Abstract

Es werden ein Verfahren und Anordnungen zum Anbinden eines neuen Gießstranges an einen vorhergehenden Strang beim kontinuierlichen Stranggießen in einer Stranggießanlage beschrieben. There will be a procedure and arrangements for tying a new one Cast strand to a previous strand in the continuous Continuous casting described in a continuous caster.

Die Stranggießanlage verfügt über einen Zwischenbehälter mit einer verschließbaren Ausflußöffnung. Unterhalb der Ausflußöffnung ist eine gekühlte Stranggießkokille angeordnet, in der das Anbinden des neuen Gießstranges stattfindet. Das Verfahren zum Verbinden zweier Gießstränge in einer Stranggießkokille beim Chargenwechsel macht ein kurzzeitiges Verschließen des Kokillenausgangs nötig, was durch Öffnen des Kokillenausgangs, Gießen eines Stranges, Anbringen von Anbindemitteln an das Strangende und Verbindung des vorherigen Endes des neuen Stranges mit den Anbindemitteln zur gemeinsamen weiteren Verarbeitung beider Stränge erreicht wird. Die Anordnungenen zum Anbinden entweder eines Kaltstranges oder eines vorlaufenden, noch warmen Gießstranges verwenden als Anbindemittel einen rohrstutzenartigen Körper, der im einfachsten Fall aus einem, dem Kokillenquerschnitt im Querschnitt geometrisch ähnlichen Rohrstüc besteht. In diesem rohrförmigen Körper bildet sich durch Aufschrumpfen der Strangschale beim Erkalten eine kraftschlüssige Verbindung. The continuous caster has an intermediate container with a closable outflow opening. A cooled continuous casting mold is arranged below the outflow opening, in which the new casting strand is connected. The process of connecting two casting strands in a continuous casting mold when changing batches necessitates a short-term closure of the mold outlet, which is achieved by opening the mold outlet, casting a strand, attaching binding agents to the end of the strand and connecting the previous end of the new strand to the binding agents for further processing together of both strands is reached. The arrangements for connecting either a cold strand or a leading, still warm casting strand use a pipe socket-like body as the connecting means, which in the simplest case consists of a pipe section that is geometrically similar to the mold cross section in cross section. In this tubular body, a shrink-fit connection is formed when the strand shell is shrunk on cooling.
