Abstract
A tundish nozzle is used in a device for exchanging tundish nozzles juxtaposed at a bottom of a tundish. The device includes a pair of first arms pressing and supporting a first lower nozzle located at an undersurface of a first upper nozzle, the first upper nozzle being placed at the bottom of the tundish. The device includes a pair of second arms pressing and supporting a second lower nozzle located at an undersurface of a second upper nozzle, the second upper nozzle being placed at the bottom of the tundish and next to the first upper nozzle. The pair of first arms and the pair of second arms are adjoined to each other, the pairs at least partly overlapping. The tundish nozzle includes a zirconia based nozzle inserted into an alumina based refractory, and is one of the first and second lower and upper nozzles.
