Abstract

The invention describes an installation for rolling out hot wide strip from continuously cast thin slabs by means of a continuous finishing train 19 which operates with three casting machines or casting lines 1, 2, 3 positioned ahead of it, the central casting machine or casting line 2 being in line with the finishing train 19.

Description

Die Erfindung betrifft eine Anlage zum Auswalzen von Warmbreitband aus stranggegossenen Dünnbrammen mittels einer kontinuierlichen Fertigstraße.The invention relates to a system for rolling out hot wide strip from continuously cast thin slabs by means of a continuous finishing train.

In neu entwickelten Produktionsanlagen werden als Vormaterial für die Fertigstraße stranggegossene Dünnbrammen eingesetzt, die eine Dicke von weniger als 70 mm, vorzugsweise von 50 mm, haben. Die Dünnbrammen werden dabei von einem in einer Stranggießmaschine erzeugten Gußstrang abgetrennt, und zwar jeweils mit einer Länge, die dem geforderten Coil-Gewicht für das fertige Warmbreitband entspricht.In newly developed production plants, continuously cast thin slabs are used as raw material for the finishing train, which have a thickness of less than 70 mm, preferably 50 mm. The thin slabs are separated from a cast strand produced in a continuous casting machine, each with a length that corresponds to the required coil weight for the finished hot wide strip.

Zur Aufrechterhaltung der nötigen Walztemperatur werden die Dünnbrammen einem Ofen zugeführt, welcher vorzugsweise als Rollenherdofen ausgeführt ist und dabei gleichzeitig als Transportsystem von der Stranggießmaschine zur Fertigstraße benutzt werden kann.In order to maintain the required rolling temperature, the thin slabs are fed to a furnace, which is preferably designed as a roller hearth furnace and at the same time can be used as a transport system from the continuous casting machine to the finishing train.

Die derzeitig erreichbaren Gießgeschwindigkeiten von Stranggießmaschinen für Dünnbrammen-Strangguß sind jedoch relativ gering, so daß eine Kapazitätsauslastung der nachgeordneten, kontinuierlichen Fertigstraße nicht erreicht werden kann.However, the currently achievable casting speeds of continuous casting machines for thin slab continuous casting are relatively low, so that a capacity utilization of the downstream continuous finishing train cannot be achieved.

Immerhin liegt die Einzugsgeschwindigkeit der kontinuierlichen Warmbreitband-Fertigstraßen etwa um den Faktor 2 bis 4 höher als die Gießgeschwindigkeit der für den Dünnbrammen-Strangguß geeigneten Gießmaschinen.After all, the feed speed of the continuous hot wide strip finishing lines is about a factor of 2 to 4 higher than the casting speed of the casting machines suitable for thin slab casting.

Es ist deshalb bereits vorgeschlagen worden, eine kontinuierliche Warmbreitband-Fertigstraße mit zwei parallelen Stranggießmaschinen zusammenarbeiten zu lassen, derart, daß Dünnbrammen abwechselnd von jedem der beiden Gußstränge abgetrennt und anschließend jeweils der Warmbreitband-Fertigstraße zur Auswalzung zugeführt werden. Mit Hilfe zweier Längs/Quer/Längs-Transportsysteme, sogenannter Fähren, werden die Dünnbrammen aus der jeweiligen Gießlinie bewegt und mit der Warmbreitband-Fertigstraße in Fluchtlage gebracht, damit sie dann in diese eingezogen werden können.It has therefore already been proposed to have a continuous hot-rolled strip finishing train work with two parallel continuous casting machines in such a way that thin slabs are alternately separated from each of the two cast strands and then each is fed to the hot-rolled strip finishing train for rolling. With the help of two longitudinal / transverse / longitudinal transport systems, so-called ferries, the thin slabs are moved out of the respective casting line and brought into alignment with the hot strip mill so that they can then be drawn into it.

Eine solche Auslegung der Anlagen zum Auswalzen von Warmbreitband aus stranggegossenen Dünnbrammen führt zwar schon zu einer deutlichen Verbesserung hinsichtlich der Auslastung der Fertigstraße und erhöht dadurch die Wirtschaftlichkeit der Gesamtanlage. Eine optimale Auslastung derselben ist jedoch auch hierdurch noch nicht erreichbar.Such a design of the systems for rolling out hot wide strip from continuously cast thin slabs already leads to a significant improvement in the utilization of the finishing train and thereby increases the efficiency of the overall system. However, optimal utilization of the same is still not possible.

Die Erfindung zielt nun auf eine weitere Verbesserung der Auslastung für die Warmbreitband-Fertigstraße und damit auch der Wirtschaftlichkeit für die Gesamtanlage ab und liegt dabei darin, daß der Fertigstraße drei nebeneinander laufende, einsträngige Gießmaschinen bzw. Gießlinien vorgeordnet sind, von denen die mittlere mit der Fertigstraße fluchtet, daß von jedem der drei Gießstränge in im allgemeinen zeitversetzter Aufeinanderfolge einzelne Dünnbrammen abtrennbar sind, daß jede Dünnbramme auf eines von zwei den Gießmaschinen bzw. Gießlinien nachgeordneten und der Fertigstraße vorgeordneten sowie nebeneinander vorgesehenen Längs/Quer/ Längs-Transportsystemen überführbar ist, daß dabei die beiden Längs/Quer/Längs-Transportsysteme auf einen seitlichen Abstand voneinander einstellbar sind, der dem Abstand zwischen zwei benachbarten Gießmaschinen bzw. Gießlinien entspricht, daß beide Längs/Quer/Längs-Transportsysteme synchron miteinander oder untereinander gekoppelt über eine Strecke querverfahrbar sind, nach deren Durchlaufen entweder das eine oder das andere Längs/Quer/Längs-Transportsystem sowohl mit der mittleren Gießmaschine bzw. Gießlinie als auch mit der Fertigstraße in Fluchtlage steht, und daß der Fertigstraße jeweils von dem mit ihr in Fluchtlage stehenden Längs/Quer/Längs-Transportsystem die darauf befindliche Dünnbramme zuführbar ist, während gleichzeitig auf die jeweils mit einer seitlichen Gießmaschine bzw. Gießlinie fluchtende Längs/Quer/Längs-Transportvorrichtung die nachfolgend auszuwalzende Dünnbramme übergebbar ist.The invention is now aimed at a further improvement in the utilization of the hot strip finishing mill and thus the economy for the entire system, and is that the finishing train is preceded by three single-strand casting machines or casting lines running side by side, the middle of which with the Finishing line is aligned so that individual thin slabs can be separated from each of the three casting strands in a generally time-delayed sequence, that each thin slab is placed on one of two longitudinal / transverse / downstream of the casting machine or casting lines and upstream of the finishing line and provided next to one another Longitudinal transport systems can be transferred such that the two longitudinal / transverse / longitudinal transport systems can be set to a lateral distance from one another which corresponds to the distance between two adjacent casting machines or casting lines, that both longitudinal / transverse / longitudinal transport systems are synchronous with one another or with one another coupled are traversable over a distance, after passing through either one or the other longitudinal / transverse / longitudinal transport system with the middle casting machine or casting line as well as with the finishing train is in alignment, and that the finishing train in each case with it in Longitudinal / transverse / longitudinal transport system in the aligned position, the thin slab located thereon can be fed, while at the same time the thin slab subsequently to be rolled out can be transferred to the longitudinal / transverse / longitudinal transport device aligned with a lateral casting machine or casting line.

Durch eine solche Auslegung der Anlage zum Auswalzen von Warmbreitband aus stranggegossenen Dünnbrammen ist eine wesentliche Verkürzung der Taktzeiten zur Beschickung der Warmbreitband-Fertigstraße mit Dünnbrammen erreichbar, wenn die Bedingungen eingehalten werden,

  • daß die Ladezeit für eine von einem Gießstrang abgetrennte Dünnbramme in das Längs/Quer/Längs-Transportsystem der Entladezeit einer solchen Dünnbramme aus dem Längs/Quer/ Längs-Transportsystem entspricht und
  • daß die Walzzeit für die Auswalzung einer Dünnbramme jederzeit größer ist als die Fahrzeit der Längs/Quer/Längs-Transportsysteme zuzüglich dieser Lade-bzw. Entladezeit.
With such a design of the plant for rolling out hot wide strip from continuously cast thin slabs, the cycle times for feeding thin strip into the hot strip finishing train can be significantly reduced if the conditions are met.
  • that the loading time for a thin slab separated from a casting strand into the longitudinal / transverse / longitudinal transport system corresponds to the unloading time of such a thin slab from the longitudinal / transverse / longitudinal transport system and
  • that the rolling time for rolling out a thin slab is at any time greater than the travel time of the longitudinal / transverse / longitudinal transport systems plus this loading or. Discharge time.

Nach der Erfindung hat es sich dabei als wichtig erwiesen, daß jeder Gießmaschine bzw. Gießlinie vor den Längs/Quer/ Längs-Transportsystemen ein Ofen, ein Ausgleichsbereich und ein Pufferbereich zugeordnet sind, während den Längs/Quer/ Längs-Transportsystemen vor der Fertigstraße ein damit fluchtender Aufnahmeofen nachgeordnet ist.According to the invention, it has proven important that each casting machine or casting line in front of the longitudinal / transverse / longitudinal transport systems an oven, a compensation area and a buffer area is assigned, while the longitudinal / transverse / longitudinal transport systems in front of the finishing train are followed by a receiving furnace that is flush with it.

Ebenso wichtig ist aber auch, daß die Längs/Quer/Längs-Transportsysteme aus beheizbaren Fähren bestehen, die dabei als einen Längstransport enthaltende, quer verfahrbare Öfen, z.B. Rollenherdöfen, ausgelegt werden können.However, it is equally important that the longitudinal / transverse / longitudinal transport systems consist of heatable ferries, which in the process are used as transverse transporting ovens containing a longitudinal transport, e.g. Roller hearth furnaces can be designed.

Auch Ofen, Ausgleichsbereich und Pufferbereich hinter jeder Gießmaschine bzw. Gießlinie können erfindungsgemäß von einem ortsfesten Rollenherdofen gebildet werden.The furnace, compensation area and buffer area behind each casting machine or casting line can also be formed according to the invention by a fixed roller hearth furnace.

Selbstverständlich sind die Transportgeschwindigkeiten aller zwischen den Gießmaschinen bzw. Gießlinien und der Warmbreitband-Fertigstraße vorgesehenen Längstransportsysteme innerhalb des einerseits durch die Gießgeschwindigkeit in den einzelnen Gießmaschinen bzw. Gießlinien und andererseits durch die Einzugsgeschwindigkeit der Warmbreitband-Fertigstraße bestimmten Bereichs so regelbar, daß sich zwischen der aufeinanderfolgenden Einführung zweier Dünnbrammen in die Warmbreitband-Fertigstraße Pufferzeiten herbeiführen lassen, die bspw. für die Durchführung von Walzenwechsel-Operationen ausreichend sind. Die Pufferspeicherung von Dünnbrammen kann in diesem Falle über den gesamten Abstandsbereich zwischen den Gießmaschinen bzw. Gießlinien und der Warmbreitband-Fertigstraße bewirkt werden, weil dieser insgesamt, also auch im Bereich der Längs/Quer/Längs-Transportsysteme bzw. Fähren von die Walztemperatur aufrechterhaltenden Öfen bzw. Heizvorrichtungen überbrückt ist.Of course, the transport speeds of all the longitudinal transport systems provided between the casting machines or casting lines and the hot-rolled strip finishing train can be controlled within the range determined on the one hand by the casting speed in the individual casting machines or casting lines and on the other hand by the pull-in speed of the hot-rolling strip finishing train so that there is a gap between the successive Introduction of two thin slabs into the hot-rolled strip finishing line, which allows for buffer times that are sufficient, for example, to carry out roll change operations. In this case, the buffer storage of thin slabs can be effected over the entire distance between the casting machines or casting lines and the hot-rolled strip finishing train, because this overall, i.e. also in the area of the longitudinal / transverse / longitudinal transport systems or ferries of furnaces that maintain the rolling temperature or heating devices is bridged.

In der Zeichnung ist die erfindungsgemäße Anlage zum Auswalzen von Warmbreitband aus stranggegossenen Dünnbrammen in einem Ausführungsbeispiel schematisch vereinfacht dargestellt. Es zeigen

In the drawing, the plant according to the invention for rolling out hot wide strip from continuously cast thin slabs is shown in a schematically simplified manner in one exemplary embodiment. Show it
Figure 1

Figures 2 to 4
reproduce the same system in the operating state during different, consecutive work phases.

In sämtlichen Figuren der Zeichnung ist zu sehen, daß drei Einstrang-Gießmaschinen bzw. Gießlinien 1, 2 und 3 nebeneinander aufgestellt sind.In all the figures of the drawing it can be seen that three single-strand casting machines or casting lines 1, 2 and 3 are set up side by side.

Der Gießmaschine bzw. Gießlinie 1 ist in Fluchtlage ein Ofen 4, ein Ausgleichsbereich 7 und ein Pufferbereich 10 nachgeordnet. In Fluchtlage mit der Gießmaschine bzw. Gießlinie 2 befindet sich ein Ofen 5, ein Ausgleichsbereich 8 und ein Pufferbereich 11, während in Fluchtlage mit der Gießmaschine bzw. Gießlinie 3 ein Ofen 6, ein Ausgleichsbereich 9 und ein Pufferbereich 12 vorgesehen ist.A furnace 4, a compensation area 7 and a buffer area 10 are arranged downstream of the casting machine or casting line 1 in the aligned position. In the aligned position with the casting machine or casting line 2 there is an oven 5, a compensation area 8 and a buffer area 11, while in the aligned position with the casting machine or casting line 3 an oven 6, a compensation area 9 and a buffer area 12 are provided.

Jeder Ofen 4 bzw. 5 bzw. 6 ist mit dem ihm nachgeordneten Ausgleichsbereich 7 bzw. 8 bzw. 9 und Pufferbereich 10 bzw. 11 bzw. 12 als ein in Längsrichtung durchgehender Rollenherdofen 13 bzw. 14 bzw. 15 ausgeführt, der praktisch einen durchgehenden Längstransport bildet. Hinter den drei Rollenherdöfen 13, 14, 15 bzw. Längstransporten sind zwei sogenannte Fähren aufgebaut, deren jede als kombiniertes Längs/ Quer/Längs-Transportsystem arbeiten kann.Each oven 4 or 5 or 6 is designed with the compensation area 7 or 8 or 9 and buffer area 10 or 11 or 12 downstream thereof as a continuous roller hearth oven 13 or 14 or 15, which is practically a continuous one Longitudinal transport forms. Behind the three roller hearth furnaces 13, 14, 15 or longitudinal transports, two so-called ferries are built, each of which can work as a combined longitudinal / transverse / longitudinal transport system.

Wiederum im Anschluß an diese Fähren 16 und 17 ist in Fluchtlage mit der mittleren Gießmaschine bzw. Gießlinie 2 und dem mittleren Rollenherdofen bzw. Längstransport 14 ein Aufnahmeofen 18 erstellt, an den sich die Warmbreitband-Fertigstraße 19, wiederum in Fluchtlage, anschließt.Again in connection with these ferries 16 and 17, a receiving furnace 18 is created in the escape position with the middle casting machine or casting line 2 and the middle roller hearth furnace or longitudinal transport 14, to which the hot strip mill 19, again in the escape position, connects.

Jede der Gießmaschinen bzw. Gießlinien 1, 2 und 3 ist zur kontinuierlichen Herstellung eines - der Einfachheit halber nur angedeuteten - Gußstranges 21 bzw. 22 bzw. 23 ausgelegt.Each of the casting machines or casting lines 1, 2 and 3 is designed for the continuous production of a cast strand 21 or 22 or 23, which is only indicated for the sake of simplicity.

Der Gußstrang 21 wird unmittelbar hinter der Gießmaschine bzw. Gießlinie 1 fortwährend in Dünnbrammen 24 unterteilt, die allmählich den Rollenherdofen 13 mit dem Ofenbereich 4, den Ausgleichsbereich 7 und dem Pufferbereich 10 durchlaufen. Entsprechende Dünnbrammen 25 werden auch hinter der Gießmaschine bzw. Gießlinie 2 vom Gußstrang 22 abgetrennt und in den Rollenherdofen 14 geführt, wo sie den Ofenbereich 5, den Ausgleichsbereich 8 und den Pufferbereich 11 nacheinander durchlaufen können. Schließlich wird auch unmittelbar hinter der Gießmaschine bzw. Gießlinie 3 der Gußstrang 23 fortwährend in Dünnbrmamen 26 unterteilt, die in den Rollenherdofen 15 gelangen und dort nacheinander durch den Ofenbereich 6, den Ausgleichsbereich 9 und den Pufferbereich 12 laufen.The cast strand 21 is continuously divided immediately behind the casting machine or casting line 1 into thin slabs 24 which gradually pass through the roller hearth furnace 13 with the furnace region 4, the compensation region 7 and the buffer region 10. Corresponding thin slabs 25 are also separated from the cast strand 22 behind the casting machine or casting line 2 and guided into the roller hearth furnace 14, where they can pass through the furnace region 5, the compensation region 8 and the buffer region 11 one after the other. Finally, immediately behind the casting machine or casting line 3, the casting strand 23 is continuously divided into thin slabs 26 which enter the roller hearth furnace 15 and run there one after the other through the furnace region 6, the compensation region 9 and the buffer region 12.

Es sei angenommen, daß nach Inbetriebnahme der in Fig. 1 der Zeichnung gezeigten Gesamtanlage zum Auswalzen von Warmbreitband aus stranggegossenen Dünnbrammen die Gießmaschine bzw. Gießlinie 2 zuerst mit der Ausbringung des Gußstranges 22 begonnen hat, daran anschließend die Gießmaschine bzw. Gießlinie 3 ihren Gußstrang 23 liefert und zuletzt die Gießmaschine bzw. Gießlinie 1 mit der Lieferung ihres Gußstranges 21 begonnen hat.It is assumed that after commissioning of the entire system shown in FIG. 1 of the drawing for the rolling out of hot wide strip from continuously cast thin slabs, the casting machine or casting line 2 first started the application of the casting strand 22, then the casting machine or casting line 3 started its casting strand 23 delivers and finally the casting machine or casting line 1 has started to deliver its cast strand 21.

Folglich wird die erste Dünnbramme 25 vom Gußstrang 22 abgetrennt und im Rollenherdofen 14 durch den Ofenbereich 5, den Ausgleichsbereich 8 und den Pufferbereich 11 transportiert.Consequently, the first thin slab 25 is separated from the cast strand 22 and transported in the roller hearth furnace 14 through the furnace region 5, the compensation region 8 and the buffer region 11.

Da die Gießmaschine bzw. Gießlinie 1 zuletzt mit der Ausbringung ihres Gußstranges 21 begonnen hat, wird also die Fähre 16 aus ihrer Grundstellung nach Fig. 1 in Querrichtung verfahren, bis sie in Fluchtlage mit dem Rollenherdofen 14 und dem Aufnahmeofen 18 gelangt, wie das in Fig. 2 der Zeichnung zu sehen ist. Die erste Dünnbramme 25 wird dann unmittelbar in Längsrichtung über die Fähre 16 in den Aufnahmeofen 18 transportiert und kann anschließend aus diesem in die Warmbreitband-Fertigstraße 19 eingezogen werden. Gleichzeitig mit dem Abschieben der Dünnbramme 25 von der Fähre 16 in den Aufnahmeofen 18 wird eine Dünnbramme 26 aus dem Pufferbereich 12 des Rollenherdofens 15 auf die in ihrer Grundstellung verbliebene Fähre 17 verbracht, wie dies aus Fig. 2 der Zeichnung ersichtlich ist.Since the casting machine or casting line 1 has last started with the delivery of its cast strand 21, the ferry 16 is thus moved from its basic position according to FIG. 1 in the transverse direction until it comes into alignment with the roller hearth furnace 14 and the receiving furnace 18, as in FIG Fig. 2 of the drawing can be seen. The first thin slab 25 is then transported directly in the longitudinal direction via the ferry 16 into the receiving furnace 18 and can then be drawn into the hot strip mill 19 from this. Simultaneously with the removal of the thin slab 25 from the ferry 16 into the receiving furnace 18, a thin slab 26 is moved from the buffer area 12 of the roller hearth furnace 15 onto the ferry 17 which remains in its basic position, as can be seen from FIG. 2 of the drawing.

Nunmehr werden die beiden Fähren 16 und 17 gemeinsam bzw. synchron aus ihrer der Fig. 2 entsprechenden Betriebsstellung in die Betriebsstellung nach Fig. 3 gebracht. Dadurch gelangt die Fähre 16 aus ihrer Fluchtlage mit dem Rollenherdofen 14 in Fluchtlage mit dem Rollenherdofen 13, während die Fähre 17 aus der Fluchtlage mit dem Rollenherdofen 15 in Fluchtlage mit dem nachgeordneten Aufnahmeofen 18 gelagt. Während dann von der Fähre 17 die darauf ruhende Dünnbramme 26 in den Aufnahmeofen 18 transportiert wird, gelangt gleichzeitig die Dünnbramme 24 aus dem Pufferbereich 10 des Rollenherdofens 13 auf die Fähre 16.Now the two ferries 16 and 17 are brought together or synchronously from their operating position corresponding to FIG. 2 into the operating position according to FIG. 3. As a result, the ferry 16 arrives from its flight position with the roller hearth furnace 14 in the flight position with the roller hearth furnace 13, while the ferry 17 lies in the flight position with the roller hearth furnace 15 in the flight position with the downstream receiving furnace 18. Then, while the thin slab 26 resting thereon is transported by the ferry 17 into the receiving furnace 18, the thin slab 24 simultaneously arrives at the ferry 16 from the buffer area 10 of the roller hearth furnace 13.

Anschließend werden die beiden Fähren 16 und 17 wiederum gemeinsam bzw. synchron in entgegengesetzter Richtung quer verfahren, so daß die Fähre 17 unbeladen in Fluchtlage zum Rollenherdofen 15 zurückkehrt, während die mit der Dünnbramme 24 beladene Fähre 16 in Fluchtlage mit dem Aufnahmeofen 18 gelangt, um die Dünnbramme 24 in diesen einzufahren, während zugleich die Fähre 16 mit der nächsten Dünnbramme 25 beladen wird. Fähre 17 bleibt unbeladen. Beide Fähren 16 und 17 verbleiben über die Länge eines Walzzyklus in ihrer Lage. Danach wird die Dünnbramme 25 in den Aufnahmeofen 18 und die Dünnbramme 26 in die Fähre 17 eingefahren.Then the two ferries 16 and 17 are again transversely moved together or synchronously in the opposite direction, so that the ferry 17 unloaded in the flight position Roller hearth furnace 15 returns, while the ferry 16 loaded with the thin slab 24 comes into alignment with the receiving furnace 18 in order to move the thin slab 24 into it, while at the same time the ferry 16 is loaded with the next thin slab 25. Ferry 17 remains unloaded. Both ferries 16 and 17 remain in position for the length of a rolling cycle. The thin slab 25 is then moved into the receiving furnace 18 and the thin slab 26 into the ferry 17.

Nachdem die Fähre 17 mit der Dünnbramme 26 beladen ist, werden wiederum beide Fähren 16 und 17 synchron bzw. gemeinsam in die der Fig. 3 entsprechende Stellung verfahren.After the ferry 17 is loaded with the thin slab 26, both ferries 16 and 17 are again moved synchronously or together into the position corresponding to FIG. 3.

Beim Betrieb der Gesamtanlage ist es dabei wichtig, daß die Ladezeit für die Dünnbrammen 24, 25, 26 aus den Pufferzonen 10, 11, 12 der Rollenherdöfen 13, 14, 15 der Entladezeit entspricht, welche für das Überführen der einzelnen Dünnbrammen 24, 25, 26 von den Fähren 16 bzw. 17 in den Aufnahmeofen 18 erforderlich ist.When operating the entire system, it is important that the loading time for the thin slabs 24, 25, 26 from the buffer zones 10, 11, 12 of the roller hearth furnaces 13, 14, 15 corresponds to the unloading time which is required for the transfer of the individual thin slabs 24, 25, 26 of the ferries 16 and 17 in the receiving furnace 18 is required.

Ebenso wichtig ist aber auch, die Geschwindigkeit so zu bemessen, daß die Walzzeit für jede Dünnbramme 24, 25, 26 in der Warmbreitband-Fertigstraße 19 immer den Zeitraum überschreitet, welcher gemeinsam für die Ladezeit bzw. Entladezeit der Fähren 16 bzw. 17 und deren Fahrzeit zum Quertransport der Dünnbrammen 24, 25, 26 benötigt wird.However, it is equally important to measure the speed so that the rolling time for each thin slab 24, 25, 26 in the hot strip mill 19 always exceeds the time period which is common for the loading or unloading time of the ferries 16 and 17 and their Travel time for the transverse transport of the thin slabs 24, 25, 26 is required.

Ebenso wie die stationären Rollenherdöfen 13, 14, 15 und der stationäre Aufnahmeofen 18 sind auch die beiden jeweils als Längs/Quer/Längs-Transportsysteme betreibbaren Fähren 16 und 17 beheizbar ausgeführt. Vorzugsweise lassen sie sich dabei als in Querrichtung verfahrbare Rollenherdöfen ausführen, damit deren Herdrollen zum zwangsweisen Längstransport der einzelnen Dünnbrammen 24, 25, 26 genutzt werden können.Just like the stationary roller hearth furnaces 13, 14, 15 and the stationary receiving furnace 18, the two ferries 16 and 17, which can each be operated as longitudinal / transverse / longitudinal transport systems, are also heatable. They can preferably be designed as roller hearth furnaces which can be moved in the transverse direction, so that their hearth rollers can be used for the forced longitudinal transport of the individual thin slabs 24, 25, 26.

Abweichend von dem vorstehend anhand der Fig. 1 bis 4 erläuterten Funktionsablauf können die beiden Fähren 16 und 17 situationsbedingt entweder ihre Position beibehalten oder aber zu einer jeweils komplementären Strangkombination verfahren. Entscheidend ist hierfür immer der Umstand, aus welchem der hergestellten Gußstränge 21, 22, 23 frühestens eine übernahmebereite Dünnbramme 24, 25, 26 erwartet werden kann. Alle Gußstränge 21, 22, 23 können von der Kombination der beiden Fähren 16 und 17 gleichwertig behandelt werden.In a departure from the functional sequence explained above with reference to FIGS. 1 to 4, depending on the situation, the two ferries 16 and 17 can either maintain their position or move to a complementary strand combination. The decisive factor here is always the circumstance from which the cast strands 21, 22, 23 produced can at the earliest be expected to receive a thin slab 24, 25, 26 ready for takeover. All cast strands 21, 22, 23 can be treated equally by the combination of the two ferries 16 and 17.

Die Folgezeiten der Dünnbrammen 24, 25, 26 können - abhängig von der jeweiligen Einzugsgeschwindigkeit der Warmbreitband-Fertigstraße 19 - entweder vergleichmäßigt oder aber zur Erzielung von Pufferzeiten für die Durchführung von Walzenwechseloperationen gezielt und symmetrisch gefahren werden. Hierzu müssen natürlich sämtliche Längstransporte, welche zwischen den Gießmaschinen bzw. Gießlinien 1, 2, 3 und der Warmbreitband-Fertigstraße 19 betrieben werden, hinsichtlich ihrer Transportgeschwindigkeit in Grenzen regelbar sein, die einerseits durch die Gießgeschwindigkeit der einzelnen Gußstränge 21, 22, 23 und andererseits durch die Einzugsgeschwindigkeit der Warmbreitband-Fertigstraße 19 betimmt sind.The subsequent times of the thin slabs 24, 25, 26 can - depending on the respective drawing-in speed of the hot broadband finishing train 19 - either be made more uniform or, in order to achieve buffer times for the execution of roll changing operations, can be carried out in a targeted and symmetrical manner. For this purpose, of course, all longitudinal transports that are operated between the casting machines or casting lines 1, 2, 3 and the hot-rolled strip finishing line 19 must be controllable in terms of their transport speed, on the one hand by the casting speed of the individual casting strands 21, 22, 23 and on the other hand are determined by the retraction speed of the hot strip mill 19.
