Abstract

A strip casting plant has side limiting elements closely arranged next to a supporting belt. The side limiting elements, and preferably the liquid metal supply device as well, are capable of vibrating and are connected to a vibration generator. This prevents solidified material from adhering to the walls of the plant.

Description

BandgießanlageBelt caster
Beschreibungdescription
Die Erfindung betrifft eine Bandgießanlage, insbesondere für das Bandgießen von Stahl. Beim Bandgießen von Stahl kann entsprechend der benötigten Dicke beim fertiggewalzten Warmband (1 bis 3 mm) sowie bei der erforderlichen Warmverformung zur Erzielung ausreichender Materialeigenschaften die Gießdicke des Bandes weitgehend optimal gewählt werden (z. B. ca.10 mm).The invention relates to a strip caster, in particular for the strip casting of steel. When casting steel, the casting thickness of the strip can largely be optimally selected (e.g. approx. 10 mm) in accordance with the required thickness of the hot rolled strip (1 to 3 mm) and the required hot deformation to achieve sufficient material properties.
Aus DE 31 42 099 ist eine Vorrichtung zum Stranggießen von Metall bekannt, die eine Zuführeinrichtung für flüssiges Metall, ein Trägerband für flüssiges und erstarrtes Metall und an dem Trägerband dicht anliegende Seitenbegrenzungen aufweist. Die Seitenbegrenzungen sind nach Art einer Gliederkette an dem Trägerband befestigt.From DE 31 42 099 a device for the continuous casting of metal is known, which has a feed device for liquid metal, a carrier tape for liquid and solidified metal and side boundaries tightly against the carrier tape. The side boundaries are attached to the carrier tape in the manner of a link chain.
Eine derartige Konstruktion ist technisch recht aufwendig. Sie eignet sich auch im wesentlichen nur für relativ geringe Bandbreiten. Bei größeren Bandbreiten ist die durch die thermische Belastung aufgebrachte Spannung im Träger wesentlich höher als bei schmalen Bändern, so daß bei großen Bandbreiten die als Versteifung wirkende Konstruktion der kettenartig umlaufenden Seitenbegrenzung nicht einsetzbar ist.Such a construction is technically very complex. It is also essentially only suitable for relatively small bandwidths. In the case of larger bandwidths, the tension in the carrier brought about by the thermal load is substantially higher than in the case of narrow bands, so that the construction of the chain-like circumferential side boundary, which acts as a stiffener, cannot be used with large bandwidths.
Bei einer relativ zur Förderrichtung des vergessenen Bandes beziehungsweise des Trägers feststehenden Seitenbegrenzung kommt es vereinzelt während des Gießvorganges zum Anhaften von erstarrtem Stahl. Dies führt zu massiven Fehlern des Bandes und Betriebsstörungen bis hin zum Abbruch des Gießens. Ähnliche Probleme treten an der Zuführeinrichtung auf. Auch an dieser haftet vereinzelt erstarrter Stahl an, was zu den gleichen Schwierigkeiten führt.If the side boundary is fixed relative to the conveying direction of the forgotten band or the carrier, solidified steel will occasionally adhere during the casting process. This leads to massive errors in the strip and malfunctions, right up to the termination of the casting. Similar problems occur on the feeder. Here, too, solidified steel adheres, which leads to the same difficulties.
Es bestand daher die Aufgabe, eine Bandgießanlage anzugeben, bei der das Anhaften von erstarrtem Stahl an der Zuführeinrichtung und an den Seitenbegrenzungen zuverlässig vermieden wird.It was therefore the task of specifying a strip caster in which the sticking of solidified steel to the feed device and to the side boundaries is reliably avoided.
Diese Aufgabe wird gelöst, indem die Zuführeinrichtung und/oder die Seitenbegrenzungen in der Ebene des Trägerbandes schwingfähig ausgebildet sind und mit einer Einrichtung zur Erzeugung von Schwingungen verbunden sind. Durch diese Maßnahme kann das Anhaften von erstarrtem Material vermieden werden. Nach einer bevorzugten Ausführung sind die Schwingungen der Zuführeinrichtungen und/oder der Seitenbegrenzungen im wesentlichen senkrecht zur Förderrichtung des Bandes ausgebildet. Die Schwingung erfolgt also in der Ebene des Trägerbandes beziehungsweise des is vergessenen Stahlbandes, aber quer zur Förderrichtung. Dies hat den Vorteil, daß der konstruktive Aufwand geringer ist, als bei einer Schwingung in Förderrichtung, bei der die Seitenbegrenzung über die gesamte Länge exakt geführt werden müßte. Außerdem kann bei dieser Ausführung vorteilhaft die Schwingung im Bereich der metallurgischen Länge (vom Abgießbereich bis zur Durcherstarrung des Bandes) optimal eingestellt werden, indem zum Beispiel die Seitenbegrenzungen in diesem Bereich in einzelne Abschnitte mit jeweils optimaler Frequenz und Amplitude unterteilt werden.This object is achieved in that the feed device and / or the side boundaries are designed so that they can vibrate in the plane of the carrier tape and are connected to a device for generating vibrations. This measure prevents the sticking of solidified material. According to a preferred embodiment, the vibrations of the feed devices and / or the side boundaries are essentially perpendicular to the conveying direction of the belt. The vibration takes place in the plane of the carrier belt or the forgotten steel belt, but transversely to the direction of conveyance. This has the advantage that the design effort is less than in the case of an oscillation in the conveying direction in which the side boundary would have to be guided exactly over the entire length. In addition, in this embodiment, the vibration in the area of the metallurgical length (from the casting area to solidification of the strip) can advantageously be set optimally, for example by dividing the side boundaries in this area into individual sections, each with the optimum frequency and amplitude.
Nach einer weiter bevorzugten Ausführung sind die Seitenwandbegrenzungen in einem Winkel zueinander einstellbar. Dies bezieht sich sowohl auf die gegenüberliegenden Seitenwandbegrenzungen als auch die an der jeweiligen Seite gegebenenfalls vorhandenen Abschnitte. Hierdurch kann an dem vergessenen Band die Gleichmäßigkeit der Banddicke über die gesamte Breite verbessert werden. Insbesondere sind Seitenbegrenzungen auch gegenüber der Senkrechten zur Trägerbandoberfläche geneigt.According to a further preferred embodiment, the side wall boundaries can be set at an angle to one another. This applies both to the opposite side wall boundaries and to the sections that may be present on the respective side. As a result, the uniformity of the strip thickness over the entire width can be improved on the forgotten strip. In particular, side boundaries are also inclined with respect to the perpendicular to the surface of the carrier tape.
Nach einem bevorzugten Ausführungsbeispiel bestehen die Seitenwandbegrenzungen aus wassergekühlten Hohlprofilen.According to a preferred embodiment, the side wall boundaries consist of water-cooled hollow profiles.
Die Einrichtungen zur Erzeugung der Schwingungen sind bevorzugt Exzenterantriebe, jedoch können auch Elektromagnete oder Hydraulikzylinder eingesetzt werden. Die Schwingungsform kann unter anderem sinusförmig, sägezahnförmig oder trapezförmig sein. Die Hubfrequenz beträgt zum Beispiel 50 Hz bei einem Hub von zum Beispiel 0,5 mm. Die Zufuhr des Kühlwassers erfolgt über flexible Schläuche. Bei einer bevorzugt über dem vergessenen Band vorhandenen Abdeckung ist zur Abdichtung zwischen den Seitenbegrenzungen und der Abdeckungen eine Schicht aus temperaturbeständigem Dichtmaterial, insbesondere aus Keramikfaserfilz angeordnet. Eine entsprechende Abdichtung ist zwischen der Zuführeinrichtung und dem Trägerband vorgesehen, wobei bevorzugt zwischen dem Trägerband und der Abdichtung noch ein Aluminiumblech eingeschoben ist, so daß bei einer Schwingung nur eine Reiativbewegung zwischen der Filzschicht und dem Aluminiumblech erfolgt. Die Zuführeinrichtung und die Seitenbegrenzungen sind bevorzugt durch Schraubenfedern gehalten. Nach einer weiter bevorzugten Ausführung können die Begrenzungen gleichzeitig sowohl senkrecht als auch parallel zur Bandbewegung (Gießrichtung) schwingen, so daß sich insgesamt eine auch in Gießrichtung wirkende Schubkraft auf die Bandkante ergibt. Insbesondere weist die Schwingung Komponenten in allen drei Raumrichtungen auf.The devices for generating the vibrations are preferably eccentric drives, but electromagnets or hydraulic cylinders can also be used. The waveform can be sinusoidal, sawtooth-shaped or trapezoidal. The stroke frequency is, for example, 50 Hz with a stroke of, for example, 0.5 mm. The cooling water is supplied via flexible hoses. In the case of a cover which is preferably present over the forgotten band, a layer of temperature-resistant sealing material, in particular of ceramic fiber felt, is arranged for sealing between the side boundaries and the covers. A corresponding seal is provided between the feed device and the carrier tape, an aluminum sheet preferably being inserted between the carrier tape and the seal, so that in the event of an oscillation there is only a relative movement between the felt layer and the aluminum sheet. The feed device and the side boundaries are preferably held by coil springs. According to a further preferred embodiment, the boundaries can simultaneously oscillate both perpendicularly and parallel to the belt movement (casting direction), so that overall a thrust force also acts on the belt edge in the casting direction. In particular, the vibration has components in all three spatial directions.
Des weiteren kann die Schwingung senkrecht zur Bandoberfläche erfolgen.Furthermore, the vibration can take place perpendicular to the belt surface.
In einer besonderen Ausführung erfolgt die Anregung der Schwingungen durch Schläge in Längs- oder Querrichtung der Seitenbegrenzung. Hierdurch können schlagartig Longitudinalwellen aufgebracht werden, mit denen das Anhaften wirkungsvoll unterbunden werden kann. In a special version, the vibrations are excited by strikes in the longitudinal or transverse direction of the side boundary. In this way, longitudinal waves can suddenly be applied, with which the adherence can be effectively prevented.
