摘要： An apparatus for changing casting nozzles such as immersion nozzles easily, quickly, and reliably. The apparatus has a holder frame fixed to the bottom of a molten metal pouring device and defining a substantially C-shaped casting nozzle travel passageway composed of a new-nozzle insertion passage, an old-nozzle ejection passage extending parallel thereto in spaced-apart relationship, and a joint passage connecting the new-nozzle insertion passage and the old-nozzle ejection passage to each other, and having a casting position where the casting nozzle is held under compression; a spring box mounted in the holder frame and having outer side portions resiliently supported by springs on opposite sides of the holder frame across the casting nozzle travel passageway, the spring box having on inner sides thereof guide rails forming part of side portions of the casting nozzle travel passageway, a nozzle moving mechanism mounted on the holder frame for moving the casting nozzle along the guide rails; and a lifting mechanism for lifting the casting nozzle in unison with the spring box in response to movement of the casting nozzle along the guide rails until the casting nozzle is fittingly held against the bottom of the molten metal pouring device.

摘要： A sliding nozzle plate-metal frame fixing structure which allows the sliding nozzle plate to be mounted to and removed from the metal frame with ease. The sliding nozzle plate which is used with a sliding nozzle device attached to a molten metal vessel has a sliding surface, and is surrounded by a metal case with the exception of the sliding surface. The metal case has a projection or a plurality of projections of a particular shape on the surface of the plate opposite the sliding surface, and a metal frame in which the metal-cased plate to be mounted has a plurality of concave portions corresponding to the projection or projections of the metal case, so that the metal-cased plate can be mounted to and removed from the metal frame simply and accurately through engagement and disengagement of each of the metal case projection or projections with each of the metal frame concave portions.
