Abstract
Description
Die Erfindung betrifft eine Stranggießanlage zum Gießen von Dünnbrammen mit einer elektromagnetischen Bremsvorrichtung für die durch ein Tauchgießrohr in die Kokille einströmende Stahlschmelze, die aus je einer den Kokillenbreitseiten zugeordneten Spule mit einem ferromagnetischen Kern sowie einem die Kokille umschließenden Joch besteht.The invention relates to a continuous caster for casting thin slabs with an electromagnetic braking device for the steel melt flowing through a dip tube into the mold, which consists of a coil associated with the broad sides of the mold with a ferromagnetic core and a yoke enclosing the mold.
Bei einer derartigen, durch die EP-B1 04 01 504 bekannten Stranggießanlage sind den Breitseiten einer Brammenkokille Kerne einer elektromagnetischen Bremsvorrichtung zugeordnet, deren Pole übereinander angeordnet sind. Die Kerne sind zur Beeinflussung der Flussdichte des Magnetfeldes um eine untere Achse schwenkbar. Mit dieser aufwendigen Vorrichtung ist eine Beeinflussung des Magnetfeldes nur in begrenztem Umfang und geringer Genauigkeit durchführbar.In such a continuous casting installation known from EP-B1 04 01 504, the broad sides of a slab mold are assigned cores of an electromagnetic braking device, the poles of which are arranged one above the other. The cores can be pivoted about a lower axis to influence the flux density of the magnetic field. With this complex device, the magnetic field can only be influenced to a limited extent and with low accuracy.
Der Erfindung liegt die Erkenntnis zugrunde, daß sich bei unterschiedlichen Gießprogrammen d.h. unterschiedlichen Gießgeschwindigkeiten, Gießformaten, Stahlqualitäten und Eingießbedingungen unterschiedliche instabile Strömungsverhältnisse innerhalb der Kokille mit der Folge von Qualitätsmängeln einstellen.The invention is based on the knowledge that different casting programs, i.e. different casting speeds, casting formats, steel qualities and casting conditions set different unstable flow conditions within the mold with the consequence of quality defects.
Hiernach ist Aufgabe der Erfindung, die Schaffung einer Stranggießanlage zum Gießen von Dünnbrammen, mit einem engen Kokillenformraum, die aus dem Tauchgießrohr mit hoher Geschwindigkeit ausströmende Schmelze mit einer einfachen kostengünstigen Bremsvorrichtung genauer dem Gießprogramm und den daraus resultierenden Gießbedingungen anzupassen.The object of the invention is to create a continuous casting installation for casting thin slabs with a narrow mold cavity, the melt flowing out of the immersion casting tube at high speed with a simple, inexpensive braking device, more precisely the casting program and the resulting results Adjust casting conditions.
Die gestellte Aufgabe wird nach der Erfindung dadurch gelöst, daß die Kerne aus je einem Hauptkern und einem gießstrangseitigen Teilkern gebildet sind und unterschiedliche Teilkerne zur Anpassung des Magnetfeldes an wechselnde Gießbedingungen wahlweise einsetzbar sind.The stated object is achieved according to the invention in that the cores are each formed from a main core and a partial core on the casting strand side and different partial cores can be used to adapt the magnetic field to changing casting conditions.
Durch die erfindungsgemäße Anpassung des Magnetfeldes an das jeweilige Gießprogramm kann bei wechselnden Gießbedingungen durch definierte Abbremsung der Eingießströmung eine konstante optimale Strömungsverteilung innerhalb der Kokille erzielt werden. Insbesondere werden Strangschalenauswaschung, Gießspiegelwellen, zu einer Mangelschmierung führende örtliche Dickenschwankungen der aufliegeden Schlackenschicht, und ein Einziehen von Schlacke und Gießpulver in den Strang vermieden. Daraus resultiert als Gesamtwirkung eine erhebliche Verbesserung sowohl der Strangoberfläche als auch des Gefüges des gegossenen Dünnbrammenstranges.By adapting the magnetic field to the respective casting program according to the invention, a constant optimal flow distribution within the mold can be achieved with changing casting conditions by defined braking of the pouring flow. In particular, strand shell washing, casting mirror waves, local fluctuations in thickness of the slag layer lying on top, which lead to insufficient lubrication, and drawing in of slag and casting powder into the strand are avoided. The overall effect of this is a considerable improvement in both the strand surface and the structure of the cast thin slab strand.
Zur genaueren Anpassung und Einstellung des Magnetfeldes können die Teilkerne folgender Ausgestaltung verwendet werden:
Die Teilkerne weisen unterschiedliche Längenmaße auf.
Die Teilkerne weisen unterschiedliche Höhenmaße auf.
Die Teilkerne weisen Querschnittsverringerungen auf.
Seitenbereich eines Teilkernes sind gegenüber einem Mittenbereich in der Höhe versetzt.The partial cores of the following configuration can be used for more precise adaptation and adjustment of the magnetic field:
The partial cores have different lengths.
The partial cores have different heights.
The partial cores have reduced cross-sections.
The side area of a partial core is offset in height from a central area.
Gemäß einem weiteren Merkmal der Erfindung befindet sich in einem Kokillenrahmen zur Aufnahme der unterschiedlichen Teilkerne aus magnetischem Werkstoff gießstrangseitig vor einem Hauptkern eine Ausnehmung und in durch Teilkerne unterschiedlicher Abmessung in der Ausnehmung verbleibenden Zwischenräumen sind unmagnetische Füllstücke eingesetzt.According to a further feature of the invention, there is a recess in a mold frame for accommodating the different partial cores made of magnetic material on the casting strand side in front of a main core, and non-magnetic filler pieces are used in the interstices remaining in the recess due to partial cores of different dimensions.
