Description

Die Erfindung betrifft eine Stranggießeinrichtung, insbesondere zum Stranggießen von Stahl, mit einer Kokillen-Stützeinrichtung und einer gegenüber dieser oszillierend gelagerten Kokille, wobei die Kokille an der Kokillen-Stützeinrichtung über sich etwa quer zur Oszillationsrichtung erstreckende und Kräfte im elastischen Bereich aufnehmende Führungselemente abgestützt ist, wobei die Führungselemente etwa parallel zueinander und in Oszillationsrichtung im Abstand übereinander angeordnet sind, wobei die Führungselemente etwa parallel zueinander und in Oszillationsrichtung im Abstand übereinander angeordnet sind und wobei jedes Führungselement einerseits an der Kokillen-Stützeinrichtung und andererseits an der Kokille befestigt ist.The invention relates to a continuous casting device, in particular for the continuous casting of steel, with a mold support device and an oscillating one with respect to this Chill, the chill on the chill support about about across Extending the direction of oscillation and absorbing forces in the elastic range Guide elements is supported, the guide elements approximately parallel to each other and in Oscillation direction are arranged one above the other at a distance, the Guide elements approximately parallel to each other and at a distance in the direction of oscillation are arranged one above the other and each guide element on the one hand on the mold support device and on the other hand is attached to the mold.

Eine Stranggießeinrichtung dieser Art ist aus der DE-A- 2 248 066 bekannt. Die Kokille ist bei dieser Stranggießeinrichtung über zwei parallel zu einander und übereinander angeordnete Federpakete, die von Bandfedern gebildet sind, seitlich geführt. Die Oszillation wird durch einen Hydraulikzylinder bewerkstelligt, der einerseits am Stützgerilst und andererseits an einer Konsole der Kokille angreift. Die beiden Federpakete, die jeweils an einer Kokillenseite angeordnet sind und einerseits am Stützgerüst und anderseits an der Kokille fest eingespannt sind, haben hierbei die Führungskräfte aufzunehmen, d.h. sie werden auf Zug oder Druck belastet. Sie müssen wegen der Druckbelastung auf Knickung dimensioniert werden, wodurch sich eine große Dicke der Federpakete ergibt, und zwar eine weit größere Dicke als für die maximal auftretenden Zugkräfte erforderlich ist.A continuous caster of this type is known from DE-A-2 248 066. The mold is in this continuous caster via two parallel and one above the other Spring assemblies, which are formed by band springs, guided laterally. The oscillation is through accomplished a hydraulic cylinder that on the one hand on the support frame and on the other a console attacks the mold. The two spring packs, each on one side of the mold are arranged and firmly clamped on the one hand on the scaffolding and on the other hand on the mold managers have to be included, i.e. they are on train or push loaded. They have to be dimensioned because of the pressure load on buckling, which means there is a large thickness of the spring assemblies, namely a much greater thickness than for the maximum occurring tensile forces is required.

Um hierbei die Biegebeanspruchungen im zulässigen Bereich zu halten ist es erforderlich, die Federpakete entsprechend lang zu dimensionieren. Durch die große Dicke der Federpakete ergeben sich höhere Antriebskräfte, d.h. der Oszillationsantrieb muß entsprechend stärker bemessen werden. Nachteilig ist bei dieser bekannten Konstruktion weiters, daß die Lebenserwartung der Federpakete durch die hohe Biege-Wechselbeanspruchung, die sich aufgrund der großen Dicke ergibt, vermindert ist und daß zudem, um die Biege-Wechselbeanspruchung in einem zulässigen Rahmen zu halten, ein erhöhter Platzbedarf infolge der großen Baulänge der Federpakete erforderlich ist. Hierdurch leidet jedoch die Führungsgenauigkeit der Kokille, zumal durch die längeren Federpakete ein größeres elastisches Verhalten bewirkt wird, wodurch sich wiederum größere Auslenkungen und Abweichungen der Kokille von der gewünschten Führungsbahn ergeben. Weiters machen sich thermische Einflüsse bei längeren Federpaketen verstärkt bemerkbar, und zwar durch Abweichungen der Kokille von der gewünschten Führungsbahn. In order to keep the bending stresses within the permissible range, the Dimension spring assemblies accordingly long. Due to the large thickness of the spring assemblies there are higher driving forces, i.e. the oscillation drive must be correspondingly stronger be measured. Another disadvantage of this known construction is that the Life expectancy of the spring assemblies due to the high alternating bending stress, which is due to the large thickness, is reduced and also to the bending alternating stress to keep within a permissible framework, an increased space requirement is required due to the large length of the spring assemblies. However, this suffers Guiding accuracy of the mold, especially because of the longer spring assemblies a larger one elastic behavior is caused, which in turn causes larger deflections and Deviations of the mold from the desired guideway result. Furthermore make yourself Thermal influences are noticeable with longer spring assemblies, namely through Deviations of the mold from the desired guideway.

Aus der EP-A- 150 357 ist eine Strangführung für eine Stranggießkokille bekannt, bei der die Führung der Kokille mittels einer Blattfeder bewerkstelligt ist, die beiderends in einem Federträger brückenartig eingespannt ist und wobei mittig der Blattfeder die Kokille an der Blattfeder angreift. Eine solche Führungseinrichtung bedingt einen sehr großen Platzbedarf in Richtung der Blattfedernachse. Somit kann eine solche Führung nur dort vorgesehen werden, wo seitlich der Kokille genügend Platz vorhanden ist. Dies ist in der Regel bei Bloom- bzw. Knüppelanlagen nicht der Fall, so daß von dieser Führungsart für solche Anlagen kein Gebrauch gemacht werden kann.From EP-A-150 357 a strand guide for a continuous casting mold is known, in which the The mold is guided by means of a leaf spring, both ends in one Spring carrier is clamped in a bridge-like manner and with the leaf spring centering on the mold Leaf spring attacks. Such a guide device requires a very large amount of space in Direction of the leaf spring axis. Such a guidance can therefore only be provided there where there is enough space on the side of the mold. This is usually with Bloom or Stick systems are not the case, so none of this type of guidance for such systems Can be used.

Die Erfindung bezweckt die Vermeidung dieser Nachteile und Schwierigkeiten und stellt sich die Aufgabe, eine Stranggießeinrichtung der eingangs beschriebenen Art zu schaffen, die neben einer hohen Führungsgenauigkeit für die Kokille nur einen geringen Platzbedarf und geringe Antriebskräfte für den Oszillationsantrieb erfordert. Insbesondere soll der Platzbedarf so gering sein, daß eine Anwendung für Bloom- und Knüppelanlagen in einfacher Weise möglich ist.The invention aims at avoiding these disadvantages and difficulties and presents itself the task of creating a continuous caster of the type described above, the in addition to high guidance accuracy for the mold, only a small space requirement and requires low driving forces for the oscillation drive. In particular, the space requirement be so small that an application for bloom and stick systems in a simple manner is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Paar von benachbart übereinander angeordneten Führungselementen jeweils die Befestigung eines ersten Führungselementes an der Kokille und die Befestigung eines zweiten Führungselementes an der Kokillen-Stützeinrichtung im wesentlichen übereinander angeordnet sind, wobei mindestens ein erstes Führungselement sich von der Kokillen-Stützeinrichtung zur Kokille in einer ersten Richtung und mindestens ein zweites Führungselement sich von der Kokillenstützeinrichtung zur Kokille in einer zur ersten Richtung entgegengesetzten Richtung erstreckt.This object is achieved in that in a pair of adjacent one above the other guide elements each fastening a first Guide element on the mold and the attachment of a second guide element the mold support device are arranged substantially one above the other, wherein at least one first guide element extends from the mold support device to the mold a first direction and at least a second guide element from the Mold support device for the mold in a direction opposite to the first direction extends.

Gemäß einer bevorzugten Ausführungsform sind an der Kokille jeweils mindestens ein sich zur Kokillen-Stützeinrichtung und an der Kokillen-Stützeinrichtung jeweils mindestens ein sich zur Kokille erstreckender Stützarm 5 vorgesehen, die in etwa parallel zueinander und in Oszillationsrichtung gesehen einander etwa überdeckend angeordnet sind, und erstreckt mindestens ein Führungselement sich von dem Endbereich des einen Stützarms zu dem Endbereich des anderen Stützarms und ist dort selbst jeweils befestigt. According to a preferred embodiment, there are at least one each on the mold at least one each for the mold support device and on the mold support device Support arm 5 extending to the mold is provided, which is approximately parallel to one another and in Seen oscillation direction are arranged approximately overlapping each other, and extends at least one guide element extends from the end region of the one support arm to the one End region of the other support arm and is attached there itself.

Zur kippsicheren Abstützung der Kokille ist es zweckmäßig, daß jeweils mindestens zwei erste Führungselemente und zwei zweite Führungselemente vorgesehen sind, wobei jeweils von einem ersten und einem zweiten Führungselement gebildete Gruppen in einem in Oszillationsrichtung vorgesehenen Abstand voneinander angeordnet sind. Bei dieser Ausführungsform übernimmt der Oszillationsantrieb keine Führungskräfte. Für den Fall, daß die Kokille über den Oszillationsantrieb kippsicher abgestützt ist, d.h. durch den Oszillationsantrieb gehindert ist zu kippen, z.B. über Exzenterantriebe in Oszillation versetzt wird, wie dies in der EP-A- 0 150 357 beschrieben ist, genügt jedoch eine einzige, von einem ersten und einem zweiten Führungselement gebildete Gruppe.For tilt-proof support of the mold, it is advisable that at least two first guide elements and two second guide elements are provided, each groups formed by a first and a second guide element in an in The distance from the oscillation direction is arranged. At this According to one embodiment, the oscillation drive does not assume any managers. In case that the mold is supported against tilting via the oscillation drive, i.e. through the Oscillation drive is prevented from tipping, e.g. set into oscillation via eccentric drives as described in EP-A-0 150 357, however, a single one is sufficient first and a second guide element formed group.

Für Bogenkokillen ist die Stranggießeinrichtung vorteilhaft dadurch gekennzeichnet, daß ein erstes Führungselement und ein zu diesem etwa parallel angeordnetes zweites Führungselement im Winkel zu einem weiteren ersten Führungselement und dem dazu etwa parallel angeordneten zweiten Führungselement vorgesehen sind, wobei vorteilhaft für eine Bogenkokille die Längsachsen der Führungselemente in etwa auf Radiusstrahlen des von der Bogenkokille definierten Bogens orientiert sind.For arc molds, the continuous casting device is advantageously characterized in that a first guide element and a second arranged approximately parallel to this Guide element at an angle to a further first guide element and about this second guide element arranged in parallel are provided, advantageously for one Arc mold the longitudinal axes of the guide elements approximately on radius rays of the Arc mold are defined arc.

Zweckmäßig bilden das erste und das zweite Führungselement mit jeweils einem Stützarm 5 eine Baueinheit. Diese Ausführungsform gestattet eine einfache Konstruktion und ein einfaches Einbauen der Führungselemente bzw. auch einen einfachen Austausch derselben. Zudem lassen sich die Führungselemente in besonders einfacher Weise konstruktiv dort vorsehen, wo sie platzmäßig am leichtesten untergebracht werden können.The first and the second guide element expediently each form a support arm 5 a unit. This embodiment allows a simple construction and a easy installation of the guide elements or a simple exchange of the same. In addition, the guide elements can be constructed there in a particularly simple manner provide where they can be most easily accommodated in terms of space.

Vorteilhaft sind die Führungselemente von Federbändern, insbesondere jeweils von Federbänderpaketen gebildet, es ist jedoch auch möglich, Seile, Stäbe und/oder Membranen als Führungselemente einzusetzen.The guide elements of spring bands, in particular each of, are advantageous Spring packets are formed, but it is also possible to use ropes, rods and / or membranes use as guide elements.

Zweckmäßig sind die Führungselemente aus Stahl oder Kunststoff, wie z.B. Kohlefaser oder Glasfiber, gebildet.The guide elements made of steel or plastic, such as Carbon fiber or Glass fiber, formed.

Dies müßte jedoch nicht sein; sie könnten auch nebeneinander- oder hintereinanderliegend angeordnet sein. Bei Übereinander-Anordnung ist ein sich in Oszillationsrichtung III der Kokille 1 erstreckender Abstand 13 jeweils zwischen den Führungselementpaaren vorgesehen. Durch die Anordnung von insgesamt vier Führungselementpaaren 7, 10 ist die Kokille 1 ohne Rücksicht auf einen Oszillationsantrieb 14 kippsicher abgestützt.According to the embodiment shown in Fig. 1, each of two Guide elements 7 and 10 formed guide element pairs in plan view of the Continuous caster, i.e. provided overlapping each other in the direction of oscillation III. This but should not be; they could also be side by side or one behind the other be arranged.
