Long nozzle for continuous casting |
摘要 |
The present invention relates to a long nozzle used to prevent molten steel flowing out of a collector nozzle of a sliding nozzle from being oxidized by atmospheric air when molten metal, particularly molten steel is poured from a ladle into a tundish. This nozzle has a construction comprising: (a) the long nozzle (3) made of a refractory causes molten metal to flow down from the collector nozzle (2) and the head thereof is covered by a metallic shell (16); (b) a first gas passage is provided to blow inert gas to the vicinity of a fitting portion (7) between the collector nozzle (2) and the long nozzle (3) through a first gas inlet port (8) provided on the side wall of the metallic shell (16); and (c) a second gas passage is provided to blow inert gas into an inner hole (18) of the long nozzle through a second gas inlet port (10) provided on the side wall of the metallic shell (16).
