Definitions
- the invention relates to a device for changing a pouring tube on a metallurgical vessel, in particular a tundish, in which the refractory pouring tube with a head plate can be placed on slide rails which are at least partially spring-loaded on the bottom of the vessel and can be moved into a pouring position with the aid of a drive unit.
- the pouring tube with its top plate lies sealingly in the region of the pouring opening of the vessel, and in which, if necessary by means of the new pouring tube with its top plate, the used pouring tube with its top plate can be transferred to a removal position with the aid of the drive unit, and with a refractory base plate (10), which can be placed on the bottom (4) of the vessel (2), optionally offset in height from one another, at least partially spring-loaded slide rails (5) and displaceable with the help of at least one drive unit (9) in the casting position , in which the pouring tube (1) with its head plate (3) lies sealingly against the base plate (10) and the base plate (10) in turn lies sealingly in the region of the pouring opening (7) of the vessel (2).
- a pouring tube changing device is known from EP-OS 0 192 019.
- the pouring tube is brought with its head plate on guide rails into a waiting position in front of the pouring position below the pouring opening of the metallurgical vessel and from there by means of a pusher device moved to the pouring position. If the pouring tube is used up, a new pouring tube is brought into the waiting position mentioned and then shifted into its pouring position with the aid of the pusher device, the used pouring tube being pressed from its pouring position into a removal position at the same time.
- the slide plate and the pouring tube with control plate are not interchangeable.
- the control cylinder is arranged on an intermediate piece, so that the pouring tube with the control plate alone cannot be brought into the control position by the control cylinder; this requires an additional pressure cylinder.
- a push-through operation for the pouring tube with control plate is not possible despite the relatively complex construction.
- the object of the present invention is to utilize the advantages of the changing device known per se, mentioned at the outset, but to provide them with a further possible use with essentially the same simple structure and economical operation.
- This object is essentially achieved in that, in addition to the used pouring tube with its top plate, optionally by means of the new pouring tube with its top plate, with the aid of the at least one drive unit, the used base plate, optionally by means of the new base plate, using the at least one drive unit in a removal position can be transferred that the maximum metal flow through the pouring opening of the vessel can be regulated to zero by moving the pouring tube with its top plate or the base plate, and that the respective drive unit for moving the pouring tube with its top plate or the base plate into the Casting position is used to control the metal flow.
- the device mentioned at the outset which was previously only suitable for replacing a pouring tube, at the same time has the function of a flow control for the metallurgical vessel, it being understood that the head plate is then appropriately dimensioned to match the pouring opening of the vessel to ensure, for example, that the pouring opening is closed completely and safely.
- the problem is solved particularly simply in that the drive unit for moving the pouring tube with its top plate or the base plate into the pouring position also serves to regulate the metal flow.
- the handling of the device according to the invention is made particularly simple if the drive unit can be detachably coupled to the pouring tube or to its top plate, so that not only a quick change of the pouring tube with its top plate, but also a reliable control of the metal flow is possible.
- the base plate and the pouring tube with its head plate can be displaced relative to one another, if necessary simultaneously. In this way it can be achieved, for example, that the position of the pouring jet does not shift when the metal flow changes.
- the pouring tube and head plate are preferably formed in one piece, that is to say without a joint.
- the slide rails are divided into individual spring-loaded rail sections 5', which engage under the head plate 3 at its edge and press the top of the head plate 3 'against the downward-facing sealing surface of the base plate 10.
- the pouring tube 1 already present in the middle pouring position is pushed to the right onto a slightly sloping rail section 5 '' into a removal position, in which the used pouring tube 1 '' can be removed .
- the pouring tube 1 'with its top plate 3' can be used according to the invention by means of the drive unit 6 by pushing it back and forth (which is indicated by double arrow R) to regulate the maximum metal flow through the pouring opening 7 of the vessel 2.
- the maximum metal flow can be regulated to zero on both sides.
- the base plate 10 is illustrated in the fully open casting position. With the aid of their horizontal displacement of the base plate 10, indicated by a double arrow, the maximum metal flow through the pouring opening 7 of the vessel 2 can also be regulated to zero, if necessary. This can be done with the help of the drive unit 9, which also serves to move the base plate 10 into the casting position shown. Just as is the case when changing the pouring tube 1, 1 ', 1' ', by pushing a new base plate 10 into the pouring position, the previously used base plate 10 can be pushed out of its pouring position into a removal position.

Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Wechseln eines Gießrohres an einem metallurgischen Gefäß, insbesondere Tundish, bei welcher das feuerfeste Gießrohr mit einer Kopfplatte auf am Boden des Gefäßes angeordneten, wenigstens bereichsweise federbelasteten Gleitschienen absetzbar und mit Hilfe eines Antriebsaggregats in eine Gießstellung verschieblich ist, in welcher das Gießrohr mit dessen Kopfplatte dichtend im Bereich der Ausgußöffnung des Gefäßes anliegt, und bei welcher, gegebenenfalls vermittels des neuen Gießrohres mit dessen Kopfplatte, das verbrauchte Gießrohr mit dessen Kopfplatte mit Hilfe des Antriebsaggregates in eine Entnahmestellung überführbar ist, sowie mit einer feuerfesten Grundplatte (10), die auf am Boden (4) des Gefäßes (2), gegebenenfalls höhenversetzt zueinander, angeordneten, wenigstens bereichsweise federbelasteten Gleitschienen (5) absetzbar und mit Hilfe mindestens eines Antriebsaggregates (9) in Gießstellung verschieblich ist, in welcher das Gießrohr (1) mit dessen Kopfplatte (3) dichtend an der Grundplatte (10) anliegt und die Grundplatte (10) ihrerseits dichtend im Bereich der Ausgußöffnung (7) des Gefäßes (2) anliegt.The invention relates to a device for changing a pouring tube on a metallurgical vessel, in particular a tundish, in which the refractory pouring tube with a head plate can be placed on slide rails which are at least partially spring-loaded on the bottom of the vessel and can be moved into a pouring position with the aid of a drive unit. in which the pouring tube with its top plate lies sealingly in the region of the pouring opening of the vessel, and in which, if necessary by means of the new pouring tube with its top plate, the used pouring tube with its top plate can be transferred to a removal position with the aid of the drive unit, and with a refractory base plate (10), which can be placed on the bottom (4) of the vessel (2), optionally offset in height from one another, at least partially spring-loaded slide rails (5) and displaceable with the help of at least one drive unit (9) in the casting position , in which the pouring tube (1) with its head plate (3) lies sealingly against the base plate (10) and the base plate (10) in turn lies sealingly in the region of the pouring opening (7) of the vessel (2).
Eine Gießrohrwechseleinrichtung ist aus der EP-OS 0 192 019 bekannt. Hierbei wird das Gießrohr mit seiner Kopfplatte auf Führungsschienen in eine Wartestellung vor der Gießstellung unterhalb der Ausgußöffnung des metallurgischen Gefäßes gebracht und von dort mittels einer Drückereinrichtung in die Gießstellung verschoben. Ist das Gießrohr verbraucht, wird ein neues Gießrohr in die erwähnte Wartestellung gebracht und dann mit Hilfe der Drückereinrichtung in seine Gießstellung verschoben, wobei gleichzeitig das verbrauchte Gießrohr aus seiner Gießstellung in eine Entnahmestellung gedrückt wird.A pouring tube changing device is known from EP-OS 0 192 019. Here, the pouring tube is brought with its head plate on guide rails into a waiting position in front of the pouring position below the pouring opening of the metallurgical vessel and from there by means of a pusher device moved to the pouring position. If the pouring tube is used up, a new pouring tube is brought into the waiting position mentioned and then shifted into its pouring position with the aid of the pusher device, the used pouring tube being pressed from its pouring position into a removal position at the same time.
Aus der DE-AS 20 27 881 ist eine Schieberverschlußanordnung an einem metallurgischen Gefäß bekannt, bei welcher jeweils eine Regelplatte mit einem Gießrohr in einer Einfassung aufgenommen ist, welche an Führungsleisten unterhalb des Gefäßes geführt ist. Erst wenn eine von zwei Schieberplatten in Durchflußstellung gebracht ist, kann das Gießrohr mit seiner Regelplatte mit Hilfe des Regelzylinders zur Regelung der Abflußgeschwindigkeit der Metallschmelze eingesetzt werden. Die Schieberplatte dient dabei lediglich dem Abschluß des Gefäßes oder dem vollen Durchgang der Metallschmelze, während die Regelung der Durchflußgeschwindigkeit der Metallschmelze in eine Kokille ausschließlich von dem Gießrohr mit dessen Regelplatte erfolgt. Die beiden Einheiten, bestehend aus Schieberplatte und Gießrohr mit Regelplatte, können jeweils lediglich als Ganzes ausgetauscht werden. Die Schieberplatte und das Gießrohr mit Regelplatte sind nicht unabhängig voneinander austauschbar. Der Regelzylinder ist an einem Zwischenstück angeordnet, so daß das Gießrohr mit der Regelplatte alleine von dem Regelzylinder nicht in Regelstellung gebracht werden kann; hierzu bedarf es jeweils eines weiteren Druckmittelzylinders. Ein Durchschubbetrieb für das Gießrohr mit Regelplatte ist trotz der verhältnismäßig aufwendigen Konstruktion nicht möglich.From DE-AS 20 27 881 a slide closure arrangement on a metallurgical vessel is known, in which in each case a control plate with a pouring tube is received in an enclosure, which is guided on guide strips below the vessel. Only when one of two slide plates is brought into the flow position can the pouring tube with its regulating plate be used with the help of the regulating cylinder to regulate the flow rate of the molten metal. The slide plate serves only to close the vessel or the full passage of the molten metal, while the regulation of the flow rate of the molten metal in a mold takes place exclusively from the pouring tube with its regulating plate. The two units, consisting of slide plate and pouring tube with control plate, can only be replaced as a whole. The slide plate and the pouring tube with control plate are not interchangeable. The control cylinder is arranged on an intermediate piece, so that the pouring tube with the control plate alone cannot be brought into the control position by the control cylinder; this requires an additional pressure cylinder. A push-through operation for the pouring tube with control plate is not possible despite the relatively complex construction.
Aufgabe der vorliegenden Erfindung ist es, die Vorteile der an sich bekannten, eingangs genannten Wechseleinrichtung zu nutzen, diese jedoch bei im wesentlichen gleichbleibendem einfachen Aufbau und wirtschaftlicher Betriebsweise einer weiteren Verwendungsmöglichkeit zuzuführen.The object of the present invention is to utilize the advantages of the changing device known per se, mentioned at the outset, but to provide them with a further possible use with essentially the same simple structure and economical operation.
Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß außer dem verbrauchten Gießrohr mit dessen Kopfplatte gegebenenfalls vermittels des neuen Gießrohres mit dessen Kopfplatte, mit Hilfe des wenigstens einen Antriebsaggregates auch die verbrauchte Grundplatte, gegebenenfalls vermittels der neuen Grundplatte, mit Hilfe des mindestens einen Antriebsaggregates in eine Entnahmestellung überführbar ist, daß durch das Verschieben des Gießrohres mit dessen Kopfplatte oder der Grundplatte der maximale Metalldurchfluß durch die Ausgußöffnung des Gefäßes bis auf Null regelbar ist, und daß das jeweilige Antriebsaggregat für das Verschieben des Gießrohres mit dessen Kopfplatte bzw. der Grundplatte in die Gießstellung der Regelung des Metalldurchflusses dient.This object is essentially achieved in that, in addition to the used pouring tube with its top plate, optionally by means of the new pouring tube with its top plate, with the aid of the at least one drive unit, the used base plate, optionally by means of the new base plate, using the at least one drive unit in a removal position can be transferred that the maximum metal flow through the pouring opening of the vessel can be regulated to zero by moving the pouring tube with its top plate or the base plate, and that the respective drive unit for moving the pouring tube with its top plate or the base plate into the Casting position is used to control the metal flow.
Dadurch erhält die eingangs genannte Einrichtung, welche bisher lediglich für das Auswechseln eines Gießrohres geeignet war, gleichzeitig die Funktion einer Durchflußregelung für das metallurgische Gefäß, wobei sich von selbst versteht, daß dann die Kopfplatte in Anpassung an die Ausgußöffnung des Gefäßes entsprechend dimensioniert ist, um beispielsweise auch ein vollständiges und sicheres Schließen der Ausgußöffnung zu gewährleisten. Die Aufgabe ist dadurch besonders einfach gelöst, daß das Antriebsaggregat für das Verschieben des Gießrohres mit dessen Kopfplatte bzw. der Grundplatte in die Gießstellung auch der Regelung des Metalldurchflusses dient.As a result, the device mentioned at the outset, which was previously only suitable for replacing a pouring tube, at the same time has the function of a flow control for the metallurgical vessel, it being understood that the head plate is then appropriately dimensioned to match the pouring opening of the vessel to ensure, for example, that the pouring opening is closed completely and safely. The problem is solved particularly simply in that the drive unit for moving the pouring tube with its top plate or the base plate into the pouring position also serves to regulate the metal flow.
Die Handhabung der erfindungsgemäßen Einrichtung wird dann besonders einfach gemacht, wenn das Antriebsaggregat an das Gießrohr bzw. an dessen Kopfplatte lösbar ankoppelbar ist, so daß nicht nur ein schneller Wechsel des Gießrohres mit dessen Kopfplatte, sondern auch eine zuverlässige Regelung des Metalldurchflusses möglich ist.The handling of the device according to the invention is made particularly simple if the drive unit can be detachably coupled to the pouring tube or to its top plate, so that not only a quick change of the pouring tube with its top plate, but also a reliable control of the metal flow is possible.
Im Rahmen dieses Erfindungsgedankens kann es von Vorteil sein, daß aus Platz- oder Bedienungsgründen die Bewegungsrichtungen des Gießrohres und der Grundplatte gleich oder gegeneinander versetzt sind.Within the scope of this inventive concept, it can be advantageous that the directions of movement of the pouring tube and the base plate are the same or offset from one another for reasons of space or operation.
Es kann auch von Vorteil sein, wenn Grundplatte und Gießrohr mit dessen Kopfplatte gegeneinander, gegebenenfalls gleichzeitig, verschiebbar sind. Hierdurch kann beispielsweise erreicht werden, daß sich bei Änderung des Metalldurchflusses die Lage des Gießstrahls nicht verschiebt.It may also be advantageous if the base plate and the pouring tube with its head plate can be displaced relative to one another, if necessary simultaneously. In this way it can be achieved, for example, that the position of the pouring jet does not shift when the metal flow changes.
Gießrohr und Kopfplatte sind aus Sicherheitsgründen vorzugsweise einstückig, also ohne Fuge, ausgebildet.For safety reasons, the pouring tube and head plate are preferably formed in one piece, that is to say without a joint.
Nachfolgend werden Ausführungsbeispiele der Erfindung anhand der Zeichnung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawing.

Nachdem das Gießrohr 1 in die linke Wartestellung auf den Gleischienen 5 aufgesetzt worden ist, kann es mit Hilfe eines am Boden 4 des Gefäßes 2 angebrachten Antriebsaggregates 6 in die mittlere Gießstellung verschoben werden, in welcher die Ausgußöffnung 7 des Gefäßes 2 mit dem Durchflußkanal 11 des Gießrohres 1 fluchtet. Beim Einschieben eines neuen Gießrohres 1 aus der linken Wartestellung in die mittlere Gießstellung wird das in der mittleren Gießstellung bereits vorhandene Gießrohr 1 nach rechts auf einen leicht abfallenden Schienenabschnitt 5'' in eine Entnahmestellung geschoben, in welcher das verbrauchte Gießrohr 1'' entnommen werden kann.In the region of the pouring position of the head plate 3 ', the slide rails are divided into individual spring-loaded rail sections 5', which engage under the
