Description

Die Erfindung betrifft eine Einspannvorrichtung für eine keramische Verschlußplatte in einem Tragrahmen oder einer Kassette eines Verschlusses, insbesondere eines Schieberverschlusses an einem metallurgischen Gefäß, mit einem zwischen der Verschlußplatte und dem Tragrahmen oder der Kassette angeordneten, die Verschlußplatte umgebenden und haltenden Band.The invention relates to a clamping device for a ceramic closure plate in a support frame or a cassette of a closure, in particular one Slider closure on a metallurgical vessel, with a between the Sealing plate and the support frame or the cassette arranged, the Closure plate surrounding and holding tape.

Eine derartige Einrichtung ist in der DE 34 21 205 C2 beschrieben. Dort ist ein Spannband verwendet, welches mittels einer am Tragrahmen befestigten Spanneinrichtung um die Verschlußplatte spannbar ist. An den Längsseiten der Verschlußplatte ist die Kraft, mit der das Spannband an die Verschlußplatte angedrückt wird, höchstens gering. Außerdem ist die Einrichtung aufwendig. Eine ähnliche Einrichtung ist auch in der DE 32 23 181 C2 beschrieben.Such a device is described in DE 34 21 205 C2. There is a Tension strap used, which is attached to the support frame by means of a Clamping device can be clamped around the closure plate. On the long sides the closure plate is the force with which the strap is attached to the closure plate is pressed, at most slightly. In addition, the setup is complex. A Similar device is also described in DE 32 23 181 C2.

Nach der DE 30 01 122 A1 ist die Verschlußplatte mittels einzelnen elastischen Profilstücken an dem Tragrahmen gehalten. Diese sind im zwischen der Verschlußplatte und dem Tragrahmen verlaufenden Spalt dort vorgesehen, wo dieser geradlinig verläuft; in gekrümmten Bereiches des Spaltes bzw. der Verschlußplatte ist die Verschlußplatte nicht eingespannt gehalten. Die Einspannung ist dabei auf den Umfang der Verschlußplatte bezogen ungleichmäßig. According to DE 30 01 122 A1, the closure plate is by means of individual elastic Profile pieces held on the support frame. These are in between the Closure plate and the support frame extending gap provided where this runs in a straight line; in the curved area of the gap or Closure plate, the closure plate is not clamped. The Clamping is uneven in relation to the circumference of the closure plate.

Außerdem ist es Stand der Technik, die Verschlußplatte in den Tragrahmen einzumörteln oder den Tragrahmen auf die Verschlußplatte aufzuschrumpfen. Beides ist mit einem beträchtlichen Aufwand verbunden und erschwert ein Austauschen der Verschlußplatte, beispielsweise bei der Reparatur. Beim Aufschrumpfen entsteht, ähnlich wie bei der Verwendung eines Spannbandes, nur eine ungleichmäßige Verteilung der Einspannkraft.In addition, it is state of the art, the closure plate in the support frame mortar or shrink the support frame onto the closure plate. Both involve considerable effort and make it more difficult Replacing the locking plate, for example during repairs. At the Shrinking occurs, similar to the use of a strap, only an uneven distribution of the clamping force.

Aufgabe der Erfindung ist es, eine Einspannvorrichtung vorzuschlagen, bei der die Verschlußplatte im wesentlichen an ihrem gesamten Umfang gleichmäßig eingespannt ist.The object of the invention is to propose a clamping device in which the closure plate is substantially uniform over its entire circumference is clamped.

Erfindungsgemäß ist obige Aufgabe dadurch gelöst, daß das Band in Längsrichtung gewellt ist, wobei der Verschlußplatte zugewandte Wellenhöcker federelastisch an dieser anliegen und dem Tragrahmen oder der Kassette zugewandte Wellenhöcker ebenfalls federelastisch an diesem oder dieser anliegen.According to the invention the above object is achieved in that the band in the longitudinal direction is corrugated, the closure plate facing wave hump on resilient these rest and the bumps facing the support frame or the cassette also resiliently rest against this or this.

Das Band erstreckt sich um den Umfang der Verschlußplatte. Seine Wellenhöcker drücken federelastisch wechselweise gegen die Verschlußplatte und gegen den Tragrahmen oder die Kassette. Dadurch ist die Verschlußplatte an ihrem gesamten Umfang gleichmäßig in den Tragrahmen oder die Kassette eingespannt. Etwaige Toleranzen der Verschlußplatte und des Tragrahmens bzw. der Kassette, werden durch die Federelastizität des gewellten Bandes ausgeglichen.The band extends around the circumference of the closure plate. His Wave bumps alternately press against the closure plate in a resilient manner and against the support frame or the cassette. This makes the locking plate along its entire circumference evenly in the support frame or the cassette clamped. Any tolerances of the locking plate and the support frame or the cassette, are due to the spring elasticity of the corrugated tape balanced.

In bevorzugter Ausgestaltung der Erfindung sind die an der Verschlußplatte anliegenden Wellenhöcker mit Abplattungen versehen, die flächig an der Verschlußplatte anliegen. Dadurch ist eine flächige Übertragung der Einspannkraft auf die keramische Verschlußplatte erreicht. Die Druckfestigkeit der Keramik der Verschlußplatte wird dadurch auch bei hohen Einspannkräften nicht überschritten, was der Fall sein könnte, wenn die Wellenhöcker die Verschlußplatte nur linienförmig berühren. In a preferred embodiment of the invention, they are on the closure plate adjacent wave humps with flats that are flat on the Fit the locking plate. This is a two-dimensional transfer of the Clamping force on the ceramic closing plate reached. The compressive strength The ceramic of the closure plate is thereby even with high clamping forces not exceeded, which could be the case if the wave bumps the Only touch the locking plate in a line.

Es ist auch möglich, die an dem Tragrahmen oder der Kassette anliegenden Wellenhöcker mit Abplattungen zu versehen, die flächig an dem Tragrahmen oder der Kassette anliegen. Vorzugsweise sind jedoch die dem Tragrahmen oder der Kassette zugewandten Wellenhöcker gerundet. Es ist dadurch möglich, am Band mehr Wellenhöcker anzuordnen, als wenn auch die dem Tragrahmen oder der Kassette zugewandten Wellenhöcker mit Abplattungen versehen wären. Dadurch wird die Einspannung verbessert.It is also possible to rest against the support frame or the cassette Wave bumps to be provided with flats, which are flat on the support frame or the cassette. However, the support frame is preferred or rounded wave bumps facing the cassette. It is possible to arrange more bumps on the belt than if also that of the supporting frame or the wave bumps facing the cassette would be provided with flattened portions. This improves the clamping.

Die Erfindung sieht ferner vor, daß das zwischen den Tragrahmen oder die Kassette und die Verschlußplatte eingesetzte gewellte Band gegenüber seinem freien Zustand gestaucht ist. Zum Stauchen des Bandes ist vorzugsweise zwischen den dem Tragrahmen oder der Kassette zugewandten Wellenhöckern und dem Tragrahmen oder der Kassette ein Zwischenblech angeordnet.The invention further provides that between the support frame or the Cassette and the shutter plate inserted corrugated tape opposite is compressed in its free state. To compress the tape preferably between the support frame or the cassette facing wave humps and the support frame or the cassette Intermediate plate arranged.

Zwischen einer keramischen Verschlußplatte 1 und einem diese aufnehmenden metallischen Tragrahmen 2 besteht ein umlaufender Spalt 3. Zum Einspannen der Verschlußplatte 1 im Tragrahmen 2 ist in den Spalt 3 ein gewelltes Band 4 aus hitzebeständigem Federstahl eingesetzt. Die Verschlußplatte 1 ist in üblicher Weise mit einer Durchflußöffnung 5 versehen. Der Tragrahmen 2 weist einen Eingriff 6 auf, an dem er zusammen mit der Verschlußplatte 1 zum Schließen oder Öffnen eines Schieberverschlusses eines metallurgischen Gefässes verschieblich ist.Between a ceramic closure plate 1 and one receiving metallic support frame 2 there is a circumferential gap 3rd To clamp the closure plate 1 in the support frame 2 is in the gap 3rd a corrugated band 4 made of heat-resistant spring steel is used. The Closure plate 1 is provided in the usual way with a flow opening 5. The support frame 2 has an engagement 6, on which it together with the Locking plate 1 for closing or opening a slide lock of a metallurgical vessel is displaceable.

Das in Längsrichtung gewellte Band 4 bildet Wellenhöcker 7, die an die Verschlußplatte 1 angedrückt sind und zwischen diesen jeweils Wellenhöcker 8, die sich über Zwischenbleche 9 in dem Tragrahmen 2 abstützen.The longitudinally corrugated band 4 forms wave bumps 7, which to the Closure plate 1 are pressed and between these respective bumps 8, which are supported by intermediate plates 9 in the support frame 2.

Bei der Ausführung nach Fig. 2 sind die Wellenhöcker 7 mit Abplattungen 10 versehen, die flächig an der Verschlußplatte 1 anlegen. Die dem Tragrahmen 2 zugewandten Wellenhöcker 8 sind gerundet.In the embodiment according to FIG. 2, the wave bumps 7 with flattenings 10 provided that lay flat on the closure plate 1. The support frame 2 facing wave bumps 8 are rounded.

Bei der Ausführung nach den Figuren 4 und 5 sind sowohl die Wellenhöcker 7 als auch die Wellenhöcker 8 gerundet. Dies hat den Vorteil, daß die Wellenhöcker sehr dicht beieinanderliegen können. Nachteilig ist jedoch insbesondere bei den Wellenhöckern 7, daß nur eine Linienberührung mit der Verschlußplatte 1 stattfindet, die, um Beschädigungen der Keramik der Verschlußplatte 1 zu vermeiden, eine entsprechend hohe Druckfestigkeit der Keramik voraussetzt.In the embodiment according to FIGS. 4 and 5, both the wave bumps 7 as well as the wave bumps 8 rounded. This has the advantage that the Wave bumps can be very close together. However, it is disadvantageous especially with the wave bumps 7 that only a line contact with the Closure plate 1 takes place to damage the ceramic Closure plate 1 to avoid a correspondingly high pressure resistance of the Ceramics are required.

Beim Ausführungsbeispiel nach Figur 6 sind sowohl die Wellenhöcker 7 als auch die Wellenhöcker 8 mit Abplattungen versehen.In the embodiment of Figure 6, both the wave bumps 7 and also the wave bumps 8 are provided with flattenings.

Die Ausführung nach Figur 2 hat den Vorteil, daß die Abplattungen 10 nur bei der Verschlußplatte 1 vorgesehen sind, also an deren Druckfestigkeit keine besonders hohen Anforderungen zu stellen sind, und durch die gerundeten Wellenhöcker 8 am Tragrahmen 2 dennoch eine dichte Abfolge der Wellenhöcker 7, 8 möglich ist. The embodiment according to FIG. 2 has the advantage that the flattenings 10 are only at the closure plate 1 are provided, that is, none of their compressive strength particularly high demands are to be made, and due to the rounded Wave hump 8 on the support frame 2 still a dense sequence of Wave bumps 7, 8 is possible.

Wellenhöcker 7 und Wellenhöcker 8 sind sowohl in den geradlinig verlaufenden Umfangsbereichen 11 als auch in den gekrümmt verlaufenden Umfangsbereichen 12 vorgesehen. Die Verschlußplatte 1 wird dadurch an ihrem gesamten Umfang gleichmäßig in den Tragrahmen 2 eingespannt. Die Zwischenbleche 9 sind sowohl in den geraden Umfangsbereichen 11 als auch in den gekrümmten Umfangsbereichen 12 vorgesehen. Anstelle von mehreren Zwischenblechen 9 läßt sich auch ein einzelnes Zwischenblech verwenden.Wave bumps 7 and wave bumps 8 are both in the straight line Circumferential areas 11 as well as in the curved ones Circumferential areas 12 are provided. The closure plate 1 is thereby their entire circumference clamped evenly in the support frame 2. The intermediate plates 9 are both in the straight peripheral regions 11 and also provided in the curved peripheral regions 12. Instead of A plurality of intermediate plates 9 can also be a single intermediate plate use.

Das gewellte Band 4 wird im entspannten Zustand, in dem die Wellenhöcker 7, 8 einen Abstand H (vgl. Fig. 4) haben, in den Spalt 3 eingelegt, wobei der Abstand H der Spaltbreite B etwa gleich ist. Anschließend werden die Zwischenbleche 9 zwischen die Wellenhöcker 8 und den Tragrahmen 2 in Richtung des Pfeiles E (vgl. Fig.3) eingepreßt. Um dies zu erleichtern, sind die Zwischenbleche 9 mit Schrägen 13 und der Tragrahmen 2 mit einer zugeordneten Schräge 14 versehen. Die Zwischenbleche weisen die Dicke d auf. Durch das Einpressen der Zwischenbleche 9 wird das gewellte Band 4 gestaucht, so daß der Abstand der Wellenhöcker 7, 8 h beträgt (vgl. Fig. 5), wobei H = h + d. Der Abstand H beträgt beispielsweise 5 mm und wird mit einem Zwischenblech der Dicke 2 mm auf 3 mm gestaucht. Durch das Stauchen übt das gewellte Band 4 die gewünschte Einspannkraft auf die Verschlußplatte 1 aus. Beispielsweise lassen sich mit einem gewellten Band, bei dem ein Wellenhöcker auf der Länge l, wobei l etwa 1 cm ist, auf die Verschlußplatte 1 eine Kraft von 100 kg/cm übertragen.The corrugated band 4 is inserted into the gap 3 in the relaxed state in which the wave bumps 7, 8 are at a distance H (see FIG. 4), the distance H being approximately equal to the gap width B. The intermediate plates 9 are then pressed in between the shaft bumps 8 and the support frame 2 in the direction of the arrow E (see FIG. 3). In order to facilitate this, the intermediate plates 9 are provided with bevels 13 and the support frame 2 with an associated bevel 14. The intermediate plates have the thickness d. By pressing the intermediate plates 9, the corrugated band 4 is compressed, so that the distance between the wave bumps is 7, 8 h (see. Fig. 5), wherein H = h + d . The distance H is 5 mm, for example, and is compressed to 3 mm with an intermediate plate 2 mm thick. By upsetting the corrugated band 4 exerts the desired clamping force on the closure plate 1. For example, a force of 100 kg / cm can be transmitted to the closure plate 1 with a corrugated band in which a wave hump of length l, where l is approximately 1 cm.

Um das Einlegen des gewellten Bandes in den Spalt 3 zu erleichtern, kann auch der Abstand H der Wellenhöcker 7, 8 in entspanntem Zustand um einen Betrag x kleiner als die Spaltbreite B bemessen sein. In diesem Falle ist H = h + d - x. Der Zwischenabstand x beträgt beispielsweise 3 mm, der Abstand H beträgt seinerseits 5 mm und wird mit einem Zwischenblech 9 der Dicke 5 mm auf 3 mm gestaucht.In order to facilitate the insertion of the corrugated band into the gap 3, the distance H of the wave bumps 7, 8 can also be dimensioned in the relaxed state by an amount x smaller than the gap width B. In this case it is H = h + d - x . The intermediate distance x is, for example, 3 mm, the distance H is in turn 5 mm and is compressed to 3 mm with an intermediate plate 9 with a thickness of 5 mm.

Normale Toleranzen der Verschlußplatte 1 und des Tragrahmens 2 werden durch die Federelastizität des Bandes 4 kompensiert. Besonders große Maßabweichungen zwischen der Verschlußplatte und dem Tragrahmen werden durch Verwendung von unterschiedlich starken Zwischenblechen 9 ausgeglichen. Normal tolerances of the closure plate 1 and the support frame 2 are by the spring elasticity of the band 4 is compensated. Particularly large dimensional deviations between the closure plate and the support frame are by using different thickness intermediate plates 9 balanced.

Ist eine Demontage der Verschlußplatte 1 erforderlich, wird diese zweckmäßigerweise hydraulisch aus dem Tragrahmen 2 herausgedrückt.If disassembly of the closure plate 1 is required, this will expediently pressed out hydraulically from the support frame 2.

Die gleiche Einspannvorrichtung ist auch ohne weiteres zum Einspannen der Verschlußplatte 1 in eine metallische Kassette verwendbar. Diese unterscheidet sich bekanntlich vom Tragrahmen 2 im wesentlichen nur dadurch, daß sie den Eingriff 6 nicht aufweist. Die Kassette mit der darin eingespannten Verschlußplatte 1 ist in bekannter Weise in den Tragrahmen 2 einlegbar oder an diesen angelenkt.The same clamping device is also easy to clamp the Locking plate 1 can be used in a metallic cassette. This differs as is well known from the support frame 2 essentially only in that it engages the 6th does not have. The cassette with the locking plate 1 clamped therein is in known manner in the support frame 2 insertable or hinged to this.
