Abstract: The invention relates to a method for repairing slide plates of metallurgical containers. These types of slide plates consist of refractory material and have a passage opening for the discharge of the liquid metal, which is usually steel. Owing to corrosion and radial cracks, which orginate at the passage opening, these slide plates 5 become worn after a lengthy operating time. In order to be able to further use them to a large extent, the invention provides a bore, in the area of the opening, extending as far as the edge of the rim 6 of the slide plate, while the remaining refractory material is retained. Into this bore there is poured a refractory casting mass, the grain structure of which has a particular relation to the pore size of the retained refractory material. The essential fact is that the solid bodies of the refractory casting mass are predominantly smaller than the open pores, cut by means of the boring process, of the retained refractory material and can penetrate into the pores.
