Abstract
A closing plate for a sliding closure on the spout of a receptacle for molten metal, especially of a converter, includes an elongate refractory plate and a sheet metal jacket surrounding the same. The refractory plate has a sliding surface which can be braced with a sliding surface of a refractory closure plate interacting therewith or with a sliding surface of a refractory head part. The refractory plate has at least one tapering section which forms an angle with the sliding surface on at least one side delimiting the sliding surface, each tapering section being associated with a section of the refractory plate that projects beyond the sheet metal jacket. The closing plate reduces the risk of damage to the front faces of the refractory parts 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.
