ABSTRACT:
A refractory plate-frame assembly for use in a sliding closure unit includes a frame having therein a recess and a refractory plate positioned within the recess. A flexible band is mounted within the recess about the periphery of the refractory plate. A tightening device is mounted in the frame and is selectively operable from the exterior thereof to tighten the band about the periphery of the plate and thereby securely mount the plate within the recess, and alternatively for loosening the band from the periphery of the plate, whereby the plate may be removed from the band and the frame.
