Definitions
- the invention relates to a clamping device for a ceramic closure plate in a support frame or a cassette of a closure, in particular a slide closure on a metallurgical vessel, with a band arranged between the closure plate and the support frame or the cassette, surrounding and holding the closure plate.
- the closure plate is held on the support frame by means of individual elastic profile pieces. These are provided in the gap between the closure plate and the support frame where it runs in a straight line; in the curved area of the gap or the closure plate, the closure plate is not clamped. The clamping is uneven in relation to the circumference of the closure plate.
- the object of the invention is to propose a clamping device in which the closure plate is clamped substantially uniformly over its entire circumference.
- the above object is achieved in that the band is corrugated in the longitudinal direction, the one wave hump resiliently resting on the closure plate and the wave hump lying between them resiliently resting on the support frame or on the cassette.
- the band extends around the circumference of the closure plate. Its wave humps alternately press against the locking plate and against the supporting frame or the cassette. As a result, the closure plate is clamped uniformly over its entire circumference in the support frame or the cassette. Any tolerances of the closure plate and the support frame or the cassette are compensated for by the spring elasticity of the corrugated band.
- the wave bumps resting on the closure plate are provided with flattenings which lie flat against the closure plate. A flat transmission of the clamping force to the ceramic closure plate is thereby achieved. The pressure resistance of the ceramic of the closure plate is therefore not exceeded even with high clamping forces, which could be the case if the wave bumps only touch the closure plate in a linear manner.
- the wave bumps resting on the support frame or the cassette are provided with flats which lie flat against the support frame or the cassette.
- the wave bumps facing the support frame or the cassette are preferably rounded. This makes it possible to arrange more wave bumps on the belt than if the wave bumps facing the support frame or the cassette were also provided with flattened portions. This improves the clamping.
- the invention further provides that the corrugated tape inserted between the support frame or the cassette and the closure plate is compressed in relation to its free state.
- an intermediate plate is preferably arranged between the shaft bumps facing the support frame or the cassette and the support frame or the cassette.
- a corrugated band 4 made of heat-resistant spring steel is inserted into the gap 3.
- 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 can be moved together with the closure plate 1 for closing or opening a slide closure of a metallurgical vessel.
- the longitudinally corrugated band 4 forms wave bumps 7, which are pressed against the closure plate 1 and between these each wave bumps 8, which are supported by intermediate plates 9 in the support frame 2.
- the wave bumps 7 are provided with flattenings 10, which bear flat against the closure plate 1.
- the wave bumps 8 facing the support frame 2 are rounded.
- both the wave bumps 7 and the wave bumps 8 are rounded. This has the advantage that the wave bumps can be very close together. However, it is disadvantageous in particular in the case of the wave bumps 7 that only a line contact with the closure plate 1 takes place, which, in order to avoid damage to the ceramic of the closure plate 1, requires a correspondingly high compressive strength of the ceramic.
- both the wave bumps 7 and the wave bumps 8 are provided with flattened portions.
- the embodiment according to FIG. 2 has the advantage that the flattenings 10 are only provided for the closure plate 1, that is to say that their pressure resistance does not have to be particularly high, and due to the rounded wave bumps 8 on the supporting frame 2, a tight sequence of the wave bumps 7, 8 is possible.
- Wave bumps 7 and wave bumps 8 are provided both in the rectilinear circumferential regions 11 and in the curved circumferential regions 12.
- the closure plate 1 is thereby clamped evenly over the entire circumference in the support frame 2.
- the intermediate plates 9 are provided both in the straight peripheral regions 11 and in the curved peripheral regions 12. Instead of several intermediate plates 9, a single intermediate plate can also be used.
- 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 (cf. 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).
- 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.
- 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.
- 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 I, where I is approximately 1 cm.
- 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.
- closure plate 1 If disassembly of the closure plate 1 is required, it is expediently pressed hydraulically out of the support frame 2.
- the same clamping device can also be used without difficulty for clamping the closure plate 1 in a metallic cassette. As is known, this differs from the supporting frame 2 essentially only in that it does not have the engagement 6.
- the cassette with the locking plate 1 clamped therein can be inserted in a known manner into the support frame 2 or articulated thereon.

Abstract
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 a slide closure on a metallurgical vessel, with a band arranged between the closure plate and the support frame or the cassette, surrounding and holding the closure plate.
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 a tensioning strap is used, which can be tensioned around the closure plate by means of a tensioning device attached to the supporting frame. On the long sides of the closure plate, the force with which the tension band is pressed against the closure plate is at most low. 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 held on the support frame by means of individual elastic profile pieces. These are provided in the gap between the closure plate and the support frame where it runs in a straight line; in the curved area of the gap or the 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 to mortar the closure plate in the support frame or to shrink the support frame onto the closure plate. Both are associated with considerable effort and make it difficult to replace the closure plate, for example for repairs. When shrinking on, similar to the use of a tensioning strap, there is 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 clamped substantially uniformly over its entire circumference.
Erfindungsgemäß ist obige Aufgabe dadurch gelöst, daß das Band in Längsrichtung gewellt ist, wobei die einen Wellenhöcker federelastisch an der Verschlußplatte und zwischen diesen liegende Wellenhöcker federelastisch am Tragrahmen oder an der Kassette anliegen.According to the invention, the above object is achieved in that the band is corrugated in the longitudinal direction, the one wave hump resiliently resting on the closure plate and the wave hump lying between them resiliently resting on the support frame or on the cassette.
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. Its wave humps alternately press against the locking plate and against the supporting frame or the cassette. As a result, the closure plate is clamped uniformly over its entire circumference in the support frame or the cassette. Any tolerances of the closure plate and the support frame or the cassette are compensated for by the spring elasticity of the corrugated band.
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, the wave bumps resting on the closure plate are provided with flattenings which lie flat against the closure plate. A flat transmission of the clamping force to the ceramic closure plate is thereby achieved. The pressure resistance of the ceramic of the closure plate is therefore not exceeded even with high clamping forces, which could be the case if the wave bumps only touch the closure plate in a linear manner.
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 provide the wave bumps resting on the support frame or the cassette with flats which lie flat against the support frame or the cassette. However, the wave bumps facing the support frame or the cassette are preferably rounded. This makes it possible to arrange more wave bumps on the belt than if the wave bumps facing the support frame or the cassette were also 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 the corrugated tape inserted between the support frame or the cassette and the closure plate is compressed in relation to its free state. To compress the band, an intermediate plate is preferably arranged between the shaft bumps facing the support frame or the cassette and the support frame or the cassette.

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.There is a
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
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
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
Beim Ausführungsbeispiel nach Figur 6 sind sowohl die Wellenhöcker 7 als auch die Wellenhöcker 8 mit Abplattungen versehen.In the exemplary embodiment according to FIG. 6, both the
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
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
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
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
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

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.
