Abstract

A sealing for interlocking refractory components (1 and 2) containing a metallic melt is improved by the fact that at least one radially acting ceramic spring washer (4) for sealing the cross-section of the clearance fit (3) between the components (1 and 2) is arranged at least on one component in an annular groove (5). <IMAGE> <IMAGE> <IMAGE
