"Traneportwalsen für Stranggießanlagen""Traneportwalsen for continuous casting plants"

Die Erfindung besieht sich auf die Ausbildung und Anordnung der Traneportwalsen in Stranggießanlagen.The invention relates to the training and arrangement of the Traneportwalsen in continuous casting plants.

Es ist bekannt, beim Stranggießen τοη Eisen und Stahl die sum Transport des Stranges notwendigen Waisen unterhalb der Spltse des flüssigen Kernes ansuordnen· Es soll dadurch erreicht werden, daß die durch den notwendigen Anpreßdruck der Waisen an den Strang auftretenden Strangdeformationen nicht su Stranginnenfehlern führen. Aus dem gleichen Grunde ist es bekannt, die den Traneportwalsen Torgeschalteten Stutsrollen drucklos an den Strang angreifen su lassen.It is known that in continuous casting τοη iron and steel the sum To arrange the transport of the strand necessary orphans below the splice of the liquid core It should be achieved that the strand deformations that occur as a result of the necessary contact pressure of the orphans on the strand do not result in internal strand defects to lead. For the same reason it is known to depressurise the port rollers that are gate-switched to the Traneportwalsen to attack the strand su let.

Es ist ferner bekannt (österr. Patentschrift 187 251)» but ?ermeidung τοη Fehlstellen im Kern des Stranges, die durch ungleichmäßige AbkühlungSTerhaltnisee herbeigeführt werden kennen, die Transportwaisen im Bereich des flüssigen Sumpfes ansuordnen und die Waisen eine derartige Verformungearbelt ausführen su lassen, daß die erstarrten Randschichten gegeneinander gepreßt werden. Durch diese Maßnahmen wird das flüssige Metall aus der Sumpfepltse nach oben Terdrlngt und der Strang in seiner AbmessungIt is also known (Austrian Patent 187 251) "but? Avoidance τοη flaws in the core of the strand that are brought about by uneven cooling Arrange transport orphans in the area of the liquid swamp and let the orphans carry out such deformation arbelt, that the solidified edge layers are pressed against each other. These measures remove the liquid metal from the sump to the top Terdrlngt and the strand in its dimensions

Terringert. Eine Verformung der erstarrten Raifkchichten im Sinne einer Streckung des Stranges soll dabei vermieden werden.Terringert. A deformation of the solidified Raifk layers in the A stretching of the strand should be avoided.

Es hat sich jedoch herausgestellt, daß mit den zuletzt genannten Maßnahmen beispielsweise Innenrisse nicht vermieden werden konnten.It has been found, however, that the measures mentioned last do not prevent internal cracks, for example could.

Der Erfindung liegt daher die Aufgabe zugrunde, die Mängel der bekannten Ausführungen zu beseitigen und durch entsprechende Anordnung und Ausbildung der Transportwalzen ein fehlerfreies Gußmaterial bei gleichzeitiger Verringerung der Bauhöhe von Vertikalgießanlagen bzw. der Baulänge von Bogengießanlagen herbei zuführen·The invention is therefore based on the object of the shortcomings to eliminate known designs and a faultless one by appropriate arrangement and design of the transport rollers Casting material with a simultaneous reduction in the overall height of vertical casting systems or the overall length of curved casting systems bring about

Dies wird dadurch erreicht, daß die Transportwalzen zum Fördern und Verformen des Stranges in der Anlage in an sich bekannter Veise in Höhe des noch flüssigen Strangkernes angeordnet sind und erfindungsgemäß der Durchmesser dieser Transportwalzen mindestens den 10-fachen Betrag der Dicke der erstarrten Strangschale in Höhe der anzuordnenden Rollen beträgt. Es wurde unter Berücksichtigung dieser Verhältnisse gefunden, daß ein Verfahren zum Fördern und Verformen von Strängen unter Verwendung von Transportwalzen der vorher angegebenen Art derart durchzuführen ist, daß der Strang bis zu 20 %, bezogen auf die Strangaußenfaser, verformt wird.This is achieved in that the transport rollers for conveying and deforming the strand in the system are arranged in a manner known per se at the level of the still liquid strand core and, according to the invention, the diameter of these transport rollers is at least 10 times the thickness of the solidified strand shell at the level of the roles to be arranged. Taking these circumstances into account, it has been found that a method for conveying and deforming strands using transport rollers of the type specified above can be carried out in such a way that the strand is deformed by up to 20%, based on the outer strand fiber.

In weiterer Ausbildung der Erfindung wird vorgeschlagen, gegebenenfalls - beispielsweise bei Brammensträngen - zwei Transportrollenpaare untereinander anzubringen und diese bei Quadratsträngen oder Rundsträngen unter Umständen um 90° gegeneinander versetzt anzuordnen. Die Transportwalzen können in an sich bekannter Weise als glatte Walzen oder auch als Walzen mit geschlossenem Kaliber ausgebildet sein.In a further embodiment of the invention it is proposed, if necessary - For example in the case of slab strands - to attach two pairs of transport rollers to each other and to use them at Square strands or round strands may be arranged offset by 90 ° from one another. The transport rollers can be in be designed in a known manner as smooth rollers or as rollers with a closed caliber.
