Abstract: An internal nozzle/plate assembly for a distributor, wherein the plate is placed against a support (13) with an aperture (30) therein. A central portion is arranged opposite the aperture (30) and a peripheral portion is placed against the support (13). The central and peripheral portions are linked via a weakened portion (32) so that the central portion may be separated from the peripheral portion by exerting a slight force. A metal shell (22) partially surrounds said central and peripheral portions and the weakened portion (32) may be formed from a scored or notched portion in the shell.

Abstract: A device for controlling a flow of liquid steel from a ladle (1) to a continuous casting distributor (8). The device includes a frame connected to the ladle (1) and comprising a guide assembly; a plate (3) movable on the guide assembly for sealing the casting opening (2); an assembly for compressing said plate (3); and a jet nozzle tube (4) extending from the casting opening (2). The plate for sealing the casting opening (2) is a sealing plate (3) designed only to seal the casting opening (2); the jet nozzle tube (4) and a plate (34) together form a rigid assembly moving along the guide assembly to a position opposite the casting opening where it replaces the sealing plate (3) which is thus driven from this position; and a compression assembly holds the plate (34) of the plate/jet nozzle tube assembly (4, 34) in sealing contact with a fixed upper plate (30).
