A continuous-casting-nozzle support apparatus capable of enhancing sealing performance between a continuous casting nozzle and an SN device. The continuous-casting-nozzle support apparatus comprises: a holding mechanismdisposed to extend from a stationary columnfixed onto a supporting surface, and adapted to be turnable in a horizontal direction and swingable or movable in an upward-downward direction; a lifting mechanismprovided on the side of a distal end of the holding mechanism; a supporting mechanismprovided on the side of a distal end of the lifting mechanism, and adapted to support a continuous casting nozzle; and a hooking deviceprovided in the lifting mechanism, and adapted to allow the lifting mechanismto be hooked to a first engagement portionformed on a sliding metal frame of a sliding nozzle device, wherein the lifting mechanismis adapted to lift the continuous casting nozzlethrough the supporting mechanism

Apparatus and method for supporting continuous casting nozzle, sliding nozzle system and continuous casting nozzle

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.
