Abstract
Description
Die Erfindung betrifft eine Kokille zum Stranggießen von Metall mit einem gekühlte Breitseiten- und Schmalseitenwände aufweisenden, trichterförmig in Gießrichtung zum Format des gegossenen Stranges verjüngten Eingießbereich.The invention relates to a mold for the continuous casting of metal with a cooled Breitseiten- and narrow side walls having funnel-shaped in the casting direction to the format of the cast strand tapered Eingießbereich.
Die Abmessungen des Eingießbereichs werden im wesentlichen durch den Querschnitt des zu vergießenden Stranges, die Abmessungen des Gießrohres und dessen Eintauchtiefe in die Schmelze bestimmt.The dimensions of the pouring area are determined essentially by the cross section of the strand to be cast, the dimensions of the pouring tube and its immersion depth in the melt.
Aufgrund der trichterförmigen Formgebung der Breitseitenwände findet in Gießrichtung nicht nur eine Verjüngung, sondern auch eine Formänderung des Strangquerschnittes statt. Infolgedessen werden der Strangschale beim Durchlaufen einer Trichterkokille im Gegensatz zu einer herkömmlichen Stranggießkokille mit ebenen Wänden zusätzliche Verformungen aufgezwungen. Um die Entstehung von Oberflächenfehlern des Gußproduktes zu vermeiden, dürfen diese zusätzlichen Verformungen einen bestimmten Grenzwert nicht überschreiten, damit die Strangschale nicht überlastet wird und eine über den Strangquerschnitt gleichmäßige Wärmeabfuhr gewährleistet bleibt.Due to the funnel-shaped shaping of the broad side walls not only a taper, but also a change in shape of the strand cross-section takes place in the casting direction. As a result, in contrast to a conventional continuous casting mold with flat walls, the strand shell is forced through additional deformations when passing through a funnel mold. In order to prevent the formation of surface defects of the cast product, these additional deformations must not exceed a certain limit, so that the strand shell is not overloaded and ensures a uniform over the strand cross-section heat dissipation.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine weitere Trichtergeometrie einer Kokille anzugeben, durch welche Reibung und Verschleiß zwischen Strangschale und Kokillenwänden noch besser vermindert und insbesondere bei der Strangschalenbildung eines zu vergleichsweise hoher Schrumpfung neigenden Stahles eine noch deutlichere Verringerung des Fehlerbefalls der Brammenoberfläche infolge einer möglichst gleichmäßigen Einstellung der Formänderung verwirklicht wird.Based on the aforementioned prior art, the present invention seeks to provide a further funnel geometry of a mold, by which friction and wear between strand shell and mold walls even better reduced and especially in the strand shell formation of a relatively high shrinkage prone steel an even clearer reduction of error the slab surface is realized as a result of a uniform as possible adjustment of the change in shape.
Der Erfindung liegt die Erkenntnis zugrunde, daß im Eingießbereich die durch den Übergang von einem Horizont auf einen darunterliegenden Horizont bedingte Längenänderung der Kokillenkontur auf jedem Horizont ein Maximum aufweist und daß diesem Maximum eine überdurchschnittliche lokale Verformung bzw. verstärkte Neigung zur lokalen Spaltbildung zwischen Strang und Kokillenwand entspricht. Daraus geht hervor, daß der Eingießbereich mindestens ein Maximum der Längenänderung der horizontalen Kokillenkontur aufweist und daß eine möglichst gleichmäßige Verteilung der Formänderung über den Eingießbereich dadurch erzielt wird, daß dieses Maximum möglichst gering ist.The invention is based on the finding that in the pouring region the change in length of the mold contour caused by the transition from a horizon to an underlying horizon has a maximum on each horizon and that this maximum is an above-average local deformation or increased tendency to local gap formation between strand and mold wall equivalent. It follows that the Eingießbereich has at least a maximum of the change in length of the horizontal Kokillenkontur and that the most uniform distribution of the change in shape over the Eingießbereich is achieved in that this maximum is minimized.
Die Aufgabe wird durch eine Kokille gemäß Anspruch 1 und deren Verwendung gemäß Anspruch 7 gelöst.The object is achieved by a mold according to claim 1 and its use according to claim 7.
Die Lösung der Aufgabe gelingt mit der Erfindung dadurch, daß im Trichterbereich die Innenkonturen der Breitseitenwände in Gießrichtung von oben nach unten wenigstens je zwei Punkte mit der Eigenschaft aufweisen, daß sie eine Gerade bestimmen, entlang derer die Innenkonturen dieser Breitseitenwände mit wenigstens einem konkaven und mit wenigstens einem konvexen Abschnitt beliebiger Abfolge ausgebildet sind.The solution of the problem is achieved with the invention in that in the funnel area, the inner contours of the broad side walls in the casting direction from top to bottom at least two points with the property that they determine a straight line along which the inner contours of these broad side walls with at least one concave and are formed at least a convex portion of any sequence.
Erfindungsgemäß wird vorgeschlagen, daß im Trichterbereich die Innenkonturen der Breitseitenwände entlang einer von der Kokillenoberkante bis zur Kokillenunterkante gezogenen Geraden in der Gießrichtung von oben nach unten mit wenigstens einem konkaven Abschnitt und mit wenigstens einem konvexen Abschnitt ausgebildet sind.According to the invention it is proposed that in the funnel area, the inner contours of the broad side walls along a straight line drawn from the upper mold edge to Kokillenunterkante straight in the casting direction from top to bottom are formed with at least one concave portion and at least one convex portion.
Die Lösung der Aufgabe gelingt mit der Erfindung auch dadurch, daß im Trichterbereich die Innenkonturen der Breitseitenwände entlang einer die Kokillenoberkante und den Beginn des unteren vertikalen Abschnitts der Breitseitenwände verbindenden Geraden in Gießrichtung von oben nach unten mit wenigstens einem konkaven Abschnitt und mit wenigstens einem konvexen Abschnitt ausgebildet sind.The object is achieved with the invention also in that in the funnel area, the inner contours of the broad side walls along a top edge and the beginning of the lower vertical portion of the broad side walls connecting straight lines in the casting direction from top to bottom with at least one concave portion and at least one convex portion are formed.
Dabei können mit Vorteil konkave Abschnitte und konvexe Abschnitte der Breitseitenwände unmittelbar ineinander übergehen.Advantageously, concave sections and convex sections of the broad side walls can merge into one another directly.
Vorteilhaft ist auch, dass in Gießrichtung von oben nach unten zuerst der konkave Abschnitt und dann der konvexe Abschnitt bis zum Kokillenaustritt angeordnet sind.It is also advantageous that in the casting direction from top to bottom first of the concave portion and then the convex portion are arranged to Kokillenaustritt.
Dabei kann mit Vorteil jeder der konkaven Abschnitte bzw. der konvexen Abschnitte der Breitseitenwände sowohl eine in deren Verlauf gleichbleibende als auch eine veränderliche Krümmung aufweisen.In this case, each of the concave sections or the convex sections of the broad side walls may advantageously have both a constant as well as a variable curvature in the course thereof.
Eine Ausgestaltung der Erfindung sieht vor, daß die Innenkonturen der Breitseitenwände über die konkaven bzw. über die konvexen Abschnitte einen kreisbogenförmigen Verlauf oder einen trigonometrischen, beispielsweise einen sinusförmigen Verlauf aufweisen.An embodiment of the invention provides that the inner contours of the broad side walls on the concave or on the convex portions have a circular arc shape or a trigonometric, for example, a sinusoidal shape.
Wenn der untere Abschnitt der Kokille einen parallelwandigen Bereich aufweist, wird ein besonders reibungsfreier Übergang zwischen Trichterbereich und anschließendem parallelwandigem Bereich dadurch verwirklicht, daß der untere konvexe oder konkave Bereich mit einem endständigen unteren Kreisbogen in den geradlinigen Bereich mit einem stetigen Verlauf übergeht.When the lower portion of the mold has a parallel-walled portion, a particularly smooth transition between the funnel portion and the subsequent parallel-walled portion is realized by transitioning the lower convex or concave portion with a terminal lower arc into the rectilinear portion with a continuous course.
Eine erfindungswesentliche Ausgestaltung der Trichtergeometrie ergibt sich durch die Maßnahme, daß die Krümmungen der einzelnen Abschnitte der Breitseitenwände mit solchen Radien ausgebildet sind, daß die größte lokale Längenänderung Deltamax (%/m) beim Übergang von einem Horizont auf einen darunterliegenden Horizont den vierfachen Wert der über den Trichterbereich ohne.Berücksichtigung von parallelwandigen Abschnitten gemittelten lokalen Längenänderungen, insbesondere einen Wert von 2,0 %/m nicht übersteigt.An essential feature of the invention funnel geometry results from the measure that the curvatures of the individual sections of the broad side walls are formed with such radii that the largest local change in length delta max (% / m) at the transition from a horizon to an underlying horizon four times the value over the funnel area without taking account of parallel-walled sections averaged local length changes, in particular a value of 2.0% / m does not exceed.
Und schließlich sieht die Erfindung eine Verwendung der beanspruchten Kokille für das Stranggießen von vergleichsweise zu extrem hoher Schrumpfung neigenden peritektischen Kohlenstoffstählen und austenitischen nichtrostenden Stählen vor.Finally, the invention provides a use of the claimed mold for the continuous casting of relatively to extremely high shrinkage prone to peritectic carbon steels and austenitic stainless steels.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung von Längenänderungen der Innenkontur einer Kokille in unterschiedlichen Horizonten des Eingießbereichs durch deren Darstellung in den dreidimensionalen Diagrammen.Further details, features and advantages of the invention will become apparent from the following explanation of changes in length of the inner contour of a mold in different horizons of Eingießbereichs by their representation in the three-dimensional diagrams.
