Description

Die Erfindung betrifft eine Einrichtung zum Umrühren von metallischen Schmelzen in Stranggießanlagen während des Erstarrungsprozesses mittels eines magnetischen Feldes, das den zwischen Rollen geführten Strang senkrecht zu dessen Bewegungsrichtung durchsetzt.The invention relates to a device for stirring metallic melts in continuous casting plants during the solidification process by means of a magnetic field which passes through the strand guided between rollers perpendicular to its direction of movement.

Bekannte Einrichtungen zum Umrühren von in eine Gießform eingefüllten metallischen Schmelzen beruhen auf dem Prinzip eines rotierenden Magnetfeldes, das von mehrphasig erregten Magneten oder einem mehrpoligen Gleichstrom-Magnetsystem erzeugt wird, dessen Erregerwicklungen in vorgegebener Folge nacheinander ein- und ausgeschaltet werden (DE-PS 307 225).Known devices for stirring metallic melts poured into a casting mold are based on the principle of a rotating magnetic field which is generated by magnets excited in multiple phases or a multi-pole DC magnet system, the excitation windings of which are switched on and off one after the other in a predetermined sequence (DE-PS 307 225 ).

Zur Vermeidung einer Deformation oder eines Abrisses des Stranges im Bereich des noch flüssigen Kerns ist es bekannt, mittels magnetischer Gleichfelder, die den Strang senkrecht zu seiner Bewegungsrichtung durchsetzen, und mittels eines durch die Schmelze in der Bewegungsrichtung des Stranges geleiteten Gleichstromes eine Kraft aufzubauen, die das Gewicht des Stranges zumindest teilweise aufhebt (DE-AS 15 58 224).In order to avoid deformation or tearing of the strand in the area of the still liquid core, it is known to build up a force by means of constant magnetic fields which penetrate the strand perpendicular to its direction of movement and by means of a direct current conducted through the melt in the direction of movement of the strand at least partially lifts the weight of the strand (DE-AS 15 58 224).

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Umrühren von metallischen Schmelzen zu schaffen, die in einfacher Weise in Stranggießanlagen, und zwar auch nachträglich, eingebaut und störungsfrei betrieben werden kann.The invention has for its object to provide a device for stirring metallic melts, which can be installed in continuous casting plants, even afterwards, and operated without problems.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das magnetische Feld ein Gleichfeld ist, das ein ebenfalls senkrecht zur Bewegungsrichtung durch den Strang geleiteter Gleichstrom schneidet, daß das Joch eines das Gleichfeld erzeugenden Elektromagneten auf einer Breitseite des Stranges außerhalb der Führungsrollen angeordnet und die Magnetpole mit je einem mindestens eine der Führungsrollen umgreifenden Polschuh ausgestattet ist, während auf der anderen Breitseite des Stranges ein Rückschlußanker mit entsprechend ausgebildeten Polen angeordnet ist und zur Zuführung des Gleichstromes an die Strangoberfläche andrückbare Kontaktbürsten oder Kontaktwalzen vorgesehen sind.According to the invention, this object is achieved in that the magnetic field is a DC field which cuts a direct current which is likewise passed through the strand perpendicular to the direction of movement, that the yoke of an electromagnet generating the DC field is arranged on a broad side of the strand outside the guide rollers and the magnetic poles is equipped with at least one pole shoe encompassing at least one of the guide rollers, while on the other broad side of the strand a return armature with appropriately designed poles is arranged and contact brushes or contact rollers which can be pressed onto the strand surface are provided for supplying the direct current.

. In dieser Ausführung ist der Raumbedarf der Einrichtung gering, weil die Magnetpole mit Hilfe der Polschuhe durch die engen Zwischenräume zwischen den Führungsrollen bis in unmittelbare Nähe der Strangoberfläche geführt werden können. Infolge der einseitigen Anordnung der Feldspulen brauchen nur auf dieser Seite Strangführungsrollen aus unmagnetischem Material eingesetzt zu werden. Die Gleichstromzufuhr läßt sich zusätzlich noch dadurch verbessern, daß die Kontaktwalzen mit ) einer zahnradartig verzahnten Oberfläche ausgestattet sind. Dadurch wird der störende Einfluß von Zunderschichten oder anderen Verunreinigungen der Strangoberfläche vermieden.. In this embodiment, the space requirement of the device is small because the magnetic poles can be guided through the narrow spaces between the guide rollers up to the immediate vicinity of the strand surface with the aid of the pole shoes. Due to the one-sided arrangement of the field coils, strand guide rollers made of non-magnetic material need only be used on this side. The direct current supply can additionally be improved in that the contact rollers are equipped with a gear-toothed surface are. This prevents the disruptive influence of scale layers or other impurities on the strand surface.

An Band eines in der Zeichnung dargestellten Ausführungsbeispiels wird die Erfindung im folgenden näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.

Es zeigen:

  • Fig. 1 Eine Seitenansicht einer Stranggießanlage mit magnetischer Rühreinrichtung
  • Fig. 2 einen horizontalen Schnitt durch die Anlage in Höhe der Rühreinrichtung und
  • Fig. 3 eine Vorderansicht der Anlage.
Show it:
  • Fig. 1 is a side view of a continuous caster with magnetic stirring device
  • Fig. 2 shows a horizontal section through the system at the level of the stirring device and
  • Fig. 3 is a front view of the system.

In den Figuren sind ein Abschnitt eines aus einer Gießkokille gezogenen Stranges 1, beispielsweise einer Bramme, und den Strang führende Rollen 2 schematisch dargestellt. Außerhalb der Führungsrollen auf der einen Breitseite des Stranges ist ein Elektromagnet 3 mit beispielsweise drei Magnetspulen 4 angeordnet, die aus einer nicht dargestellten Gleichstromquelle gespeist werden und die an eine nicht dargestellte Kühlvorrichtung angeschlossen sein können. Die Pole 5 des i Elektromagneten laufen in Polschuhe 6 aus, die eine der Führungsrollen zangenartig umgreifen und sich bis in unmittelbare Nähe der Strangoberfläche erstrecken. Zweckmäßigerweise sind die im Einflußbereich der Pole liegenden Führungsrollen 2a aus unmagnetischem Ma- ) terial hergestellt. Die von den Polschuhen ausgehenden Magnetfeldlinien können daher unbeeinflußt den Strang, wie in Figur 1 gestrichelt dargestellt, durchsetzen und schließen sich über einen Rückschlußanker 7 mit in gleicher Weise geformten Polschuhen 8 auf der 5 anderen Breitseite des Stranges.In the figures, a section of a strand 1 drawn from a casting mold, for example a slab, and rollers 2 guiding the strand are shown schematically. Outside the guide rollers on one broad side of the strand, an electromagnet 3 is arranged with, for example, three magnetic coils 4, which are fed from a DC power source, not shown, and which can be connected to a cooling device, not shown. The poles 5 of the electromagnet end in pole shoes 6, which grip around one of the guide rollers like pliers and extend into the immediate vicinity of the strand surface. The guide rollers 2a lying in the area of influence of the poles are expediently made of non-magnetic material. The magnetic field lines emanating from the pole pieces can therefore penetrate the strand unaffected, as shown in broken lines in FIG. 1, and close via a yoke armature 7 with pole pieces 8 shaped in the same way on the other 5 broad side of the strand.

Aus Figur 3, die eine Ansicht auf die Breitseite des Stranges und den Elektromagneten darstellt, ist die prinzipielle Anordnung der Gleichstromzuführung zum Strang zu ersehen. Hier sind für jede Polarität z.B. zwei Zuführungselektroden 9, die an die Schmalseiten des Stranges mittels eines Gestänges 10 und beispielsweise einer hydraulischen Vorrichtung 11 gedrückt werden, auf der linken Seite beispielsweise als schleifende Kontaktstücke, insbesondere Kontaktbürsten, und auf der rechten Seite als Walzen oder Rollen mit geriefter Oberfläche, d.h. mit im Querschnitt zahnradartigem Aussehen, gezeichnet. Die Verwendung von gezahnten Walzen oder Rollen bietet den Vorteil, daß Zunderschichten oder sonstige Verunreinigungen der Strangoberflächen durchstoßen werden und sich nicht vor den Stromzuführungswalzen sammeln können. Ferner kann jede der beiden auf.einer Seite des Stranges angeordneten Elektroden unabhängig von der anderen Unebenheiten der Strangoberfläche folgen. Je nach dem Verhältnis der Strangbreite zur Breite des Magnetjoches können die Elektroden auf den Schmalseiten oder auf den zwischen dem Magnetjoch und den Seitenkanten des Stranges verbleibenden Flächen der Breitseiten angeordnet sein.The basic arrangement of the direct current supply to the strand can be seen from FIG. 3, which shows a view of the broad side of the strand and the electromagnet. Here for each polarity e.g. two feed electrodes 9, which are pressed against the narrow sides of the strand by means of a rod 10 and, for example, a hydraulic device 11, on the left side, for example, as sliding contact pieces, in particular contact brushes, and on the right side as rollers or rollers with a serrated surface, i.e. with a gear-like appearance in cross section. The use of toothed rollers or rollers offers the advantage that layers of scale or other impurities on the strand surfaces are pierced and cannot collect in front of the power supply rollers. Furthermore, each of the two electrodes arranged on one side of the strand can follow the surface of the strand independently of the other unevenness. Depending on the ratio of the strand width to the width of the magnet yoke, the electrodes can be arranged on the narrow sides or on the surfaces of the broad sides remaining between the magnet yoke and the side edges of the strand.

Die in der Zeichnung dargestellte Einrichtung ermöglicht in besonders vorteilhafter Weise die Entstehung von ausgeprägten Kraftzentren und kräftefreien Zonen, wie durch die in Figur 3 gestrichelt eingezeichneten Strömungslinien angedeutet. Durch die vertikale Ausdehnung des Hauptströmungsfeldes und die Nebenströmungsfelder, die innerhalb des Hauptströmungsfeldes als Turbulenzen anzusehen sind, wird eine kräftige, großvolumige Durchmischung des noch flüssigen Strangkerns 12 (Fig. 2) erzielt. In der Übergangszone zwischen der Hauptströmung und den Nebenströmungen bilden sich kleinere, die Turbulenzen verstärkende Verwirbelugen. Durch diesee raumlich festliegende und im wesentlichen gleichbleibende Gesamtströmungsfeld bewegt sich der Strang mit der Gießgeschwindigkeit.The device shown in the drawing allows in a particularly advantageous manner the emergence of pronounced force centers and force-free zones, as indicated by the flow lines drawn in dashed lines in FIG. 3. The vertical expansion of the main flow field and the secondary flow fields, which are to be regarded as turbulence within the main flow field, achieve vigorous, large-volume mixing of the still liquid strand core 12 (FIG. 2). In the transition In the zone between the main flow and the secondary flows, smaller turbulences are created which increase the turbulence. The strand moves at the casting speed through this spatially fixed and essentially constant total flow field.

In Stranggießanlagen zur Herstellung von Strängen mit gleichbleibendem oder nur wenig unterschiedlichem Breitenformat ergeben sich keine Schwierigkeiten, die Magnetpole zur Erzielung eines optimalen Gesamtströmungsfeldes anzuordnen und zu gestalten. Besteht jedoch die Möglichkeit, in einer Anlage Stränge mit unterschiedlichem Format, z.B. mit einem im Verhältnis 2:1 veränderbaren Breitenformat, zu gießen, müßte auch der Abstand der Magnetpole von einander geändert werden.In continuous casting plants for the production of strands with a constant or only slightly different width format, there are no difficulties in arranging and designing the magnetic poles in order to achieve an optimal overall flow field. However, it is possible to use strands with different formats, e.g. casting with a width format that can be changed in a ratio of 2: 1, the spacing of the magnetic poles from one another would also have to be changed.

Zur Vermeidung derartiger Änderungen werden vorteilhafterweise der Abstand zwischen Magnetpolen und die Breite der dem Strang zugekehrten Enden der Polschuhe quer zur Bewegungsrichtung des Stranges derart gewählt, daß die Polschuhe bei dem größten Strangformat mit ihrer Gesamtbreite und bei dem kleinsten Strangformat mit einem näherungsweise der Hälfte entsprechenden Teil ihrer Breite im Bereich des flüssigen Strangkerns liegen. Auf diese Weise steht bei dem kleinsten Gießformat noch ein ausreichender Teil der Magnetpole zur Erzielung einer kräftigen Rührwirkung zur Verfügung.To avoid such changes, the distance between the magnetic poles and the width of the ends of the pole shoes facing the strand are selected transversely to the direction of movement of the strand in such a way that the pole shoes with the largest strand format with their total width and with the smallest strand format with an approximately half corresponding part their width lies in the area of the liquid strand core. In this way, with the smallest casting format, a sufficient part of the magnetic poles is still available to achieve a powerful stirring effect.

Wegen des geringeren Schmelzevolumens des kleineren Formates bildet sich eine stärkere Gesamtströmung aus als bei dem größten Format, weil die Hauptströmung und die Nebenströmungen sich gegenseitig intensiver durchsetzen.Because of the smaller melt volume of the smaller format, a stronger overall flow is formed than with the largest format, because the main flow and the secondary flows enforce each other more intensively.
