Description

Die Erfindung betrifft ein Stranggiessverfahren gemäss dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung zum Durchführen des Verfahrens gemäss dem Oberbegriff des Anspruches 6.The invention relates to a continuous casting method according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 6.

Beim Bogen-Stranggiessen von Vorprofilen, insbesondere Doppel-T-Vorprofilen oder Beam Blank-Vorprofilsträngen, welche einen Steg sowie zwei seitliche Flansche aufweisen, ist das Kühlwasser auf der Radius-Innenseite im Vorprofilstrang zwischen den Flanschen gefangen und kann nur entlang des Vorprofilstranges nach unten ablaufen. Das Kühlwasser muss vor dem Brennschneiden des Vorprofilstranges aus dem Innenbogen entfernt werden, damit das Schneiden überhaupt möglich ist. Zusätzlich hat das herablaufende Kühlwasser eine übermässige Kühlung in den Profil-Flanschen zur Folge. Dadurch können beim Richten des Stranges Risse in diesem entstehen. Durch die stärkere Kühlung der Profilinnenseite zieht sich dort das Material stärker als auf der Profilaussenseite zusammen, wodurch sich der Radius verkleinern möchte. Diese Änderung des Radius bewirkt eine zusätzliche Belastung der Führungsrollen auf der Innenseite.When sheet continuous casting of Vorprofilen, especially double-T-Vorprofilen or beam blank Vorprofilsträngen, which have a web and two lateral flanges, the cooling water is trapped on the inside radius in Vorprofilstrang between the flanges and can only along the Vorprofilstranges down expire. The cooling water must be removed from the inner arc prior to flame cutting the Vorprofilstranges, so that the cutting is even possible. In addition, the run-off cooling water results in excessive cooling in the profile flanges. This can cause cracks in the strand during straightening. Due to the stronger cooling of the inside profile of the profile, the material pulls together more than on the outside of the profile the radius wants to shrink. This change in radius causes an additional load on the guide rollers on the inside.

Es ist bekannt, wie beispielsweise in der EP 1 497 056 B1 offenbart, das Kühlwasser im Bereich der bogenförmigen Strangführung des Vorprofilstranges aus dem Innenbogen des Profils abzusaugen oder mittels Druckluft auszublasen. Bei all diesen Methoden ist es schwierig, genügend nahe an den Vorprofilstrang zu kommen, um eine genügend gute Wasserdichtung zu realisieren. Die Verwendung von in den Spalt geblasener Druckluft zur Verbesserung der Dichtung bewirkt eine zusätzliche starke Kühlung, die unerwünscht ist. Die benötigte Druckluftmenge ist zudem für den Betreiber kostspielig.It is well known, as in the EP 1 497 056 B1 disclosed to suck the cooling water in the arcuate strand guide of Vorprofilstranges from the inner arc of the profile or blow out by means of compressed air. In all these methods, it is difficult to get close enough to the pre-profile strand to realize a sufficiently good water seal. The use of blown in the gap compressed air to improve the seal causes additional strong cooling, which is undesirable. The amount of compressed air required is also expensive for the operator.

Die Druckschrift DE-A-101 43 419 bezieht sich auf ein Verfahren und eine Vorrichtung zum Ableiten von Ablaufwasser im Innenbogen einer Beam-Blank-Giessmaschine. Dieses Ablaufwasser wird mittels einer Ableitvorrichtung, welche mit Strahldüsen ausgerüstet ist, angehoben und über die seitlichen Profilränder des Innenbogens in eine Sinterrinne geleitet. Zu diesem Zwecke wird unter Einwirkung energiereicher, gegen die Laufrichtung des Wassers im Innenbogen gerichteter Düsenstrahlen unter Ausbildung eines Staudrucks mittels der Ableitvorrichtung mit den Strahldüsen das Wasser aus dem Innenbogen auf die Seite des Stranges in einen darunter befindliche Sinterrinne geleitet. Nachteilig bei diesem Verfahren ist, dass ein permanent hoher Energieaufwand für die Erzeugung eines ausreichenden Staudruckes notwendig ist.The publication DE-A-101 43 419 refers to a method and a device for draining drainage water in the inner arc of a beam blank casting machine. This drainage water is raised by means of a discharge device, which is equipped with jet nozzles, and passed over the lateral profile edges of the inner arc in a sintering trough. For this purpose, under the influence of high-energy, directed against the running direction of the water in the inner arc jets to form a dynamic pressure by means of the discharge with the jet nozzles, the water is passed from the inner arc on the side of the strand in a sintering channel located underneath. A disadvantage of this method is that a permanently high energy consumption for the generation of sufficient back pressure is necessary.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein wirtschaftlich vorteilhaftes Verfahren der eingangs genannten Art vorzuschlagen sowie eine Vorrichtung zum Durchführen des Verfahrens zu schaffen, mit denen die übermässige Kühlung im Innenbogen des Vorprofilstranges weitgehend vermieden werden kann.The present invention has for its object to provide an economically advantageous method of the type mentioned above and to provide an apparatus for performing the method with which the excessive cooling in the inner arc of Vorprofilstranges can be largely avoided.

Diese Aufgabe wird erfindungsgemäss durch ein Verfahren mit den Merkmalen des Anspruches 1 sowie durch eine Vorrichtung nach Anspruch 6 gelöst.This object is achieved according to the invention by a method having the features of claim 1 and by a device according to claim 6.

Bevorzugte Weitergestaltungen des erfindungsgemässen Verfahrens sowie der erfindungsgemässen Vorrichtung bilden den Gegenstand der abhängigen Ansprüche.Preferred developments of the inventive method and the inventive device form the subject of the dependent claims.

Mit dem erfindungsgemässen Verfahren. und der erfindungsgemässen Vorrichtung kann die durch herablaufendes Kühlwasser verursachte übermässige Kühlung im Innenbogen des Vorprofilstranges weitgehend vermieden werden, wobei lediglich Wasserdüsen eingesetzt werden. Es werden weder zusätzliche Umlenkbleche oder Trichter im Schulterbereich, d.h. zwischen den seitlichen Flanschen und dem Steg des Vorprofils, noch Druckluft benötigt. Somit entfallen auch die damit verbundenen Installationen und Betriebskosten.With the inventive method. and the device according to the invention, the excessive cooling caused in the inner arc of the Vorprofilstranges caused by cooling down water can be largely avoided, with only water nozzles are used. There are no additional baffles or funnels in the shoulder area, i. between the side flanges and the web of the pre-profile, still requires compressed air. This eliminates the associated installations and operating costs.

Die zusätzliche Kühlwirkung durch das Umlenkwasser kann durch die Reduktion des Kühlwassers kompensiert werden. Um die Unterkühlung zu reduzieren, kann erhitztes Umlenkwasser eingesetzt werden.The additional cooling effect by the deflection water can be compensated by the reduction of the cooling water. To reduce the hypothermia, heated diverting water can be used.

Beim erfindungsgemässen Verfahren kann die Kühlung des Vorprofilstranges durch Einstellen der Umlenkwasser-Temperatur vorteilhaft beeinflusst werden.In the method according to the invention, the cooling of the pre-profile strand can be advantageously influenced by adjusting the deflection water temperature.

Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigern:

The invention will be explained in more detail with reference to the drawing. It shows:

Fig.1 zeigt eine Stranggiessanlage 1 mit einer wassergekühlten Kokille 2, aus welcher das flüssige Metall, insbesondere Stahl, unter Schalenbildung als Giessstrang kontinuierlich weggeführt wird. Beim Giessstrang handelt es sich um ein Vorprofil, insbesondere ein Doppel-T-Vorprofil 3, dessen Querschnitt aus Fig. 2 und 3 ersichtlich ist, und der einen Steg 4 sowie zwei seitliche Flansche 5, 6 aufweist. Die Erstarrung einer äusseren, festen Strangschale erfolgt bereits in der Kokille 2 (Primärkühlung). Fig.1 shows a continuous casting plant 1 with a water-cooled mold 2, from which the liquid metal, in particular steel, is continuously led away with shell formation as Giessstrang. The casting strand is a pre-profile, in particular a double-T pre-profile 3, the cross section of Fig. 2 and 3 it can be seen, and a web 4 and two lateral flanges 5, 6 has. The solidification of an outer, solid strand shell takes place already in the mold 2 (primary cooling).

Der aus der Kokille 2 vertikal austretende Vorprofilstrang 3 wird durch eine bogenförmige Strangführung 10 geführt und in die Horizontale gebogen. Von einem Richtaggregat 11 gerichtet gelangt er zu einer Brennschneidmaschine 12. Die Strangführung 10 umfasst mehrere hintereinander angeordnete Strangführungssegmente bzw. Module 10a, 10b (in Fig. 1 sind zwei angedeutet), von denen zumindest das an die Kokille 2 anschliessende erste Segment 10a nebst Führungsrollen 15 Sprühdüsen 16 (Fig. 2) zum Zuführen von Kühlwasser umfasst, mittels denen eine sogenannte Sekundärkühlung des Vorprofilstranges 3 erfolgt.The vertically emerging from the mold 2 Vorprofilstrang 3 is guided by an arcuate strand guide 10 and bent into the horizontal. Directed by a straightening unit 11 it passes to a flame cutting machine 12. The strand guide 10 comprises a plurality of successively arranged strand guide segments or modules 10a, 10b (in Fig. 1 two are indicated), of which at least the first segment 10a adjoining the mold 2, together with guide rollers 15, spray nozzles 16 (FIG. Fig. 2 ) for supplying cooling water, by means of which a so-called secondary cooling of the Vorprofilstranges 3 takes place.

Während von der Aussenseite (von der Stegseite 4a sowie von Flanschteilen 5a, 6a nach Fig.2) des in einem Giessradius erzeugten Vorprofilstranges 3 das Kühlwasser problemlos weg vom Vorprofilstrang 3, nach unten, abfliessen kann, bleibt auf der Innenseite, im durch Stegseite 4i sowie durch Flanschteile 5i, 6i begrenzten Innenbogen des Vorprofilstranges 3 das Kühlwasser gefangen, insbesondere im Übergangsbereich zwischen dem Steg 4 und dem jeweiligen Flansch 5, 6 bzw. Flanschteil 5i, 6i, wie in Fig. 2 angedeutet, und hat die Tendenz nach unten, in Richtung zur Brennschneidmaschine 12 hin, abzulaufen. Um dies zu verhindern, wird erfindungsgemäss - nachdem das Kühlwasser die erwünschte Funktion der Sekundärkühlung erfüllt hat - mittels aus Fig. 3 ersichtlichen Wasserdüsen 21, 22 Umlenkwasser in den Innenbogen des Vorprofilstranges 3 eingespritzt und dabei das Kühlwasser aus dem Innenbogen verdrängt. Das Umlenkwasser erzeugt einen Impuls auf das herunterfliessende Kühlwasser. Die Wasserdüsen 21, 22 sind im wesentlichen auf den Übergang vom Steg 4 zum jeweiligen Flansch 5, 6 gerichtet, so dass das Kühlwasser über die Profil-Flanschen 5, 6 bzw. ihre Flanschteile 5i, 6i umgelenkt und samt Umlenkwasser von einer Auffangvorrichtung 23 aufgefangen und über diese abgeführt wird.While from the outside (from the web side 4a and flange parts 5a, 6a to Fig.2 ) of the Vorprofilstranges 3 produced in a Giessradius easily the cooling water away from the Vorprofilstrang 3, down, can flow, caught on the inside, in the 4i by flange side and by flange 5i, 6i limited inner arc of the Vorprofilstranges 3, the cooling water caught, especially in the transition region between the web 4 and the respective flange 5, 6 or flange 5i, 6i, as in Fig. 2 indicated, and has a tendency downwards, toward the cutting machine 12 down to expire. To prevent this, according to the invention - after the cooling water has fulfilled the desired function of the secondary cooling - means Fig. 3 apparent water nozzles 21, 22 deflecting water injected into the inner arc of the Vorprofilstranges 3 while displacing the cooling water from the inner arc. The deflection water generates an impulse to the cooling water flowing down. The water nozzles 21, 22 are directed substantially to the transition from the web 4 to the respective flange 5, 6, so that the cooling water via the profile flanges 5, 6 or their flange 5i, 6i deflected and collected along with deflection water from a collecting device 23 and is dissipated via this.

Die beiden Wasserdüsen 21, 22 sind vorzugsweise mit einem gemeinsamen Wasseranschluss 20 verbunden. Zum besseren Ausspritzen des Profil-Innenbogens können sie mit Vorteil quer zu den seitlichen Flanschen 5, 6 hin und her beweglich angeordnet sein.The two water nozzles 21, 22 are preferably connected to a common water connection 20. For better ejection of the profile inner bow, they can advantageously be arranged to be movable back and forth transversely to the lateral flanges 5, 6.

Die Wasserdüsen mit dem Umlenkwasser werden mit Vorteil bereits im anfänglichen, im wesentlichen noch vertikalen Bereich der bogenförmigen Strangführung 10 eingesetzt und beispielsweise im Bereich zwischen den beiden ersten Strangführungssegmenten 10a, 10b angeordnet (mit Pfeil A in Fig. 1 angedeutet). Die vorzugsweise in einer gemeinsamen Ebene liegenden Wasserdüsen 21, 22 sind dann unter einem vorgegebenen Winkel zur Bogentangente gerichtet, der der zwischen annähernd 0° und 90° beträgt.The water nozzles with the deflection water are advantageously already used in the initial, substantially still vertical region of the arcuate strand guide 10 and arranged, for example, in the region between the two first strand guide segments 10a, 10b (with arrow A) in Fig. 1 indicated). The preferably lying in a common plane water nozzles 21, 22 are then directed at a predetermined angle to the sheet tangent, which is between approximately 0 ° and 90 °.

Das Umlenkwasser kann auch etwa im mittleren Bereich der bogenförmigen Strangführung 10 unter einem Winkel von ca. 45° zur Bogentangente in den Vorprofilstrang 3 eingeleitet werden.The deflection water can also be introduced into the pre-profile strand 3 at an angle of approximately 45 ° to the arc tangent approximately in the middle region of the arcuate strand guide 10.

Es ist aber auch möglich, die Wasserdüsen 21, 22 etwa im mittleren Bereich der bogenförmigen Strangführung 10 anzuordnen, z. B. nach dem zweiten Strangführungssegment 10b nach der Fig. 1. Das Umlenkwasser wird dann unter einem Winkel zur Bogentangente in den Innenbogen des Vorprofilstranges 3 eingeführt (mit Pfeil B in Fig. 1 angedeutet).But it is also possible to arrange the water nozzles 21, 22 approximately in the central region of the arcuate strand guide 10, z. B. after the second strand guide segment 10b after the Fig. 1 , The deflection water is then introduced at an angle to the arc tangent in the inner arc of the Vorprofilstranges 3 (with arrow B in Fig. 1 indicated).

Selbstverständlich könnten die Wasserdüsen 21, 22 bzw. eine den beiden Wasserdüsen 21, 22 gemeinsame Ebene auch einen zwischen 0° und 90° betragenden Winkel einschliessen.Of course, the water nozzles 21, 22 and the two water nozzles 21, 22 common plane could also enclose an angle between 0 ° and 90 °.

Die beiden auf den Übergang vom Steg 4 zum jeweiligen Flansch 5, 6 des Vorprofilstranges 3 gerichteten Wasserdüsen 21, 22 liegen in einer gemeinsamen Ebene, die mit der Bogentangente den zwischen annähernd 0° und 90° betragenden Winkel einschliesst.The two directed to the transition from the web 4 to the respective flange 5, 6 of the Vorprofilstranges 3 water nozzles 21, 22 lie in a common plane which encloses the arc tangent between approximately 0 ° and 90 ° amounting angle.

Mit dem erfindungsgemässen Verfahren und der erfindungsgemässen Vorrichtung kann die durch herablaufendes Kühlwasser verursachte übermässige Kühlung im Innenbogen des Vorprofilstranges weitgehend vermieden werden, wobei lediglich Wasserdüsen eingesetzt werden. Es werden weder zusätzliche Umlenkbleche oder Trichter im Schulterbereich, d.h. zwischen den seitlichen Flanschen des Vorprofils, noch Druckluft benötigt. Somit entfallen auch die damit verbundenen Installationen und Betriebskosten. Das sowieso in diesem Bereich verwendete Wasser steht kostengünstig zur Verfügung. Die Umlenkvorrichtung befindet sich ausserhalb des Schulterbereiches, und es kann daher keine Kollision zwischen dem Giessstrang und der Umlenkvorrichtung geben.With the method according to the invention and the device according to the invention, the excessive cooling in the inner arc of the pre-profiled strand caused by cooling down water can be largely avoided, only water nozzles being used. Neither additional baffles or funnels in the shoulder area, ie between the lateral flanges of the pre-profile, nor compressed air is required. This eliminates the associated installations and operating costs. The water used anyway in this area is available at low cost. The deflection device is located outside the shoulder region, and therefore there can be no collision between the casting strand and the deflection device.

Die zusätzliche Kühlwirkung durch das Umlenkwasser kann durch die Reduktion des hinunterfliessenden Kühlwassers kompensiert werden. Um die Unterkühlung zu reduzieren, kann erhitztes Umlenkwasser eingesetzt werden.The additional cooling effect by the deflection water can be compensated by the reduction of the downflowing cooling water. To reduce the hypothermia, heated diverting water can be used.

Beim erfindungsgemässen Verfahren kann die Kühlung des Vorprofilstranges durch Einstellen der Umlenkwasser-Temperatur vorteilhaft beeinflusst werden.In the method according to the invention, the cooling of the pre-profile strand can be advantageously influenced by adjusting the deflection water temperature.
