Refractory plate assembly for use in sliding closure unit

摘要

A refractory plate assembly for use as a stationary or a movable refractory plate in a sliding closure unit includes a refractory supporting body and a refractory disc-shaped member forming a sliding sealing surface of the assembly. The disc-shaped member is loosely and removably mounted to the supporting body in a manner to prevent the disc-shaped member from working loose from and moving relative to the supporting body.
