Abstract
Description
Die Erfindung betrifft eine Stranggießkokille zum Gießen von Dünnbrammen mit gekühlten Breitseitenwänden und zwischen diesen verstellbar angeordneten, gekühlten Schmalseitenwänden, die einen oberen Formteil und einen unteren Stützteil bilden.The invention relates to a continuous casting mold for casting thin slabs with cooled broad side walls and between these, arranged arranged, cooled narrow side walls, which form an upper molded part and a lower support part.
Bei einer derartigen, durch die DE-A1 41 31 829 bekannten Kokille bilden die gekühlten Breitseitenwände und Schmalseitenwände den oberen Formteil und den die Dünnbramme allseitig bis zum Kokillenausgang umschließenden Stützteil. Der Stützteil wird unten zum Anfahren vom Anfahrkopf verschlossen. Durch Verstellung der Schmalseitenwände kann die gewünschte Breite der Dünnbramme eingestellt werden. Die bekannte Kokille hat den Nachteil, daß es insbesondere beim Gießen mit hohen Gießgeschwindigkeiten zur Rißbildung in den Kanten der Dünnbrammen kommt. Dies führt zur Qualitätsminderung im gewalzten Fertigprodukt.In such a mold known from DE-A1 41 31 829, the cooled broad side walls and narrow side walls form the upper molded part and the support part surrounding the thin slab on all sides up to the mold exit. The support part is closed at the bottom by the start-up head. The desired width of the thin slab can be adjusted by adjusting the narrow side walls. The known mold has the disadvantage that cracks form in the edges of the thin slabs, particularly when casting at high casting speeds. This leads to a reduction in quality in the rolled finished product.
Durch die DE-A2 19 06 261 ist es bei der Gattung der Knüppelkokillen bekannt, 300 - 500 mm unter dem Gießspiegel in der Kokillenwandung Eckenspalte vorzusehen und diese Eckenspalte im Abstand durch wärmedämmende Wandplatten abzudecken. Bei dieser aufwendigen Kokille ist eine Endabdichtung durch den Anfahrkopf äußerst schwierig durchführbar. Eine Formatverstellung ist wegen der starren Verbindung der Wände ausgeschlossen. Die Wärmedämmung der Ecken ist beim Gießen von Dünnbrammen mit hoher Gießgeschwindigkeit nachteilig.From DE-A2 19 06 261 it is known in the billet mold category to provide corner gaps 300-500 mm below the casting level in the mold wall and to cover these corner gaps at a distance by heat-insulating wall panels. With this complex mold, end sealing by the start-up head is extremely difficult to carry out. A format adjustment is impossible due to the rigid connection of the walls. The thermal insulation of the corners is disadvantageous when casting thin slabs at a high casting speed.
Aufgabe der Erfindung ist die Schaffung einer Kokille der angegebenen Gattung, wobei ohne Beeinträchtigung der Formstabilität auf einfache Weise die Bildung von Kantenrissen in der Dünnbramme vermieden wird. Dabei soll eine Verstellung der Schmalseitenwand und eine Abdichtung am unteren Kokillenende möglich sein.The object of the invention is to provide a mold of the type specified, the formation of edge cracks in the in a simple manner without impairing the dimensional stability Thin slab is avoided. An adjustment of the narrow side wall and a seal at the lower end of the mold should be possible.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Schmalseitenwände im Formteil und Stützteil an der inneren Arbeitsseite unterschiedliche Seitenstreifen aufweisen und die Seitenstreifen im Stützteil gegenüber den Seitenstreifen des Formteils nach außen versetzt stehen.This object is achieved according to the invention in that the narrow side walls in the molded part and the support part have different side strips on the inner working side and the side strips in the support part are offset to the outside with respect to the side strips of the molded part.
Durch diese Distanzbildung zwischen der Gießstrangseite und den Seitenstreifen der Schmalseitenwände wird auf einfache Weise eine zu starke beidseitige Abkühlung der Gießstrangkanten und damit eine Rißbildung vermieden. Dabei ist eine Abdichtung der Kokille durch den Anfahrkopf am unteren Ende der Kokille und eine Verstellung der Schmalseitenwände zur Formatverstellung sowie zur Einstellung der Konizität möglich.This formation of distance between the casting strand side and the side strips of the narrow side walls in a simple manner prevents excessive cooling of the casting strand edges on both sides and thus prevents the formation of cracks. It is possible to seal the mold by the start-up head at the lower end of the mold and to adjust the narrow side walls to change the format and to adjust the taper.
Nach einem weiteren Merkmal der Erfindung besteht die Arbeitsseite jeder Schmalseitenwand aus einem ebenen oberen Abschnitt und einem unteren Abschnitt mit abgesenkten Seitenstreifen.According to a further feature of the invention, the working side of each narrow side wall consists of a flat upper section and a lower section with lowered side strips.
Alternativ kann es vorteilhaft sein, daß die Arbeitsseite jeder Schmalseitenwand aus einem oberen Abschnitt mit erhöhten Seitenstreifen und einem ebenen unteren Abschnitt besteht.Alternatively, it can be advantageous that the working side of each narrow side wall consists of an upper section with raised side strips and a flat lower section.
Die Breite der Seitenstreifen beträgt vorteilhaft maximal 15 mm.The width of the side strips is advantageously a maximum of 15 mm.
Die Länge der nach außen versetzten Seitenstreifen im unteren Abschnitt der Schmalseitenwand beträgt maximal 400 mm.The length of the outwardly offset side strips in the lower section of the narrow side wall is a maximum of 400 mm.
Bei alternativer Ausbildung beträgt die Länge der vorstehenden Seitenstreifen im oberen Abschnitt der Schmalseitenwand mindestens 400 mm.In an alternative embodiment, the length of the protruding side strips in the upper section of the narrow side wall is at least 400 mm.

Gemäß den Figuren 1 und 2 besteht eine Kokille zum Gießen von Dünnbrammen aus zwei Breitseitenwänden 1, 2 und zwei seitlich zwischen den Breitseitenwänden 1, 2 verstellbar angeordnete Schmalseitenwänden 3, 4. Die Breitseitenwände 1, 2 sind im Ausführungsbeispiel oben gewölbt und bilden einen erweiterten Eingießbereich 5. Die Breitseitenwände 1, 2 und die Schmalseitenwände 3, 4 sind mit Kühlwasserkanälen 6 versehen.According to FIGS. 1 and 2, a mold for casting thin slabs consists of two
Eine erfindungsgemäße Gestaltung der Arbeitsseite der Schmalseitenwände 3 gemäß Fig. 1, linke Seite, ist in den Figuren 3, 5 und 7 verdeutlicht. Danach bestehen die Schmalseitenwände 3 aus einen oberen Abschnitt 3a mit ebener Arbeitsfläche 3a' und einem unteren Abschnitt 3b. Im unteren Abschnitt 3b fluchtet ein mittlerer Streifen 3b' mit der oberen Arbeitsfläche 3a'. Zwei seitliche Streifen 3b'' sind gegenüber dem mittleren Streifen 3b' vertieft. Ihre Breite ist vorteilhaft geringer als 15 mm.An inventive design of the working side of the
Hierdurch wird erreicht, daß im oberen Teil 3a an den gekühlten Wänden 1, 2, 3a' eine rechteckige Strangschale 7 erstarrt, die bei der Abwärtsbewegung kontinuierlich dicker wird und bis zum unteren Abschnitt 3b selbststützende Kanten ausbildet. Auf diese Weise entsteht an den zurückliegenden Seitenstreifen 3b'' je ein Spalt 8, in dessen Bereich die Kühlung vermindert und die Bildung von Kantenrissen in der gegossenen Dünnbramme vermieden werden.It is hereby achieved that in the
Eine alternative erfindungsgemäße Gestaltung der Arbeitsseite der Schmalseitenwand 4 gemäß Fig. 1, rechte Seite, ist in den Figuren 4, 6 und 8 verdeutlicht. Danach bestehen die Schmalseitenwände 4 aus einem oberen Abschnitt 4a und einem unteren Abschnitt 4b. Der obere Abschnitt 4a weist einen mittleren Streifen 4a' und zwei vorstehendende Seitenstreifen 4a'' auf. Der untere Abschnitt 4b bildet eine mit dem mittleren Streifen 4a' des oberen Abschnitts fluchtende, insgesamt ebene Arbeitsfläche 4b'
Hierbei erstarrt an den Arbeitsflächen 4a', 4a'' des oberen Abschnittes 4a der Schmalseitenwand 4 die in Fig. 4 dargestellte Strangschale 9 mit zurückliegenden Seitenstreifen 9a. Diese bilden, aufgrund der bei fortschreitender Erstarrung wirkenden Selbststützung mit der ebenen Arbeitsfläche 4b' des unteren Abschnitts 4b Spalte 10, durch welche die Kühlung vermindert und Kantenrisse in der gegossenen Dünnbramme vermieden werden.An alternative design according to the invention of the working side of the
