Description

Die Erfindung bezieht sich auf eine Bandgießmaschine zur Erzeugung eines Metallbandes, mit zwei nebeneinander angeordneten, einen Gießspalt bildenden Gießrollen, welche auf einem Rahmengestellt drehbar gelagert sind, wobei das die Gießrollen tragende Rahmengestell auf Schienen von der Gießposition in eine Wartungsposition und umgekehrt verschiebbar ist, dass beidseitig zur Giessposition Schienen weglaufend angeordnet sind.The invention relates to a strip casting machine for producing a metal strip, with two juxtaposed, a casting gap forming casting rolls which are rotatably mounted on a Rahmengestellt, wherein the casting rolls supporting frame on rails from the casting position into a maintenance position and vice versa is displaceable Both sides of the casting position rails are arranged running away.

Bei Bandgießmaschinen mit zwei im Wesentlichen parallel angeordneten Gießrollen begrenzen Schmalseiten den Gießspalt. Beim Gießen von Bändern, insbesondere von Stahlbändem, werden die Schmalseiten sowohl durch die Reibung an den Gießrollen als auch im unteren Teil durch die Reibung des erstarrten Bandes durch abrasiven Verschleiß und müssen in einer Gießpause ersetzt werden. Beim Auswechseln werden die Schmalseiten aus der Gießposition, in welche die Schmalseiten and en Ballen anliegen, im Wesentlichen waagerecht mittels der Anstellreinrichtung von den Ballen weg in eine Anstellposition bewegt und anschließend mittels Schmalseitenwechselvorrichtung z. B. Robotern, die auf jeder Maschinenseite auf der Gießbühne angeordnet sind, nach oben aus der Anstellposition entfernt. Die japanische Offenlegungsschrift JP-5-32 95 83 A beschreibt beispielsweise einen solchen Roboter für das Auswechseln der Schmalseiten.In strip casting machines with two casting rolls arranged substantially parallel, narrow sides define the casting gap. When casting tapes, especially Stahlbändem, the narrow sides by both the friction of the casting rolls and in the lower part by the friction of the solidified band by abrasive wear and must be replaced in a casting break. When replacing the narrow sides of the casting position, in which rest the narrow sides and en ball, moved substantially horizontally by means of Anstellreinrichtung away from the bale in a set position and then by means of narrow side change device z. B. robots, which are arranged on each side of the machine on the casting platform, removed upwards from the setting position. The Japanese Laid-Open Patent Publication No. 5-329583A describes, for example, such a robot for the replacement of the narrow sides.

Bei bekannten Bandgießmaschinen sind die Gießrollen stationär und fest unterhalb eines Drehturmes und eines Verteilergefäßes oder dergleichen angeordnet. Wenn nun diese Gießrollen beispielsweise durch Nachschleifen revidiert oder ausgewechselt werden müssen, so ist dies mit aufwendigen Demontage- bzw. Montagearbeiten verbunden, das diese Gießrollen an sich schlecht zugänglich sind und aufgrund ihres Gewichtes mit einem Kran weggetragen bzw. millimeter genau wieder eingesetzt werden müssen. Auch die An- bzw. Abkoppelung der Wasseranschlüsse oder der elektrischen Verbindungsleitungen ist aufgrund der vorhandenen Zugänglichkeit mit umständlichen Arbeitsvorgängen verbunden, bei denen sogar das die Gießrollen lagemde Rahmengestell geteilt werden muss.In known continuous casting machines, the casting rolls are stationary and fixed beneath a turret and a tundish or the like. Now, if these casting rolls have to be revised or replaced, for example, by regrinding, this is associated with costly disassembly or assembly work, these casting rolls are difficult to access and carried away because of their weight with a crane or millimeter must be used exactly again. The arrival or decoupling of the water connections or the electrical connection lines is due to the available accessibility associated with cumbersome operations in which even the casting rolls lagemde framework must be shared.

Ein weiterer Nachteil bei diesen bekannten Bandgießmaschinen besteht darin, dass während den Instandstellungs- bzw. Wartungsarbeiten der Gießrollen und der Maschine nicht gegossen werden kann und damit die Gießleistung der Anlage beschränkt ist.Another disadvantage with these known strip casting machines is that during the maintenance or servicing of the casting rolls and the machine can not be poured and thus the casting capacity of the system is limited.

Bei einer gattungsgemäßen Bandgießmaschine nach der Druckschrift WO-A-93/22087 sind die Gießrollen auf einem Wagen gelagert, der seinerseits auf Schienen um eine annähernd halbe Wagenlänge mittels eines Zylinders verschiebbar ist. Diese Ausführung der Bandgießmaschine eignet sich jedoch nur für kleinere Gießrollen-Durchmesser. Auch in der von der Gießposition weg geschobenen Wartungsstellung ist die Zugänglichkeit der Gießrollen nur beschränkt besser, da sich diese nahe bei der Gießstellung befindet.In a generic strip casting machine according to the document WO-A-93/22087 the casting rolls are mounted on a carriage, which in turn is displaceable on rails by an approximately half the length of the carriage by means of a cylinder. However, this embodiment of the strip casting machine is only suitable for smaller casting rolls diameter. Also in the pushed away from the casting position maintenance position, the accessibility of the casting rolls is only limited better because it is close to the casting position.

In dem Dokument US-A-5,184,668 ist eine Bandgießmaschine mit zwei Gießrollen dargestellt. Die Gießrollen sind mit Seitenabdichtungen versehen und auf einem Wagen montiert. In der Gießposition wird aus einem Verteiler flüssiges Metall in den Raum zwischen den Gießrollen gegossen. Aus dem Gießspalt zwischen den Gießrollen wird das erstarrte Metallband seitlich nach unten abgezogen und zu einem Metallbund aufgewickelt. In einer Aufheizposition, die sich eine halbe Wagenlänge seitlich zur Gießposition befindet, werden die Seitenabdichtungen und das Gießrohr in Öfen aufgeheizt und mit den Gießrollen verbunden. Anschließend wird der Wagen unverzüglich von der Aufheizstation in die Gießstation gefahren, in der das Bandgießen durchgeführt wird.In the document US-A-5,184,668 a ribbon casting machine is shown with two casting rolls. The casting rolls are provided with side seals and mounted on a trolley. In the casting position, liquid metal is poured from a distributor into the space between the casting rolls. From the casting gap between the casting rolls the solidified metal strip is pulled off laterally down and wound into a metal collar. In a heating position, which is half a carriage length to the side of the casting position, the side seals and the pouring tube are heated in ovens and connected to the casting rolls. Subsequently, the car is driven immediately by the heating station in the casting station, in which the strip casting is performed.

Der vorliegenden Erfindung wurde demgegenüber die Aufgabe zugrunde gelegt, eine Bandgießmaschine nach der eingangs erwähnten Gattung zu schaffen, bei der eine optimale Zugänglichkeit zu der Maschine und insbesondere auch zu den Gießrollen ermöglicht ist, mittels der eine schnelle Wartung bzw. ein Wechsel derselben erfolgen kann, und bei der die Verfügbarkeit der Bandgießmaschine für das Vergießen und damit die Gießleistung derselben erhöht werden kann.The present invention was the object of the present invention to provide a strip casting machine according to the type mentioned, in which an optimal accessibility to the machine and in particular to the casting rolls is made possible by means of a quick maintenance or a change of the same can take place, and in which the availability of the strip casting machine for the casting and thus the casting performance of the same can be increased.

Die Aufgabe ist erfindungsgemäß nach den Merkmalen des Anspruches 1 gelöst.The object is achieved according to the features of claim 1.

Mit dieser erfindungsgemäßen Ausführung der Bandgießmaschine, bei der die Gießrollen in eine von der Gießposition entfemte Wartungsposition verschiebbar sind und sofort durch andere vorbereitete Gießrollen ersetzt werden können, ergeben sich erhebliche Vorteile gegenüber den bekannten Systemen. Das gilt insbesondere dann, wenn die Gießrollen auf einem Rahmengestell drehbar gelagert sind und das Rahmengestell, mit dem Gehäuse um die genannte Distanz von der Gießposition weg verschiebbar sind und ein zweites mit vorbereiteten Gießrollen versehenes Gehäuse in die Gießposition verschiebbar ist.With this embodiment of the strip casting machine according to the invention, in which the casting rolls are displaceable into a maintenance position remote from the casting position and can be replaced immediately by other prepared casting rolls, there are considerable advantages over the known systems. This is especially true when the casting rolls are rotatably mounted on a frame and the frame, with the housing by said distance from the casting position are displaced away and a second provided with prepared casting rolls housing is displaceable in the casting position.

Durch das Verschieben des Rahmengestells mit den Gießrollen und zusammen mit dem Gehäuse zu einem Wartungsplatz können bei diesen Werkzeuge, Lehren, Nachbearbeitungsgeräte, Mess- und andere Kontrollgeräte stationär eingerichtet werden.By moving the frame with the casting rolls and together with the housing to a maintenance place, these tools, gauges, finishing devices, measuring and other control devices can be set stationary.

Dies erlaubt ein schnelles und außerdem professionelles Warten und Wiederinstandstellen der Maschine. Nach dem Wegfahren eines Rahmengestelles mit dem Gehäuse zum Beispiel beim Wechsel der Gießrollen mit anderen Breiten oder bei nicht mehr funktionstüchtigen Gießrollen, können sofort vorbereitete Gießrollen auf einem anderen Rahmengestell mit dem Gehäuse unterhalb des Verteilergefäßes gebracht werden und es kann hierdurch ein Metallband angegossen oder weiter gegossen werden.This allows a fast and also professional maintenance and repair of the machine. After driving away a frame with the housing, for example, when changing the casting rolls with other widths or if the casting rolls are no longer functional, immediately prepared casting rolls can be placed on another frame with the housing underneath the distribution vessel, and a metal strip can then be cast or poured on.

Fig.1 zeigt eine Bandgiessmaschine 20 einer Giessanlage 10 eines in einem kontinuierlichen Giessverfahren erzeugbaren Metallbandes 15, insbesondere eines Stahlbandes. Diese Bandgiessmaschine 20 steht auf einem Trägersystem 12 und wird von einem über ihr stehenden, nicht gezeigten Verteilergefäss mit Metallschmelze versorgt, wie dies bei an sich herkömmlichen Stranggiessanlagen bekannt ist. Fig.1 shows a strip casting machine 20 of a casting plant 10 of a producible in a continuous casting metal strip 15, in particular a steel strip. This strip casting machine 20 stands on a carrier system 12 and is supplied with molten metal from a distributor vessel, not shown above it, as is known in conventional continuous casting plants.

Zur Hauptsache hat diese Bandgiessmaschine 20 zwei im wesentlichen parallel nebeneinander angeordnete Giessrollen 22, 24 mit annähernd horizontalem Drehachsenverlauf, die an beiden Stirnseiten mit je einer Seitenabdichtung 25 versehen sind, wodurch eine rundum geschlossene Öffnung mit einem nach unten hin offenen Giessspalt gebildet ist. Die Giessrollen 22, 24 sind beidseits auf je einem Rahmengestell 32 drehbar gelagert und von je einem Motor gesteuert angetrieben. Das Rahmengesteil 32, 32' kann zum Zwecke einer Einstellung der Breite des Giessspaltes mit seinem einen Teil 32' und der diesem zugehörigen Giessrolle 22 durch ein Verstellmittel 72 um eine Achse 71 geschwenkt werden.For the main thing, this strip casting machine 20 has two substantially parallel juxtaposed casting rolls 22, 24 with approximately horizontal axis of rotation, which are provided on both end faces, each with a side seal 25, whereby an all-round closed opening is formed with a downwardly open casting gap. The casting rollers 22, 24 are rotatably mounted on both sides on a frame frame 32 and driven by a motor driven each. For the purpose of adjusting the width of the casting gap, its frame part 32, 32 'can be swiveled about an axis 71 with its one part 32' and the associated casting roll 22 by an adjusting means 72.

Die Giessrollen 22, 24 sind je aus einem motorisch angetriebenen zylindrischen Mantel und aus einer diesen drehbar lagernden feststehenden Achse 75 gebildet, wobei die jeweilige Achse 75 mit ihren beidseitigen Enden auf dem Rahmengestell 32, 32' getragen ist. Diese Ausführung mit den feststehenden Achsen 75 ermöglicht eine einfache Bauweise derselben zusammen mit dem Rahmengestell.The casting rolls 22, 24 are each formed of a motor-driven cylindrical shell and a rotatably supporting these fixed axis 75, wherein the respective axis 75 is supported with its two ends on the frame 32, 32 '. This embodiment with the fixed axles 75 allows a simple construction thereof together with the frame.

Die Giessrollen 22, 24 mit dem Rahmengestell 32 und den Seitenabdichtungen 25 sind rundum von einem verschliessbaren Gehäuse 30 umgeben, wobei das Gehäuseinnere 33 während des Giessens mit einem Schutzgas, vorzugsweise einem Inertgas, gefüllt ist. Dieses kastenförmig ausgebildete Gehäuse 30 ist sehr vorteilhaft sowohl seitlich als auch oben beabstandet zu den Giessrollen 22, 24 bzw. zum Maschinenständer 32 angeordnet.The casting rolls 22, 24 with the frame 32 and the side seals 25 are surrounded all around by a closable housing 30, wherein the housing interior 33 is filled during the casting with a protective gas, preferably an inert gas. This box-shaped housing 30 is arranged very advantageously both laterally and at a distance from the casting rolls 22, 24 or to the machine stand 32.

Auf der Oberseite dieses Gehäuse 30 ist ein in etwa horizontal auf diesem liegender Deckel 35 vorgesehen, welcher von der gezeigten geschlossenen in eine angehobene Position 35' und von dieser in eine horizontal weggeschobene Position 35" verschiebbar ist. Zu diesem Zwekke hat er seitlich Rollen 27, die auf entsprechenden Schienen 28 geführt sind. In der gezeigten Schliessposition ist der Deckel 35 mit Vorteil auf das Niveau des Bodens 14 abgesenkt, um die bezweckte Dichtheit des Gehäuses 30 zu erreichen.On the upper side of this housing 30 there is provided a cover 35 which lies approximately horizontally on the latter and which can be displaced from the closed position shown into a raised position 35 'and from this into a horizontally pushed-away position 35 " , which are guided on corresponding rails 28. In the shown closed position, the cover 35 is advantageously lowered to the level of the bottom 14 in order to achieve the intended tightness of the housing 30.

Des weiteren sind dem Gehäuse 30 seitlich ebenfalls mittels Türen 36 verschliessbare Öffnungen 39 zugeordnet, welche dazu dienen, dass die Seitenabdichtungen 25 der Giessrollen 22, 24 von jeweils einem ausserhalb des Gehäuses 30 verfahrbaren Manipulator 40 von der gezeigten Betriebsposition durch diese Öffnungen 39 aus dem bzw. in das Gehäuse 30 geführt werden können. Der jeweilige Manipulator 40 hat zu diesem Zwecke einen Haltearm 41, an dem die Seitenabdichtung 25 befestigt ist, die durch diesen Manipulator 40 von einer Betriebs- in eine zurückgezogene Wartungsposition 25' und umgekehrt verfahren werden kann. In der Betriebsposition des Manipulators 40 kann mittels einer separaten Schutzhülle 38 eine Abdichtung der nicht geschlossenen Öffnung 39 herbeigeführt werden. Diese Schutzhülle 38 umschliesst den Manipulator 40 und ist demnach seitlich an das Gehäuse 30 dicht angedrückt. Ferner sind noch Kassetten 88 für das Heranführen und Wegnehmen von Seitenabdichtungen 25 angedeutet. Mit Vorteil sind beidseitig zum Gehäuse 30 je zwei solcher Manipulatoren 40 installiert, die wechselweise bei den Stirnseiten der Giessrollen 22, 24 die entsprechenden Seitenabdichtungen 25 heranführen und letztere während des Giessens in einer genau positionierten Lage an die Giessrollen andrükken.Furthermore, the housing 30 are also laterally sealed by means of doors 36 closable openings 39, which serve that the Seitenabdichtungen 25 of the casting rolls 22, 24 of each one outside the housing 30 movable manipulator 40 from the operating position shown by these openings 39 from the or . Can be guided in the housing 30. The respective manipulator 40 has for this purpose a holding arm 41, on which the side seal 25 is fixed, which can be moved by this manipulator 40 from an operating to a retracted maintenance position 25 'and vice versa. In the operating position of the manipulator 40, a seal of the non-closed opening 39 can be brought about by means of a separate protective sheath 38. This protective cover 38 encloses the manipulator 40 and is therefore pressed against the side of the housing 30. Furthermore, cassettes 88 for the introduction and removal of side seals 25 are indicated. Advantageously, two such manipulators 40 are installed on both sides of the housing 30, which alternately introduce the corresponding side seals 25 at the end faces of the casting rolls 22, 24 and the latter press on the casting rolls during casting in a precisely positioned position.

Unterhalb des Gehäuses 30 ist das gegossene Metallband 15 in einem zusätzlichen Längsgehäuse 44 geführt, das eine Kammer 45 bildet, in der ebenfalls ein Schutzgas enthalten ist, um das Metallband 15 vor einem Kontakt mit Sauerstoff und damit insbesondere vor einer Zunderbildung zu schützen. In dieser Kammer 45 sind mehrere Rollen 46 und Presswalzen 47 angeordnet, so dass das Metallband 15 durch dieses Längsgehäuse 44 und durch eine in ihm endseitig abgedichtete Öffnung 58 geführt wird. Nach dem Austritt aus diesem Gehäuse 44 kann dieses Metallband beispielsweise gewalzt, gekühlt, aufgerollt oder anderweitig bearbeitet werden.Below the housing 30, the cast metal strip 15 is guided in an additional longitudinal housing 44, which forms a chamber 45, in which also a protective gas is contained in order to protect the metal strip 15 from contact with oxygen and thus in particular from scale formation. In this chamber 45 a plurality of rollers 46 and press rollers 47 are arranged so that the metal strip 15 is guided through this longitudinal housing 44 and through an end 58 sealed in it opening. After exiting this housing 44, this metal strip can for example be rolled, cooled, rolled up or otherwise processed.

Ferner weist das Längsgehäuse 44 unterhalb der Öffnung 30" bzw. des Giessspaltes eine Vertiefung 49 auf, bei der ein in einem Anlagenboden 61 hinein gestellter Auffangbehälter 52 vorhanden ist. Dieser Auffangbehälter 52 hat die Aufgabe, bei einer Leckage die unten aus den Giessrollen austretende flüssige Schmelze aufzufangen, ohne dass irgendwelcher Schaden entstehen würde. Oberhalb dieses Behälters 52 sind noch verschwenkbare Führungsklappen 54, 55 angeordnet, die in der dargestellten Position einen Durchlass bilden, indessen in der strichpunktierten Schwenkposition 54', 55' als Führungsbahn des Metallbandes 15 dienen.Furthermore, the longitudinal housing 44 below the opening 30 "or of the casting gap has a depression 49, in which there is a collecting container 52 placed in a plant bottom 61. This collecting container 52 has the function of discharging the liquid emerging from the casting rolls in the event of leakage melt to catch without causing any damage. Above this container 52 still pivotable guide flaps 54, 55 are arranged, which form a passage in the position shown, meanwhile serve in the dash-dotted pivot position 54 ', 55' as a guide track of the metal strip 15.

Das Gehäuse 30 weist eine nicht näher gezeigte Zuleitung für das Einblasen von Schutzgas in sein Inneres 33 auf, welches durch einen GasKreislauf gekühlt und zurückgeführt werden kann. Nach Beendigung eines Giessvorganges und vor dem Öffnen des Gehäuses kann das Schutzgas in einen Speicher abgesogen und gegebenenfalls die Luft in diesem herausgefiltert werden.The housing 30 has a supply line not shown in detail for the injection of inert gas into its interior 33, which can be cooled by a gas circulation and recycled. After completion of a casting process and before the opening of the housing, the inert gas can be sucked into a memory and optionally the air is filtered out in this.

Erfindungsgemäss sind die Giessrollen 22, 24 und wenigstens das diese tragende Rahmengestell 32 und das Gehäuse 30 auf Schienen 48 oder dergleichen von der gezeigten Giessposition G in eine Wartungsposition W und umgekehrt verschiebbar angeordnet. Im vorliegenden Ausführungsbeispiel ist auch das dieses Rahmengestell 32 umschliessende kastenförmige Gehäuse 30 verfahrbar, wobei es zu diesem Zwecke aussen auf den Schienen 48, 48' geführte Räder 37 hat.According to the invention, the casting rolls 22, 24 and at least the frame frame 32 carrying them and the housing 30 are displaceably arranged on rails 48 or the like from the pouring position G shown in a maintenance position W and vice versa. In the present embodiment, this frame frame 32 enclosing box-shaped housing 30 is movable, and it has for this purpose outside on the rails 48, 48 'guided wheels 37.

Die das Gehäuse 30 tragenden, als Paare ausgebildete Schienen 48, 48' sind - wie dies auch in Fig.2 ersichtlich ist - im Bereich der Giessposition G von der übrigen Länge getrennt und von auf einer Struktur 62 befestigten Hubzylindern 51 oder dergleichen in der Höhe verstellbar angeordnet. In Fig.1 sind sie zusammen mit dem Gehäuse 30 in der abgesenkten, indessen in Fig.2 in der mit den angrenzenden Schienen 48' bundigen Position dargestellt. In der abgesenkten Position ist beim Gehäuseboden eine Verbindung der zu den Giessrollen 22, 24 führenden Wasserzufuhrleitungen 64 mit der Wasserversorgung 65 vorgesehen, wobei die Wasserzufuhrleitungen 64 im Rahmengestell 32 enthalten sind und die Wasserversorgung 65 mit entsprechenden Zu- und Ableitungen unterhalb des Gehäuses 30 angeordnet ist. Hiermit ergibt sich eine automatische Verbindung bzw. Trennung dieser Leitungen 64 bei Betätigung der Hubzylinder 51. Mittels nicht näher gezeigten Rückschlagventilen kann bei einem Trennen ein Auslaufen des Kühlwassers verhindert werden.The housing 30 carrying, designed as pairs rails 48, 48 'are - as in Fig.2 it can be seen - in the casting position G separated from the remaining length and arranged adjustable in height by mounted on a structure 62 lifting cylinders 51 or the like. In Fig.1 they are together with the housing 30 in the lowered, meanwhile in Fig.2 shown in the flush with the adjacent rails 48 'position. In the lowered position, a connection of the leading to the casting rolls 22, 24 water supply lines 64 is provided with the water supply 65 at the bottom of the housing, the water supply lines 64 are included in the frame 32 and the water supply 65 is arranged with corresponding supply and discharge lines below the housing 30 , This results in an automatic connection or disconnection of these lines 64 upon actuation of the lifting cylinder 51. By means of non-descript check valves can be prevented in a separation leakage of the cooling water.

Der Deckel 35 liegt mit seiner unteren Auflagefläche in der abgesenkten, das Gehäuse schliessenden Position unterhalb des Bodens 14, damit das Gehäuse 30 unterhalb des Bodens 14 horizontal verschiebbar ist. Der Deckel ist gemäss Fig.2, wenn er verfahren wird, mit seinen Rollen 27 auf den Schienen 28 getragen und kann von Hubzylindern 74 unabhängig vom Gehäuse angehoben bzw. abgesenkt werden kann.The cover 35 lies with its lower support surface in the lowered, the housing closing position below the bottom 14, so that the housing 30 is horizontally displaceable below the bottom 14. The lid is according to Fig.2 when it is moved, carried with its rollers 27 on the rails 28 and can be raised or lowered by lifting cylinders 74 regardless of the housing.

Bei einem Wechsel des Gehäuses 30 wird ein neues mit vorbereiteten Giessrollen 30 in Giessposition G verschoben und abgesenkt. Sodann werden die Seitenabdichtungen 25 mittels den Manipulatoren 40 an die Stirnseiten der Giessrollen 22, 24 mit einem definierten Druck angepresst, die Schutzhüllen 38 und der Deckel 35 dicht an das Gehäuse 30 angeschlossen und letzteres in seinem Innern durch das Schutzgas inertisiert.When changing the housing 30, a new with prepared casting rollers 30 is moved in casting position G and lowered. Then, the side seals 25 are pressed by means of the manipulators 40 to the end faces of the casting rolls 22, 24 with a defined pressure, the protective sheaths 38 and the lid 35 is tightly connected to the housing 30 and the latter inertized in its interior by the inert gas.

Dieser Wechsel der Giessrollen 22, 24 kann als weiterer Vorteil der Erfindung sogenannt fliegend ausgeführt werden, d.h. dass das durch den Deckel 35 zwischen die Giessrollen 22, 24 ragende Giessrohr ohne Anheben des dieses haltenden Verteilergefässes 18 positioniert gehalten werden kann. Der Deckel 35 wird beim Wechsel angehoben und die Giessrollen 22, 24 werden nach dem Wegnehmen der Seitenabdichtungen 25 vom Gehäuse 30 entlang ihrer Drehachsen horizontal weggefahren und entsprechend werden die neuen, bspw. mit anderen Breiten versehene Giessrollen derart zugeführt, dass das Giessrohr berührungslos zwischen diesen wieder zu stehen kommt. Dadurch kann weitergegossen werden, ohne dass das Verteilergefäss 18 geleert werden müsste. Beim Wiederangiessen muss nur das Schliessorgan beim Auslass desselben geöffnet werden. Damit lässt sich eine erhebliche Leistungssteigerung mit dieser erfindungsgemässen Bandgiessmaschine erzielen.This change of the casting rolls 22, 24 can be carried out as a further advantage of the invention so-called flying, i. that the pouring tube projecting through the lid 35 between the casting rolls 22, 24 can be kept positioned without lifting the distributor vessel 18 holding this. The lid 35 is raised when changing and the casting rolls 22, 24 are moved away horizontally after removing the side seals 25 from the housing 30 along their axes of rotation and accordingly, the new, for example, provided with other widths casting rolls supplied such that the pouring tube without contact between them comes to stand again. This allows further pouring without the distributor vessel 18 having to be emptied. When re-casting only the closing organ at the outlet of the same must be opened. This makes it possible to achieve a considerable increase in performance with this strip casting machine according to the invention.

Gemäss Fig.3 ist im Rahmen der Erfindung das Gehäuse 30 mit den in diesem enthaltenen gebrauchten Giessrollen 22, 24 um eine solche Distanz von der Giessposition G weg verschiebbar angeordnet, dass ein zweites Gehäuse 30' mit vorbereiteten Giessrollen in die Giessposition G verfahrbar ist. Nach Erreichen der Giessposition G kann dieses Gehäuse 30' durch Absenken der Schienen 48, der Verbindung der Leitungen 64 mit der Wasserversorgung 65 und dem Schliessen durch den Deckel 35 in Giessbereitschaft gestellt werden. Mit Vorteil beträgt die Distanz zwischen der Giessposition G und der Wartungsposition W einige Gehäuse längen, damit in der Wartungsposition ungestört von dem Giessablauf gearbeitet werden kann. Dies richtet sich nach den Gegebenheiten einer einzelnen Giessanlage.According to Figure 3 is within the scope of the invention, the housing 30 with the used therein casting rolls 22, 24 displaceably arranged by such a distance from the casting position G, that a second housing 30 'with prepared casting rolls in the casting position G is movable. After reaching the Giessposition G, this housing 30 'can be made by lowering the rails 48, the connection of the lines 64 to the water supply 65 and the closing by the lid 35 in readiness for casting. Advantageously, the distance between the Giessposition G and the maintenance position W some housing lengths, so that you can work undisturbed in the maintenance position of the pouring. This depends on the circumstances of a single casting plant.

Fig.4 zeigt diese Giessanlage 10, die mit einem Strang arbeitet. Ein an sich herkömmlicher Drehturm 81 hält eine Pfanne 82, von welcher die Stahlschmelze in ein Verteilergefäss 18 und von diesem zwischen die in Giessposition G befindlichen Giessrollen abgegossen wird. Das unten zwischen diesen Giessrollen austretende Metallband wird dann in der Pfeilrichtung 83 weggeleitet. In der Wartungsposition W werden die Giessrollen 22, 24 gewartet, beispielsweise durch Abdrehen bzw. Abschleifen oder andere Oberflächenbehandlungen, oder gegebenenfalls durch angedeutete neue Giessrollen ersetzt. Diese Giessrollen 22, 24 sind zusammen mit einem Gehäuse 30 auf den Schienen 48' weggeschoben worden. Auch Verteilergefässe 18, 18' sind für einen Einsatz bereitgestellt. Diese könnten auch von dem Drehturm in Giessposition geschwenkt werden. Figure 4 shows this casting plant 10, which works with a strand. A conventional turret 81 holds a ladle 82, from which the molten steel is poured into a distributor vessel 18 and from there between the casting rolls located in the casting position G. The metal strip emerging below between these casting rolls is then directed away in the direction of arrow 83. In the maintenance position W, the casting rolls 22, 24 are maintained, for example, by twisting or grinding or other surface treatments, or possibly replaced by indicated new casting rolls. These casting rolls 22, 24 have been pushed together with a housing 30 on the rails 48 '. Also, distribution vessels 18, 18 'are provided for use. These could also be pivoted by the turret in Giessposition.

Fig.5 zeigt eine Giessanlage 80 mit zwei nebenemander befindlichen Strängen, bei der im Unterschied zu derjenigen nach Fig.4 entsprechend zwei Drehtürme 81 und je eine Wartungspositionen W vorgesehen sind. Ausserdem sind zwischen den Giesspositionen G der beiden Stränge zwei Gehäuse 30 mit Giessrollen 22, 24 stationiert, die vorteilhaft ebenfalls als Wartungsposition dient. Figure 5 shows a casting plant 80 with two adjacent strands, in contrast to that after Figure 4 correspondingly two revolving towers 81 and one maintenance positions W each are. In addition, two housings 30 with casting rolls 22, 24 are stationed between the casting positions G of the two strands, which likewise advantageously serves as a maintenance position.

Die Seitenabdichtungen könnten im Prinzip anstatt von einem Manipulator 40 seitlich der Giessrollen positioniert zu werden, auch auf dem Rahmengestell angeordnet sein und mit diesem und dem Gehäuse 30 in die Wartungsposition weggebracht werden.The side seals could, in principle, instead of being positioned laterally of the casting rolls by a manipulator 40, could also be arranged on the frame and be brought with it and the housing 30 into the maintenance position.

Im Prinzip könnten statt Schienen auch anderweitige Mittel für ein Verschieben des Rahmengestelles mit den Giessrollen vorgesehen sein, wie zum Beispiel Hängeschienen.In principle, instead of rails and other means for moving the frame could be provided with the casting rolls, such as hanging rails.

Das Gehäuse könnte auch auf durchgehenden, nicht absenkbaren Schienen geführt sein. Der Wasseranschluss müsste dann durch eine Steckverbindung, angepreßte Medienplatte oder ähnlichem ausgeführt sein.The housing could also be guided on continuous, non-lowerable rails. The water connection would then have to be made by a plug connection, pressed media plate or the like.
