Description

Die Erfindung geht aus von einem Schieberplatte für Schieberverschlüsse von metallurgischen Gefäßen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a slide plate for slide closures of metallurgical vessels according to the preamble of patent claim 1.

Es ist beispielsweise aus der DE-OS 32 23 181 eine Schieberplatte bekannt geworden, bei der die keramische Platte mörtelfrei mittels eines Metallbandes bandagiert ist, wobei die erforderliche enge Spannung mittels Spannkeilen aufgebracht wird. Die Anbringung der Platte im Plattenträger erfolgt danach durch Befestigung der Bandage auf dem Träger mittels geeigneter bekannter Mittel, bei denen es sich in allen Fällen um komplizierte bewegliche Elemente.From DE-OS 32 23 181, for example, a slide plate has become known in which the ceramic plate is bandaged mortar-free by means of a metal band, the necessary tight tension being applied by means of clamping wedges. The plate is then attached to the plate carrier by attaching the bandage to the carrier by means of suitable known means, which in all cases are complicated movable elements.

Es ist weiterhin aus der DE-OS 35 22 134 eine keramische Schieberplatte bekannt geworden, die an ihren Stirnseiten mit einer Abschrägung versehen ist und mittels keilförmiger Hilfsmittel in den Plattenträger eingespannt ist derart, daß ein mit einer Gegenschräge versehener Spannkeil mittels einer Spßannschraube gegen die Platte gedrückt wird. Die Befestigung der - im übrigen nicht in einen Rahmen eingemörtelten - Platte ist außerordentlich aufwendig.It is also known from DE-OS 35 22 134, a ceramic slide plate, which is provided on its end faces with a bevel and is clamped in the plate carrier by means of wedge-shaped aids such that a clamping wedge provided with a counter-bevel is pressed against the plate by means of a tension screw is pressed. The attachment of the plate - which is otherwise not mortared into a frame - is extremely complex.

Es sind schließlich aus den DE-OS 27 27 742, 28 21 839, 36 35 717 und 38 05 074 verschiedene Lösungen zum Einbau von in einen Rahmen eingemörtelten keramischen Platten in einen Plattenträger bekannt geworden. So dienen beispielsweise im Falle der DE 27 27 742, DE 28 21 839 und DE 36 35 717 aufwendige bewegliche Elemente zur Befestigung der Platte, während bei der in der DE-OS 34 20 810 beschriebenen Ausführungsform in die Platte eine oder mehrere zusätzliche Bohrungen zur Befestigung mittels eines oder mehrerer im Tragrahmen angeordneter Bolzen. Diese Lösung ist ebenfalls sehr aufwendig und erfordert eine hohe Maßhaltigkeit der Bolzen und Bohrungen, da sonst die Bolzen entweder nicht in die Bohrungen hinein passen oder ein zu hohes Spiel entsteht, was zur Verschiebung der Platte im Rahmen führen kann.Finally, there are from DE-OS 27 27 742, 28 21 839, 36 35 717 and 38 05 074 various solutions for installing ceramic plates mortared in a frame in a plate carrier have become known. For example, in the case of DE 27 27 742, DE 28 21 839 and DE 36 35 717, complex movable elements are used to fasten the plate, while in the embodiment described in DE-OS 34 20 810 one or more additional holes are provided in the plate Attachment by means of one or more bolts arranged in the support frame. This solution is also very complex and requires a high degree of dimensional accuracy of the bolts and holes, since otherwise the bolts either do not fit into the holes or there is too much play, which can lead to the plate being displaced in the frame.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung einer Schieberplatte der beschriebenen Art zugrunde, bei der die keramische, von einer Bandage umschlossene oder in einem Rahmen eingemörtelte Platte einfach, d.h. ohne bewegliche Befestigungsmittel und mörtelfrei in den Plattenträger eingebracht werden kann.The present invention has for its object to provide a slide plate of the type described, in which the ceramic plate enclosed by a bandage or mortared in a frame is simple, i.e. can be inserted into the plate carrier without moving fasteners and without mortar.

Diese Aufgabe wird mit einer Schieberplatte mit den im Patentanspruch 1 wiedergegebenen Merkmalen gelöst.This object is achieved with a slide plate with the features set out in claim 1.

Durch die Verwendung eines in der beschriebenen Weise auf mindestens einem Teilbereich seines Umfanges mit einer sich vom oberen bis zum unteren Rand verjüngenden Auskröpfung versehenen Rahmens ist die Möglichkeit geschaffen, die Platte durch einfaches Eindrücken in den Plattenträger mörtelfrei kraftschlüssig zu befestigen in der weise, daß sich der ausgekröpfte Teil des Rahmens beim Eindrücken verformt und auf diese Weise fest in dem Rahmen verklemmt. Die erfindungsgemäße Ausführung des Rahmens ist von besonderem Vorteil für solche Ausführungsformen einer Schieberplatte, bei denen die keramische Platte anstelle in einer einfachen Bandage in einem topfförmigen Rahmen gehalten ist. In diesen Fällen erstreckt sich die (keilförmige) Auskröpfung vom unteren Bodenrand bis zum oberen Rand der Seitenfläche. Die Wirkung kann durch die Anbringung einer nicht verformbaren Schiene aus abriebfestem Material noch verstärkt werden, die sich in dem der Auskröpfung gegenüberliegenden Bereich im wesentlichen wandparallel vom Boden bis zum oberen Rand erstreckt und unter deren Wirkung sich der ausgekröpfte Teil des Rahmens nach innen verformt und fest unter Verklemmung der gesamten Platte um die Schiene legt.Through the use of a frame provided in the manner described on at least a portion of its circumference with an offset tapering from the upper to the lower edge, the possibility is created to non-positively fasten the plate by simply pressing it into the plate carrier in such a way that the cranked part of the frame deformed when pressed in and thus firmly clamped in the frame. The design of the frame according to the invention is particularly advantageous for those embodiments of a slide plate in which the ceramic plate is held in a pot-shaped frame instead of in a simple bandage. In these cases, the (wedge-shaped) offset extends from the lower edge of the floor to the upper edge of the side surface. The effect can be further enhanced by attaching a non-deformable rail made of abrasion-resistant material, which extends essentially parallel to the wall from the floor to the upper edge in the area opposite the offset, and under the effect of which the cranked part of the frame deforms inwardly and firmly with the entire plate jammed around the rail.

In einer besonders vorteilhaften Ausführungsform ist das die Platte mit dem Rahmen verbindende Mörtelbett im Bereich der Auskröpfung ausgenommen und der zwischen Auskröpfung und Mörtel- bezw. Plattengrund gebildete Holraum zumindest teilweise mit einer Einlage aus einem plastisch oder elastisch verformbaren Material ausgefüllt ist. In diesem Falle besteht die Möglichkeit, die Schiene geringfügig hinterschnitten zu gestalten, ohne daß es zu einer Beschädigung des keramischen Körpers der Platte kommt, wobei die Auskröpfung aufgrund der - geringfügigen - Elastizität des Materials hinter die Schiene bezw. umgekehrt die Schiene über die - nach dem Eindrücken der Platte in den Plattenträger über den Rand des Rahmens greift und damit einen absolut festen Sitz der Platte in ihrem Träger gewährleistet.In a particularly advantageous embodiment, the mortar bed connecting the plate to the frame is excluded in the region of the offset and that between the offset and mortar or. Cavity formed plate base is at least partially filled with an insert made of a plastically or elastically deformable material. In this case, there is the possibility of making the rail slightly undercut without causing damage to the ceramic body of the plate, the offset being due to the - slight - elasticity of the material behind the rail. conversely, the rail over which - after pressing the plate into the plate carrier over the edge of the frame and thus ensures an absolutely firm fit of the plate in its carrier.

Im übrigen kann die Klemmschiene jede beliebige Form aufweisen, d.h. als Profil- oder Rundstqab ausgebildet sein.Otherwise, the clamping rail can have any shape, i.e. be designed as a profile or round bar.

Der in der Zeichnung wiedergegebene Schieberverschluß für ein metallurgisches Gefäß besteht aus der keramischen Platte 1, die mittels eines Bindemittels 2, vorzugsweise Zement, in einem Rahmen 3 gehalten und mit diesem mörtelfrei kraftschlüssig in einem Plattenträger 4 befestigt ist. Der Rahmen 3 ist - siehe Fig. 2 - auf dem dargestellten Teil in zwei Teilbereichen seines Umfanges mit einer Auskröpfung 5, 5a versehen, die nicht geradlinig verläuft sondern eine sich vom oberen Rand zum unteren Rand des Rahmens 3 keilförmig verjüngende Form aufweist. Der Plattenträger 3 ist in dem der Auskröpfung 5, 5a gegenüberliegenden Bereich mit einer sich vom Boden bis zum oberen Rand erstreckenden, im wesentlichen wandparallel verlaufenden Klemmschiene 6 aus nicht verformbaren und abriebfesten Material versehen, von denen in der Zeichnung zur besseren Verdeutlichung der Montage lediglich eine Schiene angedeutet ist.The slide closure shown in the drawing for a metallurgical vessel consists of the ceramic plate 1, which is held in a frame 3 by means of a binder 2, preferably cement, and is non-positively fastened in a plate carrier 4 with this mortar-free. The frame 3 - see FIG. 2 - is provided on the part shown in two partial areas of its circumference with an offset 5, 5a which does not run in a straight line but has a tapered shape from the upper edge to the lower edge of the frame 3. The plate carrier 3 is provided in the region opposite the offset 5, 5a with a clamping rail 6 which extends from the floor to the upper edge and runs essentially parallel to the wall and is made of non-deformable and abrasion-resistant material, only one of which is shown in the drawing to better illustrate the assembly Rail is indicated.

In der in der Zeichnung wiedergegebenen Ausführungsform ist die Platte 1 bezw. das sie in dem Rahmen haltende Mörtelbett im Bereich der Auskröpfung 5 ausgenommen und der zwischen Auskröpfung 5 und Mörtelbett 2 gebildete Hohlraum 7 mit einer Einlage 8 aus einem plastisch oder elastisch verform- sowie komprimierbaren Material ausgefüllt.In the embodiment shown in the drawing, the plate 1 is. the mortar bed holding it in the frame in the region of the offset 5 is excluded and the cavity 7 formed between the offset 5 and mortar bed 2 is filled with an insert 8 made of a plastically or elastically deformable and compressible material.

Vor dem Einbrigen der Platte in den Träger weisen die Auskröpfungen die in Fig. 2 der Zeichnung rechts oben oder in Fig. 3 wiedergebene Form auf, wobei die Einkröpfung 5 beim Eindrücken der Platte in den Plattenträger unter Verdrängung der komprimierbaren Einlage 8 zunächst elastisch, danach plastisch in die links oben wiedergegebene Form 5a verformt wird. Aufgrund dieser Elastizität drückt sich die Auskröpfung 5 nach der Verformung fest gegen die Klemmschiene 6 an, die gegebenenfalls auch eine geringfügig rückspringende Form aufweisen kann, so daß sie nach der Montage über den oberen Rand des Rahmens greift. Es ist auf diese Weise die sichere Halterung der Platte in ihrem Rahmen gewährleistet. Aus der vorstehenden DArstellung ergibt sich deutlich, daß die Montage ohne jede weitere Hilfmittel durch einfaches Eindrücken der Platte in den Plattenträger erfolgt, wobei alle unvermeidbaren Toleranzen ohne weiteres ausgeglichen werden.Before the plate is inserted into the carrier, the offsets have the shape shown at the top right in FIG. 2 of the drawing or in FIG. 3, the indentation 5 first being elastic when the plate is pressed into the plate carrier, displacing the compressible insert 8, and then is plastically deformed into the shape 5a shown at the top left. Because of this elasticity, the offset 5 presses firmly against the clamping rail 6 after the deformation, which may also have a slightly recessed shape, so that it engages over the upper edge of the frame after assembly. This ensures that the plate is held securely in its frame. From the above illustration it is clear that the assembly is carried out without any further aids by simply pressing the plate into the plate carrier, all the unavoidable tolerances being easily compensated for.
