Description

Die Erfindung betrifft eine Ausgußvorrichtung für Schiebersysteme, die beispielsweise bei Stahl-Gießpfannen Anwendung finden, mit einem im wesentlichen zylindrischen Blechmantel, der an seiner Innenseite eine feuerfeste Auskleidung aufweist, und einer Befestigungsvorrichtung, mit der die Ausgußvorrichtung an einer Schieberplatte befestigt ist, wobei der Blechmantel und die Befestigungsvorrichtung einteilig miteinander verbunden sind, wobei der Blechmantel und die feuerfeste Auskleidung im Bereich der Befestigungsvorrichtung eine gleichbleibende Wandstärke aufweisen.The invention relates to a pouring device for slide systems, the for example in steel ladles, with an im essentially cylindrical sheet metal jacket that has a fire-resistant inside Has liner, and a fastening device with which the Pouring device is attached to a slide plate, the sheet metal jacket and the fastening device are integrally connected to one another, the Sheet metal jacket and the fireproof lining in the area of Fastening device have a constant wall thickness.

Aus der DE 33 28 901 A1 sind gattungsgemäße Ausgießvorrichtungen für Schiebersysteme bekannt, die ein im wesentlichen zylindrisches Rohr aus Stahlblech aufweisen, das an seinem einer Stahl-Gießpfanne zugewandten Ende einen Kragen aufweist. Über das Rohr wird ein ringförmiger Tragring derart geschoben, daß der Tragring an der Kragenfläche anliegt und mit an dem Tragring angeordneten Nocken in eine an der Schieberplatte angeordnete Kulisse eingreift. Das Rohr ist an seiner Innenseite mit feuerfestem Material ausgekleidet.DE 33 28 901 A1 are generic pouring devices for Slider systems are known which consist of a substantially cylindrical tube Have sheet steel, the end facing a steel ladle has a collar. An annular support ring becomes like this over the tube pushed that the support ring rests on the collar surface and with the support ring arranged cams engages in a backdrop arranged on the slide plate. The inside of the tube is lined with refractory material.

Nachteil dieser Ausgußvorrichtung ist, daß eine Vergrößerung des Gießdurchmessers nur in Verbindung mit einer größeren Schieberplatte oder unter Inkaufnahme einer Verringerung der Wandungsstarke der Feuerfestauskleidung möglich ist. Die Verwendung einer größeren Schieberplatte hat jedoch den Nachteil, daß die Schieberplatte aus feuerfestem Material sehr kostenintensiv ist. Andererseits ist eine Verringerung der Wandungsstärke der feuerfesten Auskleidung aus Sicherheitsgründen nur in sehr beschränktem Maße möglich. Zum einen wird durch die Verringerung der Auskleidungsstärke die Wärmeisolierung sehr starkgemindert und zum anderen besteht durch diese Verringerung der Wandungsstärke eine erhöhte Stahldurchbruchgefahr. Auch kann eine Ausgußvorrichtung mit einer dünnwandigen Feuerfestauskleidung nur Wenige Male wiederverwendet werden, da der durchfließende Stahl einen hohen Verschleiß der Auskleidung erzeugt.The disadvantage of this pouring device is that it is enlarged of the casting diameter only in connection with a larger slide plate or at a price a reduction in the wall thickness of the refractory lining is possible. The use of a larger one Slider plate has the disadvantage, however, that the slider plate made of fireproof material very expensive is. On the other hand there is a reduction in wall thickness the fireproof lining for safety reasons only possible to a very limited extent. On the one hand is reduced by reducing the lining thickness Thermal insulation very much reduced and secondly exists through this reduction in wall thickness an increased risk of steel breakthrough. Also one can Pouring device with a thin-walled refractory lining can only be reused a few times because the steel flowing through is subject to high wear Lining created.

Die Verwendung eines Tragrings in Form eines Bajonetts zur Befestigung der Ausgußvorrichtung an der Schieberplatte hat den Nachteil, daß diese Konstruktion nur eine sehr geringe Stabilität aufweist. Ferner kommt es durch das Bajonett zu mechanischen Belastungen der Ausgußvorrichtung, die wiederum eine verstärkte Rißbildung in der feuerfesten Auskleidung nach sich ziehen. Aus dieser Rißbildung resultieren wiederum eine geringe Wiederverwendbarkeit der Ausgußvorrichtung und eine hohe Stahldurchbruchgefahr.The use of a support ring in the form of a bayonet for fastening the pouring device to the Slider plate has the disadvantage that this construction has very little stability. Further comes mechanical loads through the bayonet the pouring device, which in turn is reinforced Crack formation in the refractory lining. This crack formation results in turn low reusability of the pouring device and a high risk of steel breakthrough.

Ein Schiebersystem im Ausgußbereich einer Stahl-Gießpfanne ist in der FR-A 2 565 859 offenbart. Die Ausgußvorrichtung des in der FR-A 2 565 859 beschriebenen Systems umfaßt ein völlig unverkleidetes rohrförmiges Ausgußelement aus feuerfestem Material. Dieses nicht mit einem Metallmantel versehene Element weist im Bereich des unteren Drittels einen Nockenring oder zumindest ringförmig angeordnete Nocken auf. Zur Befestigung des Elementes im Schiebersystem weist das Schiebersystem eine obere federgelagerte Platte auf, an welcher ein Hülsenabschnitt angeordnet ist. In diesen Hülsenabschnitt wird das Element eingeschoben und mit einer Zwischenhülse in dieser Position gehalten, wobei die Zwischenhülse mit dem oberen Hülsenabschnitt verschraubt wird und an der entgegengesetzten, unteren Stirnfläche einen Ring aufweist, welcher als Anlage für den Nockenring oder die ringförmig angeordneten Nocken des Elementes dient. Da das Element ausschließlich aus feuerfestem Material besteht, können über den Nockenring bzw. die Nocken keine Kräfte übertragen werden. Auf die Zwischenhülse wird der sogenannte Schlüssel geschraubt, welcher ein Gegenlagermundstück an das Element heranführt, welches dann zwischen der oberen Schieberplatte und dem Gegenlagermundstück verklemmt und damit als Ausgußsystem fixiert wird.A slide system in the pouring area of a steel ladle is disclosed in FR-A 2 565 859. The pouring device that described in FR-A 2 565 859 Systems includes a completely undisguised tubular pouring element made of refractory material. This element not provided with a metal jacket has a cam ring in the lower third or at least cams arranged in a ring. For Attachment of the element in the slide system points the slide system has an upper spring-loaded plate on which a sleeve section is arranged. In the element is inserted into this sleeve section and held in this position with an intermediate sleeve, the intermediate sleeve with the upper sleeve portion is screwed and on the opposite, lower end face has a ring which as System for the cam ring or the ring-shaped arrangement Serves cams of the element. Because the element consists exclusively of refractory material No forces are transmitted via the cam ring or cams become. The so-called Screwed key, which one Counter bearing mouthpiece leads to the element which then between the upper slide plate and the Counter bearing mouthpiece jammed and thus as a pouring system is fixed.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, unter Meidung der zuvor genannten Nachteile eine Ausgußvorrichtung zu schaffen, die schnell und einfach an einer Schieberplatte befestigbar ist und die auch nach mehrmaliger Verwendung eine hohe Sicherheit gegen Stahldurchbruch aufweist.On the basis of this prior art, the object of the invention is to avoid the aforementioned disadvantages by creating a pouring device which can be quickly and easily attached to a slide plate and which, even after repeated use, has a high level of security against steel breakthrough.

Ferner wird mit der erfindungsgemäßen Ausgußvorrichtung eine gleichbleibende Isolierung über die gesamte Länge des zylindrischen Blechmantels erzielt. Auch wird der Blechmantel nicht durch einen Adapter oder einen Bajonettring auf der Außenseite belastet, so daß es hier nicht zu Rissen in der feuerfesten Auskleidung kommen kann.This configuration increases the risk of steel breakthrough reduced because the wall thickness remains the same the refractory lining none Has weak areas. Furthermore, with the invention Pouring device a constant Insulation along the entire length of the cylindrical sheet metal jacket achieved. Also the sheet metal jacket not through an adapter or a bayonet ring burdened on the outside, so it's not too here Cracks in the refractory lining can come up.

Eine einfache Befestigung wird dadurch erzielt, daß die Befestigungsvorrichtung mehrere Nocken aufweist, die im wesentlichen rechteckig ausgebildet und an dem Blechmantel befestigt sind. Eine besonders einfache Befestigung läßt sich dadurch erzielen, daß die Nocken einen Kragen aufweisen, der an dem Blechmantel anliegt und mit diesem verbunden ist.A simple attachment is achieved in that the fastening device has a plurality of cams, which are essentially rectangular and on the Sheet metal jacket are attached. A particularly simple one Attachment can be achieved in that the cams have a collar on the sheet metal jacket is present and connected to it.

Bei einer bevorzugten Ausführungsform der Erfindung weist der Blechmantel Öffnungen auf, in die die Nocken von innen her eingesetzt sind und mit dem Kragen an der Innenwand des Blechmantels anliegen. Bei dieser Ausgestaltung ist die Montage der Nocken sehr einfach, da die Nocken lediglich in die zuvor ausgestanzten Öffnungen des Blechmantels eingelegt werden und anschließend mit dem Blechmantel verbunden werden. Durch die Formgebung der Nocken und der Öffnungen sowie durch den an den Nocken angeordneten Kragen ist such eine maschinelle Fertigung der Ausgußvorrichtung möglich.In a preferred embodiment of the invention the sheet metal jacket has openings into which the Cams are inserted from the inside and with the collar lie against the inner wall of the sheet metal jacket. At this configuration is the assembly of the cams very easy, because the cams are only in the previously punched out Openings of the sheet metal jacket are inserted and then be connected to the sheet metal jacket. Due to the shape of the cams and the openings as well as the collar arranged on the cams is such a mechanical production of the pouring device possible.

Eine leichte Montage der Ausgußvorrichtung in der an der Schieberplatte angeordneten Kulisse wird dadurch erzielt, daß die im wesentlichen rechteckigen Nocken an ihrer Unterseite eine Schrägfläche haben, welche bei der Montage der Ausgußvorrichtung an der Schieberplatte auf einer entsprechenden Kulissenbahn gleitet.Easy assembly of the pouring device in the on the slide plate arranged backdrop achieved in that the substantially rectangular Cams have an inclined surface on their underside, which when mounting the pouring device on the Slider plate on a corresponding slide slides.

Die Nocken sind vorzugsweise im regelmäßigen Abstand an dem Blechmantel befestigt. Eine besonders vorteilhafte Ausgestaltung ergibt sich, wenn drei Nocken jeweils um 120° versetzt an dem Blechmantel befestigt sind. Hierdurch ist eine kostengünstige Herstellung der Ausgußvorrichtung möglich, die eine ausreichende Stabilität der Ausgußvorrichtung an der Schieberplatte gewährleistet und ferner mit ausreichender Stabilität in der Kulisse führbar ist.The cams are preferably regular Distance attached to the sheet metal jacket. A special one advantageous embodiment results when three cams each attached to the sheet metal jacket offset by 120 ° are. This is an inexpensive manufacture of Pouring device possible, which has sufficient stability the pouring device on the slide plate guaranteed and also with sufficient stability in the backdrop is feasible.

Um die Montage der Ausgußvorrichtung an der Schieberplatte bzw. die Demontage der Ausgußvorrichtung zu vereinfachen ist es vorteilhaft, wenn der Blechmantel mehrere Nocken aufweist, die punkt- oder achsensymmetrisch ausgebildet sind und in Öffnungen des Blechmantels befestigt sind, die unterhalb der Öffnungen für die Nocken zur Befestigung der Ausgußvorrichtung angeordnet sind. An diesen zweiten Nocken wird ein Werkzeug angesetzt, mit dessen Hilfe die Ausgußvorrichtung in die an der Schieberplatte angeordneten Kulisse eingedreht oder aus dieser herausgedreht werden kann. Dieses Werkzeug kann beispielsweise eine manuell oder elektrohydraulisch angetriebene Zange sein. Bei einer Weiterbildung der erfindungsgemäßen Ausgußvorrichtung sind die Nocken für den Ansatz eines Werkzeugs kreisförmig ausgebildet.To mount the spout on the Slider plate or the disassembly of the pouring device To simplify it is advantageous if the sheet metal jacket has several cams, the point or are axisymmetric and in openings of the sheet metal jacket are attached below the openings for the cams for fastening the pouring device are arranged.

Hierdurch ist gewährleistet, daß die Nocken mit einer ausreichenden Festigkeit mit dam Blechmantel verbunden sind und daß durch den Schweißvorgang kein großer Verzug des zum Teil sehr dünnwandigen Bleches auftritt.The cams are preferably spot welded attached to the sheet metal jacket. This is ensures that the cams with sufficient Strength associated with dam sheet metal jacket and that due to the welding process, there is no great delay in the Part of very thin-walled sheet occurs.

Bei einer Weiterentwicklung dar erfindungsgemäßen Ausgußvorrichtung ist vorgesehen, daß der Blechmantel an seinem der Schieberplatte zugewandten Ende aine Ringnut aufweist. Diese Ringnut, welche beispielsweise als Innensicke ausgebildet ist, dient dar Versteifung des Blechmantels und ermöglicht eine gleichmäßig auf die Innenfläche des Blechkörpers aufgetragene Auskleidung aus feuerfestem Material.In a further development of the invention Pouring device is provided that the sheet metal jacket on its facing the slide plate End has a ring groove. This ring groove, which for example is designed as an inner bead, serves to reinforce of the sheet metal jacket and enables one evenly applied to the inner surface of the sheet metal body Refractory lining.

Schließlich wird bei einar Weiterentwicklung erfindungsgemäß vorgeschlagen, daß der Blechmantel an seinem unteren Ende mindestens eine um den Blechmantel umlaufende Aufwölbung, vorzugsweise eine Außensicke aufweist. Mit dieser Aufwölbung wird die Wärmeübertragung zwischen dam Blechmantel und des beim Gießan des flüssigen Stahls in diesem Bereich angeordneten Anschlußstücks unterbrochen.Finally, further development according to the invention suggested that the sheet metal jacket on its lower end at least one around the sheet metal jacket circumferential bulge, preferably one Has outer bead.
