Abstract

Gießdüsen zum Zuführen von Stahlschmelze aus einem Zwischenbehälter in eine Stranggießkokille mit bewegten Kokillenwänden aus endlosen Gießbändern und endlosen Seitendämmen weisen ein Mundstück auf, welches unter Vermeidung von Luftzutritt und unter Bildung eines Dicht­ spalts zwischen die Kokillenwände hineinragt. Pouring nozzles for supplying molten steel from one Intermediate container in a continuous casting mold with moving Mold walls made of endless casting lines and endless Side dams have a mouthpiece, which is under Avoiding air entry and forming a seal gap protrudes between the mold walls.

Um das aus teurem Keramikwerkstoff gefertigte Mund­ stück (6) bei den vorliegenden engen Platzverhältnissen ausreichend dicht und schnell austauschbar mit dem in Gießrichtung (Pfeil 3) vorausgehenden Gießdüsenabschnitt (5) aus einem anderen, billigeren Keramikwerkstoff verbin­ den zu können, wird vorgeschlagen, die beiden genannten Teile (5, 6), die über einzelne Zentrierelemente (12) gegen Verschiebungen quer zur Gießrichtung gesichert sind, über aneinander anliegende stirnseitige feinbearbeitete Planflä­ chen (5′, 6″) gegeneinander abzudichten. Die die Abdichtung bewirkenden Dichtkraft wird über in das Mundstück (6) übergehende Zugelemente (20, 21, 22) erzeugt, die sich entgegen der Gießrichtung über das Mundstück hinaus erstrecken und deren Zugkraft über eine Spanneinrichtung (23) einstellbar ist. Around the mouth made of expensive ceramic material piece (6) given the limited space available sufficiently tight and quickly interchangeable with the in Pouring nozzle section (arrow 3) preceding section (5) made of a different, cheaper ceramic material To be able to do so, it is proposed, the two mentioned Parts (5, 6) against individual centering elements (12) Shifts across the casting direction are secured over adjacent, machined face surface chen (5 ′, 6 ″) to seal against each other. The sealing effective sealing force is in the mouthpiece (6) transitional tension elements (20, 21, 22) are generated against the pouring direction beyond the mouthpiece extend and their tensile force via a tensioning device (23) is adjustable.
