<p>A closing plate for a sliding closure on the spout of a receptacle for molten metal, especially of a converter, comprises an elongate refractory plate (11) and a sheet metal jacket (12) surrounding the same. The refractory plate (11) has a sliding surface (14, 16) which can be braced with a sliding surface of a refractory closure plate interacting therewith or with a sliding surface (21′) of a refractory head part (21). The refractory plate (11) has a tapering section (26, 28, 29) which forms an angle (a) with the sliding surface (14, 15) on at least one side delimiting the sliding surface (14, 15), said tapering section being associated with a section of the refractory plate (11) that projects beyond the sheet metal jacket (12). The closing plate according to the invention allows the risk of damage to the front faces of the refractory parts to be braced with each other to be substantially reduced during bracing of the parts with each other and/or during a relative adjustment of the refractory parts that are braced with each other.</p> |
