Description

Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von Fertigprofilen aus Metall mit einem Walzgefüge, insbesondere geometrisch komplexen Profilen wie z. B. Träger, Spundwandbohlen, Eisenbahnschienen und Oberbaumaterial, bei dem ein kontinuierlich gegossener Endlosstrang mit einem Gußgefüge ohne Unterteilung und Zwischenerwärmung einem Walzwerk, insbeondere Universalwalzwerk zugeführt wird. Außerdem betrifft die Erfindung eine Anordnung zum Durchführen des Verfahrens.The invention relates to a process for continuous Manufacture of finished profiles from metal with a Rolled structure, in particular geometrically complex profiles such as e.g. B. beams, sheet piles, railroad tracks and Track material in which a continuously cast Endless strand with a cast structure without subdivision and intermediate heating a rolling mill, especially a universal rolling mill is fed. The invention also relates to a Arrangement for performing the method.

Derartige Verfahren und Anordnungen zu deren Durchführung sind aus dem Stand der Technik bekannt. In Neue Hütte, November 1983, Seiten 424 - 426 ist ein Verfahren zur kontinuierlichen Herstellung von Fertigprofilen beschrieben, bei dem mit Hilfe eines Gießrades ein kontinuierlicher Strang gegossen wird. Nach dem Verlassen der Kokille des Gießrades wird der Strang über mehrere Rollen und einen Richttreiber gerichtet, zur kompletten Erstarrung gebracht und einer Ausgleichstrecke zugeführt, in der die Temperatur über den Flächenquerschnitt des Stranges einheitlich eingestellt wird. Der gegossene Strang hat eine trapezoide Querschnittsform, um ihn problemlos aus der Kokille des Gießrades lösen zu können. In einem Vertikal- und Horizontalgerüst erfolgt eine Umformung des Stranges in eine quadratische Querschnittsform, die dann als kontinuierlicher Strang einer Vorstraße und anschließend der Fertigstraße zugeführt wird, in der aus dem Strang das Fertigprofil hergestellt wird. Such methods and arrangements for their implementation are known from the prior art. In Neue Hütte, November 1983, pages 424-426 is a process for continuous Manufacture of finished profiles described in which cast a continuous strand using a casting wheel becomes. After leaving the mold of the casting wheel the strand is directed over several rollers and a directional driver, brought to complete solidification and an equalizing section supplied in which the temperature across the cross-sectional area of the strand is set uniformly. The cast strand has a trapezoidal cross-sectional shape to it to be able to be easily removed from the mold of the casting wheel. In a vertical and horizontal stand is formed of the strand into a square cross-sectional shape, which then as a continuous strand of a rough road and then is fed to the finishing train, in which the Finished profile is produced.

Im einzelnen besteht die Anlage zur Durchführung dieses Verfahrens aus folgenden, in Richtung des Materialflusses hintereinander angeordneten Bereichen:

  • a) Flüssigstahlbereich: Als Gießmaschine kommt ein Gießrad zum Einsatz. Der in trapezoider Form das Gießrad verlassende Strang wird von einem wassergekühlten Abstreifmeißel. aus dem Rad gehoben und der Biegezone und dem Richttreiber zugeführt.Zur Funktion und Wirkungsweise eines Gießrades zum kontinuierlichen Gießen eines Metallbandes wird beispielhaft auf die DE-A- 1 941 729 hingewiesen.
  • b) Kühl- und Ausgleichszone: An den Gießbereich schließt sich der Kühlbereich an, der als offene Sprühkühlung ausgeführt ist, um den flüssigen Restsumpf im Strang kontrolliert zu verfestigen. Der Kühlung schließt sich eine Ausgleichszone an, die durch einen in der Geschwindigkeit einstellbaren Rollgang realisiert ist, den der Strang ohne zusätzliche Kühlung durchläuft und auf dem ein Wärmeausgleich im Strang stattfindet.
  • c) Walzbereich: Der anschließende Walzbereich besteht aus zwei Walzgerüsten, in denen der Strang auf Abmessung gewalzt wird, die sich in einem weiterverarbeitenden Walzwerk, beispielsweise einer Vorstraße, einsetzen lassen.
    • In detail, the system for carrying out this method consists of the following areas arranged one behind the other in the direction of the material flow:
  • a) Liquid steel area: A casting wheel is used as the casting machine. The strand leaving the casting wheel in a trapezoidal shape is replaced by a water-cooled scraper. Lifted out of the wheel and fed to the bending zone and the straightening driver. For example, reference is made to DE-A-1 941 729 regarding the function and mode of operation of a casting wheel for the continuous casting of a metal strip.
  • b) Cooling and equalization zone: The casting area is followed by the cooling area, which is designed as an open spray cooling system, in order to solidify the residual liquid sump in the strand in a controlled manner. The cooling is followed by a compensation zone, which is realized by a roller table that can be adjusted in speed, which the strand runs through without additional cooling and on which heat compensation takes place in the strand.
  • c) Rolling area: The subsequent rolling area consists of two rolling stands, in which the strand is rolled to dimensions that can be used in a further processing mill, for example a roughing mill.

    • Mit dem bekannten Verfahren zur kontinuierlichen Herstellung von Fertigprofilen wird der bei diskontinuierlichen Verfahren erforderliche Stoßofen entbehrlich. Außerdem werden die Energiekosten beim Betrieb erheblich reduziert. With the known process for continuous production of finished profiles is that of discontinuous processes the necessary pusher furnace can be dispensed with. It also reduces energy costs significantly reduced in operation.

    Ausgehend von diesem Stand der Technik zur Erzeugung geometrisch einfacher Prifile wie Draht liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Anordnung der eingangs erwähnten Art zur Herstellung von insbeondere geometrisch komplexen Profilen wie Träger, Spundwandbohlen, Eisenbahnschienen und Eisenbahnoberbaumaterial etc. mit verbesserter Wirtschaftlichkeit insbesondere durch weniger Betriebsstörungen, höheres Materialausbringen, geringere Energiekosten und geringerem Konstruktionsaufwand vorzuschlagen.Based on this state of the art for generation geometrically simple prifile such as wire is the invention the task underlying a method and an arrangement of type mentioned above for the production of in particular geometrically complex profiles such as beams, sheet piles, Railroad tracks and railway superstructure material etc. with improved economy, in particular through less Malfunctions, higher material output, lower Energy costs and less design effort to propose.

    Diese Aufgabe wird bei einem Verfahren der eingangs erwähnten Art dadurch gelöst, daß der Endlosstrang unmittelbar und kontinuierlich einem mehrgerüstigen Formstahlwalzwerk zugeführt wird. Die nach dem Stand der Technik erforderliche Erwärmung im Walzwerksofen sowie die Umformung des Stranggußstranges in einer Vorstraße des Formstahlwalzwerkes entfällt. Der kontinuierliche Strang wird unmittelbar in dem mehrgerüstigen Formstahlwalzwerk zu dem Fertigprofil umgeformt.This object is achieved in a method of the type mentioned at the beginning Kind solved in that the endless strand immediately and continuously a multi-stand form steel mill is fed. The state of the art required Heating in the rolling mill furnace and the forming of the Continuous casting in a roughing mill of the steel forming mill not applicable. The continuous strand is immediately in the Multi-stand steel forming mill for the finished profile reshaped.

    Wird der Querschnitt des gegossenen Stranges so weit an den Querschnitt des Fertigprofils angenähert, daß sich das Gußgefüge des Stranges in das Walzgefüge des Fertigprofiles bei minimalem Streckgrad des Stranges im Formstahlwalzwerk umwandelt, lassen sich hohe Produktionsleistungen bei geringer Walzgeschwindigkeit in dem Formstahlwalzwerk realisieren. Gegenüber herkömmlichen Reversierwalzwerken liegen die Walzgeschwindigkeiten etwa um den Faktor 7 niedriger. Die geringeren Walzgeschwindigkeiten erhöhen die Arbeits- und Betriebssicherheit und reduzieren die Geräuschentwicklung beim Betrieb einer Anordnung zum Durchführen des Verfahrens. Gleichzeitig wird durch diese Maßnahme die Qualität des Fertigprofils verbessert. If the cross section of the cast strand so far to the Cross section of the finished profile approximates that the cast structure of the strand in the rolling structure of the finished profile converts the minimum degree of stretching of the strand in the shaped steel rolling mill, can produce high production output at low Realize the rolling speed in the steel forming mill. They are compared to conventional reversing rolling mills Rolling speeds are about 7 times lower. The lower rolling speeds increase the work and Operational reliability and reduce noise when operating an arrangement for performing the method. At the same time, the quality of the Finished profile improved.

    Durch Wechseln der Kokille kann der Querschnitt des gegossenen Stranges an eine Vielzahl unterschiedlicher Fertigprofile angenähert werden, wobei sich die vorstehend angegebenen vorteilhaften Wirkungen ergeben. Als weiterer Vorteil aus dem Endlosgießwalzen resultiert, daß während des Walzens nahezu keine Kopfenden und Fußenden mit gefährlichen scharfen Zungen an Steg und Flanschen auftreten. Nach dem Walzen wird das Fertigprofil einer Kühlstrecke zugeführt und anschließend mit Hilfe einer mitlauf enden Unterteilvorrichtung in Abschnitte unterteilt, deren Länge ein Vielfaches der Länge des verkaufsfähig unterteilten Fertigprofils beträgt. Das Endlosgießwalzen ermöglicht sowohl in vorgeschalteten als auch in nachgeordneten Bereichen der Anordnung zum Durchführen des Verfahrens den Einsatz langsam laufender Maschinen, wie insbesondere Bandsägen zum Unterteilen auf Verkaufslängen.The cross section of the cast can be changed by changing the mold Strands to a variety of different finished profiles can be approximated, with those given above have beneficial effects. Another advantage of the Continuous casting rolls result in almost during rolling no head ends and foot ends with dangerous sharp tongues occur on the web and flanges. After rolling it will Finished profile fed to a cooling section and then with With the help of a moving lower part device in sections divided, the length of which is a multiple of the length of the ready-to-sell divided finished profile. The Continuous casting rolls enables both in upstream and also in subordinate areas of the order for Perform the procedure using slow-moving Machines, such as band saws for dividing Sales lengths.

    Vor Unterteilen des Endlosstranges in Abschnitte mit einem Vielfachen der Verkaufslängen muß dieser auf ein Niveau gekühlt werden, was bei deren weiterer Verarbeitung ein Verziehen vermeidet. Dies erfolgt vorzugsweise mit einer Wasser-Luftkühlstrecke.Before dividing the endless strand into sections with a Multiples of the sales length must be at one level to be cooled, which in their further processing Avoids warping. This is preferably done with a Water-air cooling section.

    Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles erläutert.

    Figur 1
    zeigt eine Anordnung zum Durchführen des Verfahrens in schematischer Seitenansicht und Aufsicht.
    The invention is explained below using an exemplary embodiment.
    Figure 1
    shows an arrangement for performing the method in a schematic side view and top view.

    Der links im Bild gezeigte Flüssigstahlbereich besteht aus einer Pfanne 1, einem Tundish 2 sowie einem Gießrad 3. Der unter der Pfanne 1 angeordnete Tundish hat die Aufgabe, den Gießstrahl auf die Kokille des Gießrades 3 auszurichten und dient als Puffer während des Pfannenwechsels. Das ebenfalls an sich bekannte Gießrad 3 umfaßt eine endlose umlaufende Stahlkette, Abstreifmeißel und Reinigungszubehör sowie Kühlmittel. Die Stahlkette verschließt eine Nut etwa auf einem Viertel des Radumfanges des Gießrades 3 und bildet mit dem Rad die Kokille. Der Stahl läuft vom Tundish 2 in die Kokille und erstarrt während der Vierteldrehung des Gießrades 3 soweit, daß sich eine feste Schale gebildet hat.The liquid steel area shown on the left consists of a pan 1, a tundish 2 and a casting wheel 3. The Tundish arranged under pan 1 has the task of Align the pouring jet on the mold of the casting wheel 3 and serves as a buffer during the pan change. That too Casting wheel 3 known per se comprises an endless rotating one Steel chain, scraper and cleaning accessories as well as coolant. The steel chain closes a groove on approximately one Quarter of the wheel circumference of the casting wheel 3 and forms with that Wheel the mold. The steel runs from the Tundish 2 into the mold and solidifies during the quarter turn of the casting wheel 3 so far that a solid shell has formed.

    Dieser teilerstarrte Strang wird in einer nachgeschalteten Anordnung 4 entzundert und unmittelbar mehreren, im Ausführungsbeispiel vier Profilwalzgerüsten 5 zugeführt, die aus dem dünnen endabmessungsnahen Vorprofil der Kokille, das dem Fertigprofil geometrisch ähnlich ist, beispielsweise einen Doppel-T-Träger formen.This partially solidified strand is connected in a downstream Arrangement 4 descaled and immediately several, in the embodiment four roll stands 5 fed out the thin pre-profile of the mold close to the final dimension, which the Finished profile is geometrically similar, for example one Form the double-T beam.

    Angenommen der gegossene Strang hat ein spezifisches Gewicht von 200 kg/m, resultiert bei einem geforderten Streckgrad zur Umwandlung des Gußgefüges des Stranges in das Walzgefüge des Fertigprofils von λ = 4 ein spezifisches Gewicht des Fertigprofiles von 50 kg/m. Unter der Annahme einer hohen Gießgeschwindigkeit von 20 m/min. ergibt sich bei dem gegebenen Streckgrad von λ = 4 eine Walzgeschwindigkeit von 80 m/min. entsprechend 1,3 m/s. Gegenüber den bei herkömmlichen Reversierwalzwerken üblichen 10 m/s ist dies trotz der hohen Gießgeschwindigkeit eine sehr kleine Walzgeschwindigkeit. Unter den beispielhaft vorgegebenen Prozeßdaten ergibt sich bei 6000 Betriebsstunden pro Jahr eine Jahresproduktionsleistung von 1.440.000 Tonnen.Suppose the cast strand has a specific weight of 200 kg / m, results in a required degree of stretching Conversion of the casting structure of the strand into the rolling structure of the Finished profile of λ = 4 a specific weight of the finished profile of 50 kg / m. Assuming a high casting speed of 20 m / min. results from the given Degree of stretching of λ = 4 a rolling speed of 80 m / min. corresponding to 1.3 m / s. Compared to that of conventional reversing rolling mills This is the usual 10 m / s despite the high casting speed a very low rolling speed. Under the process data given by way of example results in 6000 operating hours per year an annual production output of 1,440,000 tons.

    In einer nachgeschalteten Wasser-Luft-Kühlstrecke 6 wird das walzwarme Profil auf Umgebungstemperatur herabgekühlt, wobei mit der Regelung des Kühlverlaufs die Eigenspannungen, die Gefügeausbildung, die Oberflächenbeschaffenheit und die Geradheit des Profils bei der weiteren Abkühlung gezielt beeinflußt werden.In a downstream water-air cooling section 6 that is hot rolled profile cooled down to ambient temperature, whereby with the regulation of the cooling process the residual stresses that Microstructure formation, the surface texture and the Straightness of the profile targeted during further cooling to be influenced.

    Die geringe Walzgeschwindigkeit der Profilwalzgerüste 5 erlaubt das Unterteilen des kontinuierlich hergestellten Fertigprofils mit einer mitlaufenden Säge 7 in Abschnitte, die mit Hilfe einer Querfördereinrichtung 8 mit darin integrierter Streckrichtanlage 9 einer Stapelanlage 10 zum Bilden von ein- oder mehrlagigen Schichten (Pakete) der Abschnitte zugeführt werden. Von der Stapelanlage 10 gelangen die Pakete über einen Rollgang 11 zu einer weiteren Unterteilvorrichtung 12. Die Pakete haben ein Gesamtgewicht von etwa 30 t. Infolgedessen können die Zykluszeiten zum Unterteilen der Abschnitte in verkaufsfertige Fertigprofile in der weiteren Unterteilvorrichtung 12 groß gewählt werden, so daß langsam laufende Maschinen, wie beispielsweise Bandsägen, zum Unterteilen in Frage kommen.The low rolling speed of the roll stands 5 allows dividing the continuously manufactured finished profile with a rotating saw 7 in sections that with the help of a cross conveyor 8 with integrated therein Straightening system 9 of a stacking system 10 for forming single or multi-layer layers (packages) of the sections supplied become. The packages arrive from the stacking system 10 via a roller table 11 to a further lower part device 12. The packages have a total weight of around 30 tons. Consequently can use the cycle times to divide the sections in ready-to-sell finished profiles in the further lower part device 12 large be chosen so that slowly running machines, such as band saws, for dividing come into question.
