Abstract

Die vorliegende Erfindung betrifft eine Durchlaufkokille (1) zum Stranggießen eines Strangs, aufweisend
- ein Innenrohr (2), das einen entlang einer Längsachse (3) beidseitig offenen Formhohlraum (4) ausbildet;
- mehrere Kühlschlitze (5) in zumindest einer äußeren Mantelfläche des Innenrohrs (2), die sich über einen Längenbereich (6) des Innenrohrs (2) parallel zur Längsachse (3) erstrecken;
- eine Manschette (7), die mehrere Kühlschlitze (5) in der Mantelfläche des Innenrohrs (2) quer zur Längsachse (3) umschließt, sodass ein Kühlfluid in einem Kühlschlitz (5) zwischen dem Innenrohr (2) und der Manschette (7) strömen kann; und

ein Außenrohr (8), das das Innenrohr (2) und die Manschette (7) umschließt und fluiddicht abdichtet, sodass sich zwischen dem Innenrohr (2) und dem Außenrohr (8) ein Kühlmantel ausbilden kann. Die Aufgabe der Erfindung ist es, eine Durchlaufkokille (1) zu schaffen, die eine höhere Kühlleistung zulässt und bei der die Kokille (1) eine hohe Steifigkeit aufweist. Diese Aufgabe wird durch eine Durchlaufkokille gelöst, bei der die Manschette (7) das Innenrohr (2) in einer Normalebene zur Längsachse (3) vollständig umschließt, und die Manschette (7) durch Fügen mit dem Innenrohr (2) verbunden ist.

The present invention relates to a continuous casting mold (1) for continuous casting of a strand, comprising
- An inner tube (2) which forms a along a longitudinal axis (3) open on both sides mold cavity (4);
- A plurality of cooling slots (5) in at least one outer circumferential surface of the inner tube (2) extending over a longitudinal region (6) of the inner tube (2) parallel to the longitudinal axis (3) extend;
- A sleeve (7) which encloses a plurality of cooling slots (5) in the lateral surface of the inner tube (2) transversely to the longitudinal axis (3), so that a cooling fluid in a cooling slot (5) between the inner tube (2) and the sleeve (7) can flow; and

an outer tube (8) which surrounds the inner tube (2) and the sleeve (7) and seals fluid-tight, so that a cooling jacket can form between the inner tube (2) and the outer tube (8). The object of the invention is to provide a continuous casting mold (1) which allows a higher cooling capacity and in which the mold (1) has a high rigidity. This object is achieved by a continuous casting mold, in which the sleeve (7) completely encloses the inner tube (2) in a normal plane to the longitudinal axis (3), and the collar (7) is connected by joining with the inner tube (2).
