Abstract

The stream of molten metal in a continuous coating installation is guided and driven by a roller which comprises a core, fitted with journals and a sleeve surrounding the core and fixed to it in the area of the journals. Water circulation pipes are provided between the sleeve and the core; and the part of the core surrounded by the sleeve is subdivided transversely of the axis of the roller. The differences of heat expansion between the core and the sleeve do not impose stresses at their ponits of connection.

Description

Strangführungs- und Treibrolle in einer Stranggießanlage Die Erfindung betrifft eine Strangführungs- und Treibrolle in einer Stranggießanlage, bestehend aus einem Kern und einem diesen umgebenden Mantel, wobei zwischen Mantel und Kern Kühlwasserführungen vorgesehen sind.Strand guide and drive roller in a continuous caster The invention relates to a strand guide and drive roller in a continuous caster, consisting of a core and a jacket surrounding it, with between the jacket and the core Cooling water ducts are provided.

Bei einer bekannten Strangführungs- und Treibrolle ist der Mantel beiderseits mit einem Kern verschweißt. Zwischen Mantel und Kern verlaufen wendelförmig Kühlwasserkanäle, welche an axiale Zuleitungen in den Lagerzapfen angeschlossen sind. Durcn die unterschiedliche Wärmedehnung zwischen Mantel und Kern sowie durch die mechanischen Belastungen werden die Verbindungsstellen vorzeitig zerstört.In a known strand guide and drive roller, the jacket welded to a core on both sides. Between the cladding and the core run helically Cooling water channels, which are connected to axial feed lines in the bearing journal are. Due to the different thermal expansion between the jacket and core as well as through the mechanical loads destroy the joints prematurely.

Es sind bereits Rollen bekannt, bei denen der Mantel auf den Kern aufgeschrumpft ist. Hierbei unterstützt die hohe Schrumpfspannung die Rißbildung im Mantel. Die unterschiedliche Wärmedehnung führt zu einem Wandern des Mantels auf dem Kern. Dadurch entstehen Undichtigkeiten, so daß Kühlwasser austreten kann. Ein weiterer Nachteil ist die aufwendige Herstellung dieser Rollen.There are already known roles in which the jacket on the core has shrunk. The high shrinkage stress supports the formation of cracks in the coat. The different thermal expansion leads to a wandering of the jacket on the core. This creates leaks so that cooling water can escape. Another disadvantage is the complex production of these roles.

Ziel der vorliegenden Erfindung ist eine Mantelrolle, bei der unterschiedliche Wärmedehnungen zwischen Kern und Mantel die Verbindungsstellen nicht belasten. Nach der Erfindung wird dies dadurch erreicht, daß der vom Mantel umschlossene Teil des Kerns quer zur Rollenachse unterteilt ist. Auf diese Weise können sich Wärmedehnungsunterschiede zwischen Mantel und Kern frei ausgleichen, so daß die Verbindung zwischen diesen Teilen nicht belastet wird.The aim of the present invention is a jacket roller, in which different Thermal expansions between the core and the jacket do not stress the connection points. To the invention this is achieved in that the enclosed by the jacket part of the Core is divided transversely to the roll axis. In this way there can be differences in thermal expansion balance freely between the cladding and core, so that the connection between them Sharing is not charged.

Der Kern kann einseitig unterteilt sein, es ist aber auch möglich, den Kern beidseitig zu unterteilen. Durch die Unterteilung des Kerns an den Seiten wird erreicht, daß die Rolle bei einem Riß des Mantels eine begrenzte Zeit funktionsfähig bleibt, da der Kern den Mantel im mittleren, am meisten gefährdeten Bereich stUtzt.The core can be divided on one side, but it is also possible to divide the core on both sides. By dividing the core on the sides it is achieved that the role is functional for a limited time in the event of a rupture of the jacket remains, as the core supports the mantle in the central, most endangered area.

Gemäß einem weiteren Merkmal der Erfindung verlaufen die im Kern vorgesehenen KUhlwasserfUhrungen innerhalb des Mantels Uber alle Teile des Kerns.According to a further feature of the invention, those provided in the core run Cooling water ducts within the mantle over all parts of the core.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: Fig. 1 eine Rolle mit einseitig getrenntem Kern und Fig. 2 eine Rolle mit zweiseitig getrenntem Kern.An exemplary embodiment of the invention is shown in the drawing. The figures show: FIG. 1 a roll with a core separated on one side, and FIG. 2 a roll with core separated on both sides.

Bei der in Figur 1 dargestellten Strangführungsrolle ist ein Mantel 1 beiderseits mit je einem Kernteil 2, 3 verbunden. Jeder Kernteil 2, 3 ist mit einer axialen Kühlwasserzu- bzw. -ableitung 4, 5 versehen, welche an zwischen den Kernteilen 2, 3 und dem Mantel 1 wend4görmig verlaurenden Kühlkanälen angeschlossen sind.In the strand guide roller shown in Figure 1 is a jacket 1 connected on both sides with a core part 2, 3 each. Each core part 2, 3 is with an axial cooling water supply or drainage 4, 5 provided, which at between the Core parts 2, 3 and the jacket 1 connected to helically verlaurenden cooling channels are.

Die Trennstelle 7 zwischen den Kernteilen 2 und 3 ermöglicht den Ausgleich von Dehnungsunterschieden zwischen Mantel und Kern.The separation point 7 between the core parts 2 and 3 enables compensation of expansion differences between the cladding and the core.

Bei der in Fig. 2 dargestellten Rolle ist ein Kern innerhalb eines Mantels 8 beiderseits unterteilt, so daß die Kernteile 9, 10, 11 entstehen.In the role shown in Fig. 2, a core is within a Jacket 8 divided on both sides, so that the core parts 9, 10, 11 arise.
