Abstract

The invention relates to a method for continuously casting a metal strip (7) having a thickness of between 1 and 10 mm, especially a steel strip, between two coolable, radially interspersed casting rollers (6) in the form of a mould which can be moved in a rotating manner. Said casting rollers define a casting gap (11) between each other, and the front sides of the casting rollers (6) comprise adjustable sealing elements (8). In order to optimise the seal, the front-sided sealing elements (8) are displaced along an approximately vertical plane in the casting direction, the displacement being superposed by an oscillating movement. Especially oscillating displacement means are provided therefor.

Description

Verfahren zum Stranggϊeßen eines Metall bandesProcess for the continuous casting of a metal strip
Die Erfindung betrifft ein Verfahren zum Stranggießen eines Metallbandes, im Dickenbereich zwischen 1 und 10 mm insbesondere eines Stahlbandes, zwischen zwei nach Art einer umlaufend bewegbaren Kokille im radialen Abstand angeordneten kühlbaren Gießrollen, welche zwischen sich einen Giesspalt begrenzen, wobei die Stirnseiten der Gießrollen anstellbare und/oder einstellbare Abdichtungselemente aufweisen.The invention relates to a process for the continuous casting of a metal strip, in the thickness range between 1 and 10 mm, in particular a steel strip, between two coolable casting rolls arranged in the manner of a circumferentially movable mold, which delimit a casting gap between them, the end faces of the casting rolls being adjustable and / or have adjustable sealing elements.
Beim sogenannten Zwei-Rollen-Gießverfahren erfolgt eine stirnseitige Abdichtung der Rolle bzw. des zwischen diesen ausgebildeten Gießspaltes üblicherweise durch feuerfeste Platten. Eine Voraussetzung für ein fehlerfreies Gieß- produkt ist, dass keine Erstarrung der beiden Strangschalen an den feuerfesten Schmalseitenplatten erfolgt. Kommt es jedoch im Gießbetrieb auch nur kurzzeitig zu einer Erstarrung von Gießmetall an der feuerfesten Platte, tritt in diesem Bereich ein erhöhter Verschleiß ein. Dieser führt im weiteren Verlauf zu einer Finnenbildung an der Bandkante, die den Verschleiß der feuerfesten Schmal- Seitenabdichtung weiter erhöht. Dadurch wird die Produktqualität verschlechtert und die Standzeit der stirnseitigen Schmalseitenabdichtung sowie die hiervon abhängige mögliche Gießzeit verringert.In the so-called two-roller casting process, the end of the roller or the casting gap formed between them is usually sealed by means of refractory plates. A prerequisite for a faultless cast product is that the two strand shells do not solidify on the refractory narrow side plates. However, if the casting metal solidifies briefly on the refractory plate in the casting operation, increased wear occurs in this area. In the further course, this leads to the formation of fins on the belt edge, which further increases the wear of the refractory narrow side seal. As a result, the product quality is deteriorated and the service life of the narrow face seal on the end face and the possible casting time dependent on it are reduced.
Dementsprechend sind im Stand der Technik Konstruktionsvorschläge zur Lö- sung des Problems einer stirnseitigen Abdichtung der Gießrollen bekannt.Accordingly, design proposals for solving the problem of sealing the casters at the end are known in the prior art.
Das Dokument EP 0 714 715 A1 beschreibt Mittel zur Aufnahme einer seitlichen Abdichtung an den Gießrollen einer Produktionsvorrichtung des Typs der "Zwei-Rollen-Bandgießmaschine", umfassend ein in Richtung der Rollenachsen verschiebbares Fördermittel mit einer Vorrichtung zur Erzeugung einer Schubkraft für das Fördermittel, sowie eine Platte zum Zusammenwirken mit dem Fördermittel, die an diesem befestigt ist. Die Platte weist zumindest zwei in Achsrichtung der Rollen verschiebbare Gleitbacken auf, die an den Stirnseiten der Gießrollen federnd anlegbar sind.Document EP 0 714 715 A1 describes means for receiving a lateral seal on the casting rolls of a production device of the type of the "two-roll belt casting machine", comprising a conveying means which can be displaced in the direction of the roll axes and a device for generating a pushing force for the conveying means, and a plate to work with Funding attached to this. The plate has at least two sliding jaws which can be displaced in the axial direction of the rollers and which can be resiliently applied to the end faces of the casting rollers.
Das Dokument WO 99/32247 beschreibt ein Verfahren und eine Vorrichtung zur Kontrolle der Position von stirnseitigen Dichtungsmitteln bei einem Gießprozess in einer Zwei-Rollen-Bandgießmaschine. Folgende Arbeitsschritte werden durchgeführt: Berechnen der Position eines Erstarrungpunktes relativ zur Drehkraft der Doppelrollen. Messen der Drehkraft der Doppel-Rollen beim Gießprozess mit Hilfe einer Kraftmesszelle. Ermitteln, ob die Position des Erstarrungs- punktes bei der gemessenen Wälzkraft der Doppelrollen der aktuellen Höhe der stirnseitigen Dichtungsmittel entspricht, und Einstellen der stirnseitigen Dichtungsmittel zur Position des Erstarrungspunktes entsprechend der gemessenen Wälzkraft der Rollen.The document WO 99/32247 describes a method and a device for checking the position of face sealants during a casting process in a two-roll belt casting machine. The following work steps are carried out: Calculating the position of a solidification point relative to the torque of the double rollers. Measuring the torque of the double rollers during the casting process using a load cell. Determine whether the position of the solidification point at the measured rolling force of the double rollers corresponds to the current height of the sealing means on the front, and adjust the front sealing means to the position of the solidification point according to the measured rolling force of the rollers.
Das Dokument JP 7 290 205 beschreibt eine Vorrichtung zum Messen des Ab- standes zwischen seitlichen Stauklötzen einer Stranggießanlage für schmale Bänder.The document JP 7 290 205 describes a device for measuring the distance between side blocks of a continuous caster for narrow strips.
Das Dokument JP 6 015 414 offenbart ein Verfahren und eine Vorrichtung für das Zwei-Rollen-Gießen mit Kontrollmitteln für die einstellbare Hub-Position der Stirnseitenabdichtungselemente.Document JP 6 015 414 discloses a method and an apparatus for two-roll casting with control means for the adjustable stroke position of the end face sealing elements.
Ausgehend vom vorgenannten Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, ein Verfahren und eine Vorrichtung anzugeben, die den technischen Aufwand vorbekannter Abdichtungselemente für den Gießspalt bei Zwei-Rollen-Bandgießmaschinen vermindern und eine zufriedenstellende Abdichtung ermöglichen.Starting from the aforementioned prior art, the object of the present invention is to provide a method and a device which reduce the technical outlay of previously known sealing elements for the casting gap in two-roll belt casting machines and enable a satisfactory sealing.
Zur Lösung der Aufgabe wird bei einem Verfahren zum Stranggießen eines Metallbandes, im Dickenbereich zwischen 1 und 10 mm, insbesondere einesTo achieve the object, a method for the continuous casting of a metal strip, in the thickness range between 1 and 10 mm, in particular one
Stahlbandes, zwischen zwei nach Art einer umlaufend bewegbaren Kokille im radialen Abstand angeordneten kühlbaren Gießrollen, welche zwischen sich einen Gießspalt begrenzen, wobei die Stirnseiten der Gießrollen anstellbare und/oder einstellbare Abdichtungselemente aufweisen, mit der Erfindung vorgeschlagen, die stirnseitigen Abdichtungselemente entlang einer etwa vertikalen Ebene vorzugsweise in Gießrichtung zu verschieben.Steel strip, between two in the manner of a rotating mold in the radially spaced coolable casting rolls, which delimit a casting gap between them, the end faces of the casting rolls having adjustable and / or adjustable sealing elements, proposed with the invention to preferably move the end sealing elements along an approximately vertical plane in the casting direction.
Damit wird die Lage der stirnseitigen Abdichtungselemente gegenüber den Gießrollen im Gießbetrieb laufend verändert und somit eine mögliche Spaltbildung zwischen Rolle und Seitenabdichtung vermieden. Auf einfache und kostengünstige Weise wird eine Abstandsvergrößerung zwischen den Rollenkan- ten und den feuerfesten Abdichtungselementen unterbunden, und die Produktqualität wird nachhaltig vergleichmäßigt und verbessert.In this way, the position of the sealing elements on the face side in relation to the casting rolls in the casting operation is continuously changed, and a possible gap formation between the roll and the side seal is thus avoided. In a simple and inexpensive manner, an increase in the distance between the roller edges and the refractory sealing elements is prevented, and the product quality is sustainably equalized and improved.
Eine Ausgestaltung des Verfahrens sieht vor, dass die Abdichtungselemente vorzugsweise in Gießrichtung verschoben werden, wobei der Verschiebung eine oszillierende Schwingungen mit im wesentlichen vertikaler Schwingungsrichtung überlagert werden kann.One embodiment of the method provides that the sealing elements are preferably displaced in the casting direction, wherein the displacement can be superimposed on an oscillating oscillation with an essentially vertical direction of oscillation.
Durch die Maßnahme wird die Gefahr eines Festhaftens der schmalseitig anstehenden Schmelze an den Teilen der Dichtungselemente wirksam reduziert.The measure effectively reduces the risk of the melt on the narrow side adhering to the parts of the sealing elements.
Eine weitere Ausgestaltung des Verfahrens sieht vor, dass zur Schwingungserregung Exzenter- oder Hydraulikantriebe verwendet werden.Another embodiment of the method provides that eccentric or hydraulic drives are used to excite vibrations.
Und weiterhin sieht die Erfindung, dass die Schwingungserregung mit einer Frequenz außerhalb der Eigenfrequenz erfolgt. Damit wird ein nachteiliges Aufschaukeln der gesamten Gießvorrichtung verhindert.And the invention further sees that the vibration excitation takes place at a frequency outside the natural frequency. This prevents a disadvantageous rocking of the entire casting device.
Bei einer Vorrichtung zum Stranggießen eines Metallbandes im Dickenbereich zwischen 1 und 10 mm, insbesondere eines Stahlbandes, zwischen zwei nach Art einer umlaufend bewegbaren Kokille im radialen Abstand angeordneten kühlbaren Gießrollen, welche zwischen sich einen Gießspalt begrenzen, wobei die Stirnseiten der Gießrollen in anstellbare und/oder einstellbare Abdichtungselemente aufweisen, sieht die Erfindung vor, dass die stirnseitigen Abdichtungselemente mit Mitteln zum Verschieben relativ quer zu den Achsen der Gießrollen ausgebildet sind.In a device for the continuous casting of a metal strip in the thickness range between 1 and 10 mm, in particular a steel strip, between two coolable casting rolls arranged in the manner of a circumferentially movable mold and which delimit a casting gap between them If the end faces of the casting rolls have adjustable and / or adjustable sealing elements, the invention provides that the front sealing elements are designed with means for displacement relative to the axes of the casting rolls.
Mit Hilfe einer Oszillation der Schmalseiten-Abdichtungselemente wird ein nachteiliges Anhaften der Abdichtungselemente im Bereich der Schmelze an den Stirnseiten des Gießspaltes bzw. der Gießrollen mit unkomplizierten Mitteln vermieden.With the help of an oscillation of the narrow side sealing elements, disadvantageous adherence of the sealing elements in the area of the melt to the end faces of the casting gap or the casting rolls is avoided with uncomplicated means.
Nachfolgend wird die Erfindung anhand einer Zeichnung eines Konstruktionsbeispieles zusätzlich erläutert.The invention is explained in more detail below with reference to a drawing of a construction example.
Die einzige Figur zeigt in Seitenansicht, d. h. in Blickrichtung der Achsen des Gießrollenpaares 6 eine Stranggießanlage für dünne Bänder mit einer Gieß- pfanne 1 , aus welcher über ein Schattenrohr 2 Schmelze in einen Verteiler 3 unter Ausbildung eines konstant gehaltenen Gießspiegels 14 eingeleitet wird.The only figure shows a side view, i. H. In the direction of the axes of the casting roller pair 6, a continuous casting installation for thin strips with a casting ladle 1, from which melt is introduced into a distributor 3 via a shadow pipe 2 to form a casting level 14 which is kept constant.
Aus dem Verteiler 3 wird Schmelze 4 mittels in dessen Richtung angeordneten Tauchrohren 5 in einen Gießraum zwischen dem Gießrollenpaar 6 entlang des Gießspaltes 11 eingeleitet. Aus diesem wird, unter stetiger Bildung sich gleichmäßig aufbauender Strangschalen im Gießspalt 11 , das durcherstarrte Gussprodukt 7, in Form eines dünnen Bandes in Gießrichtung 12 ausgetragen. Die Gießgeschwindigkeit wird nach Maßgabe des Erstarrungsvorganges der Schmelze im Kontakt mit den kühlbaren Oberflächen der Gießrollen 6 in an sich bekannter Weise entsprechend eingestellt.From the distributor 3, melt 4 is introduced into the casting space between the pair of casting rolls 6 along the casting gap 11 by means of dip tubes 5 arranged in the direction thereof. From this, the solidified cast product 7 is discharged in the form of a thin band in the casting direction 12 with the continuous formation of strand shells which build up uniformly in the casting gap 11. The casting speed is adjusted accordingly in accordance with the solidification process of the melt in contact with the coolable surfaces of the casting rollers 6 in a manner known per se.
Zur jeweiligen Seitenabdichtung der Gießrollen und damit auch des Gießspaltes 11 ist das Abdichtungselement 8 vorgesehen, welches gemäß Erfindung mit Mitteln zum Verschieben relativ quer zu den Achsen der Gießrollen 6, in verti- kaier Richtung 10 ausgebildet ist. Dabei hat es sich als besonders vorteilhaft erwiesen, dass die stirnseitigen Schmalseiten-Abdichtungselemente 8 entlang einer etwa vertikalen Ebene in vergleichsweise kurzen reziproken Hüben in eine Art Oszillation versetzt werden.For the respective side sealing of the casting rolls and thus also the casting gap 11, the sealing element 8 is provided, which according to the invention is designed with means for displacing in the vertical direction 10 relative to the axes of the casting rolls 6. It has proven to be particularly advantageous that the short-side sealing elements 8 on the end face are set into a kind of oscillation along a roughly vertical plane in comparatively short reciprocal strokes.
Damit wird auf einfache und kostengünstige Weise eine Spaltbildung bzw. eine Abstandsvergrößerung zwischen den Rollenkanten und der feuerfesten Platte 8 als Abdichtungselement zuverlässig vermieden. Es kann sich dabei um eine im wesentlichen vertikale Schwingungsrichtung handeln.In a simple and cost-effective manner, a gap formation or an increase in the distance between the roll edges and the refractory plate 8 as a sealing element is thus reliably avoided. This can be an essentially vertical direction of oscillation.
Der Antrieb zur Schwingungserregung der Abdichtungselemente 8 kann auf vielfältige Weise erfolgen. Eine vorteilhafte und einfache Lösung ergibt sich, wenn zur Schwingungserregung Exzenter- oder Hydraulikantriebe verwendet werden. Diese sind zuverlässig und vielfach erprobt.The drive for vibrating the sealing elements 8 can take place in a variety of ways. An advantageous and simple solution is obtained if eccentric or hydraulic drives are used to excite vibrations. These are reliable and tried and tested many times.
Dabei ist noch darauf hinzuweisen, dass die Schwingungserregung mit einer Frequenz außerhalb der Eigenfrequenz erfolgen soll, um eine Übertragung der Schwingungen auf sonstige Teile der Anlage zu verhindern. It should also be pointed out that the vibration excitation should take place at a frequency outside the natural frequency in order to prevent the vibrations from being transmitted to other parts of the system.
