Description

Die Erfindung betrifft eine Stranggießanlage, insbesondere eine Knüppel- oder Vorblockstranggießanlage, mit einer in einen rahmenförmigen Hubtisch einsetzbaren Kokille und einer an die Kokille anschließenden Strangführungseinrichtung, die aus mehreren, Strangführungsrollen tragenden Strangführungssegmenten gebildet ist und mit einer den Hubtisch abstützenden und bewegenden Kokillenoszilliereinrichtung.The invention relates to a continuous caster, in particular a billet or bloom caster, with one in a frame-shaped lifting table insertable mold and a strand guiding device connected to the mold, consisting of several strand guide segments carrying strand guide rollers is formed and with a supporting the lifting table and moving mold oscillating device.

An Stranggießanlagen wird generell die Forderung gestellt, Stränge mit unterschiedlichen Querschnittsabmessungen mit einem Minimum an Umrüstzeit und Austauschteilen zu gießen. Bei großformatigen Strängen erfolgt dies durch den Einsatz von formatverstellbaren Plattenkokillen, bei Strängen mit Knüppelquerschnitten und teilweise bei Strängen mit Vorblockquerschnitten werden Rohrkokillen eingesetzt, die bei einem Formatwechsel ausgetauscht werden. Der Austausch der Kokille allein reicht nicht aus, da der in seinem Inneren eine noch flüssige Zone aufweisende Strang insbesondere nach dem Austritt aus der Kokille eine versatzfreie Abstützung der heißen, noch dünnen und leicht verformbaren Strangschale benötigt und daher auch das nachgeordnete Strangführungssegment ausgetauscht werden muß.On continuous casting plants, the general requirement is to use strands different cross-sectional dimensions with a minimum of changeover time and casting replacement parts. This is done for large-sized strands through the use of format-adjustable plate molds, with strands with Billet cross-sections and partly for strands with bloom cross-sections tubular molds are used, which are exchanged when the format changes become. The replacement of the mold alone is not enough, as the one in his Inside a strand that is still liquid, especially after the Leaving the mold, a non-offset support of the hot, still thin and easily deformable strand shell needed and therefore that subordinate strand guide segment must be replaced.

Eine Stranggießanlage dieser Art ist bereits aus der DE-A 19 57 689 bekannt, bei der die Kokille, der die Kokille tragende Hubtisch, die Kokillenoszilliereinrichtung und ein erstes Strangführungssegment innerhalb eines lösbaren räumlichen Rahmens angeordnet ist. Dieser Rahmen ist mit all seinen Einbauten gemeinsam abhebbar und austauschbar. Gleichzeitig ist auch das darunter angeordnete nächste Strangführungssegment zugänglich und ebenfalls austauschbar. In der konkret beschriebenen Ausführungsform sind die Kokille mit dem Hubtisch und das erste Strangführungssegment getrennt voneinander im räumlichen Rahmen angeordnet. Eine Justierung dieser Bauteile zueinander ist bei dieser Anordnung nicht automatisch gegeben. Gerade das Fluchten von der durch die formgebende Innenwand der Kokille gebildeten Ebene und der an die Rollen des ersten Strangführungssegments anlegbaren Erzeugenden (Strangoberfläche) ist wegen der dünnen Strangschale besonders wichtig und erfordert eine genaue und aufwendige Justierung.A continuous caster of this type is already known from DE-A 19 57 689 known, in which the mold, the lifting table supporting the mold, the Mold oscillating device and a first strand guide segment within a detachable spatial frame is arranged. This frame is with everything its internals can be lifted off and replaced. At the same time, too the next strand guide segment arranged below is accessible and also interchangeable. In the specifically described embodiment the mold with the lifting table and the first strand guide segment separated arranged from each other in the spatial frame. Adjusting this Components to each other are not automatically given in this arrangement. Just the escape from the mold through the mold's inner wall level formed and to the roles of the first strand guide segment Generable generators (strand surface) is special because of the thin strand shell important and requires precise and complex adjustment.

Aus der AT-PS 347 057 ist eine Stranggießanlage bekannt, bei der eine Kokille und das ausgangsseitig an die Kokille angebaute Fußrollengerüst, sowie eine dem Fußrollengerüst nachgeordnete Biegezone durch einen die Kokille und die Biegezone erfassenden Tragrahmen aus der Stranggießanlage gemeinsam ausbaubar ist. Diese Konzeption erfordert ein mehrfaches Justieren der einzelnen Bauteile zueinander. Einerseits muß die Wandung des Kokillenhohlraumes zur Erzeugenden der nachfolgenden Fußrollen, sowie auch diese Fußrollen zu den Strangführungsrollen der nachgeordneten Biegezone mit einem entsprechenden Meßlineal eingestellt werden. Weiters bleibt es unklar, wie die Justierung weiterer im Kokillenbereich angeordneter Bauteile, wie z. B. der Kokillenrührer oder die Gießspiegelmeßeinrichtung eingebaut werden könnten.From AT-PS 347 057 a continuous caster is known in which a mold and that castor frame attached to the mold on the output side, as well as a castor frame Subsequent bending zone by a support frame which grips the mold and the bending zone can be removed from the continuous caster. This conception requires a multiple adjustment of the individual components to each other. On the one hand, the wall of the Mold cavity for generating the subsequent casters, as well as these Casters to the strand guide rollers of the downstream bending zone with one appropriate ruler can be set. Furthermore, it remains unclear how the adjustment other components arranged in the mold area, such as. B. the mold stirrer or Casting level measuring device could be installed.

Aufgabe der Erfindung ist es daher, obige Nachteile zu vermeiden und aus den bekannten, üblicherweise bei einer Stranggießanlage verwendeten Komponenten Kokille, Hubtisch, Kokillenoszilliereinrichtung, der nachgeordneten Strangführungseinrichtung und gegebenenfalls vorhandenen Zusatzeinrichtungen, wie Kokillenrührer und Gießspiegelmeßeinrichtung, eine Baueinheit zu bilden, bei der kurze Wechselzeiten durch die Bildung eines formatbezogenen Maschinenblocks und ein reduzierter Instandhaltungsaufwand durch den modularen Aufbau der Maschinenkomponenten möglich ist.The object of the invention is therefore to avoid the above disadvantages and from the known Components usually used in a continuous caster, mold, lifting table, Kokillenoszilliereinrichtung, the downstream strand guide and any additional devices, such as mold stirrers and Gießspiegelmeßeinrichtung to form a unit in the short change times by the Formation of a format-related machine block and a reduced maintenance effort is possible due to the modular structure of the machine components.

Gelöst wird diese Aufgabe dadurch, daß ein erstes Strangführungssegment in einem nachgeordneten zweiten Strangführungssegment lösbar integriert ist, daß ein Kokillenrührer auf dem zweiten Strangfiihrungssegment abgestützt ist und daß das zweite Strangführungssegment im Bereich der Kokille hochgezogene Stützen trägt, welche Stützen Auflagen für die Kokille oder den die Kokille tragenden Hubtisch und Verbindungselemente für den gemeinsamen Ausbau von Kokille, Kokillenrührer und zweitem Strangführungssegment aufweisen. Ein besonderer Vorteil dieser Anordnung besteht darin, daß lediglich für das eine Baueinheit bildende erste und zweite Strangführungssegment eine Justierung in der Werkstätte notwendig ist. This object is achieved in that a first strand guide segment in one subordinate second strand guide segment is releasably integrated that a mold stirrer is supported on the second strand guide segment and that the second The strand guide segment in the area of the mold supports which supports Support for the mold or the lifting table supporting the mold and connecting elements for the joint expansion of the mold, mold stirrer and the second Have strand guide segment. A particular advantage of this arrangement is that that only for the first and second strand guide segment forming a structural unit Adjustment in the workshop is necessary.

Nach besonderen Ausführungsformen ist das erste Strangführungssegment als Fußrollengerüst und das zweite Strangführungssegment als Biegezone ausgebildet. Die Verbindungselemente werden von Haken oder Ösen gebildet.According to special embodiments, the first strand guide segment is as Castor frame and the second strand guide segment designed as a bending zone. The Fasteners are formed by hooks or eyes.

Eine vorteilhafte Weiterbildung der Erfindung ergibt sich dadurch, daß eine Gießspiegelmeßeinrichtung, bestehend aus einem Strahlerelement und einem Szintillationszähler auf dem Kokillenrührer oder auf den Stützen des zweiten Strangführungssegmentes angeordnet ist. Als Strahlerelement wird bevorzugt ein Kobaltstrahler eingesetzt. Durch diese Anordnung ist es möglich, die nicht mitoszillierende Gießspiegelmeßeinrichtung sehr nahe am Kokillenhohlraum anzuordnen und somit den Kobaltstrahler in seiner Kapazität möglichst klein zu halten und gleichzeitig eine stabile und klar definierte Position für die Gießspiegelmeßeinrichtung zu erhalten.An advantageous development of the invention results from the fact that a Casting level measuring device, consisting of a radiator element and a Scintillation counter on the mold stirrer or on the supports of the second Strand guide segment is arranged. A is preferred as the radiating element Cobalt heater used. With this arrangement it is possible to avoid oscillating Gießspiegelmeßeinrichtung very close to the mold cavity and thus the To keep cobalt emitters as small as possible while maintaining a stable and Obtain a clearly defined position for the mold level measuring device.

Eine besonders stabile und versatzfrei arbeitende Stranggießanlage ist dadurch erzielbar, daß die Kokillenoszilliereinrichtung als Vier-Exzenteroszillierer mit Federbandführung ausgebildet ist.A particularly stable and offset-free continuous casting plant can be achieved in that the mold oscillation device as a four-eccentric oscillator with spring band guide is trained.

Eine Ausführungsform der Erfindung ist anhand zweier Figurendarstellungen näher erläutert, wobei Fig. 1 einen schematischen Längsschnitt durch die Stranggießanlage im Bereich der Kokille und der daran anschließenden Strangführungseinrichtung zeigt. Fig. 2 veranschaulicht dieselbe Ausführungsform mit geänderter Schnittführung.An embodiment of the invention is explained in more detail using two figure representations, 1 shows a schematic longitudinal section through the continuous casting plant in the area of Mold and the subsequent strand guide device shows. Fig. 2 illustrates the same embodiment with a modified cut.

Die Stranggießanlage ist an einem ortsfesten Anlagentragwerk 1 abgestützt. Auf einem Stützrahmen 2 des Anlagentragwerkes 1 ist die Kokillenoszilliereinrichtung 3 fixiert, die von einem Vier-Exzenteroszillierer 4 und einer Federbandführung 5 gebildet ist. Die Kokillenoszilliereinrichtung 3 ist im Detail in der AT-PS 384 970 dargestellt und beschrieben. Sie besteht im wesentlichen aus vier in den Eckbereichen des Stützrahmens 2 angeordneten Exzentern, die über einen gemeinsamen Drehantrieb angetrieben werden, wobei die so erzeugte Drehbewegung durch kurze Pleuel in eine vertikale Oszillierbewegung umgesetzt wird. Die Pleuel der Kokillenoszilliereinrichtung 3 sind mit einem rahmenförmigen Hubtisch 6 verbunden, der die Oszillierbewegung aufnimmt und auf die Kokille 8 überträgt. Wie aus Fig. 2 ersichtlich, ist zwischen dem Hubtisch 6 und dem Stützrahmen 2 eine Federbandführung 5 angeordnet, die im wesentlichen aus mehreren Federbändern 7 oder vergleichbaren elastischen Elementen gebildet ist, die mit ihren Enden am Stützrahmen 2 ortsfest eingespannt und in ihrem Mittenbereich mit dem Hubtisch 6 verbunden sind. Damit ist eine exakte Positionierung der oszillierenden Anlagenteile gegenüber den feststehenden Anlagenteilen, im besonderen das Fluchten der oszillierenden Kokille 9 zur nachgeordneten am Anlagentragwerk 1 gelagerten Strangführungseinrichtung 9 gegeben.The continuous casting plant is supported on a fixed plant structure 1. On one Support frame 2 of the plant structure 1, the Kokillenoszilliereinrichtung 3 is fixed by a four eccentric oscillator 4 and a spring band guide 5 is formed. The Mold oscillating device 3 is shown and described in detail in AT-PS 384 970. It consists essentially of four arranged in the corner regions of the support frame 2 Eccentrics, which are driven by a common rotary drive, whereby the rotation thus generated by short connecting rods in a vertical Oscillating movement is implemented. The connecting rods of the mold oscillating device 3 are connected to a frame-shaped lifting table 6, which Picks up oscillating movement and transfers it to the mold 8. As from Fig. 2 can be seen, between the lifting table 6 and the support frame 2 Spring band guide 5 arranged, which consists essentially of several spring bands 7 or comparable elastic elements is formed with their ends clamped in place on the support frame 2 and in their central area are connected to the lifting table 6. This is an exact positioning of the oscillating system parts compared to the fixed Plant parts, in particular the alignment of the oscillating mold 9 for subordinate strand guide device 9 mounted on the system structure 1 given.

Die Kokille 8 besteht aus dem Kokillenelement 10 und einem portalartigen Kokillenrahmen 11, in den das Kokillenelement 10 eingesetzt ist. Das Kokillenelement 10 weist einen dem Format des zu gießenden Stranges entsprechenden Formhohlraum auf, der von einem Kupferrohr oder aus Kupferplatten gebildet ist und eine Hinterstützungskonstruktion mit den entsprechenden Einrichtungen für die Kokillenkühlung.The mold 8 consists of the mold element 10 and a portal-like one Mold frame 11, in which the mold element 10 is inserted.
