Beim Herstellen von Profilen durch Stranggießen und anschließendes Walzen auf die endgültige Querschnittsgestalt ist es bekannt, zunächst durch Stranggießen einen Rohling mit etwa rechteckigem Querschnitt herzustellen, diesem Rohling dann in einem ersten Walzgerüst einen der späteren Endgestalt ähnlichen Querschnitt in größerem Maßstab zu geben und anschließend in weiteren Walzdurchgängen den Rohling auf den gewünschten Querschnitt herabzuwalzen. Dadurch, daß der aus der Stranggießkokille kommende Rohling zunächst nur an einigen Oberflächenteilen zur Erzielung einer der Endgestalt ähnlichen Querschnittsgestalt bearbeitet wird, haben nach dem bekannten Verfahren hergestellte Profile, über den Querschnitt gesehen, sehr unterschiedliche Struktur, weil einige Querschnittsteile wesentlich stärker verformt worden sind als andere.When producing profiles by continuous casting and subsequent rolling to the final cross-sectional shape it is known to initially cast a blank with an approximately rectangular cross-section produce, this blank then in a first roll stand one of the later final shape similar To give cross-section on a larger scale and then in further rolling passes the Roll the blank down to the desired cross-section. Because of the fact that from the continuous casting mold coming blank initially only on some surface parts to achieve one of the final shape similar cross-sectional shape is processed, have profiles produced by the known method, Viewed across the cross-section, the structure is very different because some cross-sectional parts are essential have been deformed more than others.

Mit Rücksprüngen versehene Profile durch Stranggießen und anschließendes Walzen in solcher Weise herzustellen, daß das Fertigprodukt über den Querschnitt möglichst gleichmäßig gewalzt ist, ist Aufgabe der Erfindung. Die Erfindung löst diese Aufgabe durch eine Stranggießkokille, die durch solche Bemessung des Kokillenhohlraumes gekennzeichnet ist, daß alle Querschnittsteile des Stranges mindestens die fünffache Stärke des gewalzten Endprofils aufweisen. Besonders vorteilhaft ist die Verwendung einer derartigen Stranggießkokille bei der Herstellung von Doppel-T-Trägerprofilen.Profiles provided with recesses by continuous casting and subsequent rolling in such a way to ensure that the finished product is rolled as evenly as possible over the cross-section is the task the invention. The invention solves this problem by a continuous casting mold, which by such Dimensioning of the mold cavity is characterized in that all cross-sectional parts of the strand at least have five times the thickness of the rolled end profile. The use is particularly advantageous such a continuous casting mold in the production of double-T-beam profiles.

Bei nach der Erfindung hergestellten Trägerprofilen hat sich gezeigt, daß die Struktur über dem Querschnitt des Endproduktes nahezu vollständig gleichmäßig ist. Ein zusätzlicher Vorteil der Erfindung besteht neben der Erzielung eines gleichmäßigen Gefüges darin, daß kostenmäßig das Vorgehen nach der Erfindung günstiger ist als das bekannte Verfahren, weil ein Walzschritt in Fortfall kommt, und zwar derjenige, mit dessen HiMe der beim bekannten Verfahren mit rechteckigem Querschnitt ausgestaltete Stranggießrohling etwa die Querschnittsgestalt des Endproduktes, jedoch mit größeren Abmessungen, erhält.In the case of the support profiles produced according to the invention, it has been shown that the structure over the Cross-section of the end product is almost completely uniform. An additional advantage of the invention consists in achieving a uniform structure in the fact that the procedure is cost-effective according to the invention is more favorable than the known method, because a rolling step is omitted comes, namely the one with whose HiMe that of the known method with a rectangular cross-section designed continuous casting blank approximately the cross-sectional shape of the end product, but with larger dimensions.

Zum Herstellen eines Doppel-T-Trägers verwendet man — wenn der Mittelsteg relativ lang sein soll — eine in F i g. 1 in Draufsicht dargestellte Stranggießkokille. Die Abmessungen des Kokillenhohlraumes sind in den Bereichen A, B und C so gewählt, daß der erhaltene Strang überall mindestens die fünffache Stärke des gewalzten Endprofils aufweist. In F i g. 1 sind mit 10 die Kühlwasserkanäle bezeichnet; einerTo produce a double T-beam, if the central web is to be relatively long, one in FIG. 1 continuous casting mold shown in plan view. The dimensions of the mold cavity are selected in areas A, B and C so that the strand obtained has at least five times the thickness of the rolled end profile everywhere. In Fig. 1, 10 denotes the cooling water channels; one

Strichpunktiert ist bei 12 in Fig. 1 angedeutet, daß die aufeinander zu weisenden Innenwände der Kokille nach unten etwas aufeinander zu laufen, wodurch man eine stets satte Anlage des sich verfestigenden Metalls beim Durchlauf nach unten erreicht.the supply or drainage connection for the cooling water is denoted by 11. It is indicated by dash-dotted lines at 12 in FIG. 1 that the inner walls of the mold, which face one another, converge somewhat towards one another downwards, so that the solidifying metal is always in good contact with one another as it passes downwards.

In F i g. 2 ist in ähnlicher Weise wie in der Dar-Stellung nach F i g. 1 eine Kokille dargestellt, die zur Herstellung eines Doppel-T-Profils mit sehr dicken Querflanschen und einem dünnen und kurzen Steg dient. Die Kokille nach F i g. 3 dient zum Herstellen eines Doppel-T-Profils, dessen einer Quersteg schmaler als der andere ist.In Fig. 2 is in a similar manner to the representation according to FIG. 1 shows a mold that is used for Production of a double-T profile with very thick transverse flanges and a thin and short web serves. The mold according to FIG. 3 is used to produce a double-T profile, one of which is a crosspiece is narrower than the other.
