Abstract (en)

[origin: EP0296443A2] Method and device for automatically filling a continuous casting mould with molten metal (steel), in which the molten metal (13) is poured into the continuous casting mould (18) in a controlled fashion through a bottom pouring nozzle (14) of a distributing launder (10) or of a tundish, the said nozzle being closable by means of an automatically actuated plug (15). During the filling of the continuous casting mould (18), the plug (15) executes predetermined upward and downward movements (double arrow 45) dependent, in particular, on the liquid level (19) in the continuous casting mould (18), the said movements being effected counter to the action of a force which urges the plug (15) into the closed position. The upward and downward movement of the plug (15) is effected by an actuating member (B) engaging directly on the upper end of the said plug. The force urging the plug (15) into the closed position is obtained either by means of a constant mass (121) or a resilient element (48) which, as the temperature rises, attempts to urge the plug (15) in a correspondingly increasing fashion into the closed position. Closed gas-filled springs (48) are preferably used as the resilient element, while the actuating member (B) is preferably formed by open spring elements (49) which correspond in their design to the closed spring elements (48). <IMAGE>
