Description

Verfahren und Anlage zum Walzen von WalzgutProcess and plant for rolling rolled material
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 rolling mill and at least one reel arranged in front of it and a reel for winding up or unwinding the rolling stock, a welding device and a strip storage device.
Zum Walzen von Walzgut, insbesondere von Metallband, sind unterschiedliche Verfahren bzw. Anlagen bekannt. So gibt es Einzelgerüste, Reversier- oder Umkehrgerüste, Tandemstrassen und Contistrassen.Various methods and systems are known for rolling rolled material, in particular metal strip. So there are single scaffolding, reversing or reversing scaffolding, tandem streets 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 Walzstras- se endlos zur Verfügung.In order to achieve the acceptance of rolled material to the finished thickness, the rolled material has to go through this several times in the case of individual stands. If several rolling stands are built one behind the other to form a tandem mill, the rolling stock need only pass through the tandem mill once. The reduction in the thickness of the rolling stock from the raw dimension to the finished dimension determines the number of mill stands installed. Contistrassen are a further development of tandem streets. Here, the strip end of the rolled material of one coil is connected to the strip start of the next coil, for example by welding. The advantage of such a system or method is that there is no need to thread the rolling stock from each coil, the rolling stock is endlessly available to the rolling train.
Eine derartige Anlage lässt sich nur bei grossem Durchsatz wirtschaftlich betreiben.Such a system can only be operated economically with high throughput.
Für kleinere Mengen an Walzgut werden daher Anlagen eingesetzt, bei denen nur eine geringe Anzahl von Walzgerüsten berücksichtigt werden. Hier hat sichFor smaller quantities of rolling stock, systems are therefore used in which only a small number of roll stands are taken into account. Here has
BESTATIGUNGSKOPIE ein Verfahren und eine Vorrichtung etabliert, bei der das Walzgut mehrmals ein oder zwei Walzgerüste durchläuft, ohne dass das Walzgut den Walzspalt verläset. 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.BESTATIGUNGSKOPIE established a method and a device in which the rolling stock passes through one or two roll stands several times without the rolling stock leaving the roll gap. For this purpose, the rolled material wound into a coil is passed from a decoiler through one or more roll stands and wound onto another coiler. In order to roll several passes, the rolling stock is shaped in the back and forth between the adjustable rolls.
Aus der DE 43 10 063 A1 ist eine Anlage zum Kaltwalzen von bandförmigen Walzgut mit einem, zwischen zwei Reversierhaspeln angeordneten Reversier- gerüst und einem Haspel, von dem das Einsatzband abwickelbar ist, bekannt.DE 43 10 063 A1 discloses a system for cold rolling strip-shaped rolling stock with a reversing stand arranged between two reversing reels and a reel from which the insert strip can be unwound.
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 US 2,105,736 a reversing system is shown in which an endless length of rolling stock is used. For this purpose, the system has a horizontal strip store before and after the roll stand. The rolling stock is fed from a reel into the front strip storage. The end of the strip of a first coil is welded to the beginning of the next coil and is reversely deformed in the roll stand.
Eine derartige Anlage lässt sich ebenfalls nur bei grossen Durchsatz wirtschaftlich betreiben.Such a system can also only be operated economically with 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 based on the object of providing a method and a system, taking into account at least one reversing rolling mill, in order to offer economical processing of rolled material.
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 according to the invention by a method in which the metal strip is wound onto the decoiler during the reversing stitches and a further strip start of another metal strip is welded onto the strip end of the metal strip before the last pass.
Eine erfindungsgemäße Anlage sieht vor, dass der Abwickelhaspel für die Re- versierstiche als Bandspeicher benutzt wird. Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.A system according to the invention provides that the decoiler for the reversing stitches is used as a tape store. 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 fal- len 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 two coil lengths together, shorter coil follow-up times are achieved, since there is no need to thread each coil. In addition, there are fewer dimensional lengths, since the strip ends are rolled out and the start of each additional coil is rolled on at least once. The beginning and end of the strip are always rolled under optimal tensile conditions in the method and the system according to the invention.
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 decoilers can simultaneously function as the decoiler of an upstream pickling line. In this way, an expensive transport of the individual coils is avoided, with damage to the coils no longer occurring due to the transport.
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 system, for example between the welding machine and the reversing rolling mill. An adapted, larger tape storage device must be provided for this.
Ein Ausführungsbeispiel der Erfindung wird anhand einer sehr schematischen Zeichnung näher beschrieben. Es zeigt:An embodiment of the invention is described in more detail using a very schematic drawing. It shows:
Fig. 1 eine Darstellung einer erfindungsgemäßen zweigerüstigen Rever- sierstrasse mit Schweißvorrichtung, Bandspeicher sowie Abwi- ekel- und Aufwickelhaspeln.1 shows an illustration of a two-stand reversing line according to the invention with a welding device, a strip storage device and a reel and take-up reel.
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 Wal- zen des Coils. Auf einem weiteren Abwickelhaspel 6 wird ein weiteres Coil 7 vorgehalten.A reverse or reversing street is shown in the single figure. A metal strip 3 is unwound from a coil 2 on a decoiler 1 and passed through a welding device 4, a strip store 5 and a roll stand 8 and fed to a decoiler 9 for the first roll. zen of the coil. Another coil 7 is kept on a further decoiler 6.
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 last third of the coil 2, the strip store 5 is opened in order to bridge the time span for the welding of the strip end of coil 2 with the strip start of coil 7 for further rolling. As a result, the metal strip 3 can be rolled out from coil 2 to the weld seam and a few meters beyond. When reversing to roll the metal strip 3 to the desired thickness by means of adjustable rolls, the assembled metal strip 3 is alternately wound onto the reel 6 and the reel 9. The following coil is already positioned on the decoiler 1 in order to be welded to the end of the metal strip 3 by 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.When the target thickness is reached, the metal strip 3 is wound on the take-up reel 9 to form a coil 10 of a predetermined length. For this purpose, the metal strip 3 is cut. 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, a further metal strip 3 is welded in the welding machine 4 by a coil 2 or 7 of the decoiler 1 or 6 to the non-deformed metal strip 3 remaining in the strip store 5. Subsequently, without further interruption, the next length of the metal strip 3 is deformed further.
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 zeitrauben- den Richtungswechsel einer Reversieranlage zu halbieren. Voraussetzung hierfür ist, dass die Metallbänder der Coils gleiche Abmessungen haben. With the same device, so-called jumbo coils (each with two or more normal coils connected to one another) can be put together and rolled out and fed and removed as normal coils in order to halve the time-consuming change of direction of a reversing system. The prerequisite for this is that the metal strips of the coils have the same dimensions.
