Abstract (en)

A continuous casting process, comprises locating the melt feed opening (90) for the mould (24) in the tundish (40) and altering the metal level (M) in the tundish (40) to adjust the metal level above the opening (90). A continuous casting process comprises feeding molten metal (29) from a runner (42) into a tundish (40) and from the tundish through a passage opening (90) to form a free meniscus (29) in the inlet opening (26) of a mould (24) which forms a closed cross-section with inlet and outlet openings (26, 30). The melt supply to the mould (24) is regulated by adjustment of the metal level (M) in the tundish (40) and adjustment of the metal level above the passage opening (90). The passage opening (90) is located in the tundish (40) and the metal level (M) in the tundish (40) is altered to adjust the metal level above the passage opening (90). An Independent claim is also included for a continuous casting machine for carrying out the above process.

Abstract (de)

Eine Giessmaschine zum kontinuierlichen Giessen von Metall (28) zu einem Strang (32) weist eine Giessform (24) mit einem geschlossenen Querschnitt mit einer Eintritts (26)- und einer Austrittsöffnung (30) mit stetig mitwandernden, gekühlten Formwandungen auf. Flüssiges Metall (28) wird über eine Giessrinne (42) einem Giessbecher (40) zugeführt und aus dem Giessbecher sowie durch eine Durchtrittsöffnung (90) hindurch unter Ausbildung eines sich in Abhängigkeit vom metallostatischen Druck in der Giessform (24) einstellenden freien Meniskus (29) in die Eintrittsöffnung (26) der Giessform (24) gegossen und der in der Giessform erstarrende Strang (32) tritt aus der Austrittsöffnung (30) aus. Die Giessmaschine weist eine erste Regelanordnung (58) zur Einstellung des Metallstandes (M) im Giessbecher (40) und eine zweite Regelanordnung (92) zur Einstellung des Metallstandes über der Durchtrittsöffnung (90) zur Regelung der Zufuhr von flüssigem Metall (28) zur Giessform (24) auf. Die Durchtrittsöffnung (90) ist im Giessbecher (40) angeordnet und mit der zweiten Regelanordnung (92) zur Einstellung des Metallstandes über der Durchtrittsöffnung (90) ist der Metallstand (M) durch Kippen des Giessbechers um eine Kippachse (t) veränderbar. <IMAGE>
