ANMELDETAG: 17. APRIL 1962REGISTRATION DATE: APRIL 17, 1962

BEKANNTMACHUNG DER ANMELDUNG UND AUSGABE DER AUSLEGESCHRIFT: 5. DEZEMBER 1963NOTICE THE REGISTRATION AND ISSUE OF THE EDITORIAL: DECEMBER 5, 1963

Beim Absenken von Einzelsträgen in Stranggießanlagen sind die Absenkwalzen als zylindrische oder profilierte Walzen ausgebildet, die gegen den Strang andrücken. Der Strang muß oberhalb der Absenkwalzen erstarrt sein, da sich an Strängen, die mit flüssigem Kern von den Absenkwalzen gedrückt werden, Quetschrisse bilden. Zur Vermeidung der Innenrisse ist es notwendig, den Abstand zwischen Kokille und Absenkwaken so groß zu bemessen, daß bei gegebenen Absenkgeschwindigkeiten die Sumpfspitze oberhalb der Absenkwalzen liegt. Man kann auch die Absenkgeschwindigkeit niedrig halten, um eine genügend lange Erstarrungszeit zu erreichen. Außerdem werden durch den Anpreßdruck der Absenkwalzen die Stränge um etwa 2 bis 4 mm verformt, was sich vor allem beiRundsträngen ungünstig auswirkt, da sie unrund bzw. oval werden.When lowering individual stretches in continuous casting plants the lowering rollers are designed as cylindrical or profiled rollers, which against the Press the strand on. The strand must be solidified above the lowering rollers, as there are strands that are pressed by the lowering rollers with a liquid core, forming crush cracks. To avoid the Inside cracks it is necessary to dimension the distance between the mold and the sinking hook so large that at given lowering speeds, the sump tip is above the lowering rollers. One can also keep the lowering speed low in order to achieve a sufficiently long solidification time. In addition, the strands are deformed by about 2 to 4 mm due to the pressure of the lowering rollers, which is particularly unfavorable with round strands, as they become out of round or oval.

Diese Nachteile treten auch bei den herkömmlichen Einrichtungen zum Abziehen von Mehrfachsträngen, d. h. bei Strängen vorzugsweise gleichen Formats, welche in derselben Kokille vergossen werden und mit Stegen verbunden sind und nach dem Erstarren mit Hilfe behebiger Vorrichtungen getrennt werden, auf.These disadvantages also occur with the conventional devices for pulling off multiple strands, d. H. in the case of strands, preferably of the same format, which are cast in the same mold and are connected with webs and separated after solidification with the help of remedial devices be on.

Gemäß der Erfindung werden diese Mängel vermieden, indem der Anpreßdruck nur auf die Verbindungsstege zwischen den Einzelsträngen des Verbundstranges ausgeübt wird.According to the invention, these deficiencies are avoided by the contact pressure only on the connecting webs is exercised between the individual strands of the composite strand.

Der wesentliche Vorteil der Erfindung liegt darin, daß die Anordnung der Transportrollen von der Lage der Sumpfspitze des Stranges unabhängig wird. Sie können oberhalb der Sumpf spitze zur Kokille hin angeordnet werden, ohne die Gefahr der Quetschrisse im Strang hervorzurufen, und verkürzen damit gleichzeitig die Bauhöhe der Anlage ganz wesentlich.The main advantage of the invention is that the arrangement of the transport rollers depends on the location the sump tip of the strand becomes independent. You can tip to the mold above the sump be arranged without causing the risk of crushing cracks in the strand, and thus shorten at the same time the overall height of the system is very important.

In der Zeichnung ist eine Anordnung zur Ausführung des Verfahrens dargestellt.The drawing shows an arrangement for carrying out the method.

Die Stege 1 des Mehrfachstranges 2 werden durch Walzenringe 3 erfaßt. Die Walzenringe 3 sind auf dem Walzenkörper 6 mit Paßfedern kraftschlüssig verbunden. Zur Verstellung der Walzenringe 3 auf Verfahren und Einrichtung zum Absenken
eines durch Stege vefbundenen Mehrfachstranges beim StranggießenThe webs 1 of the multiple strand 2 are grasped by roller rings 3. The roller rings 3 are non-positively connected to the roller body 6 with parallel keys. To adjust the roller rings 3 on the method and device for lowering
a multiple strand connected by webs in continuous casting

verschiedene Formate bzw. Stegabstände sind diese Walzenringe mit Distanzringen 7 und Klemmringen 5 zur Aufnahme der Axialkräfte auf den Walzenkörper 6 aufgesetzt. Der Walzenkörper 6 kann natürlich auch als Keilwelle ausgebildet sein.These roller rings with spacer rings 7 and clamping rings 5 are different formats or web spacings placed on the roller body 6 to absorb the axial forces. The roller body 6 can of course can also be designed as a spline shaft.
