Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Oszillieren einer Stranggießkokille, insbesondere für das Stranggießen von Dünnbrammen aus Stahl, umfassend eine oszillierbare Stranggießkokille, deren Hubtisch über mit einem ortsfesten Grundrahmen gelenkig verbundene Lenker geführt ist, und deren Oszillationsantrieb mit an einem ortsfesten Grundrahmen angeordneten Hydraulikaggregaten ausgebildet ist und die Achsen der Gelenke an den Hydraulikaggregaten, und die Achsen der Gelenke an den Lenkem parallel zueinander ausgerichtet sind.The invention relates to a device for oscillating a continuous casting mold, in particular for the continuous casting of thin slabs of steel, comprising a oscillating continuous casting mold, the lifting table of which has a fixed base frame articulated handlebar is guided, and their oscillation drive formed with hydraulic units arranged on a stationary base frame is and the axes of the joints on the hydraulic units, and the axes the joints on the links are aligned parallel to each other.
Beim Stranggießen wird die Kokille in eine periodische Oszillationsbewegung versetzt, um durch eine Relativbewegung zwischen Strang und Kokille die Reibung zwischen Kokille und Strang zu verringern. Dadurch wird eine unerwünscht hohe Reibung des Stranges an der Kokillenwand vermindert. Ferner wird auf der Badoberfläche in der Kokille befindliches körniges bis pulvriges Gießpulver nach Aufschmelzen als Gleitmittel in den Spalt zwischen Kokille und Strang eingezogen.In continuous casting, the mold is set in a periodic oscillation movement, to reduce the friction through a relative movement between the strand and the mold between the mold and the strand. This will make an undesirably high Friction of the strand on the mold wall is reduced. Furthermore, on the bathroom surface Granular to powdery casting powder in the mold after melting drawn into the gap between the mold and the strand as a lubricant.
Bei vertikal reziprozierender Bewegungen in Gießrichtung bzw. in Gegenrichtung sind Hub und Frequenz der Oszillation nach Maßgabe der Gießgeschwindigkeit einstellbare Parameter.With vertically reciprocating movements in the casting direction or in the opposite direction are the stroke and frequency of the oscillation according to the casting speed adjustable parameters.
Während eines Oszillationzyklus wechselt beim Vorbeigleiten der Kokille am Strang die Art der Reibung: During an oscillation cycle, the mold changes as the glides past Strand the type of friction:
Bei relativ zum Strang voreilender Geschwindigkeit der Kokille, dem Negativstrip,
sowie nach Richtungsumkehr zum Positivstrip, liegt Gleitreibung vor. Während der
Gleitreibung werden von der Kokille abwechselnd Zug- und Druckspannungen auf
die Strangschale übertragen.
Bei annähernd gleicher Geschwindigkeit zwischen Kokille und Strang, im Bereich
der Richtungsumkehr von Negativstrip zum Positivstrip, liegt Haftreibung vor, bei
der sich die resultierenden Zug- und Druckspannungen annähernd ausgleichen.
Bei Erhöhung oder Erniedrigung der relativen Kokillengeschwindigkeit reißt sich
die Kokille vom Strang los. Dies führt zum Stauchen und damit zu einer Geschwindigkeitserhöhung
der Strangschale, wenn sich die Kokille auf ihrem Weg
nach unten befindet, und umgekehrt zu einer Dehnung und damit zu einer Geschwindigkeitsreduzierung
der Strangschale, wenn sich die Kokille auf ihrem Weg
nach oben befindet.With the mold leading speed relative to the strand, the negative strip, and after reversing the direction to the positive strip, sliding friction is present. During sliding friction, tensile and compressive stresses are alternately transferred from the mold to the strand shell.
At approximately the same speed between the mold and the strand, in the area of reversal of direction from the negative strip to the positive strip, there is static friction at which the resulting tensile and compressive stresses almost equalize. When the relative mold speed is increased or decreased, the mold breaks free of the strand. This leads to compression and thus to an increase in the speed of the strand shell when the mold is on its way down, and conversely to an expansion and thus to a reduction in speed of the strand shell when the mold is on its way up.
Der abwechselnde Stauch- bzw. Dehnvorgang der Strangschale bewirkt insbesondere bei einer sinusförmigen Schwingung eine oszillierende Anregung des gesamten Stranges. Wenn diese in einem ungünstigen, beispielsweise harmonischen Frequenzbereich liegt, kann es u. a. zum Aufschwingen des Gießspiegels in der Kokille kommen. Ein derartiger nachteiliger Betriebszustand läßt sich insbesondere durch einen nicht-sinusförmigen Bewegungsablauf der Kokille vermeiden, wodurch eine periodisch auftretende Badspiegelschwankung erfolgreich gedampft wird.The alternating upsetting or stretching process of the strand shell causes in particular with a sinusoidal oscillation an oscillating excitation of the whole Strand. If this is in an unfavorable, for example harmonious Frequency range, it may. a. to swing the pouring level in the mold come. Such a disadvantageous operating state can be particularly avoid by a non-sinusoidal movement of the mold, whereby a periodic bath level fluctuation is successfully dampened becomes.
Aus dem Stand der Technik sind hydraulische Oszillationsantriebe für Hubtische von Stranggießeinrichtungen bekannt, die eine Kokillenoszillation mit beliebigen Geschwindigkeitskurven zulassen, beispielsweise entsprechend einer asymmetrisch Sinuskurve. Durch eine entsprechende Kurvenform kann die positive und negative Stripzeit in optimale Bereiche aufgeteilt werden, was sich vorteilhaft auf die Oszillationsmarken, deren Tiefe und Form auswirkt und eine Verbesserung der Oberflächenqualität bewirkt. Hydraulic oscillation drives for lifting tables are state of the art known from continuous casting, which a Kokillenoszillation with any Allow speed curves, for example corresponding to an asymmetrical one Sinusoid. The positive and negative strip time can be divided into optimal areas, which is beneficial on the oscillation marks, their depth and shape affects and an improvement of the Surface quality causes.
Beispielsweise beschreibt das Dokument DE 37 04 793 C2 eine Kokillen-Hubvorrichtung mit zwei an einem Hubtisch für die Stranggießkokille, oder direkt an dieser angelenkten, drehbar antreibaren Exenterwellen. Zwischen Drehantrieb und den Exenterwellen ist mindestens eine Gelenkwelle eingesetzt, bei welcher der von der Exenterwelle abgewandte Gelenkkopf lageveränderbar angeordnet ist und die Gelenkköpfe gegeneinander verdrehbar sind. Ein nicht-sinusförmiger Bewegungsablauf der Kokille wird bei dieser Vorrichtung durch den bewußten Gebrauch eines Kardanfehlers erzeugt, welcher auftritt, wenn eine Gelenkwelle nicht fluchtend zwischen den Wellen eingesetzt wird. Durch Veränderung von Höhe und seitliche Verschiebung des Drehantriebes sind unterschiedliche, nichtsinusförmige Bewegungsabläufe der Kokille realisierbar.For example, document DE 37 04 793 C2 describes a mold lifting device with two on a lifting table for the continuous casting mold, or directly on this articulated, rotatably drivable eccentric shaft. Between rotary drive and the eccentric shafts, at least one drive shaft is used, in which the joint head facing away from the eccentric shaft is arranged such that it can be changed in position and the rod ends are rotatable against each other. A non-sinusoidal sequence of movements the mold is used in this device through conscious use a gimbal error that occurs when a propeller shaft is not is used in alignment between the waves. By changing height and lateral displacement of the rotary drive are different, non-sinusoidal Movements of the mold can be realized.
Das Dokument EP 0 121 622 B1 beschreibt eine Stranggießanlage unter Verwendung einer in einem Rahmen gelagerten Kokille, welche durch eine elektrohydraulische Servoeinrichtung in Schwingungen versetzt wird. Die Schwingungserzeugung wird gemäß einem von einem Funktionsgenerator erzeugten vorgewählten Schwingungs-Ampitutensignal bei einer Frequenz betrieben, welche höher als die Eigenfrequenz der Schwingungsvorrichtung ist.Document EP 0 121 622 B1 describes a continuous caster using a mold mounted in a frame, which is controlled by an electro-hydraulic Servo device is vibrated. The generation of vibrations is preselected according to one generated by a function generator Vibration ampute signal operated at a frequency higher than that Natural frequency of the vibration device is.
Die noch unveröffentlichte Patentanmeldung 198 17 701.1 offenbart 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. Der Hubtisch ist mit unterhalb seiner Tischebene verlaufenden Führungsblöcken ausgebildet, zwischen welchen ein stationärer Spannblock angeordnet ist. Entlang der Kokillenschmalseiten sind 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 angelenschmalseite angeordneten Blattfedern paralleler Lage eingespannt. Der Oszillationsantrieb besteht aus vier Hydraulikzylindem, von denen jeweils zwei an jeder Kokillenseite angeordnet sind und mit ihrem einen Ende an den Führungsblöcken und mit ihrem anderen Ende an einem ortsfesten Tragrahmen befestigt sind.The as yet unpublished patent application 198 17 701.1 discloses a device for continuous casting of steel, consisting of an oscillating in the casting direction, continuous casting mold held in a lifting table and at least one oscillating drive acting on the lifting table. The lifting table is below his Guide plane extending guide blocks, between which a stationary clamping block is arranged. Along the mold narrow sides are below the table level on either side of the clamping block between or in this and the guide block adjacent to it at a distance above one another at least two individual, resiliently soft leaf springs in each other and in Reference to the respective narrow side on the opposite narrow mold side arranged leaf springs clamped in parallel position. The oscillation drive consists of four hydraulic cylinders, two on each Chill side are arranged and with one end on the guide blocks and are attached at their other end to a stationary support frame.
Eine in dem Dokument EP 0 732 978 B1 beschriebene Oszillationsvorrichtung benutzt als Führung je Kokillenseite zwei übereinanderliegend eingespannte Blattfederpakete. Hier ist je Seite ein Hydraulikzylinder mittig unter der Kokille angeordnet. Bei dieser Lösung wurde auf den Hubrahmen verzichtet - es wurde die Kokille unmittelbar auf den Blattfedem gelagert.An oscillation device described in document EP 0 732 978 B1 uses two clamped clamps on each side of the mold Leaf spring packages. Here, a hydraulic cylinder is arranged centrally under the mold on each side. With this solution, the lifting frame was dispensed with - it became the Chill mold stored directly on the leaf springs.
Nachteil bei einer Führung mit eingespannten Blattfedem ist die Begrenzung der Hubhöhe, die Aufnahme nur begrenzter Kräfte in Querrichtung der Blattfedem und die Federsteifigkeit der Führungsfeder, welche sich bei nicht-sinusförmigen Kokillengeschwindigkeiten negativ auf die Führungseigenschaft auswirkt.The disadvantage of a guide with clamped leaf springs is the limitation of the Lifting height, the absorption of only limited forces in the transverse direction of the leaf springs and the spring stiffness of the guide spring, which changes at non-sinusoidal mold speeds adversely affects leadership.

Die Oszillationseinrichtung zeigt, dass die Servo-Hydraulikzylinder bodenseitig über ein elastisches Befestigungselement auf dem Tragrahmen befestigt und ihre Kolbenstangen mit der Kokille verbunden sind.Document DE 195 41 164 A1 discloses an oscillation device for a Continuous casting mold, the guided on a support frame in the casting direction Continuous casting mold by means of servo hydraulic cylinders arranged on the support frame is moved oscillating. The oscillation device shows that the servo hydraulic cylinder on the bottom via an elastic fastening element on the Support frame attached and their piston rods are connected to the mold.
