Description

Die Erfindung betrifft einen Schiebeverschluss für einen Metallschmelze enthaltenden Behälter, mit einem Gehäuserahmen, in dem eine feuerfeste Bodenplatte und eine an letztere mittels Federorganen abdichtend anpressbare, in einer Schiebereinheit angeordnete feuerfeste Schieberplatte enthalten ist, wobei die Schiebereinheit mittels eines Antriebsorganes hin- und herbewegbar ist.The invention relates to a slide closure for a molten metal containing container, with a housing frame in which a refractory Bottom plate and a sealable pressure element which can be pressed onto the latter by means of spring members contain refractory slide plate arranged in a slide unit is, the slide unit back and forth by means of a drive member is movable.

Ein bekannter Schiebeverschluss nach der Druckschrift DE-C2 25 23 928, der sich insbesondere für einen Konverter als Metallschmelze enthaltenden Behälter eignet, weist eine Schiebeverschlussbaueinheit auf, die mit bekannten feuerfesten Verschleissteilen, namentlich einer Schieber-, einer Bodenplatte und einer Auslaufhülse, vormontiert ist. Diese vormontierte Einheit wird mittels Augenschrauben und Führungsbolzen an einen am Abstich des Konverters angebrachten Rahmen befestigt. Bei diesem Anbau muss gewährleistet sein, dass die beim Verschluss vorstehende Bodenplatte in die Nut des vordersten Abstichsteins des Abstichkanals eingreift und durch den zwischen diese eingesetzten und nachfolgend aushärtenden Mörtel eine dichte Verbindung erzeugt wird, wodurch ein Auslaufen der Stahlschmelze zwischen dieser Bodenplatte und des zu dieser korrespondierenden Abstichsteins verhindert wird, ansonsten ein Auslaufen von flüssiger Metallschmelze zwischen diesen Feuerfestteilen zu einer Zerstörung der gesamten Schiebeverschlussbaueinheit führen könnte.A known sliding closure according to DE-C2 25 23 928, which contains itself as a molten metal especially for a converter Suitable container, has a slide lock assembly that with known refractory wear parts, namely a slide, one Base plate and an outlet sleeve, is pre-assembled. This pre-assembled The unit is attached to an am using eyebolts and guide bolts Tapping the converter attached frame attached. With this cultivation it must be ensured that the base plate protruding from the closure engages in the groove of the foremost tapping block of the tapping channel and through the one used between them and subsequently hardening Mortar creates a tight connection, causing leakage of the Steel melt between this base plate and the one corresponding to it Is prevented, otherwise leakage of liquid molten metal between these refractory parts to destruction the entire slide lock assembly could lead.

Bei diesem bekannten Schiebeverschluss müssen die Verschlussplatten regelmässig ausgewechselt werden, da diese einem relativ starken Verschleiss ausgesetzt sind. Ein solcher Wechsel ist jedoch mit einigem Arbeitsaufwand verbunden, da der Verschluss vom heissen Konverter weggenommen geöffnet, die Platten ersetzt und dieser folglich wieder an das Abstichloch des Konverters montiert werden muss. Beim Montieren ist - wie bereits oben erwähnt - sicherzustellen, dass die Verbindung zwischen der Bodenplatte und dein an dieser anschliessenden feuerfesten Abstichstein durch Einsetzen von Mörtel absolut dicht ist.With this known sliding closure, the closure plates be replaced regularly, as this is relatively heavy wear are exposed. However, such a change requires a lot of work connected, since the closure was removed from the hot converter opened, the plates replaced and this consequently back to the Tap hole of the converter must be installed. When assembling is - as mentioned above - ensure that the connection between the base plate and your subsequent refractory tapping block is absolutely tight by inserting mortar.

Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, einen Schiebeverschluss nach der eingangs beschriebenen Gattung zu schaffen, der im Wesentlichen in einem automatisierten Betrieb auf einfache Art und Weise vom Behälter wegnehmbar ist bzw. an diesen montiert werden kann, und bei dem die Dichtheit zwischen den Platten einerseits bzw. zwischen der Bodenplatte und dem an dieser anschliessenden Kopfteil andererseits vollauf gewährleistet ist. In contrast, the object of the present invention is to provide a To create a sliding closure according to the type described at the outset, which is essentially simple in an automated operation and can be removed from the container or mounted on it can, and in which the tightness between the plates on the one hand or between the bottom plate and the head part adjoining this, on the other hand is fully guaranteed.

Erfindungsgemäss ist die Aufgabe durch das Kennzeichen des Anspruchs 1 gelöst.According to the invention, the object is characterized by the characterizing part of claim 1 solved.

Mit diesem erfindungsgemässen Schiebeverschluss lassen sich die in diesem eingesetzten verschleissenden Feuerfestplatten auswechseln, ohne dass an dem heissen Behälter, insbesondere, wenn es sich um einen Konverter handelt, länger dauernde manuelle Arbeiten ausgeführt werden müssen. Bei der Anwendung von Schiebeverschlüssen an einem Konverter ist im weiteren zu berücksichtigen, dass die feuerfesten Platten eine Länge bis zu 600 Millimetern oder noch länger aufweisen, und sie daher kaum mehr von Hand ausgewechselt werden können. Auch dies ist beim Schiebeverschluss nach der Erfindung vortrefflich gelöst.With this sliding closure according to the invention, the sliding closure in this replace wear-resistant refractory plates without that on the hot container, especially if it is a converter longer manual work must be carried out. When using sliding locks on a converter furthermore to take into account that the refractory panels are up to a length to have 600 millimeters or even longer, and therefore hardly anymore can be replaced by hand. This is also the case with the sliding lock solved admirably according to the invention.
