Abstract

The invention relates to a method of rolling a strip-shaped in-process stock, in particular a metal strip, with which, a metal strip ( 3 ) is unwound from a coil ( 2, 7 ) held on an unwinding reel ( 1, 6 ), is fed into a reversing rolling mill ( 8 ), is rolled, and is wound-up onto a winding-up reel ( 9 ) to form a coil ( 10 ), wherein the metal strip ( 3 ) is reversibly conveyed from the unwinding reel ( 1, 6 ) to the winding-up reel ( 9 ) until a set thickness is reached and, with each passing of the reversing rolling mill ( 8 ), is subjected to a reduction of thickness, and wherein an end of the metal strip ( 3 ) of a first coil is welded to a beginning of the metal strip ( 3 ) of the second coil, and the metal strip ( 3 ) of the first coil is temporarily stored in a strip store during a welding process, and finally, the in-process stock consisting of two lengths is reversibly rolled to a final dimension, and an additional length is welded to the end of the in-process stock before the last pass. The invention also relates to an installation for effecting the method and in which the unwinding reel ( 1, 6 ) is used as a strip store for the reverse pass.

Description

Die Erfindung betrifft ein Verfahren und eine Anlage zum Walzen von bandförmigen Walzgut, insbesondere Metallband, bestehend aus mindestens einem Reversierwalzwerk und mindestens einer davor und einer danach angeordneten Haspel zum Auf- bzw. Abwickeln des Walzgutes, einer Schweißvorrichtung und einem Bandspeicher.The invention relates to a method and a system for rolling strip-shaped rolling stock, in particular metal strip, consisting of at least one reversing and at least one before and a subsequent arranged reel for winding or unwinding of the rolling stock, a welding device and a tape storage.

Zum Walzen von Walzgut, insbesondere von Metallband, sind unterschiedliche Verfahren bzw. Anlagen bekannt. So gibt es Einzelgerüste, Reversier- oder Umkehrgerüste, Tandemstrassen und Contistrassen.For rolling of rolling stock, in particular of metal strip, different methods or equipment are known. So there are single scaffolding, reversing or reverse scaffolding, tandem roads and Contistrassen.

Um die Abnahme von Walzgut auf Fertigdicke zu realisieren muss das Walzgut bei Einzelgerüsten dieses mehrmals durchlaufen. Sind mehrere Walzgerüste hintereinander zu einer Tandemstrasse aufgebaut, so braucht das Walzgut die Tandemstrasse nur einmal zu durchlaufen. Die Reduzierung der Dicke des Walzgutes vom Rohmass auf Fertigmass bestimmt die Anzahl der aufgestellten Walzgerüste. Contistrassen sind eine Weiterentwicklung der Tandemstrassen. Hierbei wird das Bandende des Walzgutes eines Coils mit dem Bandanfang des nächsten Coils beispielsweise durch Schweissen verbunden. Der Vorteil einer solchen Anlage bzw. eines derartigen Verfahrens besteht darin, dass das Einfädeln des Walzgutes von jedem Coil entfällt, das Walzgut steht der Walzstrasse endlos zur Verfügung.In order to realize the decrease of rolling stock to finished thickness, the rolling stock has to pass through this several times for single stands. If several rolling stands are built one behind the other to form a tandem track, then the rolling stock only has to pass through the tandem track once. The reduction of the thickness of the rolling stock from raw stock to finished size determines the number of erected rolling stands. Contistrials are a further development of tandem roads. In this case, the band end of the rolling stock of a coil is connected to the beginning of the band of the next coil, for example by welding. The advantage of such a system or such a method is that the threading of the rolling stock of each coil is eliminated, the rolling stock is the Walzstrasse endlessly available.

Eine derartige Anlage lässt sich nur bei grossem Durchsatz wirtschaftlich betreiben.Such a system can be operated economically only at high throughput.

Für kleinere Mengen an Walzgut werden daher Anlagen eingesetzt, bei denen nur eine geringe Anzahl von Walzgerüsten berücksichtigt werden. Hier hat sich ein Verfahren und eine Vorrichtung etabliert, bei der das Walzgut mehrmals ein oder zwei Walzgerüste durchläuft, ohne dass das Walzgut den Walzspalt verlässt. Hierzu wird das zu einem Coil aufgewickelte Walzgut von einem Abwickelhaspel durch ein oder mehrere Walzgerüste geleitet und auf einen weiteren Haspel aufgewickelt. Um mehrere Stiche zu walzen, wird das Walzgut im Hin- und Hergang zwischen den nachstellbaren Walzen geformt.For smaller quantities of rolling stock, therefore, plants are used in which only a small number of rolling stands are taken into account. Here has become a method and an apparatus is established in which the rolling stock passes through one or two rolling mills several times without the rolling stock leaving the nip. For this purpose, the wound into a coil rolling stock is passed from a decoiler by one or more rolling stands and wound on another reel. In order to roll multiple passes, the rolling stock is formed in the outward and forward between the adjustable rollers.

Aus der DE 43 10 063 A1 ist eine Anlage zum Kaltwalzen von bandförmigen Walzgut mit einem, zwischen zwei Reversierhaspeln angeordneten Reversiergerüst und einem Haspel, von dem das Einsatzband abwickelbar ist, bekannt.From the DE 43 10 063 A1 is a system for cold rolling strip-shaped rolling with a, arranged between two reversing reels reversing stand and a reel, from which the insert belt is unwound known.

In der US 2,105,736 ist eine Reversieranlage dargestellt, bei der eine endlose Länge von Walzgut eingesetzt wird. Hierzu besitzt die Anlage vor und nach dem Walzgerüst je einen horizontalen Bandspeicher. Das Walzgut wird von einem Haspel in den vorderen Bandspeicher geleitet. Das Bandende eines ersten Coils wird mit dem Anfang des nächsten Coils verschweisst und im Walzgerüst im Umkehrverfahren verformt.In the US 2,105,736 a reversing plant is shown, in which an endless length of rolling stock is used. For this purpose, the system has before and after the rolling mill each a horizontal tape storage. The rolling stock is guided by a reel in the front strip storage. The strip end of a first coil is welded to the beginning of the next coil and deformed in the rolling mill in the inverse process.

Eine derartige Anlage lässt sich ebenfalls nur bei grossen Durchsatz wirtschaftlich betreiben.Such a system can also operate economically only at high throughput.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Anlage zu schaffen, unter Berücksichtigung mindestens eines Reversierwalzwerks, um eine wirtschaftliche Bearbeitung von Walzgut anzubieten.The invention is therefore an object of the invention to provide a method and a system, taking into account at least one reversing mill to offer an economical processing of rolling stock.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst indem das Metallband bei den Reversierstichen auf den Abwickelhaspel aufgewickelt wird und vor dem letzten Durchlauf an das Bandende des Metallbandes ein weiterer Bandanfang eines weiteren Metallbandes angeschweisst wird.This object is achieved by a method by the metal strip is wound in the reversing stitches on the unwinding and before the last pass to the band end of the metal strip another beginning of the tape another metal strip is welded.

Eine erfindungsgemäße Anlage sieht vor, dass der Abwickelhaspel für die Reversierstiche als Bandspeicher benutzt wird.An inventive system provides that the unwinding reel is used for the reversing stitches as a tape storage.

Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Embodiments of the invention are specified in the subclaims.

Durch das Zusammenschweißen zweier Coillängen werden kürzere Bundfolgezeiten erreicht, da das aufwendige Einfädeln jedes Coils entfällt. Außerdem fallen weniger Abmaßlängen an, da die Bandenden ausgewalzt werden sowie der Bandanfang jedes weiteren Coils mindestens einmal angewalzt wird. Bandanfang und Bandende werden bei dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Anlage immer unter optimalen Zugbedingungen gewalzt.By welding together two coil lengths shorter follow-up times are achieved because the complex threading of each coil is eliminated. In addition, less Maßmaßlänge, since the band ends are rolled out and the beginning of each additional coil is rolled at least once. Beginning of the tape and the end of the tape are always rolled in the process of the invention and the system according to the invention under optimum tensile conditions.

Bei einer vorteilhaften Ausgestaltung einer derartigen Anlage kann eine der beiden Abwickelhaspeln gleichzeitig die Funktion der Aufwickelhaspel einer vorgeschalteten Beizlinie bilden. Hierdurch wird ein aufwendiger Transport der einzelnen Coils vermieden, wobei Beschädigungen an den Coils durch den Transport nicht mehr auftreten.In an advantageous embodiment of such a system, one of the two uncoiler can simultaneously form the function of the take-up reel an upstream pickling line. As a result, a complex transport of the individual coils is avoided, with damage to the coils by transport no longer occur.

Wie die Erfindung weiter vorsieht, kann die Beizlinie auch in die Anlage, beispielsweise zwischen der Schweißmaschine und dem Reversierwalzwerk integriert werden. Hierzu ist ein angepasster, größerer Bandspeicher vorzusehen.As the invention further provides, the pickling line can also be integrated into the plant, for example between the welding machine and the reversing mill. For this purpose, an adapted, larger tape storage is provided.

Ein Ausführungsbeispiel der Erfindung wird anhand einer sehr schematischen Zeichnung näher beschrieben. Es zeigt:

Fig. 1
eine Darstellung einer erfindungsgemäßen zweigerüstigen Reversierstrasse mit Schweißvorrichtung, Bandspeicher sowie Abwickel- und Aufwickelhaspeln.
An embodiment of the invention will be described with reference to a very schematic drawing. It shows:
Fig. 1
an illustration of a zweigerüstigen Reversierstrasse invention with welding device, tape storage and unwinding and Aufwickelhaspeln.

In der einzigen Figur ist eine Umkehr- oder Reversierstrasse dargestellt. Auf einem Abwickelhaspel 1 wird von einem Coil 2 ein Metallband 3 abgewickelt und durch eine Schweißvorrichtung 4, einen Bandspeicher 5 sowie einem Walzgerüst 8 geführt und einem Aufwickelhaspel 9 zugeführt, zum ersten Walzen des Coils. Auf einem weiteren Abwickelhaspel 6 wird ein weiteres Coil 7 vorgehalten.
Im letzten Drittel des Coils 2 wird der Bandspeicher 5 aufgefahren um die Zeitspanne für das Anschweissen des Bandendes von Coil 2 mit dem Bandanfang von Coil 7 zum Weiterwalzen zu überbrücken. Hierdurch kann das Metallband 3 von Coil 2 bis an die Schweißnaht und einige Meter darüber hinaus ausgewalzt werden. Beim Reversieren zum Walzen des Metallbandes 3 auf Solldicke mittels nachstellbaren Walzen wird das zusammengefügt Metallband 3 abwechselnd auf den Haspel 6 und den Haspel 9 aufgewickelt. Auf dem Abwickelhaspel 1 wird schon das nachfolgende Coil positioniert, um an das Bandende des Metallbandes 3 von Coil 7 angeschweisst zu werden.In the single figure, a reversing or Reversierstrasse is shown. On a decoiler 1, a metal strip 3 is unwound from a coil 2 and passed through a welding device 4, a belt store 5 and a roll stand 8 and fed to a take-up reel 9 for the first rolling of the coil. On another unwinding reel 6 another coil 7 is kept.
In the last third of the coil 2 of the tape storage is 5 ascended to bridge the period of time for the welding of the tape end of coil 2 with the beginning of the coil 7 for further rolling. As a result, the metal strip 3 of coil 2 can be rolled to the weld and a few meters beyond. When reversing to roll the metal strip 3 to desired thickness by means of adjustable rollers, the joined metal strip 3 is wound alternately on the reel 6 and the reel 9. On the uncoiler 1, the following coil is already positioned to be welded to the band end of the metal strip 3 of coil 7.

Bei Erreichen der Solldicke wird das Metallband 3 auf dem Aufwickelhaspel 9 zu einem Coil 10 vorbestimmter Länge aufgewickelt. Hierzu wird das Metallband 3 durchtrennt. Nachdem das fertige Coil 10 von dem Aufwickelhaspel 9 abgenommen wurde, wird das verbleibende Metallband 3 mit dem Aufwickelhaspel 9 verbunden. Gleichzeitig wird in der Schweißmaschine 4 ein weiteres Metallband 3 von einem Coil 2 oder 7 der Abwickelhaspel 1 oder 6 mit dem im Bandspeicher 5 verbliebenen, nicht verformten Metallband 3 verschweisst. Anschließend erfolgt, ohne Unterbrechung, die weitere Verformung der nächsten Länge des Metallbandes 3.Upon reaching the target thickness, the metal strip 3 is wound on the take-up reel 9 to form a coil 10 of predetermined length. For this purpose, the metal strip 3 is severed. After the finished coil 10 has been removed from the take-up reel 9, the remaining metal strip 3 is connected to the take-up reel 9. At the same time in the welding machine 4, another metal strip 3 is welded by a coil 2 or 7 of the unwinding reel 1 or 6 with the non-deformed metal strip 3 remaining in the strip accumulator 5. Subsequently, without further interruption, the further deformation of the next length of the metal strip 3 takes place.

Durch die gleiche Einrichtung lassen sich auch sogenannte Jumbo - Coils (je zwei oder mehrere normale Coils zu einem verbunden) zusammenstellen und auswalzen und als normale Coils zuführen und abnehmen, um die zeitraubenden Richtungswechsel einer Reversieranlage zu halbieren. Voraussetzung hierfür ist, dass die Metallbänder der Coils gleiche Abmessungen haben.By the same device can also be so-called Jumbo - coils (two or more normal coils to a connected) put together and roll out and feed as normal coils and remove to halve the time-consuming changes of direction of a reversing system. The prerequisite for this is that the metal strips of the coils have the same dimensions.
