Description

Die Erfindung betrifft einen Schiebeverschluss für metallurgische Gefässe gemäss dem Oberbegriff des Anspruches 1 sowie eine Ausgusshülse für einen Schiebeverschluss nach Anspruch 6.The invention relates to a sliding closure for metallurgical vessels according to the preamble of claim 1 and a spout for a sliding closure according to claim 6.

Schiebeverschlusse dieser Art sind in verschiedenen Ausgestaltungen bekannt. Sie enthalten mindestens zwei gegeneinander verspannbare feuerfeste Verschlussplatten, von denen eine in einer Schiebereinheit angeordnet ist und zum Öffnen und Schliessen einer Ausgussöffnung dient. Durch Längsverschieben der Schiebereinheit kann der Auslass in eine Drossel-oder Schliessstellung gebracht werden und somit ein geregeltes Abgiessen der Schmelzmenge aus dem Gefäss erfolgen.Sliding shutters of this type are known in various embodiments. They contain at least two mutually bracing refractory closure plates, one of which is arranged in a slide unit and is used to open and close a spout opening. By longitudinal displacement of the slide unit, the outlet can be brought into a throttle or closed position and thus a controlled pouring of the melt quantity from the vessel.

Die EP 1 119 428 B1 offenbart einen Schiebeverschluss mit einer feststehenden feuerfesten Verschlussplatte und einer dieser gegenüber verschiebbaren Schieberplatte. Mit der Schieberplatte ist eine auswechselbare feuerfeste Ausgusshülse verspannbar, die mittels eines Verspannungsorgans an diese Schieberplatte angepresst wird und zusammen mit dieser einen Teil der Schiebereinheit bildet.The EP 1 119 428 B1 discloses a sliding closure with a fixed refractory closure plate and a slide plate which is displaceable relative thereto. With the slide plate is a replaceable refractory Spout sleeve clamped, which is pressed by means of a tensioning element to this slide plate and forms a part of the slide unit together with this.

Bei einem aus EP 0 891 829 bekannten Schiebeverschluss ist eine Schieberplatte zwischen einer oberen und einer unteren feststehenden Verschlussplatte verschiebbar angeordnet. In diesem Fall ist die auswechselbare feuerfeste Ausgusshülse mit der unteren feststehenden Verschlussplatte verspannbar.At one off EP 0 891 829 known slide closure is a slide plate slidably disposed between an upper and a lower fixed closure plate. In this case, the replaceable refractory spout is clamped with the lower fixed closure plate.

Zur Abdichtung wird zwischen die Stirnflächen der Ausgusshülse und der mit dieser verspannbaren Verschlussplatte (Schieberplatte oder die untere feststehende Verschlussplatte) Mörtel eingebracht. Es ist dabei von Nachteil, dass der Mörtel beim Anpressen der Ausgusshülse an die Verschlussplatte stellenweise entweichen kann, was zur Bildung von undichten Stellen führt.For sealing, mortar is introduced between the end faces of the pouring spout and the closure plate which can be braced with it (slide plate or the lower fixed closure plate). It is disadvantageous that the mortar can escape in places when pressing the spout to the closure plate, which leads to the formation of leaks.

In der Druckschrift US-A-3,877,675 ist ein Schiebeverschluss angedeutet, bei welchem eine ringförmige Abdichtung zwischen einer oberen Verschlussplatte und einer feuerfesten Hülsenanordnung am Ausguss eines Metallschmelze enthaltenden Behälters vorgesehen ist. Diese Abdichtung besteht aus einem in den ringförmigen Spalt der Verschlussplatte und/oder der Hülsenanordnung einlegbaren Hülle mit einem Mörtel darin. Nachteilig bei dieser Dichtungsanordnung und insbesondere bei diesem Spalt ist die Schwächung der feuerfesten Platte und/oder der Hülsenanordnung, die einer enormen Hitze ausgesetzt sind.In the publication US-A-3,877,675 a sliding closure is indicated in which an annular seal between an upper closure plate and a refractory sleeve assembly is provided at the spout of a molten metal containing container. This seal consists of an insertable into the annular gap of the closure plate and / or the sleeve assembly shell with a mortar therein. A disadvantage of this seal arrangement and in particular in this gap is the weakening of the refractory plate and / or the sleeve assembly, which are exposed to a tremendous heat.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Schiebeverschluss zu schaffen, bei dem Leckagen zwischen der Ausgusshülse und der mit dieser verspannbaren Verschlussplatte weitgehend vermieden werden. Zum gleichen Zweck soll eine Ausgusshülse für einen Schiebeverschluss geschaffen werden.The present invention has for its object to provide a sliding closure, in which leaks between the spout and the brace with this closure plate are largely avoided. For the same purpose a spout for a sliding closure is to be created.

Diese Aufgabe wird erfindungsgemäss durch einen Schiebeverschluss mit den Merkmalen des Anspruches 1 sowie durch eine Ausgusshülse mit den Merkmalen des Anspruches 6 gelöst.This object is achieved by a sliding closure with the features of claim 1 and by a spout with the features of claim 6.

Weitere bevorzugte Ausgestaltungen des erfindungsgemässen Schiebeverschlusses bilden den Gegenstand der abhängigen Ansprüche.Further preferred embodiments of the inventive sliding closure form the subject of the dependent claims.

Beim erfindungsgemässen Schiebeverschluss weist die Ausgusshülse und/oder die mit dieser verspannbare Verschlussplatte einen stirnseitig vorstehenden, ringförmigen Umfangskragen auf, der eine die Ausgussöffnung umgebende Vertiefung zur Aufnahme von Dichtungsmaterial umschliesst. Beim Verspannen der Ausgusshülse mit der Verschlussplatte wird die Ausgusshülse mit dem Umfangskragen an die Verschlussplatte angepresst. Dabei verbleibt das Dichtungsmaterial in der Vertiefung, so dass eine einwandfreie Abdichtung ohne Leckagen zwischen der Ausgusshülse und der Verschlussplatte gewährleistet ist.In the sliding closure according to the invention, the pouring sleeve and / or the closure plate which can be braced with the latter have an annular peripheral collar projecting on the front side, which encloses a recess surrounding the pouring opening for receiving sealing material. When clamping the spout with the closure plate, the spout is pressed with the peripheral collar to the closure plate. In this case, the sealing material remains in the recess, so that a perfect seal without leakage between the spout and the closure plate is guaranteed.

Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Fig. 1
ein Ausführungsbeispiel eines erfindungsgemässen Schiebeverschlusses im Querschnitt; und
Fig. 2
eine Ausführungsform einer mit einer Verschlussplatte verspannbaren Ausgusshülse.
The invention will be explained in more detail with reference to the drawing. Show it:
Fig. 1
an embodiment of a sliding closure according to the invention in cross section; and
Fig. 2
an embodiment of a spanned with a closure plate spout.

Fig.1 zeigt einen Schiebeverschluss 1 eines metallurgischen Gefässes, bei dem es sich beispielsweise um eine in einer Stranggiessanlage verwendete Pfanne handelt, in die Stahlschmelze gefüllt wird. Vom Gefäss selber sind in Fig. 1 lediglich der äussere Stahlmantel 2 sowie eine feuerfeste Einlaufhülse 4 veranschaulicht. Die Einlaufhülse 4 bildet den ersten Teil einer Ausgussöffnung 5. Fig.1 shows a sliding closure 1 of a metallurgical vessel, which is for example a pan used in a continuous casting plant, is filled into the molten steel. From the vessel itself are in Fig. 1 only the outer steel shell 2 and a refractory inlet sleeve 4 illustrates. The inlet sleeve 4 forms the first part of a spout opening 5.

Der Schiebeverschluss 1 weist einen am Gefäss montierten Gehäuseteil 7 auf, in dem eine an der Hülse 4 dichtend anliegende, feststehende feuerfeste Verschlussplatte 10 befestigt ist. In einer Schiebereinheit 9 des Schiebeverschlusses 1 wird eine feuerfeste Schieberplatte 11 gehalten, die zum Öffnen und Schliessen der Ausgussöffnung 5 dient.The sliding closure 1 has a housing part 7 which is mounted on the vessel and in which a fixed refractory closure plate 10 which bears sealingly against the sleeve 4 is fastened. In a slide unit 9 of the sliding closure 1, a refractory slide plate 11 is held, which serves to open and close the spout opening 5.

Durch ein Längsverschieben der Schiebereinheit 9 mittels eines Antriebsorganes 6 und der darin eingesetzten Schieberplatte 11 kann der Pfannenauslass aus der in der Zeichnung veranschaulichten Öffnungsstellung in eine Drossel- oder Schliessstellung gebracht werden. Die Art und Weise, wie die Schiebereinheit 9 auf entsprechenden Führungsbahnen des Gehäuseteils 7 geführt und dabei die Schieberplatte 11 mittels dafür vorgesehener Federorgane an die feststehende Verschlussplatte 10 angepresst wird, ist an sich bekannt und wird daher nicht näher beschrieben.By a longitudinal displacement of the slide unit 9 by means of a drive member 6 and the slide plate 11 inserted therein, the ladle outlet can be brought from the illustrated in the drawing open position in a throttle or closed position. The manner in which the slide unit 9 is guided on corresponding guideways of the housing part 7 and thereby the slide plate 11 is pressed by means provided therefor spring members to the fixed closure plate 10 is known per se and is therefore not described in detail.

An die Schieberplatte 11 schliesst eine auswechselbare feuerfeste Ausgusshülse 16 an. Diese wird mittels eines Verspannungsorgans 17 an die Schieberplatte 11 angepresst. In der Regel steht das auf die Ausgusshülse 16 einwirkende Verspannungsorgan 17 in einer bajonettartigen Verbindung mit der Schiebereinheit 9.To the slide plate 11 includes a replaceable refractory spout 16. This is pressed by means of a tensioning member 17 to the slide plate 11. In general, the tensioning sleeve 17 acting on the spout 16 is in a bayonet-type connection with the spool unit 9.

Erfindungsgemäss weist die Ausgusshülse 16 einen stirnseitig vorstehenden, ringförmigen Umfangskragen 20 auf, der eine die Ausgussöffnung 5 umgebende stirnseitige Vertiefung 21 der Ausgusshülse 16 umschliesst. Die Vertiefung 21 ist zur Aufnahme von Dichtungsmaterial vorgesehen. Dieses kann in die Vertiefung 21 direkt eingetragen oder aber auch in einer Folie bzw. einer scheibenförmigen Kassette, die bei Erhitzung schmilzt, eingelegt werden. Beim Dichtungsmaterial handelt es sich in der Regel um Mörtel, es könnten aber auch andere Materialkombinationen oder filzartige Einlagen verwendet werden. Beim Verspannen der Ausgusshülse 16 mit der Schieberplatte 11 wird die Ausgusshülse 16 mit dem Umfangskragen 20 an die Schieberplatte 11 angepresst. Dabei verbleibt das Dichtungsmaterial in der Vertiefung 21, so dass eine einwandfreie Abdichtung ohne Leckagen zwischen der Ausgusshülse 16 und der Schieberplatte 11 gewährleistet ist.According to the invention, the spout 16 has a frontally projecting, annular peripheral collar 20, which encloses a front-side recess 21 of the spout 16 surrounding the spout opening 5. The recess 21 is provided for receiving sealing material. This can be entered directly into the depression 21 or else in one Slide or disc-shaped cassette, which melts when heated, are inserted. When sealing material is usually mortar, but it could also be used other combinations of materials or felt-like deposits. When clamping the spout 16 with the slide plate 11, the spout 16 is pressed with the peripheral collar 20 to the slide plate 11. In this case, the sealing material remains in the recess 21, so that a perfect seal without leaks between the spout 16 and the slide plate 11 is ensured.

Fig. 2 zeigt eine Variante, bei welcher die Schieberplatte 11' einen stirnseitigen Vorsprung 23 aufweist, der in die Vertiefung 21' der Ausgusshülse 16' hineinragt, wobei seine Umfangsfläche 24 an der Innenfläche 25 anschlägt und seine Stirnfläche 26 in einem Abstand zum Boden 27 der Vertiefung 21' liegt. Mit Vorteil verläuft die Umfangsfläche 24 des Vorsprungs 23 sowie die Innenfläche 25 des Umfangskragens 20' bzw. der Vertiefung 21' konisch, sich in Richtung zum Boden 27 der Vertiefung 21' hin verjüngend. Fig. 2 shows a variant in which the slide plate 11 'has a front projection 23 which projects into the recess 21' of the spout 16 ', wherein its peripheral surface 24 abuts against the inner surface 25 and its end face 26 at a distance from the bottom 27 of the recess 21st ' lies. Advantageously, the circumferential surface 24 of the projection 23 and the inner surface 25 of the circumferential collar 20 'and the recess 21' is conical, tapering in the direction of the bottom 27 of the recess 21 'out.

Es wäre durchaus möglich, den stirnseitig vorstehenden, ringförmigen Umfangskragen und die Vertiefung zur Aufnahme von Dichtungsmaterial der Schieberplatte zuzuordnen und die Ausgusshülse stirnseitig flach auszubilden oder mit einem Vorsprung zu versehen. Theoretisch könnte auch sowohl die Schieberplatte als auch die Ausgusshülse einen Umfangskragen und eine Vertiefung aufweisen. Es ist jedoch fertigungstechnisch am vorteilhaftesten, wenn die Ausgusshülse mit der Vertiefung und mit dem Umfangskragen versehen ist.It would be quite possible to assign the frontally projecting, annular peripheral collar and the recess for receiving sealing material of the slide plate and form the spout sleeve end face flat or provided with a projection. Theoretically, both the slide plate and the spout sleeve could have a circumferential collar and a recess. However, it is the most advantageous in terms of production engineering when the spout is provided with the recess and with the peripheral collar.

In Fig. 1 dargestellt und vorstehend beschrieben wurde ein lediglich eine feststehende Verschlussplatte umfassender Schiebeverschluss, bei dem die Ausgusshülse mit der Schieberplatte verspannt wird und zusammen mit dieser einen Teil der Schiebereinheit bildet. Die erfindungsgemässe, mit dem stirnseitig vorstehenden ringförmigen Umfangskragen und mit der stirnseitigen, vom Umfangskragen umschlossenen und die Ausgussöffnung umgebenden Vertiefung versehene Ausgusshülse könnte selbstverständlich auch bei einem Schiebeverschluss, der zwei feststehende Verschlussplatten und eine dazwischen angeordneten Schieberplatte umfasst, Verwendung finden und in diesem Fall dann statt mit der Schieberplatte mit der unteren feststehenden Verschlussplatte verspannt werden.In Fig. 1 has been shown and described above, only a fixed closure plate comprehensive sliding closure, in which the spout sleeve is clamped to the slide plate and forms together with this part of the slide unit. The inventive, provided with the frontally projecting annular peripheral collar and the frontal, surrounded by the peripheral collar and the spout surrounding recess Ausgusshülse could of course also in a sliding closure comprising two fixed closure plates and a valve plate arranged therebetween, find use and in this case then instead be clamped with the slide plate with the lower fixed closure plate.
