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. Die Erfindung betrifft auch ein Verfahren zum Wechseln der Gießrollen.The invention relates to a strip casting machine for producing a metal strip, with two juxtaposed, forming a casting gap Casting rolls, which are rotatably mounted on a framework set, wherein the Casting frame carrying rails on rails from the casting position in one Maintenance position and vice versa is displaced. The invention also relates to a Method for changing the casting rolls.

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 casters with two substantially parallel casting rolls Narrow sides limit the casting gap. When casting ribbons, in particular of steel bands, the narrow sides become both due to friction the casting rolls as well as in the lower part by the friction of the solidified band due to abrasive wear and must be replaced in a pouring break. At the Change the narrow sides of the casting position, in which the Narrow sides and bales abut, essentially horizontally by means of Anstellreinrichtung moved away from the bale in a pitching position and then by means of narrow side change device z. B. robots on each Machine side are arranged on the casting platform, upwards from the setting position away. 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 strip casting machines, the casting rolls are stationary and firmly below a turret and a distribution vessel or the like arranged. Now if these casting rolls revised, for example, by regrinding or need to be replaced, this is with elaborate dismantling or Assembly work connected, which makes these casting rollers difficult to access are due to their weight carried away with a crane or millimeters must be used exactly again. Also the arrival or decoupling of Water connections or electrical connection lines is due to the existing accessibility associated with cumbersome work processes, at where 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 that during the maintenance or maintenance of the casting rolls and The machine can not be poured and thus the casting capacity of the plant 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 stored on a cart, which in turn on Rails slidable by approximately half the length of the carriage by means of a cylinder is. This version of the strip casting machine is suitable only for smaller casting rolls diameter. Even in the pushed away from the casting position Maintenance position, the accessibility of the casting rolls is only marginally better, because this 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 is a strip casting machine with two casting rolls shown. The casting rolls are provided with side seals and on one Carriage mounted. In the casting position, liquid metal is transformed from a distributor poured the space between the casting rolls. From the casting gap between the Casting rolls, the solidified metal strip is pulled off laterally down and closed wrapped up a metal collar. In a heating position, which is half a carriage length located laterally to the casting position, the side seals and heated the pouring tube in ovens and connected to the casting rolls. Subsequently If the car is driven immediately from the heating station in the casting station, in which the tape 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.By contrast, the object of the present invention is to provide To create a strip casting machine according to the type mentioned in, at the optimal accessibility to the machine and especially to the Casting is possible by means of a quick maintenance or a change of the same and in which the availability of the strip casting machine for the Potting and thus the casting capacity of the same can be increased.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, dass das Rahmengestell mit den Gießrollen auf den Schienen oder anderweitigen Mitteln für ein Verschieben entlang der Drehachsen der Gießrollen um eine solche Distanz von der Gießposition weg verschiebbar ist, dass ein zweites mit vorbereiteten Gießrollen versehenes Rahmengestell auf den Schienen in die Gießposition verschiebbar ist.The object is inventively achieved in that the frame with the casting rolls on the rails or other means for displacement along the axes of rotation of the casting rolls displaceable by such a distance from the casting position is that a second provided with prepared cast rolls frame on the rails in the casting position is displaceable.

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 Rahmengestellt drehbar gelagert sind und das Rahmengestell, ggf. mit dem Gehäuse um die genannte Distanz von der Gießposition weg verschiebbar ist und ein zweites mit vorbereiteten Gießrollen versehenes Rahmengestell bzw. Gehäuse in die Gießposition verschiebbar ist.With this embodiment of the strip casting machine according to the invention, in which the Casting rollers slidable in a maintenance position remote from the casting position and can be replaced immediately by other prepared casting rolls considerable advantages over the known systems. This is especially true when the casting rolls are rotatably mounted on a frame are and the frame, possibly with the housing by the distance of the casting position is displaced away and a second with prepared casting rolls provided frame or housing is displaceable in the casting position.

Durch das Verschieben des Rahmengestells mit den Gießrollen ggf. mit dem Gehäuse zu einem Wartungsplatz können bei diesem Werkzeuge, Lehren, Nachbearbeitungsgeräte, Mess- und andere Kontrollgeräte stationär eingerichtet werden. By moving the frame with the casting rolls possibly with the housing to a maintenance place can in this tools, gauges, post-processing equipment, Measuring and other control devices are set up stationary.

Dies erlaubt ein schnelles und außerdem professionelles Warten und Wiederinstandstellen der Maschine. Nach dem Wegfahren eines Rahmengestelles oder des Gehäuses mit Rahmengestell zum Beispiel beim Wechsel der Gießrollen mit anderen Breiten oder bei nicht mehr funktionstüchtigen Gießrollen, können sofort vorbereitete Gießrollen auf einem anderen Rahmengestell 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 the machine. After driving away a frame or the housing with frame, for example, when changing the casting rolls with other widths or no longer functioning cast rolls, can immediately prepared casting rolls on another frame below the distribution vessel be brought and it can thereby cast a metal band or continue to be poured.
