Abstract
Description
Die Erfindung bezieht sich auf eine Bandgiessmaschine zur Erzeugung eines Metallbandes, mit zwei nebeneinander angeordneten, einen Giessspalt bildenden Giessrollen sowie mit Seitenabdichtungen, die beidseits der Giessrollen je eine stirnseitig an die Giessrollen anrückbare Dichtplatte aufweisen, wobei die jeweilige Dichtplatte derart an die beiden Stirnseiten der Giessrollen anrückbar ist, dass mit ihr eine im erwärmten Betriebszustand sehr genaue Auflage an den Stirnseiten der Giessrollen ermöglicht wird.The invention relates to a strip casting machine for production a metal strip, with two side by side, a casting gap forming casters and with side seals on both sides each of the casters has a sealing plate that can be attached to the casters on the front have, the respective sealing plate in such a way to the two The end of the casters can be moved in that one is heated in it Operating condition very precise support on the end faces of the casting rolls is made possible.
Bei einer gattungsmässigen Bandgiessmaschine nach der EP-A-0 714 716 besteht die Einrichtung für die Seitenabdichtung der Giessrollen aus feuerfesten Dichtplatten, die jeweils gegen zwei auf der gleichen Seite befindlichen Stirnseiten der Giessrollen angepresst werden und mit ihnen hierbei verhindert wird, dass die zwischen die Giessrollen eingefüllte Stahlschmelze seitlich wegfliessen kann, sondern wie in einer herkömmlichen Kokille ein Metallbad entsteht. Diese Dichtplatten sind während der Anpressung aufgrund der drehenden Giessrollen einem Reibungsverschleiss ausgesetzt und dies bei einer vom Metallbad entstehenden starken Hitzebelastung. Die Dichtplatten sind mit einer Anpresseinrichtung verbunden, die so konstruiert ist, dass zwangsläufig ein nachteiliges Verschleissbild an den Dichtplatten entsteht. Es bleibt somit eines der Hauptprobleme bei einer solchen Giessmaschine ungelöst, dass die Seitenabdichtungen während der gesamten Giessdauer eine sichere Abdichtung bieten müssen. In a generic strip casting machine according to EP-A-0 714 716 consists of the device for the side sealing of the casting rolls refractory sealing plates, each against two on the same side end faces of the casting rolls are pressed and with them This prevents the one that is filled between the casting rolls Steel melt can flow away to the side, but like in a conventional one Chill creates a metal bath. These sealing plates are during the pressure due to the rotating castors causing frictional wear exposed and this with a arising from the metal bath intense heat. The sealing plates are with a pressure device connected, which is constructed in such a way that an inevitable disadvantage Wear pattern on the sealing plates arises. It remains one of the Main problems with such a casting machine that the Side seals a secure seal during the entire casting time have to offer.
Bei kleineren Giessrollen-Durchmessern zwischen ca. 500 und 800 Millimetern sind entsprechend kleinere Schmalseitenabdichtungen vorzusehen. Aufgrund des kleinen Metallbadvolumens entstehen jedoch unruhige Badspiegeloberflächen. Demgegenüber sind bei Giessrollen mit grösserem Durchmesser, bei ca. 1500 Millimetern, die Badspiegeloberflächen aufgrund des voluminöseren Bades ruhiger, was vorteilhaft ist. Dagegen sind grössere und aufwendigere Seitenabdichtungen erforderlich. Durch Fertigungs- und Montagetoleranzen und unterschiedliche Erwärmung der Giessrollen durch mögliche Ablagerungen ist es möglich, dass die Dichtkanten bzw. Dichtflächen der Rollen zueinander nicht genau in Linie stehen.With smaller cast roller diameters between approx. 500 and 800 millimeters correspondingly smaller narrow side seals must be provided. Due to the small metal bath volume, however, restless ones arise Badspiegeloberflächen. In contrast, with cast rolls Larger diameter, at about 1500 millimeters, the bathroom mirror surfaces quieter due to the more voluminous bath, which is advantageous. In contrast, larger and more complex side seals are required. Through manufacturing and assembly tolerances and different heating of the casting rolls due to possible deposits, it is possible that the sealing edges or sealing surfaces of the rollers do not match each other exactly stand in line.
Aus der japanischen Offenlegungsschrift JP 4-224052 A ist bei einer Bandgiessmaschine mit zwei Giessrollen bekannt, die Reibungskräfte zwischen einer Dichtplatte und den Stirnwänden der Giessrollen zu messen und hiernach die Anpresskräfte auf die Dichtplatte zu ändern. Hierdurch soll unsymmetrischer Verschleiss an der Dichtplatte vermindert werden und die Gefahr von Leckagen von geschmolzenem Metall verhindert werden. Die Anpresskräfte werden über drei Hydraulikzylinder auf die Dichtplatte übertragen. Die Dichtplatte ist starr in einer axialen Richtung in einer Führungshülse geführt, was nachteilig ist.From Japanese laid-open patent publication JP 4-224052 A is in a Belt casting machine with two casting rolls known to the friction forces between a sealing plate and the end walls of the casters and then change the contact pressure on the sealing plate. hereby asymmetrical wear on the sealing plate should be reduced and the risk of leakage of molten metal is prevented become. The contact pressure is exerted by three hydraulic cylinders transfer the sealing plate. The sealing plate is rigid in an axial direction guided in a guide sleeve, which is disadvantageous.
In dem Dokument EP 0 806 997 wird eine Zweiwalzen-Giessanlage beschrieben. Die Dichtplatte für die zwei Giesswalzen besteht aus einem oberen und einem unteren Teil. Der untere Dichtplattenteil wird mit erheblich höherem Druck gegen den Zwickel der Stirnseite der beiden Giesswalzen gepresst als der obere Teil. Der obere Dichtplattenteil wird mittels dreier Zylinder gegen die Walzen gedrückt. Der aufgebrachte Zylinderdruck ist gleichmässig auf alle Zylinder verteilt. Das Verschleissbild der Dichtplatte ist zwangsläufig ungleichmäßig, auch wenn eine sogenannte Federrückführung für den einzelnen Druckzylinder als Rückstellkraft vorgesehen ist. Die Gefahr von Leckagen durch frühzeitigen Verschleiss der Dichtplatten bleibt hoch.A two-roll casting installation is described in document EP 0 806 997. The sealing plate for the two casting rolls consists of one upper and a lower part. The lower sealing plate part becomes significant higher pressure against the gusset on the face of the two Casting rollers pressed as the upper part. The upper sealing plate part will pressed against the rollers by means of three cylinders. The applied cylinder pressure is evenly distributed on all cylinders. The wear pattern the sealing plate is inevitably uneven, even if a so-called Spring return for the individual pressure cylinder as restoring force is provided. The risk of leakage due to premature wear the sealing plate remains high.
Das Dokument EP 0 692 330 B1 befasst sich mit dem Bandgiessen zwischen zwei Giesswalzen, deren Stirnseiten mittels Verschlusswänden abgedichtet sind. Zur permanenten Ermittlung des Berührungszustandes zwischen den Stirnseiten der Walzen und den Verschlusswänden werden die Reibungsbedingungen gemessen und mit vorgegebenen Einstellwerten verglichen. Mit den Vergleichsergebnissen wird wenigstens ein Giessparameter gesteuert. Auch kann die Stellung der Verschlusswand mittels der Grösse der Reibungsbedingungen gesteuert werden. Hierzu ist die Verschlusswand von einer Anordnung gehalten, die an einem in Walzenrichtung verschiebbaren Hauptschlitten und einem Sekundärschlitten besteht, der waagerecht am Hauptschlitten geführt ist. Damit kann die Verschlusswand in zwei Ebenen justiert werden, um den Druck bzw. die Kräfte auf die Verschlusswand in vertikaler und horizontaler Richtung zu messen. Diese Messanordnung beseitigt jedoch nicht die Gefahr von Undichtigkeiten der Verschlusswände infolge ungleichmässigen Verschleisses.Document EP 0 692 330 B1 deals with strip casting between two casting rolls, the end faces of which are by means of sealing walls are sealed. For permanent determination of the state of contact between the end faces of the rollers and the closing walls the friction conditions measured and with specified settings compared. With the comparison results at least one Controlled casting parameters. The position of the closing wall can also controlled by the size of the friction conditions. For this the closure wall is held by an arrangement which is connected to an in Rollable main carriage and a secondary carriage exists, which is guided horizontally on the main slide. In order to the closure wall can be adjusted in two levels to the pressure or the forces on the closure wall in vertical and horizontal To measure direction. However, this measuring arrangement does not eliminate the Danger of leaks in the closing walls due to uneven Wear.

Die Seitenwände sind mit einer Druckplatte und einer Tragplatte verbunden, so dass die Seitenwände in axialer Richtung zu den Giesswalzen und senkrecht zu dieser Richtung beweglich sind. Zwischen Druckplatte und Tragplatte sind mehrere Druckfedern eingefügt, die auf die Seitenwände einwirken. Jede Seitenwand ist von einem gekühlten Ring umgeben. Die Druckplatte wird von einem Wagen getragen, der in axialer Richtung beweglich ist. Auf dem Wagen befindet sich ein Verstellzylinder, der an der Druckplatte angreift. Diese vorbekannte Konstruktion ist jedoch nicht in der Lage, eine ungleichmässige Abnutzung der Seitenwände nachhaltig zu verhindern und die erforderliche Dichtigkeit zwischen Giesswalzen und Seitenwänden über mehrere Giesssequenzen zu gewährleisten.in another document EP 0 698 433 B1 is a double roll continuous casting machine with pressed side walls for continuous casting described thin metal strips.
