Die Erfindung betrifft ein Tauchgießrohr zum Einleiten von Stahlschmelze in den Eingießbereich einer aus Breitseitenwänden und Schmalseitenwänden bestehenden Kokille insbesondere zum Gießen dünner Stahlbänder, bestehend aus einem an einem Gießbehälter angeschlossenen Rohrteil und einem Endteil, das in Richtung der Schmalseitenwände mit je einer Ausströmöffnung und einem stirnseitigen Bodenstück versehen ist.The invention relates to a submersible pouring tube for introducing molten steel in the Eingießbereich consisting of broad side walls and narrow side walls mold especially for casting thin steel strips, consisting of a connected to a casting container tube part and an end portion in the direction of the narrow side walls, each with an outflow opening and a front-side bottom piece is provided.
schlitzartigen Austrittsöffnungen und ein Bodenstück mit erhabener Innenkontur angeordnet. Das Bodenstück hat in Richtung der Ausströmöffnungen eine größere Ausdehnung als der Abstand der die Ausströmöffnungen nach oben begrenzenden Wandungen.slit-like outlet openings and a bottom piece arranged with a raised inner contour. The bottom piece has a greater extent in the direction of the outflow openings than the spacing of the walls which delimit the outflow openings upwards.
erforderlichen Betriebssicherheit und Standzeit gewachsen.required operational safety and durability have grown.
insbesondere in einer schmalen Stahlbandgießkokille zu Auswaschungen an der noch dünnen Strangschale und zur Ausbildung einer Stauwelle vor den Schmalseitenwänden kommt. Darüber hinaus kommt es bei Verwendung des bekannten Gießrohres aufgrund ungleicher Strömungsverteilung innerhalb der Kokille zur Ausbildung einer unregelmäßigen Oberflächenstruktur.especially in a narrow Stahlbandgießkokille to washouts on the still thin strand shell and to form a surge wave in front of the narrow side walls. In addition, when using the known pouring tube due to uneven flow distribution within the mold to form an irregular surface structure.
den flüssigen Stahl stark vermindert und ein Gießstrang, insbesondere Stahlband, mit gutem Gefüge und gleichmäßig fehlerfreier Oberfläche erzielt wird. Darüber hinaus soll beim Angießvorgang des Hochspritzen und Anbacken von Stahlschmelze an den Kokillenwänden vermieden werden.greatly reduces the liquid steel and a casting strand, in particular steel strip, is achieved with good texture and uniformly flawless surface. In addition, should be avoided at the casting process of high spraying and baking of molten steel to the mold walls.
ungleiche Austrittsgeschwindigkeit über die Austrittsquerschnitte ist.Unequal exit velocity over the outlet cross sections.
Ziel der Erfindung iet es, die durch ungleiche Austrittegeschwindigkeiten verursachten Instabilen Schmelzenverteilungen und die daraus resultierenden Qualitätsnachteile auszuschalten. Darüber hinaus soll beim Angießvorgang das Hochspritzen und Anbacken von Stahl an den Kokillenwänden vermieden werden.The aim of the invention is to eliminate the unstable melt distributions caused by unequal exit velocities and the resulting quality disadvantages. In addition, the high spraying and baking of steel to the mold walls should be avoided during the casting process.
in Richtung der Ausströmöffnungen eine geringere Breite a hat als der Abstand b der die Ausströmöffnungen nach oben begrenzenden Wandungen.in the direction of the outflow openings has a smaller width a than the distance b of the outflow openings upwardly bounding walls.
