Das Brammenprofil ist im Wesentlichen von der Rollenspaltgeometrie im Bereich der Resterstarrung des Stranges abhängig. Durch Ausrichtfehler, Rollenverschleiß, elastische Verformungen des Segmentes, infolge Temperatureinfluss und unterschiedliche Gießbreiten, sowie durch ein unterschiedliches Erstarrungsprofil über die Gießlänge und -breite entsteht eine Rollenspaltgeometrie und damit ein Gießprofil, welches den hohen Anforderungen des Walzwerks und damit des Endprodukts teilweise nicht genügt. The slab profile is essentially in the range of the roll gap geometry the Resterstarrung the strand dependent. Due to alignment error, roller wear, elastic deformations of the segment, due to temperature influence and different casting widths, as well as a different solidification profile over the casting length and width creates a roller gap geometry and thus a Casting profile, which meets the high demands of the rolling mill and thus of the final product partly not enough.

Eine zur Durchführung des Verfahrens geeignete Stranggießanlage zur Erzeugung von Brammen enthält vier positions- und kraftgeregelte Segmentanstellzylinder, die die beiden Segmentrahmenteile mit Abstand - ohne Distanzstücke - miteinander verbinden und gegeneinander verspannen.A continuous casting plant suitable for carrying out the process for producing slabs contains four position- and force-controlled segment setting cylinders, the two segmental frame parts with distance - without spacers - with each other connect and clamp against each other.
Das Dokument DE 43 06 853 A1 beschreibt eine Strangführung an Stranggießanlagen für die Erzeugung von Brammen, insbesondere nach dem Gießwalzverfahren, mit auf unterschiedliche Strangdicken einstellbaren, paarweise gegenüberliegenden Rollen, die an durch Zuganker verbundenen Rahmen oder Gerüstteilen der Strangführung gelagert und deren Zuganker von Kolben-Zylinder-Einheiten gebildet sind und im Kraftfluss der Kolben-Zylinder-Einheiten zwischen oberen und unteren Rahmenteilen Distanzstücke eingelegt sind. Zwischen Distanzstück und Zylinder der Kolben-Zylinder-Einheit ist ein Hydraulik-Ring-Zylinder angeordnet, der die Kolbenstange umgibt und dessen Ringkolben kraftschlüssig das Distanzstück trägt. Die Hydraulik-Ring-Zylinder sind auf Seitenrahmen abgestützt und die Seitenrahmen verbinden mindestens zwei Unterrahmen zu einem Segment der Strangführung.The document DE 43 06 853 A1 describes a strand guide on continuous casting for the production of slabs, in particular after the casting-rolling process, with adjustable to different strand thicknesses, in pairs opposite Rollers attached to tie rods connected to frame or scaffolding parts stored the strand guide and its tie rods of piston-cylinder units are formed and in the power flow of the piston-cylinder units between upper and Lower frame parts spacers are inserted.
