Description

Die Erfindung betrifft eine Einrichtung zum Stranggießen von Stahl, bestehend aus einer in Gießrichtung oszillierenden, in einem Hubtisch gehaltenen Stranggießkokille und mindestens einem auf den Hubtisch wirkenden Oszillationsantrieb.The invention relates to a device for the continuous casting of steel, consisting of a continuous casting mold that oscillates in the casting direction and is held in a lifting table and at least one oscillation drive acting on the lifting table.

Aus dem Stand der Technik sind hydraulische Oszillationsantriebe für Hubtische von Stranggießeinrichtungen bekannt, die eine Kokillenoszillation mit beliebigen Geschwindigkeitskurven zulassen, beispielsweise entsprechend einer asymmetrischen Sinuskurve. Der technische Hintergrund für die Einflußnahme auf die Oszillationsbewegung des Hubtisches und damit der Kokille besteht darin, die Schmierzeit zwischen der Kokillenwand und der Stranghaut zu verlängern und die Negativ-Stripzeit optimal zu gestalten. Diese Effekte wirken sich vorteilhaft auf die Oszillationsmarkenausbildung, insbesondere die Oszillationsmarkentiefe aus. Außerdem verbessert sich die Temperaturkonstanz der Stranghaut über die gesamte Breite der Kokille.Hydraulic oscillation drives for lifting tables are from the prior art Continuous caster known, the mold oscillation with any speed curves allow, for example, according to an asymmetrical Sinusoid. The technical background for influencing the oscillation movement of the lifting table and thus the mold is the lubrication time extend between the mold wall and the strand skin and the To optimally design negative strip time. These effects have a beneficial effect on the Oscillation mark formation, in particular the oscillation mark depth. In addition, the temperature constancy of the strand skin improves over the whole Width of the mold.

Aus der DE 43 41 719 C1 geht beispielsweise eine Einrichtung zum Stranggießen von Stahl mit einer in Gießrichtung oszillierenden Stranggießkokille hervor, die mit einem hydraulischen Oszillationsantrieb verbunden ist, der neben den üblichen sinusförmigen Oszillationskurven auch andersförmige Oszillationskurven zuläßt. Die Stranggießkokille ist an sich quer zur Gießrichtung erstreckenden, beidendig fest ein- und vorgespannten Federpaketen gelagert, die sich auf beiden Seiten der Stranggießkokille seitlich neben deren Schmalseitenplatten befinden. Mittig zwischen den übereinander angeordneten Federpaketen befindet sich jeweils ein Befestigungsblock, unter dem jeweils der als Servo-Hydraulikzylinder ausgebildete, insgesamt somit zwei Zylinder umfassende Oszillationsantrieb angeordnet ist. Die Befestigungsblöcke übertragen die von den Hydraulikzylindern ausgeführte Oszillationsbewegung auf die an ihnen befestigte Kokille.DE 43 41 719 C1, for example, describes a device for continuous casting Steel with a continuous casting mold oscillating in the casting direction, which with a hydraulic oscillation drive is connected, which in addition to the usual sinusoidal Oscillation curves also allow differently shaped oscillation curves. The continuous casting mold is in itself extending transversely to the casting direction, both ends firmly in and preloaded spring assemblies mounted on both sides of the continuous casting mold are located to the side of their narrow side panels. In the middle between the one spring block is located one above the other, below which the total designed as a servo hydraulic cylinder thus two-cylinder oscillation drive is arranged. The mounting blocks transmit the oscillation movement carried out by the hydraulic cylinders on the mold attached to them.

Weiterhin ist aus dem Stand der Technik eine Oszillationseinrichtung für eine Stranggießkokille mit einem sogenannten Parallelogramm-Hebelsystem bekannt. An einem Lagerständer sind Parallel-Lenker schwenkbar geführt, die den Kokillentisch mit der Kokille tragen. Zur oszillierenden Bewegung der Stranggießkokille sind Servo-Hydraulikzylinder vorgesehen. Die Servozylinder sind mit ihrer Bodenplatte ortsfest verankert und mit ihrer Kolbenstange gelenkig mit dem Kokillentisch verbunden. Die Seitenverlagerung des Kokillentisches wird durcch ein elastisches Verbindungselement ausgeglichen.Furthermore, an oscillation device for a continuous casting mold is from the prior art known with a so-called parallelogram lever system. On one Warehouse stands are pivoted parallel to the handlebars that connect the mold table with the Wear a mold. Servo hydraulic cylinders are used to oscillate the continuous casting mold intended. The servo cylinders are anchored in place with their base plate and articulated with its piston rod to the mold table. The side shift the mold table becomes an elastic connecting element balanced.

Ein Nachteil des Parallelogramm-Hebelsystems ist der hohe Raumbedarf, der für die Installation einer solchen Oszillationseinrichtung in bestehenden Stranggießanlagen erforderlich ist.A disadvantage of the parallelogram lever system is the high space requirement for it Installation of such an oscillation device in existing continuous casting plants is required.

Ausgehend von diesem Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine Stranggießeinrichtung der eingangs erwähnten Art zu schaffen, mit der sich nahezu beliebige Geschwindigkeitskurven des Hubtisches fahren lassen und die zugleich massearm und räumlich kompakt bautStarting from this prior art, the object of the invention is therefore to create a continuous caster of the type mentioned, with who can drive almost any speed curve of the lifting table and that is both compact and compact

Im einzelnen wird die Aufgabe bei einer Einrichtung der eingangs erwähnten Art dadurch gelöst, daß der Hubtisch mit unterhalb seiner Tischebene verlaufenden Führungsblöcken ausgebildet ist, zwischen denen ein stationärer Spannblock angeordnet ist, und entlang der Kokillenschmalseiten unterhalb der Tischebene zu beiden Seiten des Spannblocks jeweils zwischen bzw. in diesem und dem zu ihm benachbarten Führungsblock im Abstand übereinander mindestens zwei einzelne, nachgiebig weiche Blattfedern in zueinander sowie in Bezug auf die jeweiligen an der gegenüberliegenden Kokillenschmalseite angeordneten Blattfedern paralleler Lage eingespannt sind. In particular, the task at a facility of the type mentioned solved in that the lifting table with extending below its table level Guide blocks is formed, between which a stationary clamping block is arranged, and along the mold narrow sides below the table level both sides of the clamping block between or in this and that to it adjacent guide block at least two individual, one above the other, compliantly soft leaf springs in each other as well as in relation to the respective at the opposite leaf springs arranged parallel leaf springs in a parallel position are clamped.

Der Kokillentisch kann beispielsweise aus zwei an den Kokillenschmalseiten angeordneten, U-förmigen Sattelträgern, die über parallel zu den Kokillenbreitseiten verlaufende Traversen miteinander verbunden sind, bestehen. Die nach unten weisenden Schenkel der Sattelträger bilden in diesem Fall die Führungsblöcke des Hubtisches, in deren Mitte der ortsfeste Spannblock angeordnet ist. Bei einer anderen Ausführung lassen sich die Sattelträger mit nach oben offenem U und aufrecht hochstehenden Schenkeln, d.h. umgekehrt vorsehen; an einem die Sattelträger überspannenden feststehenden Tragrahmen könnten die Hydraulikzylinder des Oszillationsantriebes dann hängend angeordnet werden.The mold table can, for example, consist of two arranged on the mold narrow sides, U-shaped saddle bars that are parallel to the mold broadsides trusses are interconnected, exist. The down In this case, pointing legs of the saddle carrier form the guide blocks of the Lift table, in the middle of which the stationary clamping block is arranged. Another one The saddle carrier can be designed with the U open at the top and upright upstanding legs, i.e. provide the other way round; the saddle carrier on one spanning fixed support frame could the hydraulic cylinder of the Oscillation drive can then be arranged hanging.

Während die bekannten, vorgespannten Blattfederpakete auch dazu dienen, die Kokille zu tragen, geht die Erfindung einen davon völlig abweichenden Weg. Denn die an jeder Kokillenschmalseite vorhandenen zwei Blattfederpaare aus voneinander parallel beabstandeten dünnen Einzel-Blattfedern übernehmen keine tragende Funktion mehr. Sie zentrieren den Hubtisch und ermöglichen eine taumelfreie Kokillenbewegung. Durch die jeweils in Längsrichtung und in der Bewegungsrichtung parallele Anordnung der Blattfedern an jeder Seite des Kokillensattels wird der Hubtisch und damit die Kokille exakt geführt. Bei einer auf zwei unabhängigen Hubtischen aufsitzenden Kokille wird durch die Parallelanordnung der dünnen, weichen Blattfedern gleichzeitig erreicht, daß die Einzelhubtische in der Waage gehalten werden. Die beiden Blattfederpaare an jeder Seite ermöglichen somit eine statische Lagerung und die Führung des Hubtisches in Quer- und in Längsrichtung. Aufgrund der weichen, dünnen Blattfedern, die keine wesentliche Gegenkraft ausüben und sich problemlos durchbiegen können, erlauben es zudem, eine beliebige Kurve, d.h. unterschiedliche Geschwindigkeiten zu fahren.While the known, preloaded leaf spring assemblies also serve the The invention goes a completely different way to wear mold. Because that There are two pairs of leaf springs from each other on each narrow mold side thin single leaf springs spaced parallel to each other do not take over load-bearing Function more. They center the lifting table and enable a wobble-free Mold movement. By in each case in the longitudinal direction and in the direction of movement parallel arrangement of the leaf springs on each side of the mold saddle Lift table and thus the mold guided exactly. With one on two independent The mold is mounted on lifting tables thanks to the parallel arrangement of the thin, soft leaf springs simultaneously achieved that the single lifting tables in the scales being held. The two pairs of leaf springs on each side thus allow one static storage and the guidance of the lifting table in the transverse and in the longitudinal direction. Because of the soft, thin leaf springs that do not exert any significant counterforce and can bend easily, also allow any curve, i.e. to drive different speeds.

Eine bevorzugte Ausführung der Erfindung sieht vor, daß der Oszillationsantrieb aus vier Hydraulikzylindern besteht, von denen jeweils zwei an jeder Kokillenseite angeordnet und mit einem Ende an den Führungsblöcken und mit ihrem anderen Ende an einem ortsfesten Tragrahmen befestigt sind. Somit können möglicherweise auftretende unterschiedliche Reibungskräfte an den Kokillenseiten über die vorzugsweise positions- oder kraftgeregelten Hydraulikzylinder abgefangen werden. Zudem läßt sich mit zwei an jeder Seite angeordneten Zylindern eine saubere und kontrollierte Hubtischbewegung erreichen, weil die Kräfte bzw. Kraftmomente immer im Gleichgewicht sind und durch die Federpaare aus einzelnen Blattfedern nicht ausgependelt werden.A preferred embodiment of the invention provides that the oscillation drive There are four hydraulic cylinders, two on each side of the mold arranged and with one end on the guide blocks and with the other End are attached to a stationary support frame. So possibly occurring different frictional forces on the mold sides over the preferably position or force-controlled hydraulic cylinders can be intercepted. moreover can with two cylinders arranged on each side a clean and achieve controlled lifting table movement because the forces or moments of force always are in equilibrium and are not due to the spring pairs made of individual leaf springs to be commuted.

In einer bevorzugten Ausgestaltung der Erfindung dient der Tragrahmen sowohl als ortsfeste Lagerung für die Hydraulikzylinder als auch die Spannblöcke. Das gesamte System ist damit in einem einzigen, gegenüber dem oszillierenden Hubtisch ortsfesten Rahmen gelagert. Alternativ ist es selbstverständlich auch möglich, daß die Hydraulikzylinder und die Spannblöcke jeweils auf unterschiedlichen, jedoch feststehenden Lagerflächen angeordnet sind.In a preferred embodiment of the invention, the support frame serves both as Fixed storage for the hydraulic cylinders as well as the clamping blocks. The entire The system is thus fixed in a single, fixed position relative to the oscillating lifting table Frame stored. Alternatively, it is of course also possible for the Hydraulic cylinders and the clamping blocks each on different, however fixed storage areas are arranged.

Als alternativer Oszillationsantrieb läßt sich vorteilhaft ein seitlich am Hubtisch angeordneter Kokillenschmalseitenantrieb einsetzen. Dies ist deshalb möglich, da die Stranggießeinrichtung aufgrund der je Kokillenschmalseite angeordneten zwei Blattfederpaare bereits exakt geführt istAs an alternative oscillation drive, one can advantageously be located on the side of the lifting table Insert the arranged mold side drive. This is possible because the Continuous casting device due to the two arranged on each mold narrow side Leaf spring pairs are already guided exactly

In einer vorteilhaften Ausgestaltung der Erfindung sind die Hydraulikzylinder in einer durch die Führungsblöcke gelegten Querschnittsebenen seitlich neben den Führungsblöcken angeordnet.In an advantageous embodiment of the invention, the hydraulic cylinders are in one cross-sectional planes placed by the guide blocks to the side of the guide blocks arranged.

In einer weiteren Ausgestaltung der Erfindung sind die Hydraulikzylinder mit einem Ende an einem unteren Abschnitt des Führungsblocks und mit dem anderen Ende oberhalb dieser Anlenkung an dem ortsfesten Tragrahmen befestigt. Durch die hieraus resultierende, hängende Anordnung der Hydraulikzylinder und des damit verbundenen Hubtisches ergibt sich eine verbesserte Eigenstabilität der beweglichen Teile der Stranggießeinrichtung.In a further embodiment of the invention, the hydraulic cylinders are with a End at a lower section of the guide block and the other end attached to the fixed support frame above this linkage. Through the resulting, hanging arrangement of the hydraulic cylinders and thus connected lifting table results in improved inherent stability of the movable Parts of the continuous caster.

Die Oberflächen der Breitseitenträger 6.1, 6.2 und des Schmalseitenträgers 5 bilden die Tischebene 4 zur Aufnahme der Kokille.At right angles from the narrow cross member 5 extend in the direction of Broadside of the mold broadside carriers 6.1 and 6.2, which at their other end also with a matching U-shaped saddle carrier 2 are connected. The surfaces of the broad side girders 6.1, 6.2 and des Narrow side support 5 form the table level 4 for receiving the mold.

Zwischen den Führungsblöcken 3.1 und 3.2 befindet sich mittig ein Spannblock 7, der auf einer Fundamentstütze 8 verankert ist. Zwei übereinander angeordnete, einzelne, dünne Blattfedern sind als Blattfederpaare 9.1, 10.1 bzw. 9.2, 10.2 an dem Spannblock 7 befestigt. Jede Blattfeder 9.1, 9.2 bzw. 10.1, 10.2 ist auf einer Seite mit dem Führungsblock 3.1 bzw. 3.2 und auf der anderen Seite an dem ortsfesten Spannblock 7 befestigt.A clamping block 7 is located in the middle between the guide blocks 3.1 and 3.2 is anchored on a foundation support 8. Two, one above the other, thin leaf springs are as leaf spring pairs 9.1, 10.1 and 9.2, 10.2 on the Clamping block 7 attached. Each leaf spring 9.1, 9.2 or 10.1, 10.2 is on one side with the guide block 3.1 or 3.2 and on the other side on the stationary Clamping block 7 attached.

Seitlich an den Führungsblöcken 3.1, 3.2 befinden sich Lagerflansche 12.1, 12.2, in denen eine Kolbenstange 13.1, 13.2 eines Hydraulikzylinders 14.1, 14.2 angelenkt ist.On the side of the guide blocks 3.1, 3.2 there are bearing flanges 12.1, 12.2, in which a piston rod 13.1, 13.2 of a hydraulic cylinder 14.1, 14.2 is articulated.

Mit ihrem unteren Ende stützen sich die Hydraulikzylinder 14.1, 14.2 gelenkig über Befestigungsflansche 15.1, 15.2 an Fundamentstützen 16.1, 16.2 ab.With their lower end, the hydraulic cylinders 14.1, 14.2 are supported in an articulated manner Fastening flanges 15.1, 15.2 on foundation supports 16.1, 16.2.

Zur Erläuterung des Ausführungsbeispiels in Fig. 2 mit "hängender" Anordnung des Hubtisches 1 wird auf die Erläuterung zu Fig. 1 Bezug genommen. Übereinstimmende Baugruppen tragen identische Bezugsziffern.To explain the embodiment in Fig. 2 with "hanging" arrangement of Lift tables 1 is referred to the explanation of FIG. 1. Matching Modules have identical reference numbers.

Der Hauptunterschied der Ausführungsform nach Fig. 2 besteht darin, daß der Spannblock 7 und die Hydraulikzylinder 14.1, 14.2 ihr Widerlager nicht in Fundamentstützen, sondern in einem einheitlichen Tragrahmen 18 finden, der eine hängende Anordnung des Hubtisches erlaubt. Zu diesem Zweck sind die Lagerflansche 12.1, 12.2 zur Aufnahme der Kolbenstangen 13.1, 13.2 (vgl. Fig. 1) im gezeigten Ausführungsbeispiel unten an den Führungsblöcken 3.1, 3.2 angeordnet. Der Tragrahmen 18 besitzt zu diesem Zweck in einer durch die Führungsblöcke 3.1,3.2 gelegten Querschnittsebene sich nach oben erstreckende Tragarme 19.1, 19.2, die jweils oben durch Querschenkel 21.1, 21.2 begrenzt werden. An den Querschenkeln 21.1, 21.2 sind die Hydraulikzylinder über ihre Zylinderböden gelenkig befestigt. Bei einer Abwandlung dieser Ausführung können die nach unten offenen U-förmigen Sattelträger und der feststehende Tragrahmen in der Zeichnungsebene der Fig. 2 um 180° nach oben geklappt, d.h. in umgekehrter Anordnung mit nach oben offenem U der Sattelträger und diese überbrückenden Tragrahmen 18 vorgesehen werden; in diesem Fall hängen die Zylinder an dem feststehenden Tragrahmen.The main difference of the embodiment of FIG. 2 is that the Clamping block 7 and the hydraulic cylinders 14.1, 14.2 do not have their abutments Foundation supports, but find in a unitary support frame 18, the one hanging arrangement of the lifting table allowed.
