Description

Die Erfindung betrifft eine Kokille zum Giessen von Doppel-T-Vorprofilen, deren Kokillendurchgang in Fliessrichtung der Schmelze mit einer leichten Konizität versehen ist, wobei die Kokille aus einem einstückigen rohrförmigen Rohling hergestellt ist,.The invention relates to a mold for casting double-T-Vorprofilen whose Kokillendurchgang is provided in the direction of flow of the melt with a slight conicity, wherein the mold is made of a one-piece tubular blank.

Die Konizität des Kokillendurchgangs dient bekanntlich dazu, die innerhalb der Kokille beim Erstarrungsprozess entstehende Schrumpfung des Giessstrangs zu kompensieren. Die Erzeugung dieser Konizität ist insbesondere bei grossformatigen Doppel-T-Vorprofilen bzw. Beam-Blank-Profilen problematisch, weil diese aus einem rohrförmigen Halbzeug im Wesentlichen durch Umformen hergestellt werden und weil solche Profile sehr grosse Abmessungen aufweisen, die über 800 mm Gesamtbreite, über 400 mm Flanschbreite und über 120 mm Stegdicke betragen können. Da mit solch grossen Formaten langsamer gegossen wird als bei kleineren Formaten, benötigt man für sie eine relativ grosse Konizität in der Kokille. Diese Konizität ist aber nur begrenzt bei den herkömmlichen Kokillen erzeugbar, weil deren Kokillendurchgang bekanntlich bei der Umformung mittels eines Stempels hergestellt wird, der als Negativform durch einen rohrförmig ausgebildeten Rohling bzw. Halbzeug gezogen wird. Nach dem bekannten Herstellungsverfahren kann daher jedenfalls nicht bei den queren inneren Seiten des Profils eine Konizität gegen die Kokillenmitte hin erzeugt werden, da es schlicht nicht möglich ist, die verwendete Negativform querschnittsmässig zu verändern.The conicity of Kokillendurchgangs is known to compensate for the resulting shrinkage of the casting within the mold during the solidification process. The generation of this conicity is problematic, especially in large-format double-T pre-profiles or beam-blank profiles, because they are made of a tubular semi-finished material essentially by forming and because such profiles have very large dimensions over 800 mm overall width, about 400 mm flange width and more than 120 mm web thickness. Since casting with such large formats is slower than with smaller formats, it requires a relatively large conicity in the mold. However, this conicity can only be produced to a limited extent in the case of the conventional molds, because their mold pass is known to be produced during the forming by means of a punch, which is drawn as a negative mold through a tubular blank or semi-finished product. In any case, according to the known production method, it is therefore not possible to produce a conicity towards the middle of the mold at the transverse inner sides of the profile, since it is simply not possible to change the negative mold used in cross-section.

Die Druckschrift DE-A-1 282 861 bezieht sich auf eine als Doppel-T-Träger oder ähnlich ausgebildete Stranggiesskokille, die aus mehrteiligen Wänden besteht. Die Innenwände der Kokille laufen nach unten etwas aufeinander zu, wodurch man eine stets satte Anlage des sich verfestigenden Metalls beim Durchlauf nach unten erreicht. Die Innenwände, die parallel bzw. abgerundet parallel zu der Längsmittelachse ange-ordnet sind, laufen aber nicht nach unten aufeinander zu und es wird damit nur eine bedingte Verbesserung beim Vergiessen zu einem Dop-pel-T-Träger erreicht.The publication DE-A-1 282 861 refers to a continuous casting mold designed as a double-T-carrier or similar, which consists of multi-part walls. The inner walls of the mold run down towards each other slightly, whereby one always reaches a whopping plant of the solidifying metal as it passes down. The inner walls, which are arranged parallel or rounded parallel to the longitudinal center axis, but do not run down to each other and it is so that only a conditional improvement in casting to a double-T carrier achieved.

In der Druckschrift US 2006/0278363 ist eine aus einem rohrförmigen Rohling herstellte Kokille geoffenbart, bei welcher es sich um Knüppel- bzw. Vorblockstränge, nicht aber um Doppel-T-Vorprofile handelt. Die Herstellung einer solchen Kokille mit Konizität versehenen Innenwänden ist aufgrund des üblicherweise quadratischen bzw. rechteckigen Querschnittes solcher Kokillen relativ einfach, denn bei quadratischen Quer-schnitten sind alle vier bzw. bei rechteckigen jeweils zwei Innenwände gleich ausgebildet. Zudem bestehen keine Probleme mit dem Zugang zu diesen Innenwänden für die spanabhebende Bearbeitung, da deren Hohlräume ausreichenden Platz für die darin vorzuschiebenden Werkzeuge bieten.In the publication US 2006/0278363 there is disclosed a mold made of a tubular blank, which is billet or billet strands but not double-T billets. The production of such a mold tapered inner walls is relatively simple due to the usually square or rectangular cross section of such molds, because with square cross-sections all four or rectangular in each case two inner walls are the same. In addition, there are no problems with the access to these inner walls for machining because their cavities provide sufficient space for the tools to be advanced there.

Bei einer Stranggiesskokille für ein Doppel-T-Vorprofil gemäss EP-A-0 694 355 ist der Formhohlraum am eingiessseitigen Ende der Kokille entlang des Stegquerschnittes beidseitig mit je einer Querschnittsvergrösserung in der Form einer Stegausbauchung versehen. Mit diesen Stegausbauchungen wird aber nicht eine optimale Kompensation des Schwind-masses der Strangschale erreicht.In a continuous casting mold for a double T-Vorprofil according to EP-A-0 694 355 the mold cavity at the inlet end of the mold along the web cross-section is provided on both sides with a respective cross-sectional enlargement in the form of a web bulge. With these web bulges but not an optimal compensation of the shrinkage mass of the strand shell is achieved.

Der Erfindung liegt die Aufgabe zugrunde, eine Kokille für grossformatige Profile zu schaffen, die zum Giessen grosser T-Vorprofile bzw. Beam-Blank-Formate geeignet ist, weil sie den damit verbundenen giesstechnischen Anforderungen hinsichtlich der Konizität des Kokillendurchganges gerecht wird.The invention has for its object to provide a mold for large-sized profiles, which is suitable for casting large T-Vorprofile or beam-blank formats, because it meets the associated casting requirements with respect to the taper of the Kokillendurchganges.

Diese Aufgabe ist erfindungsgemäss dadurch gelöst, dass sämtliche Innenwände der Kokille im Kokillendurchgang jeweils eine von dieser Ober- zur Unterseite der Kokille in Richtung gegen die Kokillenmitte hin verlaufende Konizität aufweisen.According to the invention, this object is achieved in that all the inner walls of the mold in the mold pass each have a conicity extending from this upper side to the lower side of the mold in the direction of the mold center.

Auf diese Weise ist es insbesondere bei grossformatigen Profilen möglich, den Kokillenquerschnitt optimal dem ebenfalls linearen Schrumpfungsverlauf des Giessstrangs im Bereich des Kokillendurchganges anzupassen. Die spanabhebende Bearbeitung, etwa durch Fräsen, Hobeln oder Polieren, ist an sich Stand der Technik, neu ist aber die erfindungsgemässe Anwendung zur Herstellung der Kokille. Sie ermöglicht die ge-naue Bearbeitung der Innenflächen der Kokille, jeweils in Abhängigkeit von den Abmessungen des zu erzeugenden Profils.In this way, it is possible, in particular for large-format profiles, to optimally adapt the mold cross-section to the likewise linear shrinkage course of the cast strand in the area of the mold pass. The machining, for example by milling, planing or polishing, is in itself state of the art, but new is the inventive application for the production of the mold. It allows the accurate Processing of the inner surfaces of the mold, in each case depending on the dimensions of the profile to be produced.

Der besondere Querschnitt der Beam-Blank-Profile bringt es mit sich, dass der Schrumpfungsgrad des Giessstrangs stark innerhalb des Profilquerschnittes variiert. Zum Beispiel ist er beim relativ schmalen Steg kleiner als in Längsrichtung des Profils. Es ist daher erfindungsgemäss zur Optimierung der Strangbildung vorgesehen, dass jede Innenwand mit einer in Abhängigkeit des Schrumpfungsgrades des Giessstranges individuell bemessenen Konizität versehen ist.The special cross section of the beam blank profiles means that the degree of shrinkage of the casting strand varies greatly within the profile cross section. For example, it is smaller at the relatively narrow web than in the longitudinal direction of the profile. It is therefore provided according to the invention for optimizing the strand formation that each inner wall is provided with a conically dimensioned as a function of the degree of shrinkage of the casting strand.

Die Erfindung sieht ferner vor, dass die Innenwände der Kokille linear, kurvenförmig, gekrümmt, parabolisch oder ähnlich geformt sind.The invention further provides that the inner walls of the mold are linear, curved, curved, parabolic or similarly shaped.

Die in Fig. 1 und Fig. 2 gezeigte herkömmliche Kokille 1 hat einen Kokillendurchgang 2 mit einem Doppel-T-förmigen Querschnitt, entsprechend dem Querschnitt des zu giessenden Profils. Der Kokillendurchgang 2 ist durch die Innenwände 3a bis 3l gebildet. Deren Erzeugung erfolgt mit einem Stempel, der als Negativform durch einen rohrförmigen Rohling gezogen wird. In Fig. 1 ist noch strichliniert das untere Ende der Kokille 1 angedeutet.In the Fig. 1 and Fig. 2 shown conventional mold 1 has a Kokillendurchgang 2 with a double-T-shaped cross section, corresponding to the cross section of the profile to be cast. The mold passage 2 is formed by the inner walls 3a to 3l. Their production takes place with a punch, which is pulled as a negative mold through a tubular blank. In Fig. 1 is still dashed lines the lower end of the mold 1 indicated.

Zum Kompensieren der beim Erstarrungsprozess entstehenden Schrumpfung des Giesstrangs werden die Innenwände 3a bis 3f mit einer Konizität 4 hergestellt. Die queren Innenwände 3i, 3j sowie 3k, 31 dieses Doppel-T weisen dagegen eine Konizität 5 auf, da nur so der Stempel nach der Umformung ausgezogen werden kann.To compensate for the shrinkage of the casting strand during the solidification process, the inner walls 3a to 3f are produced with a taper 4. On the other hand, the transverse inner walls 3i, 3j and 3k, 31 of this double-T have a taper 5, since only then can the punch be pulled out after forming.

Die erfindungsgemässe Kokille 6 nach Fig. 3 bis Fig. 6 unterscheidet sich von der herkömmlichen Kokille 1 im wesentlichen dadurch, dass bei ihr sämtliche Innenwände 7a bis 71 im Kokillendurchgang 8 jeweils eine von dieser Ober- zur Unterseite der Kokille in Richtung gegen die Mitte des Kokillendurchganges hin verlaufende Konizität 9 bis 12 aufweisen.The inventive mold 6 after Fig. 3 to Fig. 6 differs from the conventional mold 1 essentially in that in her all inner walls 7a to 71 in Kokillendurchgang 8 each have from this top to the bottom of the mold in the direction towards the center of Kokillendurchganges extending taper 9 to 12.

Unter Mitte des Kokillendurchganges kann die Mittelachse 1' selbst bzw. die Ebene quer zur Längsausbildung des Kokillenquerschnittes verstanden werden. Streng genommen erfolgt die Erstarrung der Schmelze in der Kokille gegen die Mittelachse hin. Damit man aber nicht noch quer zum Durchgang 2 gesehen nicht lineare Flächen bei diesen Innenwänden vorsehen muss, können sie in dieser Richtung approximiert linear ausgebildet sein. Die Mittelachse kann als Gerade bzw. auch gekrümmt sein, wenn der Kokillendurchgang einen Radius bildet, insbesondere, wenn der gegossene Strang um einen Radius von einer senkrechten in eine horizontale Ebene geführt wird. Der Radius bzw. die Krümmung würde in üblicher Weise senkrecht zur Längsausbildung des Kokillendurchganges verlaufen.The center axis 1 'itself or the plane transverse to the longitudinal formation of the mold cross section can be understood as the center of the mold passage. Strictly speaking, the solidification of the melt takes place in the mold towards the central axis. In order not to have to provide non-linear surfaces in these inner walls when viewed transversely to the passage 2, however, they can be designed to be linear in this direction in an approximated manner. The central axis may be straight as well as curved when the mold passage forms a radius, in particular when the cast strand is guided by a radius from a vertical to a horizontal plane. The radius or the curvature would run perpendicular to the longitudinal formation of the Kokillendurchganges in the usual way.

Vorteilhaft sind die Innenwände 7a bis 7l als gekrümmte Flächen ausgebildet. Sie sind dabei mit einer solchen Krümmung geformt, dass sie der über die Kokillenhöhe nicht linear erfolgenden Erstarrung des darin gegossenen Stranges angepasst sind. So kann es sich zum Beispiel derart verhalten, dass der Strang bereits im oberen Bereich der Kokille schnell erstarrt und danach nurmehr minim schrumpft. Dementsprechend müssten diese Innenwände im oberen Bereich der Kokille bereits um ein verhältnismässig grosses Mass reduziert und im unteren Bereich dann nurmehr minim nach innen verändert werden. Deshalb können sie je nach Bedarf linear, kurvenförmig, gekrümmt, parabolisch oder ähnlich geformt sein.Advantageously, the inner walls 7a to 7l are formed as curved surfaces. They are shaped with such a curvature that they are adapted to the non-linear over the mold height solidification of the strand cast therein. For example, it may behave in such a way that the strand already solidifies rapidly in the upper region of the mold and then only minimally shrinks. Accordingly, would have these inner walls are already reduced by a relatively large amount in the upper region of the mold and then only minimally changed inwards in the lower region. Therefore, they may be linear, curved, curved, parabolic or similarly shaped as needed.

Die Konizität 9 bis 12 der Innenwände 7a bis 7l ist so bemessen, dass sie überall die dort auftretende Schrumpfung kompensiert. Zur Verdeutlichung ist in Fig. 1 bzw. Fig. 3 die Oberseite des Kokillendurchgangs mit ausgezogenen Linien, derweil die Unterseite mit strichpunktierten Linien dargestellt ist. In Fig. 4 ist fernerhin mit dem Pfeil oberhalb der Kokille die Stranggiessrichtung angedeutet.The conicity 9 to 12 of the inner walls 7a to 7l is dimensioned so that it compensates everywhere occurring there shrinkage. For clarification is in Fig. 1 respectively. Fig. 3 the top of Kokillendurchgangs with solid lines, while the bottom is shown with dotted lines. In Fig. 4 Furthermore, the continuous casting direction is indicated by the arrow above the mold.

Die Kokille 6 ermöglicht ein Stranggiessen besonders grossformatiger Profile, weil durch die erfindungsgemässe Bearbeitung des Kokillendurchgangs auch eine entsprechend grosse Konizität erzielbar ist, die zudem dem lokalen Schrumpfungsgrad des Giessstrangs innerhalb des Kokillendurchganges angepasst ist.The mold 6 allows a continuous casting particularly large-sized profiles, because by the inventive processing of Kokillendurchgangs a correspondingly large conicity can be achieved, which is also adapted to the local degree of shrinkage of Gießsstrangs within the Kokillendurchganges.

Die erfindungsgemässe Kokille ist selbstverständlich auch zum Giessen knochenförmiger Profile verwendbar, indem der Kokillendurchgang mit einem entsprechend knochenförmigen Querschnitt versehen ist. Sie eignet sich generell zum Giessen grossformatiger Profile, unabhängig von der Querschnittsgeometrie des zu vergiessenden Profils.Of course, the mold according to the invention can also be used for casting bony profiles by providing the mold passage with a correspondingly bone-shaped cross section. It is generally suitable for casting large-format profiles, regardless of the cross-sectional geometry of the profile to be cast.

Die erfindungsgemässe Ausführung ist ebenfalls zum Instandsetzen oder Überarbeiten benutzter Kokillen verwendbar.The embodiment according to the invention can also be used for repairing or reworking used molds.
