Abstract
A fixing device for a ceramic sealing plate in a carrying frame or cassette of a seal on a metallurgical vessel has the sealing plate held by a band on the carrying frame or the cassette. To press the sealing plate evenly along its perimeter, the band is corrugated in its longitudinal direction. One set of ridges of the band lies elastically on the sealing plate. The ridges lying between the one set lie elastically on the carrying frame or on the cassette, or on a spacer sheet between the band and the carrying frame of the cassette.
