Description

Vorrichtung zur Seitenabdichtung einer Gießanlage  Device for side sealing of a casting plant
Gebiet der Erfindung Field of the invention
Die vorliegende Erfindung ist auf eine Vorrichtung zur Seitenabdichtung, insbesondere, aber nicht ausschließlich, zur Schmalseitenabdichtung in Bandoder Stranggießanlagen gerichtet. The present invention is directed to an apparatus for side sealing, particularly, but not exclusively, for narrow side sealing in belt or continuous casters.
Stand der Technik State of the art
Aus dem Stand der Technik sind diverse Systeme zur Seitenabdichtung von Band- oder Stranggießanlagen bekannt. Aufgabe dieser Systeme ist es im Wesentlichen, das Auslaufen von flüssigem Metall, insbesondere Stahl zu den Seiten der Anlage zu verhindern. Ferner werden diese Systeme unter anderem zur Justierung der Breite bzw. der Dicke der gegossenen Metallbänder oder - stränge verwendet. Various systems for side sealing of strip or continuous casting plants are known from the prior art. The object of these systems is essentially to prevent the leakage of liquid metal, especially steel to the sides of the system. Furthermore, these systems are used, inter alia, for adjusting the width or the thickness of the cast metal strips or strands.
Die Veröffentlichung EP 0 145 81 1 A1 offenbart eine Gießanlage mit beweglichen Seitendämmen. Diese Seitendämme bestehen aus einzelnen, auf einem Band aufgereihten Blöcken. Durch eine neben den Blöcken verlaufende Einrichtung können die Blöcke auf der dem gegossenen Band abgewandten Seiten mit Wasser besprüht werden. Solche kettenartigen Seitendämme können zwar relativ robust ausgebildet werden, haben jedoch den Nachteil, dass deren Blöcke nicht immer hinreichend gekühlt werden können oder große Mengen Wasser benötigt werden, die gegebenenfalls wiederum separat abgeführt werden müssen. The publication EP 0 145 81 1 A1 discloses a caster with movable side dams. These side dams consist of individual blocks lined up on a band. By means of a device running alongside the blocks, the blocks can be sprayed with water on the sides facing away from the cast strip. Although such chain-like side dams can be relative robust, but have the disadvantage that their blocks can not always be sufficiently cooled or large amounts of water are needed, which in turn may need to be removed separately.
Der Artikel "Direct Strip Casting (DSC) - an Option for the Production of New Steel Grades" aus der Zeitschrift "Steel research", 74 aus dem Jahr 2003, Nr. 1 1/12, offenbart eine horizontale Bandgießanlage, welche ein System zur seitlichen Abdichtung eines Bands umfasst, welches ebenfalls Ketten aus Kupferblöcken nutzt. Einzelne Kupferblöcke der Kette werden dabei durch Schlauchverbindungen untereinander verbunden. An den Enden der Schlauchverbindungen befinden sich metallische Gewinde, welche in die Kupferblöcke einschraubbar sind. Dieses System erlaubt zwar ein verbesserte Kühlung der Kupferblöcke, weist jedoch einige entscheidende Nachteile auf: Die Verbindungsschläuche mit Gewebeeinlage nehmen alle Zugkräfte in der Kette auf und können auf Dauer nicht der Beanspruchung unter Produktionsbedingungen standhalten. Bei intensiver Beanspruchung können die Schläuche brechen oder gar zerreißen, was zu einer Gefährdung der Betriebssicherheit führen kann, wenn zum Beispiel flüssiger Stahl nicht mehr abgehalten werden kann. Ferner kann zum einen die Qualität des Bandes negativ durch unkontrolliert ausströmendes Wasser beeinflusst werden und zum anderen die Kühlung der Kette nicht mehr sichergestellt werden. Ein weiterer Nachteil dieses Systems besteht darin, dass bei langen Kühlketten oder Gießprozessen mit hohem Kühlungsbedarf, der Druck des Kühlwassers über die Länge der Kette nicht ausreichend ist, wodurch die Kühlung für Teile der Kette nicht mehr hinreichend gewährleistet werden kann. Eine Erhöhung des Wasserdrucks in der Kette ist nur begrenzt möglich, denn diese wirkt sich negativ auf die Schließkraft der Kette in deren Längsrichtung aus. Ein weiterer Nachteil der Vorrichtung besteht darin, dass Ketten zur Seitenabdichtung, wie ebenfalls in der Veröffentlichung gezeigt, oft über Kettenräder umgelenkt werden, um sich umlaufend mit dem gegossenen Band zu bewegen. Gerade aber im Bereich der Kettenräder wirken auf die Schläuche, insbesondere am Übergang zu einem metallischen Gewinde erhöhte Biegekräfte, so dass sich dort Risse und/oder Bruchstellen bilden können. Schließlich sind die Montage und die Fertigung der gewebeverstärkten Schläuche zeitaufwendig. The article "Direct Strip Casting (DSC) - Option for the Production of New Steel Grades" from the journal "Steel research", 74 from the year 2003, No. 1 1/12, discloses a horizontal strip caster, which is a system for the lateral sealing of a band, which also uses chains of copper blocks. Individual copper blocks of the chain are thereby connected to each other by hose connections. At the ends of the hose connections are metallic threads which can be screwed into the copper blocks. Although this system allows for improved cooling of the copper blocks, it does have some key drawbacks: the fabric-lined interconnect hoses absorb all of the tensile forces in the chain and can not withstand long-term stress under production conditions. During intensive use, the hoses may break or even rupture, which can endanger the operational safety if, for example, liquid steel can no longer be prevented. Furthermore, on the one hand the quality of the band can be negatively influenced by uncontrolled outflowing water and on the other hand the cooling of the chain can no longer be ensured. Another disadvantage of this system is that in long cold chains or casting processes with high cooling demand, the pressure of the cooling water over the length of the chain is not sufficient, whereby the cooling for parts of the chain can not be adequately ensured. An increase in the water pressure in the chain is limited, because this has a negative effect on the closing force of the chain in the longitudinal direction. Another disadvantage of the device is that chains for side sealing, as also shown in the publication, are often deflected by sprockets to move circumferentially with the cast strip. But especially in the field of sprockets act on the tubes, especially at the transition to a metallic thread increased bending forces, so that there cracks and / or breakages can form. Finally, the assembly and manufacture of the fabric reinforced hoses are time consuming.
Offenbarung der Erfindung Disclosure of the invention
Ziel der vorliegenden Erfindung ist es, mindestens einen der obengenannten Nachteile zu überwinden. Insbesondere soll eine Vorrichtung zur (mitlaufenden) seitlichen Abdichtung einer Bandgießanlage zum Gießen eines Metallbands oder - Strangs bereitgestellt werden, welche robuster und/oder einfacher zu fertigen ist als die bekannten Systeme und gleichzeitig eine gute Kühlung der Kettenglieder erlaubt. The aim of the present invention is to overcome at least one of the above-mentioned disadvantages. In particular, a device for (side-by-side) lateral sealing of a strip casting plant for casting a metal strip or strand is to be provided, which is more robust and / or easier to manufacture than the known systems and at the same time allows good cooling of the chain links.

Ferner ermöglicht das System eine Erhöhung des Wasserdrucks in der Leitung gegenüber einem System aus flexiblen Schläuchen. Zudem bleibt auch bei hohen Drücken die Beweglichkeit der Kette gewährleistet.

Thus, both a high reliability and a high quality of the strand or the band can be ensured. Furthermore, the system allows an increase in the water pressure in the line compared to a system of flexible hoses. In addition, the mobility of the chain is ensured even at high pressures.
Erfindungsgemäß kann unter dem Begriff der seitlichen Abdichtung sowohl eine Abdichtung der Schmal- als auch der Breitseiten eines Bandes oder Strangs bzw. auch die Abdichtung der Ober- und/oder Unterseiten eines solchen verstanden werden. Ferner kann die Vorrichtung sowohl in Senkrecht-Gießanlagen als auch in horizontalen Gießanlagen Verwendung finden. According to the invention, the term lateral seal can be understood as meaning both a sealing of the narrow and broad sides of a band or strand or also the sealing of the upper and / or lower sides of such. Furthermore, the device can be used both in vertical casting plants as well as in horizontal casting plants.

Insbesondere können die Verbindungsteile 5 im Wesentlichen die Form eines Rohrs aufweisen, dessen Querschnitt sowohl rund als auch eckig ausgebildet sein kann oder aber auch je nach Anwendung gänzlich andere Querschnitte besitzen kann. Das Verbindungsteil 5 ist durch Kugelgelenke mit den angrenzenden Blöcken 3 verbunden. In der dargestellten Form umfassen die Verbindungsteile 5 an ihren (den Metallblöcken 3 zugewandten) Enden jeweils einen Kugelgelenkkopf 9, wobei der Kanal 7 bevorzugt auch durch diesen Kopf 9 bzw. durch das Rohr verläuft. Ferner umfasst das Kugelgelenk im Allgemeinen eine Gelenkpfanne 1 1 bzw. eine Gelenkschale 1 1 , in der der Gelenkkopf 9 drehbar lagerbar ist. Insbesondere können das Rohr, der Gelenkkopf 9 und die Schale bzw. Pfanne 1 1 das Verbindungsteil 5 bilden. Alternativ ist es generell auch möglich, dass die Schale oder Pfanne 1 1 auch fest oder lösbar in den Metallblöcken 3 vorgesehen wird. Figure 1 shows a portion of a chain 1 of an embodiment of the invention for side sealing a strip or continuous casting, comprising a plurality of links or metal blocks 3. The blocks 3, which can also be referred to as dam blocks 3, are interconnected by connecting parts (or pieces or Through the chain 1 extends a coolant channel 7. This channel 7 extends preferably both through the blocks 3 and through the connecting parts 5. Within blocks 3, the channel can be expanded like a chamber for better cooling. Further, cooling fins may be provided within the blocks 3 for better heat exchange with the coolant. In particular, the connecting parts 5 may substantially have the shape of a tube, whose cross section may be formed both round and square or depending on the application may have completely different cross sections. The connecting part 5 is connected by ball joints with the adjacent blocks 3. In the illustrated form, the connecting parts 5 at their (the metal blocks 3 facing) ends each comprise a ball joint head 9, wherein the channel 7 preferably extends through this head 9 and through the tube. Furthermore, the ball joint generally comprises a joint socket 1 1 or a joint shell 1 1, in which the joint head 9 is rotatably storable. In particular, the tube, the condyle 9 and the shell or pan 1 1 can form the connecting part 5. Alternatively, it is generally possible that the Shell or pan 1 1 is provided fixed or detachable in the metal blocks 3.
Figur 2 zeigt eine vergrößerte Ansicht einer Verbindungstelle zwischen zwei Blöcken 3, wie sie bereits in Figur 1 dargestellt ist. Das Verbindungsteil 5 verbindet zwei aneinander angrenzende Metallblöcke 3. Durch die Metallblöcke 3 und das Verbindungsteil 5 verläuft der mit Kühlwasser befüllbare Kanal 7. Die Metallblöcke 3 sind bevorzugt derart ausgebildet, dass sie die Kugelgelenkschalen 1 1 formschlüssig aufnehmen. Zugkräfte, die entlang der Kette 1 wirken, können die Blöcke 3 bereits daher nicht voneinander separieren. Weitere Vorrichtungen zur Aufnahme von Zug- und/oder Druckkräften oder zur Abdichtung zwischen angrenzenden Blöcken 3 können zusätzlich vorgesehen werden. Figur 2 zeigt zudem eine bevorzugte Ausführungsform, gemäß der die Verbindungsteile 5 zweiteilig zum Separieren in Längsrichtung ausgebildet sind. Die Möglichkeit, das Verbindungsteil 5 bzw. das Rohr zwischen den Kugelgelenken bzw. den Metallblöcken 3 teilen zu können, erleichtert einen Austausch einzelner Glieder der Kette 1 bzw. den Austausch einzelner Kugelgelenke. Bevorzugt können auch die Metallblöcke 3 derart mehrteilig ausgebildet werden, dass diese zu öffnen sind und so Verbindungsteile 5 samt Lager bzw. Pfanne 1 1 zu entnehmen sind. Die Gelenkpfannen bzw. -schalen 1 1 sind bevorzugt gegenüber den Blöcken 3 und/oder den Gelenkköpfen 9 durch Dichtungen abgedichtet. Figure 2 shows an enlarged view of a junction between two blocks 3, as already shown in Figure 1. The connecting part 5 connects two adjoining metal blocks 3. Through the metal blocks 3 and the connecting part 5 of the fillable with cooling water channel 7. The metal blocks 3 are preferably designed such that they receive the ball joint cups 1 1 positively. Tensile forces acting along the chain 1, the blocks 3 therefore already can not separate from each other. Other devices for receiving tensile and / or compressive forces or for sealing between adjacent blocks 3 can be additionally provided. Figure 2 also shows a preferred embodiment, according to which the connecting parts 5 are formed in two parts for separating in the longitudinal direction. The ability to share the connecting part 5 or the tube between the ball joints or the metal blocks 3, facilitates replacement of individual links of the chain 1 and the replacement of individual ball joints. Preferably, the metal blocks 3 can be formed in such a multi-part, that they are open and so connecting parts 5 together with bearing or pan 1 1 can be seen. The joint sockets or shells 1 1 are preferably sealed relative to the blocks 3 and / or the rod ends 9 by seals.
Figur 3 zeigt ein erfindungsgemäßes Ausführungsbeispiel eines Verbindungsteils. Das Verbindungsteil ist im Wesentlichen durch ein Rohr gebildet, welches zwei ineinandersteckbare Rohrabschnitte umfasst. An den Enden des Rohrs umfasst das Verbindungsteil 5 jeweils eine Kugelgelenkform. Die dargestellte Form des Kugelgelenkkopfes 9 stellt lediglich ein Beispiel dar. Der Begriff Kugelgelenk soll im Rahmen der vorliegenden Anmeldung sich sowohl auf teil- bzw. halbkugelförmige Formen als auch auf Formen richten, die eine vollständige Kugel bilden. Der Kühlwasserkanal 7 verläuft jedoch bevorzugt durch den Gelenkkopf 9 hindurch. Auch die abgebildete Kugelgelenkpfanne 1 1 kann einen größeren/oder kleineren Bereich eines Gelenkkopfes 9 umfassen bzw. abdecken als dargestellt. Bevorzugt sind die Metallblöcke 3 aber nur um weniger als 15°, vorzugsweise weniger als 10° gegeneinander zu neigen. Gelenkköpfe 9 und -pfannen 1 1 können den maximal benötigten Neigewinkeln entsprechend ausgebildet werden. Wenn das Verbindungsteil 5 entlang seiner Achse teilbar ausgebildet ist, können bei Bedarf die beiden Teile des Verbindungsteils in Richtung seiner Längsachse getrennt werden, sodass einer der beiden Teile samt Gelenkschale 1 1 ausgetauscht werden kann oder nur eine Gelenkschale 1 1 ersetzt werden kann oder aber auch einer der Teile samt Kugelkopf 9 ausgetauscht werden kann. Figure 3 shows an inventive embodiment of a connecting part. The connecting part is essentially formed by a tube which comprises two telescoping pipe sections. At the ends of the tube, the connecting part 5 each has a ball joint shape. The illustrated shape of the ball joint head 9 is merely an example. In the context of the present application, the term ball joint is intended to be directed both to partially or hemispherical forms and to forms which form a complete sphere form. However, the cooling water channel 7 preferably passes through the condyle 9. Also, the illustrated ball joint socket 1 1 may include a larger or smaller area of a condyle 9 or cover as shown. Preferably, however, the metal blocks 3 are only inclined by less than 15 °, preferably less than 10 °, relative to one another. Rod ends 9 and pans 1 1 can be formed according to the maximum required tilt angles. If the connecting part 5 is formed divisible along its axis, if necessary, the two parts of the connecting part can be separated in the direction of its longitudinal axis, so that one of the two parts together with the joint shell 1 1 can be replaced or only one joint shell 1 1 can be replaced or even one of the parts including ball head 9 can be replaced.
Figur 4 zeigt das Verbindungsteil gemäß Figur 3, bei dem die beiden Gelenkpfannen 1 1 um einige Grad geneigt sind. Eine solche Situation kann zum Beispiel auftreten, wenn eine Kette 1 samt den an das Verbindungsteil 5 angrenzenden Metallblöcken 3 über ein Kettenrad oder einen ähnlichen Mechanismus umgelenkt wird. FIG. 4 shows the connecting part according to FIG. 3, in which the two joint sockets 11 are inclined by a few degrees. Such a situation may occur, for example, when a chain 1 together with the metal blocks 3 adjoining the connecting part 5 are deflected by means of a sprocket or a similar mechanism.
