Abstract
Description
Die Erfindung betrifft eine Mehrfach-Stranggießanlage mit verstellbarer Gleitkokille, die zum simultanen Stranggießen wenigstens zweier Gußstränge mit im wesentlichen rechteckigen Querschnitten wenigstens zwei Gießformteile besitzt, deren Formatbreiten relativ zueinander verstellbar sind, wobei die beiden Gießformteile durch ein ihnen gemeinsam zugeordnetes, verschiebbares Zwischenteil derart miteinander in variabler Verbindung stehen, dass bei unveränderter Position der äußeren Schmalseitenwände der Kokille die Summe der Gießform-Volumina der Gießformteile in allen Einstellungen des Zwischenteils konstant ist und dem Zwischenteil Druckmittel zum Zusammenpressen der Breitseitenwände der Kokille gegen das Zwischenteil zugeordnet und gemeinsam mit diesem verschiebbar angeordnet und ausgebildet sind.The invention relates to a multiple-continuous casting with adjustable sliding mold, which has at least two casting moldings for simultaneous continuous casting of at least two casting strands having substantially rectangular cross-sections whose format widths are adjustable relative to each other, wherein the two mold parts by a jointly assigned, displaceable intermediate part in such a way variable connection are that with unchanged position of the outer narrow side walls of the mold, the sum of the mold volumes of the mold parts in all settings of the intermediate part is constant and the intermediate part pressure means for compressing the wide side walls of the mold against the intermediate part assigned and arranged together with this slidably and formed are.
Bei einer früher üblichen Verwendung in der Formatbreite nicht verstellbarer Kokillen war es erforderlich, die Kokillen zu wechseln. Hieraus ergab sich der Nachteil, dass eine vergleichsweise große Anzahl von aus Kupfer bestehenden und üblicherweise mit Kühlkanälen versehenen teuren Kokillen zur Verfügung gestellt werden mußten, wobei auch noch für die Umrüstung ein erheblicher Aufwand an Zeit und Kosten anfiel.In a previously common use in the format width non-adjustable molds, it was necessary to change the molds. This has resulted in the disadvantage that a comparatively large number of expensive molds made of copper and usually provided with cooling channels had to be made available, whereby a considerable expenditure of time and costs was also incurred for the conversion.
Durch die Einführung sogenannter Gleitkokillen mit veränderlichen Formatbreiten des zu gießenden Stranges wurden diese Nachteile wenigstens zum Teil überwunden.By introducing so-called sliding molds with variable format widths of the strand to be cast, these disadvantages have at least in part been overcome.
Aus der CH-PS 386 629 ist eine verstellbare Gleitkokille bekannt, die aus zwei relativ breiten, parallel angeordneten Wandungen sowie zwei jeweils rechtwinklig dazu angeordneten und einen rechteckigen Querschnitt vervollständigenden Gleitkokillenteilen besteht, deren Abstand relativ zueinander durch Spindel-Verstelleinrichtungen einstellbar ist.From CH-PS 386 629 an adjustable Gleitkokille is known, which consists of two relatively wide, parallel walls and two each arranged at right angles thereto and a rectangular cross-section complete Gleitkokillenteilen whose distance is adjustable relative to each other by spindle adjustment.
Zu Beginn dieser Entwicklung hat es sich jedoch gezeigt, dass Gleitkokillen Probleme hinsichtlich der Abdichtung an den Übergangsstellen zwischen den beweglichen und starren Kokillenteilen verursachen. Deswegen erfordern solche Übergangsstellen einen relativ großen Aufwand an sorgfältiger Bearbeitung, um Undichtigkeiten zu vermeiden.At the beginning of this development, however, it has been found that sliding molds cause problems with the sealing at the transition points between the movable and rigid mold parts. Therefore, such transition points require a relatively large amount of careful processing to avoid leaks.
Eine Verbesserung bekannter Gleitkokillen bezüglich der bei ihnen auftretenden Dichtigkeitsprobleme wird mit einer Ausgestaltung gemäß dem Dokument P 32 22 836.8 vorgeschlagen. Danach besteht die Gleitkokille zur Herstellung eines Gußstranges aus zwei relativ zueinander verschieblichen Gleitkokillenteilen, die vorzugsweise L-förmigen Grundriß haben.An improvement of known Gleitkokillen with respect to the leakage problems occurring in them is proposed with an embodiment according to the document P 32 22 836.8. Thereafter, there is the Gleitkokille for producing a Gußstranges of two relatively movable sliding mold parts, which preferably have L-shaped plan.
Eine Besonderheit dieses Vorschlags besteht darin, dass eine bevorzugt kreisbogenförmig ausgebildete Führung für die Gleitkokillenteile vorgesehen ist, die bewirkt, dass bei größerem Strangquerschnitt die Konizität vergrößert wird.A special feature of this proposal is that a preferred arc-shaped guide for the Gleitkokillenteile is provided, which causes the conicity is increased with a larger strand cross-section.
Das Dokument DE 32 24 065 A1 beschreibt eine verstellbare Gleitkokille für Zwillings-Stranggießanlagen zum Herstellen von Gußsträngen im wesentlichen rechteckigen Querschnitts, umfassend zwei Gleitkokillenteile, die mittels einer Antriebsvorrichtung im wesentlichen quer zur Strangrichtung relativ zueinander verschiebbar sind. Ein Gleitkokillenteil hat T-förmigen Grundriß und kommt mit der Stirnseite des in der Symmetrielinie liegenden Schenkels zur Anlage an der Innenfläche eines U-förmigen Gleitkokillenteils, dessen Schenkel-Stirnseiten zur Anlage an der Innenfläche des anderen Schenkels des T-förmigen Gleitkokillenteils kommen. Unabhängig von der Einstellung ist die Summe der Querschnitte und somit das Schluckvermögen der Kokille stets konstant. Die Gießstrahlmitte liegt stets im Zentrum der beiden Querschnitte, weil beide Kokillenteile gegeneinander bewegt werden.The document DE 32 24 065 A1 describes an adjustable sliding mold for twin-continuous casting for producing cast strands of substantially rectangular cross-section, comprising two Gleitkokillenteile which are displaceable relative to each other by means of a drive device substantially transverse to the strand direction. A Gleitkokillenteil has a T-shaped plan and comes with the end face of the lying in the line of symmetry leg to rest against the inner surface of a U-shaped Gleitkokillenteils, whose leg end faces to rest against the Inner surface of the other leg of the T-shaped Gleitkokillenteils come. Regardless of the setting, the sum of the cross sections and thus the swallowing capacity of the mold is always constant. The pouring jet center is always in the center of the two cross sections, because both mold parts are moved against each other.
Weil bei einer Mehrfachstranggießanlage unter Verwendung einer Gleitkokille die einzelnen Kokillenteile nach Maßgabe der einzustellenden Formatbreiten ein unterschiedliches Schluckvermögen für den Durchsatz der Schmelze besitzen, ist es erforderlich, Füllstandshöhen einer Mehrfach-Stranggießanlage mit mindestens zwei von einem gemeinsamen Verteilergefäß versorgten Stranggießkokillen sorgfältig zu regeln.Because in a Mehrfachstranggießanlage using a Gleitkokille the individual Kokillenteile according to the format widths to be set have a different absorption capacity for the throughput of the melt, it is necessary to carefully regulate levels of a multi-continuous casting with at least two supplied by a common distribution vessel continuous casting molds.
Ein derartiges Regelverfahren ist in der EP 0 149 447 A2 ausführlich beschrieben.Such a control method is described in detail in EP 0 149 447 A2.
Das bekannte Verfahren ist dadurch gekennzeichnet, dass durch Beobachtung des Schmelzenbadspiegels in einer der Stranggießkokillen Abweichungen des Niveaus des Schmelzenbadspiegels in dieser Stranggießkokille von einem Sollwert unter Veränderung der Ausziehgeschwindigkeit sämtlicher der aus den Stranggießkokillen austretenden Gußstränge kompensiert werden, wogegen Abweichungen des Niveaus des Schmelzenbadspiegels in der weiteren Stranggießkokille durch Veränderung der Schmelzzulaufmenge in der weiteren Stranggießkokille geregelt werden.The known method is characterized in that by observing the Schmelzenbadspiegels in one of the continuous casting molds deviations of the level of Schmelzenbadspiegels in this continuous casting mold from a target value under changing the extraction speed of all of the casting molds emerging from the casting molds are compensated, whereas deviations of the level of Schmelzenbadspiegels in the other Continuous casting mold can be controlled by changing the melt flow rate in the other continuous casting mold.
Aus der DE-1059626-B ist eine Stranggießskille mit vershallbarer Stirnwand bekannt, mit der für das Gießen mehrerer Barrenbreiten und eine bestimmte Barrendicke nur noch eine Kokille benötigt wird. Die verstellbare Stirnwand ist mit Laschen und Stellschrauben versehen, die es ermöglichen, sie in der jeweils gewünschten Stellung festzulegen.From DE-1059626-B is a continuous casting with vershallbarer end wall is known, with only one mold is needed for the casting of several bar widths and a certain bar thickness. The adjustable end wall is provided with tabs and set screws, which make it possible to set them in the desired position.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Gleitkokille für eine Mehrfach-Stranggießanlage nach der im Oberbegriff von Anspruch 1 genannten Art weiter zu entwickeln. Die Verbesserung beim sogenannten TWIN-Gießen soll dazu beitragen, Umbauzeiten und entsprechende Kosten signifikant zu verringern.Based on the aforementioned prior art, the present invention seeks to further develop a Gleitkokille for a multiple-continuous casting according to the type mentioned in the preamble of claim 1. The improvement in so-called TWIN casting should help to significantly reduce conversion times and corresponding costs.
Zur Lösung der Aufgabe wird bei einer Mehrfach-Stranggießanlage der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen, dass dem Zwischenteil einschließlich der mit diesem zusammenwirkenden Druckmittel eine Vorrichtung mit Antriebsmitteln zum Längsverschieben relativ zu den Kokillenbreitseitenwänden zugeordnet istTo solve the problem, it is proposed in a multiple-continuous casting referred to in the preamble of claim 1 with the invention that the intermediate part including the cooperating with this pressure means is associated with a device with drive means for longitudinal displacement relative to the Kokillenbreitseitenwänden
Mit großem Vorteil wird durch die erfindungsgemäße Bauart der Gleitkokille der Einsatz unterschiedlich breiter Mittelteile vermieden und insbesondere eine Ersparnis von Umbauzeiten verwirklicht, die außer einer Reduzierung der unmittelbaren Umbau-Arbeitskosten eine signifikante Verringerung der durch den Umbau bedingten Produktionsausfälle ergibt.With great advantage is avoided by the design of the invention the Gleitkokille the use of different widths middle parts and in particular realized a saving of conversion times, which results in a reduction of the immediate remodeling labor costs a significant reduction caused by the conversion production losses.
