmhaltestation 7 mit einer Aufwickelstation 8 und einer Abwickelstation 9 für das in der Vorstraße 1 gewalzte Band angeordnet.1 to 4 show a rolling mill for metal slabs, which consists of a roughing mill 1 and a downstream finishing mill 2 with its associated roller tables 3, 4 and 5 which are offset from it. A warming station 7 with a winding station 8 and an unwinding station 9 for the strip rolled in the roughing train 1 is arranged between the roughing train 1, which consists of a reversing roll stand 6, and the finishing train 2.

Die Abwickelstation 9 ist dabei aus der Walzlinie der Vorstraße 1 quer in die Walzlinie der Fertigstraße 2 verfahrbar, wie in den Fig. 1 bis 3 dargestellt ist. Die Fig. 4 zeigt dagegen, daß die Abwickelstation 9 fest in der Walzlinie der Fertigstraße 2 installiert ist und zwischen der Aufwickelstation 8 in der Walzlinie der Vorstraße 1 und der Abwickelstation 9 eine Quertransporteinrichtung 10 angeordnet ist, die gleichzeitig als Puffer zwischen Vorstraße 1 und Fertigstraße 2 dienen kann, wobei es möglich ist, daß sich gleichzeitig Coils in der Aufwickelstation 8, auf der Quertransporteinrichtung 10 als Wartestation und in der Abwickelstation 9 befinden.The unwinding station 9 can be moved transversely from the rolling line of the roughing train 1 into the rolling line of the finishing train 2, as shown in FIGS. 1 to 3. Fig. 4 shows, on the other hand, that the unwinding station 9 is permanently installed in the rolling line of the finishing train 2 and between the winding station 8 in the rolling line of the roughing train 1 and the unwinding station 9, a transverse transport device 10 is arranged, which is also a buffer between the roughing train 1 and the finishing train 2 can serve, it being possible for coils to be located in the winding station 8, on the transverse transport device 10 as a waiting station and in the unwinding station 9 at the same time.

Die Fig. 1, 3 und 4 zeigen, daß die Vorstraße 1 und Fertigstraße 2 Z-förmig zueinander versetzt sein können, wogegen in der Fig. 2 eine U-förmige Anordnung dargestellt wird, was eine sehr kompakte Walzstraße bedeutet. Die Anlandung der Brammen und der Versand des Fertigmaterials können an einer Stelle konzentriert werden, Preßwassererzeugnungsstation und Versorgungsanlagen können zentral mit geringem Abstand von den Walz- und Nebenaggregaten angeordnet werden.1, 3 and 4 show that the roughing mill 1 and finishing mill 2 are offset in a Z-shape can be, whereas a U-shaped arrangement is shown in FIG. 2, which means a very compact rolling mill. The landing of the slabs and the dispatch of the finished material can be concentrated in one place, press water generation station and supply systems can be arranged centrally with a short distance from the rolling and auxiliary units.

Die mögliche walzbare Streifenlänge kann erhöht werden, wenn der Auslaufrollgang 4 hinter der Vorstraße 1 unter der Warmhaltestation 7 mit der Aufwickelstation 8 hindurch verlängert 11 ist, wie die Fig. 3 zeigt.The possible rollable strip length can be increased if the outlet roller table 4 behind the roughing mill 1 is extended 11 under the warming station 7 with the winding station 8, as shown in FIG. 3.

Der mittels des Umkehrwalzgerüstes 6 in der Vorstraße 1 gewalzte Streifen kann in allen Stichen vor dem Fertigstich die Warmhaltestation 7 mit der Aufwickelstation 8 unterfahren. Erst das aus dem Fertigstich in der Vorstraße 1 kommende Band wird in der Aufwickelstation 8 aufgehaspelt.The strip rolled in the roughing train 1 by means of the reversing roll stand 6 can pass under the warming station 7 with the winding station 8 in all passes before the finish stitch. Only the tape coming from the finish stitch in Vorstraße 1 is wound up in the winding station 8.

Der Walzvorgang in der Walzstraße nach der erfindungsgemäßen Anordnung geht so vonstatten, daß das aus der Vorstraße 1 auslaufende Band in der Aufwickelstation 8 aufgehaspelt, an die Abwickelstation 9 direkt (Fig. 1-3) oder über die Quertransporteinrichtung 10 (Fig. 4) übergeben und von der Abwickelstation 9 abgehaspelt und in die Fertigstraße 2 geführt wird.The rolling process in the rolling mill according to the arrangement according to the invention takes place in such a way that the strip running out of the roughing mill 1 is coiled up in the winding station 8, passed directly to the unwinding station 9 (FIGS. 1-3) or via the transverse transport device 10 (FIG. 4) and uncoiled from the unwinding station 9 and guided into the finishing train 2.

Wird das aufgehaspelte Band direkt von der Aufwickelstation an die Abwickelstation 9 übergeben, wird diese quer aus der Walzlinie der Vorstraße 1 in die Walzlinie der Fertigstraße 2 verfahren (Fig. 1 bis 3). Nachdem das Band die Abwickelstation 9 verlassen hat, fährt sie in die Walzlinie der Vorstraße 1 zurück und übernimmt erneut das inzwischen in der Aufwickelstation 8 aufgehaspelte Band.If the reeled-up strip is transferred directly from the winding station to the unwinding station 9, this is moved transversely from the rolling line of the roughing train 1 into the rolling line of the finishing train 2 (FIGS. 1 to 3). After the strip has left the unwinding station 9, it moves back into the rolling line of the Vorstraße 1 and again takes over the band that has meanwhile been rewound in the winding station 8.

Ist die Abwickelstation 9 jedoch fest in der Walzlinie der Fertigstraße 2 installiert, wird das in der Aufwickelstation 8 aufgehaspelte Band an die Quertransporteinrichtung 10 übergeben, die dann das aufgehaspelte Band quer in die Walzlinie der Fertigstraße 2 transportiert und an die dort fest installierte Abwickelstation 9 übergibt.However, if the unwinding station 9 is permanently installed in the rolling line of the finishing train 2, the strip coiled in the winding station 8 is transferred to the transverse transport device 10, which then transports the coiled strip transversely into the rolling line of the finishing train 2 and transfers it to the unwinding station 9 permanently installed there .

Die Aufwickelstation 8 ist nach der Abgabe des aufgehaspelten Bandes an die Abwickelstation 9 oder die Quertransporteinrichtung 10 sofort wieder aufnahmebereit für das nachfolgende Band.The take-up station 8 is immediately ready to take up the following tape once the reeled-up tape has been delivered to the take-off station 9 or the transverse transport device 10.

Aufwickelstation 8, Abwickelstation 9 und Quertransporteinrichtung 10 sind in der Warmhaltestation 7 angeordnet, damit das aufzuwickelnde querzutransportierende und abzuwickelnde Band auf Walztemperatur gehalten wird.Rewinding station 8, unwinding station 9 and transverse transport device 10 are arranged in the warming station 7 so that the strip to be wound up to be transversely transported and unwound is kept at the rolling temperature.
