Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines metallischen Bandes im kontinuierlichen Gießwalzverfahren, bei dem zunächst eine Bramme in einer Gießmaschine gegossen und einem in Förderrichtung des Bandes nachgelagerten Fertig-Walzwerk zugeführt und hier gewalzt wird. Des weiteren betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens. Ein gattungsgemässes Verfahren bzw. eine gattungsgemässe Vorrichtung sind aus KR 20130053111 A bekannt. Die vorliegende Erfindung kommt demgemäß bei Gieß-Walz-Anlagen zum Einsatz, die im Endlosbetrieb aus flüssigem Metall ein fertiges Band herstellen. Für derartige Anlagen wird eine Strategie vorgeschlagen, die zum Einsatz kommen kann, wenn beabsichtigt oder unbeabsichtigt eine Unterbrechung des Walzbetriebs im Fertig-Walzwerk stattfindet.The invention relates to a method for producing a metallic strip in a continuous casting roll process, in which first a slab is poured in a casting machine and fed to a downstream in the conveying direction of the strip finishing mill and rolled here. Furthermore, the invention relates to a device for carrying out the method. A generic method or a generic device are off KR 20130053111 A known. The present invention is accordingly used in cast-rolling plants which produce a finished strip from liquid metal in continuous operation. For such systems, a strategy is proposed which can be used if an interruption of the rolling operation in the finishing mill takes place intentionally or unintentionally.

Bekannte Gieß-Walzstraßen konvertieren flüssigen Stahl in einer kompakten Anlage zu Warmband. Dabei werden zunächst Brammen endloser Länge gegossen.Known casting mills convert liquid steel in a compact plant to hot strip. First, slabs of endless length are poured.

Diese Brammen werden mittels Scheren zerteilt, die in Ihren Abmessungen einer gewünschten Warmbundgröße entsprechen. In Wärmeöfen, oftmals als Rollenherdofen ausgeführt, werden die Brammen in der Temperatur konditioniert. Anschließend werden die Brammen einzeln einer Walzstrasse zugeführt und ausgewalzt. Anschließend werden die Bänder in einer Kühlstrecke abgekühlt und aufgehaspelt. Die Bunde verlassen die Walzlinie zur weiteren Verarbeitung.These slabs are cut by means of scissors, which correspond in their dimensions to a desired hot-rolled size. In furnaces, often designed as a roller hearth furnace, the slabs are conditioned in temperature. Subsequently, the slabs are individually fed to a rolling train and rolled. Subsequently, the strips are cooled in a cooling section and reeled. The leagues leave the rolling line for further processing.

Bei dem so genannten Semi-Endlos-Verfahren werden die Brammen so geschnitten, dass zwei oder mehr Bunde aus dieser Bramme erzeugt werden
können. Hinter dem Walzwerk ist zusätzlich eine fliegende Schere angeordnet, die das lange Warmband zerteilt, so dass die gewünschte Bundgröße erreicht wird. Mit diesem Verfahren wird die Anzahl der beim Walzen kritischen Ein- und Ausfädel-Prozesse reduziert, so dass dünnere Warmbänder sicherer erzeugt werden können.In the so-called semi-endless process, the slabs are cut so that two or more bundles are produced from this slab
can. Behind the rolling mill, flying scissors are additionally arranged, which cuts the long hot strip, so that the desired waist size is achieved. This process reduces the number of threading and unthreading processes that are critical to rolling, allowing thinner hot strips to be produced more safely.

Beiden Prozessformen ist gemein, dass durch das Trennen, insbesondere Schneiden, der Bramme der Gießprozess und der Walzprozess entkoppelt stattfinden können. Die möglichen und notwendigen Prozessgeschwindigkeiten von Gießmaschine und Walzstraße sind somit unabhängig voneinander einstellbar.Both forms of process have in common that by separating, in particular cutting, the slab of the casting process and the rolling process can take place decoupled. The possible and necessary process speeds of casting machine and rolling train are thus independently adjustable.

Durch die Fortschritte in der Gießmaschine und in der Prozessführung, z. B. durch Heizvorrichtungen, ist es heute möglich, auf ein Teilen der Bramme vor dem Walzen zu verzichten. Es wurde ein sog. Voll-Konti-Prozess entwickelt. Die Bramme läuft hierbei nach der Durcherstarrung unzerteilt in die Walzstraße ein, während in der Gießmaschine noch am selben Gießstrang gegossen wird. Das Zerteilen des Materials zu Bunden findet erst an der fliegenden Schere hinter der Walzstraße statt.Due to the progress in the casting machine and in the process management, z. B. by heaters, it is possible today to dispense with dividing the slab before rolling. A so-called full-conti-process was developed. The slab runs here after solidification in one piece in the rolling mill, while cast in the casting machine still on the same cast strand. The division of the material into coils takes place only at the flying shears behind the rolling mill.

Es kommen also bei besagtem Voll-Konti-Prozess regelmäßig Betriebszustände vor, bei denen das Material von der Gießmaschine bis zum Haspel noch als ein physikalischer Körper verbunden ist. Der ganze Prozess findet somit kontinuierlich oder endlos statt.So it comes in said full-Konti process regularly operating conditions in which the material from the caster to the reel is still connected as a physical body. The whole process takes place continuously or endlessly.

Störungen kommen bei Anlagen dieser Größenordnung, die sich über mehrere hundert Meter erstrecken können, sporadisch vor. So muss z. B. bei Fehlfunktionen in der Warmbandstraße, an einer Schere usw. der Produktionsprozess unterbrochen werden. Die Anlage wird dann gestoppt und alle Bewegungen des Bandes bzw. der Bramme kommen zum Stillstand. Dabei kann es passieren, dass über die ganze Anlagenlänge ein unzerteilter Strang mit
unterschiedlichen Bearbeitungsgraden liegt. Dadurch, dass in den verschiedenen Aggregaten (Gießmaschine, Scheren, Öfen, Walzstraße, Haspel) dieser Strang über eine Länge von 100 m und mehr liegt, ist eine Bewegung unabhängig voneinander nicht möglich.Interferences occur sporadically in systems of this size, which can extend over several hundred meters. So z. B. in case of malfunction in the hot strip mill, on a pair of scissors, etc. of the production process are interrupted. The system is then stopped and all movements of the belt or slab come to a standstill. It can happen that over the entire plant length an undivided strand with
different degrees of processing. The fact that in the various units (caster, shears, ovens, rolling mill, reel) of this strand over a length of 100 m and more, a movement is not possible independently.

Störungen können grundsätzlich in allen Teilaggregaten auftreten, d. h. im Bereich des Haspels, der fliegende Schere(n), der Fertigstraße, des Rollenherdofen usw. Ein Verwalzer in der Fertigstraße z. B. durch Bänderriss zwischen den letzten beiden Gerüsten, führt so innerhalb kürzester Zeit zu einem Materialstau zwischen diesen Gerüsten, der nur durch spätere manuelle Tätigkeiten beseitigt werden kann. Hierzu sind zeitintensive Arbeiten notwendig mit anschließender Inspektion und ggf. Instandsetzung der Anlagenteile.Disturbances can basically occur in all sub-aggregates, ie. H. in the area of the reel, the flying shear (s), the finishing train, the roller hearth furnace, etc. A Verwalzer in the finishing mill z. As by torn ligament between the last two scaffolding, so within a very short time leads to a jam between these scaffolding, which can only be eliminated by later manual activities. This requires time-consuming work with subsequent inspection and, if necessary, repair of the plant components.

Der Steuermann oder das Automationssystem stoppt im Störungsfall die Walzung. Die Gerüste werden im Allgemeinen in kürzest möglicher Zeit aufgefahren, alle Antriebe werden angehalten und der Strang kommt zum Stillstand. Da die Bramme bis zur Kokille nicht geteilt ist, gibt es Fälle, in denen auch zwangsläufig die Gießmaschine zum Stillstand kommt.The helmsman or the automation system stops rolling in the event of a fault. The scaffolds are generally driven in the shortest possible time, all drives are stopped and the strand comes to a standstill. Since the slab is not divided up to the mold, there are cases where inevitably the casting machine comes to a standstill.

Dieses Aggregat ist hierbei besonders kritisch zu sehen. Wenn der Stillstand zu lange dauert, erstarrt der Stahl in der Kokille und kann nur noch sehr aufwendig entfernt werden bzw. nur unter Beschädigung der Kokille. Ein unkontrolliertes Auffahren der Kokille und der Strangführung würde in der Regel zu einem Strangdurchbruch führen, so dass der flüssige Stahl sich über das Aggregat ergießt und erhebliche Beschädigungen nach sich zieht. Insbesondere die Strangführungsrollen sind empfindlich gegen thermische Überlastung bei längerem Stillstand.This unit is particularly critical to see. If the standstill takes too long, the steel solidifies in the mold and can only be removed very expensive or only with damage to the mold. An uncontrolled raising of the mold and the strand guide would usually lead to a strand breakthrough, so that the liquid steel pours over the aggregate and causes considerable damage. In particular, the strand guide rollers are sensitive to thermal overload during prolonged standstill.

Das Entfernen des erstarrten Gießstrangs aus der Gießmaschine ist sehr zeitaufwendig und oftmals nur durch manuelles Zerteilen (z. B. Brennschneiden) möglich. Hierzu sind Kranarbeiten erforderlich und die Kokille und ggf. Teile der Stranggussanlage müssen ausgewechselt werden. Dies führt zu hohen Stillstandszeiten und Produktionseinbußen und ist zudem mit manuellen Operationen verbunden.The removal of the solidified casting strand from the casting machine is very time-consuming and often only possible by manual cutting (eg flame cutting). For this purpose, crane work is required and the mold and possibly parts of Continuous casting plant must be replaced. This leads to high downtimes and production losses and is also associated with manual operations.

Die EP 2 259 886 B1 schlägt diesbezüglich vor, einen Schnitt in das Band einzubringen, den in Förderrichtung vorneliegenden Bandfuß nach oben zu biegen und das nachfolgende Band zu häckseln. Dies setzt aber konzeptbedingt voraus, dass das nachfolgende Bandmaterial noch in Bewegung ist. Weitere bzw. ähnliche Lösungen sowie auch spezielle Aspekte des Zerteilens der Bramme bzw. des Bandes werden in der EP 0 625 383 B1 , in der DE 198 56 767 A1 , in der DE 42 20 424 A1 , in der JP 0122 4102 A , in der JP 0527 7539 A , in der JP 6315 7750 A und in der JP 2001 276 910 A thematisiert. Zum Stand der Technik sind auch noch die KR 2013 0053111 A und die KR 2013 0053110 A zu nennen, die hinter einer Trennvorrichtung für das Band einen Bandspeicher einsetzen.The EP 2 259 886 B1 proposes in this regard to introduce a cut in the band, to bend the band foot which protrudes in the conveying direction upwards and to chop the following band. However, this requires conceptually that the following strip material is still in motion. Other or similar solutions as well as special aspects of the division of the slab or the band are in the EP 0 625 383 B1 , in the DE 198 56 767 A1 , in the DE 42 20 424 A1 , in the JP 0122 4102 A , in the JP 0527 7539 A , in the JP 6315 7750 A and in the JP 2001 276 910 A addressed. The state of the art are still the KR 2013 0053111 A and the KR 2013 0053110 A to name a tape storage behind a separator for the tape.

Demgemäß darf beim kontinuierlichen Gießbetrieb in einer Endlosanlage auch bei einem geplanten Walzenwechsel der Betrieb möglichst nicht unterbrochen werden. Der Strang wird abgetrennt, das abgetrennte Band wird ausgewalzt. Anschließend werden aus dem Strang Platten geschnitten und diese mittels einer Austragevorrichtung als Schrott abtransportiert.Accordingly, during continuous casting operation in an endless system, the operation should not be interrupted as much as possible even during a planned roll change. The strand is separated, the severed band is rolled out. Subsequently, slices are cut from the strand and transported away by means of a discharge device as scrap.

Der hinter der Schere gegebenenfalls gestapelte Schrott (s. hierzu die genannte EP 2 259 886 B1 ) kann dabei nicht unbedingt direkt in den Ofen zurückgegeben werden. Der Schrott muss dann vielmehr in einem Zwischenschritt zerteilt werden. Bei einer Störung in der Anlage kann die Schere nicht rückwärts häckseln. Ferner ist keine Schrottrutsche vorhanden.If necessary, the scrap stacked behind the scissors (see here EP 2 259 886 B1 ) can not necessarily be returned directly into the oven. The scrap must then rather be divided in an intermediate step. In the event of a malfunction in the system, the scissors can not chop backwards. Furthermore, no scrap chute is present.

Die Erfindung liegt die Aufgabe zugrunde, die Produktionslinie nach dem beabsichtigten (beispielsweise bedingt durch einen Walzenwechsel) oder unbeabsichtigten Auftreten einer Produktionsunterbrechung in der Fertig-Walzstraße sicher, schnell und wirtschaftlich sowie bevorzugt teil- oder
vollautomatisch wieder in den regulären Betriebszustand zu versetzen. Aus der Kokille und weiter aus der Gießmaschine austretender Stahl bzw. die hieraus entstehende Brammen bzw. das hieraus gegossene Band soll möglichst schnell entfernt werden, um Beschädigungen und Stillstandszeiten zu minimieren. Dabei soll das aus der Anlage entfernte Material (d. h. der Schrott) so aufbereitet werden, dass eine möglichst einfache Weiterverarbeitung (d. h. ein Einschmelzen) möglich wird; somit soll das Wiederveniverten von Schrott in einfacher Weise ermöglicht werden. Dabei wird eine kompakte Bauweise der Anlage angestrebt. Ziel ist es weiterhin, dass in einfacher Weise kleine Schrottstücke erzeugt werden, die direkt wieder eingeschmolzen werden können.The invention is based on the object, the production line after the intended (for example, due to a roll change) or unintentional occurrence of production stoppage in the finishing mill safely, quickly and economically and preferably partially or
Fully automatically return to the normal operating state. Steel emerging from the mold and further out of the casting machine or the slabs or the strip cast therefrom should be removed as quickly as possible in order to minimize damage and downtimes. In this case, the material removed from the plant (ie the scrap) is to be processed so that the simplest possible further processing (ie a melting) is possible; Thus, the Wiedererveniverten of scrap is to be made possible in a simple manner. Here, a compact design of the system is desired. The goal is also that in a simple way small pieces of scrap are generated, which can be remelted directly.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass im Falle einer geplanten oder ungeplanten Produktionsunterbrechung im Fertig-Walzwerk folgende Schritte ausgeführt werden:

  1. a) Durchschneiden des Bandes an einer Stelle zwischen der Gießmaschine und dem Fertig-Walzwerk mittels einer Trennvorrichtung;
  2. b) Fördern des dem Schnitt in Förderrichtung nachfolgenden Teils des Bandes in einen Bandspeicher mittels eines Treibers, wobei der Treiber in Förderrichtung hinter der Trennvorrichtung angeordnet ist;
  3. c) Nochmaliges Durchschneiden des Bandes mittels der Trennvorrichtung und Zerhäckseln des in Förderrichtung nachfolgenden Teils des Bandes mittels der Trennvorrichtung in Teile vorzugsweise mit definierter Längserstreckung;
  4. d) Zerhäckseln des gespeicherten Bandabschnitts in Teile vorzugsweise mit definierter Längserstreckung, wobei hierbei ein Rückfördern des sich im Bandspeicher befindlichen Bandes entgegen der Förderrichtung mittels des Treibers zur Trenneinrichtung erfolgt, wo das Zerhäckseln des gespeicherten Bandabschnitts mittels der Trenneinrichtung stattfindet.
The solution of this object by the invention is characterized in that the following steps are carried out in the case of a planned or unplanned production interruption in the finishing mill:
  1. a) cutting the strip at a location between the caster and the finishing mill by means of a separator;
  2. b) conveying the section of the strip following the cut in the conveying direction into a strip store by means of a driver, wherein the driver is arranged in the conveying direction behind the separating device;
  3. c) repeated cutting of the strip by means of the separating device and chopping the downstream part of the strip in the conveying direction by means of the separating device into parts, preferably with a defined longitudinal extent;
  4. d) chopping the stored band section into parts, preferably with a defined longitudinal extension, whereby in this case a return conveying of the band located in the band memory against the conveying direction takes place by means of the driver to the separator, where the Zerhäckseln the stored band section takes place by means of the separator.

Dabei werden die Teile, die bei den Schritten c) und d) erzeugt werden, bevorzugt in einen Sammelraum abgeführt.In this case, the parts which are produced in steps c) and d) are preferably removed into a collecting space.

Die obigen Schritte a) bis d) werden dabei bevorzugt in dieser zeitlichen Reihenfolge durchgeführt.The above steps a) to d) are preferably carried out in this chronological order.

Bei obigem Schritt c) können Bandabschnitte mit einer Länge in Förderrichtung zwischen 0,1 m und 5 m geschnitten werden.In the above step c), tape sections with a length in the conveying direction between 0.1 m and 5 m can be cut.

Die Vorrichtung zur Herstellung eines metallischen Bandes im kontinuierlichen Gießwalzverfahren, umfassend eine Gießmaschine und ein in Förderrichtung des Bandes nachgelagertes Fertig-Walzwerk zeichnet sich erfindungsgemäß dadurch aus, dass zwischen der Gießmaschine und dem Fertig-Walzwerk eine Trenneinrichtung angeordnet ist und dass in Förderrichtung der Trenneinrichtung nachfolgend ein Bandspeicher für die Aufnahme eines Bandabschnitts angeordnet ist, wobei in Förderrichtung hinter der Trenneinrichtung und vor dem Bandspeicher ein Treiber angeordnet ist, der zum Fördern des Bandes in den Bandspeicher ausgebildet ist, und wobei der Treiber auch zum Fördern des Bandes zurück zur Trenneinrichtung ausgebildet ist.The apparatus for producing a metallic strip in a continuous casting roll process, comprising a casting machine and a finished rolling mill downstream in the conveying direction of the strip, is characterized according to the invention in that a separating device is arranged between the casting machine and the finish rolling mill and that following in the conveying direction of the separating device a tape storage is arranged for receiving a tape portion, wherein in the conveying direction behind the separating device and before the tape storage, a driver is arranged, which is designed for conveying the tape in the tape storage, and wherein the driver is also designed to convey the tape back to the separating device ,

Die Trenneinrichtung ist bevorzugt eine Trommelschere. Möglich ist aber auch der Einsatz einer Pendelschere oder einer beweglichen Torschere.The separating device is preferably a drum shears. But it is also possible to use a pendulum scissors or a movable scissors.

Unterhalb der Trenneinrichtung ist bevorzugt ein Sammelraum für Bandteile angeordnet. Zwischen der Trenneinrichtung und dem Sammelraum kann eine Schrottrutsche angeordnet sein.Below the separating device, a collecting space for strip parts is preferably arranged. A scrap chute may be arranged between the separating device and the collecting space.

In Förderrichtung vor der Trenneinrichtung kann ein weiterer Treiber angeordnet sein.In the conveying direction before the separator, a further driver may be arranged.

In Förderrichtung vor der Trenneinrichtung kann weiterhin auch ein Ofen angeordnet sein.In the conveying direction in front of the separating device may continue to be arranged a furnace.

Eingesetzt werden kann das Konzept insoweit bei allen Anlagenkonzepten mit beliebigen Kombinationen aus Gießmaschine, Vorwalzwerk, Ofen, Zwischenwalzwerk und Fertigwalzwerk.The concept can be used in all plant concepts with any combination of casting machine, roughing mill, furnace, intermediate rolling mill and finishing mill.

Demgemäß ist erfindungsgemäß vorgesehen, dass insbesondere eine Häcksel-Schere in Kombination mit einem Bandspeicher zum Einsatz kommt. Bei einer Störung bzw. einem Nothalt oder auch bei einer geplanten Unterbrechung des Betriebs beispielsweise aufgrund eines Walzenwechsels in der Fertigstraße wird das von der Gießmaschine ankommende Band in dem Bandspeicher zwischengespeichert. Vorzugsweise durchtrennt eine Trommelschere das Band. Ein Treiber hinter der Trenneinrichtung fördert das Band in den Bandspeicher. Somit entsteht eine kurze Lücke. Die Trenneinrichtung zerteilt das ankommende Band in Schrottstücke, die bevorzugt über eine Schrottrutsche in einen Schrottentsorgungsbereich rutschen.Accordingly, the invention provides that, in particular, a chopper scissors in combination with a tape storage is used. In the event of a malfunction or an emergency stop or even during a planned interruption of operation, for example due to a roll change in the finishing train, the strip arriving from the casting machine is temporarily stored in the strip store. Preferably, a drum shears severed the tape. A driver behind the separator promotes the tape in the tape storage. This creates a short gap. The separating device divides the incoming strip into scrap pieces, which preferably slide over a scrap chute into a scrap disposal area.

Eine Trenneinrichtung hinter der Gießmaschine trennt den Strang ab. Das verbleibende Band wird beschleunigt und die Trenneinrichtung (Trommelschere) zerteilt es. Der Strang, der jetzt gegossen wird, wird mit der Trenneinrichtung hinter der Gießmaschine in Platten geschnitten und mittels einer Austragevorrichtung abgeschoben.A separator behind the caster separates the strand. The remaining belt is accelerated and the separator (drum shears) parts it. The strand, which is now being poured, is cut into plates with the separating device behind the casting machine and pushed off by means of a discharge device.

Der Stau in der Fertigstraße wird entfernt, beispielsweise wird er manuell entsorgt. Das Band zwischen der Fertigstraße und der Trenneinrichtung (Trommelschere) kann dann rückwärts (d. h. gegen die Förderrichtung) aus dem Bandspeicher durch die Trenneinrichtung gefahren und von dieser gehäckselt werden.The jam in the finishing train is removed, for example, it is disposed of manually. The strip between the finishing train and the separating device (drum shears) can then be moved backwards (ie against the conveying direction) from the tape storage by the separator and chopped by this.

Ist dies erfolgt, können die Gießmaschine und die gesamte Anlage wieder in den Normalbetrieb übergehen.Once this has been done, the casting machine and the entire system can return to normal operation.

Die Schrottstücke können direkt wieder eingeschmolzen werden. Der Bereich zwischen der Trommelschere und der Fertigstraße kann rückwärts geräumt werden. Die vorgeschlagene Bauweise ist kompakt und kann energiesparend arbeiten. Der Bandspeicher kann auch als Zugreglung genutzt werden.The scrap pieces can be remelted directly. The area between the drum shears and the finishing line can be cleared backwards. The proposed construction is compact and can save energy. The tape storage can also be used as Zugreglung.

Eine Trommelschere kann den Schrott schnell und effizient entsorgen.A drum shears can dispose of the scrap quickly and efficiently.

In the drawing, an embodiment of the invention is shown. Show it:
Fig. 1
schematically a casting-rolling plant for the production of a steel strip and
Fig. 2
an enlarged view of a separator in the form of a pair of scissors, which is arranged between the casters and the finishing mill of the plant.

In Fig. 1 ist ein Beispiel für eine Gieß-Walz-Anlage skizziert, die als Voll-Konti-Anlage ausgebildet ist und die als zentrale Elemente eine Gießmaschine 2 und ein Fertig-Walzwerk 3 umfasst. Hinter der Gießmaschine 2 ist ein Vorwalzwerk 12 vorgesehen, an das sich - je nach Anlagenkonzept - ein Ofen 11 (Verbindungsrollgang mit Erwärmfunktion) anschließt. Hinter dem Ofen 11 folgt das Fertig-Walzwerk 3. Hinter dem Fertig-Walzwerk 3 befindet sich eine Kühlstrecke 13 und eine Trenneinrichtung in Form einer fliegenden Schere 14. In Förderrichtung F schließt sich dann mindestens ein Haspel 15 und 16 an.In Fig. 1 an example of a casting-rolling plant is sketched, which is designed as Voll-Konti-plant and which includes a casting machine 2 and a finish rolling mill 3 as central elements. Behind the caster 2, a roughing mill 12 is provided, to which - depending on the system concept - a furnace 11 (connecting roller table with heating function) connects. Behind the furnace 11 follows the finished rolling mill 3. Behind the finish rolling mill 3 is a cooling section 13 and a separator in the form of a flying shears 14. In the conveying direction F, then at least one reel 15 and 16 follows.

Zwischen dem Vorwalzwerk 12 und dem Ofen 11 ist eine Trenneinrichtung in Form einer Schere 17 für das Band 1 angeordnet. Eine weitere Schere 5 (Trennvorrichtung) befindet sich zwischen dem Ofen 11 und dem Fertig-Walzwerk 3 an einer Stelle 4. Schließlich ist noch die weitere Schere (Trennvorrichtung) 14 hinter der Kühlstrecke 13 und vor den Haspeln 15, 16 angeordnet. In Fig. 1 ist noch eine Schere (Trenneinrichtung) 17 zu erkennen, die hinter der Gießmaschine 2 und dem Ofen 11 angeordnet ist.Between the roughing mill 12 and the furnace 11, a separator in the form of a pair of scissors 17 for the band 1 is arranged. Another pair of scissors 5 (separating device) is located between the furnace 11 and the finished rolling mill 3 at a point 4. Finally, the other pair of scissors (separating device) 14 behind the cooling section 13 and in front of the reels 15, 16 is arranged. In Fig. 1 is still a pair of scissors (separator) 17 to recognize, which is located behind the casting machine 2 and the furnace 11.

An der Stelle 4 ist - wie erwähnt - die weitere Trenneinrichtung (Schere) 5 angeordnet, die in Fig. 2 näher dargestellt ist. Der in Fig. 2 dargestellte Anlagenteil zeigt weiterhin, dass in Förderrichtung F hinter der Trenneinrichtung 5 ein Bandspeicher 6 angeordnet ist, der nur schematisch angedeutet ist. Das Band 1, das aus dem Ofen 11 kommt, wird durch einen Treiber 10 gefördert. Mittels der optional als Trommelschere ausgebildeten Trenneinrichtung 5 kann das Band 1 durchtrennt bzw. durchgeschnitten werden. Mittels eines weiteren Treibers 7 kann das abgetrennte Band 1 dann in den Bandspeicher 6 gefördert werden.At the point 4 - as mentioned - the further separator (scissors) 5 is arranged in Fig. 2 is shown in more detail. The in Fig. 2 shown plant part further shows that in the conveying direction F behind the separator 5, a tape storage 6 is arranged, which is indicated only schematically. The tape 1 coming out of the oven 11 is conveyed by a driver 10. By means of the optionally designed as a drum shears separating device 5, the band 1 can be cut or cut through. By means of a further driver 7, the separated tape 1 can then be conveyed into the tape storage 6.

Wie oben erläutert wurde, wird bei einer Produktionsunterbrechung im Fertig-Walzwerk 3 das Band 1 an der Stelle 4 von der Trenneinrichtung 5 durchgeschnitten. Es erfolgt dann ein Fördern des Teils des Bandes 1, der sich in Förderrichtung F hinter der Trenneinrichtung 5 befindet, in den Bandspeicher 6, wofür der Treiber 7 eingesetzt wird. Nach nochmaligem Durchtrennen bzw. Durchschneiden des Bandes 1 mittels der Trenneinrichtung 5 kann dann ein Zerhäckseln des Bandabschnitts vorgenommen werden, der aus der Gießmaschine 2 nachfolgt. Das Band wird in an sich bekannter Weise (s. hierzu die EP 2 259 886 B1 ) in Teile vorzugsweise mit definierter Länge geschnitten und über eine Schrottrutsche 9 in einen Sammelraum 8 abgeführt.As explained above, in a production stoppage in the finishing mill 3, the strip 1 is cut through at the position 4 by the separator 5. There is then a conveying of the part of the belt 1, which is located in the conveying direction F behind the separating device 5, in the tape storage 6, for which the driver 7 is used. After again cutting through or cutting through the strip 1 by means of the separating device 5, a chopping of the strip section can then be carried out, which follows from the casting machine 2. The tape is in a conventional manner (see EP 2 259 886 B1 ) cut into parts, preferably with a defined length and discharged via a scrap chute 9 into a collecting space 8.

Ist dieser Vorgang abgeschlossen, wird das sich im Bandspeicher 6 befindliche Band 1 entgegen der Förderrichtung F mittels des Treibers 7 zur Trenneinrichtung 5 rückgefördert, mittels der Trenneinrichtung 5 zerhäckselt und gleichermaßen in den Sammelraum 8 abgeführt.If this process is completed, the band 1 located in the band memory 6 is counter to the conveying direction F by means of the driver 7 to the separator 5 fed back, shredded by means of the separator 5 and equally discharged into the collection chamber 8.

Natürlich kann das vorgeschlagene Verfahren auch bei einem hiervon abweichenden Anlagenkonzept einer Gieß-Walz-Anlage eingesetzt werden.Of course, the proposed method can also be used in a deviating plant concept of a casting-rolling plant.
