Abstract

1. A method for repairing lower and upper slide plates (5) of closures in metallurgical containers, in particular in casting ladles and tundishes for continuous casting, the slide plates optionally releasing the stream of liquid metal by means of a passage opening (1) or interrupting it by means of a closed section, and undergoing damage, in particular erosion and radial cracks, originating at its passage opening (1) in which method a bore is made in the area of the opening of the slide plate concentrically with respect to its passage opening (1) and while the passage opening (1) is released, a refractory casting mass (13) is poured into the bore and is solidifed therein, characterized in that the bore, which is concentric with respect to the passage opening (1) is made as far as the edge of the rim (6) of the slide plate (5), and in that the grain sizes of the solid bodies of the refractory casting mass (13) are predominantly smaller than the pore sizes of the retained refractory material (10) of the slide plate (5).
