Description

Patentanmeldung Stranggußkokille für RohrprofilePatent application for continuous casting mold for pipe profiles

Die Erfindung betrifft eine Stranggußkokille für Rohrprofile.The invention relates to a continuous casting mold for pipe profiles.

Es ist bekannt, beim Herstellen von Rohren im Stranggußverfahren eine Kokille zu verwenden, die aus einem zylindrischen Außenmantel und einem in der Mitte befestigtem Dorn besteht. Dieser Dorn kann durch einen Paßsitz in der Kokille befestigt sein. Es besteht jedoch die Möglichkeit, daß der Dorn während der Produktion in den Ofen zurückwandern kann, weil der Paßsitz, der zur Befestigung dient, durch die hohe Wärmebelastung während des Betriebes zur Befestigung nicht genügt. Es besteht eine andere Möglichkeit, diesen Dorn durch ein Gewinde in der Kokille zu befestigen. Dabei wird der Dorn zwar festgehalten, aber es ist sehr schwierig, dieses Gewinde so herzustellen, daß der Dorn auf jeden Fall zentrisch innerhalb der Kokille angeordnet ist.It is known to use a permanent mold in the manufacture of tubes in the continuous casting process, which consists of a cylindrical outer jacket and a mandrel attached in the middle. This mandrel can be fastened in the mold by a snug fit. However, there is a possibility that the mandrel can migrate back into the furnace during production because the snug fit, which is used for fastening, is not sufficient for fastening due to the high heat load during operation. It exists Another possibility to fix this mandrel by a thread in the mold. While doing this, the thorn is held, but it is very difficult to produce this thread in such a way that the mandrel is definitely centered within the mold is arranged.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden.The invention is based on the object of avoiding these disadvantages.

Die Aufgabe ist dadurch gelöst, daß ein Dorn durch einen zylindrischen Ansatz in einer zylindrischen Aussparung einesThe object is achieved in that a mandrel through a cylindrical Approach in a cylindrical recess of a

Außenmantels in radialer Richtung und durch ein Gewinde in axialer Richtung gehalten wird. Damit ist für einen zentrischen Sitz gesorgt und der Dorn läßt sich nicht ohne weiteres aus der Kokille herausschieben.Outer jacket is held in the radial direction and by a thread in the axial direction. So that's for a centric Seat taken care of and the mandrel cannot be easily pushed out of the mold.

Ein Aueführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert« Es zeigen:An exemplary embodiment of the invention is shown in the drawing and is explained in more detail below.

Fig. 1 einen Querschnitt der Vorrichtung und Fig. 2 eine Ansicht von der Ofenseite her.1 shows a cross section of the device and FIG. 2 shows a view from the furnace side.

Im zylindrischen Außenmantel 1 der Kokille sitzt ein Dorn 2, der durch ein Gewinde 3 mit dem Außenmantel 1 verschraubt ist. Die zentrische Lage des Domes 2 zum Außenmantel 1 wird durch einen kurzen zylindrischen Ansatz k erreicht, der in einer zylindrischen Aussparung 5 mit entsprechenden Durchmesser sitzt. Die Ausfräsungen 6 sind dafür vorgesehen, daß die Schmelze aus dem Ofen ins Innere des Außenmantels 1 eintreten kann.In the cylindrical outer shell 1 of the mold sits a mandrel 2 which is screwed to the outer shell 1 by means of a thread 3. The central position of the dome 2 to the outer jacket 1 is achieved by a short cylindrical extension k , which sits in a cylindrical recess 5 with a corresponding diameter. The cutouts 6 are provided so that the melt can enter the interior of the outer jacket 1 from the furnace.
