Abstract

Bei einer aus Breitseitenwänden (1, 2) und Schmalseitenwänden (3, 4) bestehenden Kokille bilden die Breitseitenwände (1, 2) einen oberen trichterförmigen Eingießbereich (9). Zur Schaffung einer funktionsfähigen und betriebssicheren Kokille zum wirtschaftlichen Gießen von Stahlbändern mit fehlerfreiem Gefüge und hoher Oberflächengüte verlaufen die Breitseitenwände (1, 2) seitlich des trichterförmigen Eingießbereichs (9) in einem der Banddicke (d) entsprechenden Abstand parallel bis zu der jeweiligen Schmalseitenwand(3, 4).In the case of a mold consisting of broad side walls (1, 2) and narrow side walls (3, 4), the wide side walls (1, 2) form an upper funnel-shaped pouring area (9). In order to create a functional and reliable mold for the economical casting of steel strips with a defect-free structure and high surface quality, the broad side walls (1, 2) run parallel to the respective narrow side wall (3 , 4).

Description

Kokille zum Stranggießen von StahlbandMold for the continuous casting of steel strip

Die Erfindung betrifft eine Kokille zum Stranggießen von Stahlband, mit gekühlten Breitseitenwänden und Schmalseitenwänden, wobei die Breitseitenwände einen trichterförmigen Eingießbereich bilden, der zu den Schmalseiten und in Gießrichtung auf das Format des gegossenen Bandes reduziert ist.The invention relates to a mold for the continuous casting of steel strip, with cooled broad side walls and narrow side walls, the wide side walls forming a funnel-shaped pouring area, which is reduced to the narrow sides and in the casting direction to the format of the cast strip.

Diese bekannte Kokille (DE-PS 887 990) konnte nicht realisiert werden, da die sich im trichterförmigen Bereich bildende Strangschale beim Ausfördern in der Kokille verklemmt, was zum Abreißen der Strangschale führt.This known mold (DE-PS 887 990) could not be realized, since the strand shell which forms in the funnel-shaped region jams in the mold when it is being conveyed out, which leads to the strand shell being torn off.

Hiernach ist Aufgabe der Erfindung die Schaffung einer funktionsfähigen und betriebssicheren Kokille zum wirtschaftlichen Gießen von Stahlbändern mit fehlerfreiem Gefüge und hoher Oberflächengüte. Weiterhin soll eine Breitenveränderung des Gießformats ermöglicht werden.Accordingly, it is the object of the invention to create a functional and reliable mold for the economical casting of steel strips with a defect-free structure and high surface quality. Furthermore, the width of the casting format should be changed.

Der Erfindung liegt die Erkenntnis zugrunde, daß bei der bekannten Kokillenform die Strangschale im Bereich der Schmalseitenwände trapezförmig erstarrt. Dies führt infolge der Kokillenverengung zum Verklemmen des Stranges.The invention is based on the finding that, in the known mold shape, the strand shell solidifies in a trapezoidal manner in the region of the narrow side walls. As a result of the mold narrowing, this leads to the strand becoming jammed.

Erfindungsgemäß wird daher vorgeschlagen, daß die Breitseitenwände seitlich des trichterförmigen Eingießbereichs in einem der Banddicke entsprechenden Abstand parallel bis zu der jeweiligen Schmalseitenwand verlaufen.It is therefore proposed according to the invention that the broad side walls run parallel to the respective narrow side wall at a distance corresponding to the strip thickness, to the side of the funnel-shaped pouring area.

Dadurch wird ein trapezförmiges Erstarren im Bereich der geneigten Breitseitenwände vermieden. Die Strangschalenbildung im Parallelbereich kann nicht zum Verklemmen führen. EineThis avoids trapezoidal solidification in the area of the inclined broad side walls. The formation of strands in the parallel area cannot lead to jamming. A

Breitenveränderung ist durch Verstellen der Schmalseitenwände auch während des Gießens möglich.The width can also be changed by adjusting the narrow side walls during casting.

Die Breite des Parallelbereichs der Breitseitenwände entspricht vorteilhaft mindestens der Dicke des Gießbandes.The width of the parallel region of the broad side walls advantageously corresponds at least to the thickness of the casting belt.

Die Strangschale unterliegt bei der Reduzierung des trichterförmigen Eingießbereichs auf das Rechteckformat einer Biegebeanspruchung, die proportional zu den in horizontaler bzw. vertikaler Richtung gemessenen Umformwinkeln α der Breitseitenwände ist. Zur Begrenzung dieser Beanspruchung ist der Eingießbereich gemäß einem weiteren Merkmal der Erfindung derart gestaltet, daß die Umformwinkel<< kleiner als 10° sind. Dabei kann der Eingießbereich ganz oder teilweise bogenförmig gestaltet sein.When the funnel-shaped pouring area is reduced to the rectangular format, the strand shell is subjected to a bending stress which is proportional to the forming angles α of the broad side walls measured in the horizontal or vertical direction. To limit this stress, the pouring area is designed in accordance with a further feature of the invention in such a way that the forming angles << are less than 10 °. The pouring area can be designed in whole or in part in an arc shape.

Den Breitseitenwänden kann im Parallelbereich eine besondere Schmierung zugeordnet sein.A special lubrication can be assigned to the broad side walls in the parallel area.

Die Kokillenwände können im oberen Bereich eine geringere Wärmeleitfähigkeit und eine größere Hitzebeständigkeit aufweisen als im unteren Bereich.The mold walls can have lower thermal conductivity and greater heat resistance in the upper area than in the lower area.

Die Kokillenwände können aber auch insgesamt aus einem Werkstoff mit einer Wärmeleitfähigkeit von höchstens 50% der des Kokillenkupfers bestehen.However, the mold walls can also consist of a material with a thermal conductivity of at most 50% of that of the mold copper.

Die Schmalseitenwände können zur Veränderung der Formatbreite im Parallelbereich der Breitseitenwände verstellbar sein.The narrow side walls can be adjustable to change the format width in the parallel area of the wide side walls.

Der Kokille ist ein Oszillationsantrieb und eine Oszillationsführung zugeordnet.The mold is assigned an oscillation drive and an oscillation guide.

Bei einem Verfahren zum Gießen von Stahlbändern unterhalb 60 mm Dicke mit einer erfindungsgemäßen Kokille sind Abkühlgeschwindigkeit und Abzugsgeschwindigkeit derart bemessen, daß die Strangschale am Ende des trichterförmigen Eingießbereichs dünner als 6 mm ist, wobei die Abzugsgeschwindigkeit mindestens 3 m/min vorzugsweise 4-6 m/min beträgt.In a method for casting steel strips with a thickness of less than 60 mm with a mold according to the invention, the cooling speed and the take-off speed are dimensioned such that the strand shell is thinner than 6 mm at the end of the funnel-shaped pouring area, the take-off speed being at least 3 m / min, preferably 4-6 m / min is.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:

  • Fig. 1 die Draufsicht einer Stranggießkokille für Stahlbänder,
  • Fig. 2 einen Längsschnitt im Bereich der Trennfuge zwischen der vorderen Breitseitenwand und den Schmalseitenwänden,
  • Fig. 3 einen Querschnitt durch die leere Kokille,
  • Fig. 4 eine trapezförmig erstarrende Bandkante

und
  • Fig. 5 eine rechteckförmig erstarrende Bandkante.
In the drawing, an embodiment of the invention is shown. Show it:
  • 1 is a top view of a continuous casting mold for steel strips,
  • 2 shows a longitudinal section in the region of the parting line between the front broad side wall and the narrow side walls,
  • 3 shows a cross section through the empty mold,
  • Fig. 4 is a trapezoidal solidifying band edge

and
  • Fig. 5 is a rectangular solidifying band edge.

Bei der dargestellten Stranggießkokille bilden zwei gegenüberliegende Breitseitenwände 1, 2 und zwei zwischen parallelen Seitenbereichen der Breitseitenwände 1, 2 angeordnete Schmalseitenwände 3, 4 den Formraum. Zur Kühlung der Breitgeitenwände 1, 2 sind diese mit Hohlräumen 5 versehen, denen Kühlmittelzu-und ableitungen 6, 7 zugeordnet sind. Die ebenfalls gekühlten Schmalseitenwände 3, 4 sind durch Spindeln 8 zwischen den Breitseitenwänden 1, 2 verstellbar. Eine Oszillationsvorrichtung ist durch Pfeile 13 angedeutet.In the continuous casting mold shown, two opposite broad side walls 1, 2 and two narrow side walls 3, 4 arranged between parallel side regions of the wide side walls 1, 2 form the molding space. To cool the wide side walls 1, 2, they are provided with cavities 5, to which coolant supply and discharge lines 6, 7 are assigned. The narrow side walls 3, 4, which are also cooled, can be adjusted by means of spindles 8 between the wide side walls 1, 2. An oscillation device is indicated by arrows 13.

Die Breitseitenwände 1, 2 formen zu ihrer Mitte einen trichterförmig erweiterten Eingießbereich 9 in den ein den flüssigen Stahl 11 einleitendes Gießrohr 10 hineinragt. Der erfindungsgemäße, aus Fig. 1 ersichtliche Formraum bewirkt eine aus Fig. 5 ersichtliche rechteckige Erstarrung der Strangschale 12 an den Bandseitenkanten, bei der die Nachteile einer in Fig. 4 dargestellten trapezförmig erstarrenden Strangschale 12' vermieden sind. Der Eingießbereich reduziert sich auf die Dicke d des gegossenen Bandes.The broad side walls 1, 2 form a funnel-shaped pouring region 9 into the center thereof, into which a pouring tube 10, which introduces the liquid steel 11, projects. The mold space according to the invention, which can be seen in FIG. 1, causes the strand shell 12 to solidify at the strip side edges, as can be seen in FIG. 5, in which the disadvantages of a trapezoidal solidifying strand shell 12 'shown in FIG. 4 are avoided. The pouring area is reduced to the thickness d of the cast strip.

Die im Eingießbereich erstarrende Strangschale 12 wird beim Ausfördern bei der Reduzierung auf die Banddicke d verformt. Um die daraus resultierenden Biegedehnungen der Strangschale 12 gering zu halten. sind alle für die Verformungen maßgebenden Winkel oC des Eingießbereichs kleiner als 10°.The strand shell 12, which solidifies in the pouring area, is deformed when it is conveyed out when it is reduced to the strip thickness d. In order to keep the resulting bending strains of the strand shell 12 low. all angles oC of the pouring area that are decisive for the deformations are less than 10 °.
