Abstract
A slide unit for use in a sliding closure unit includes two partial movable refractory plates having respective planar surfaces. Each partial plate is surrounded circumferentially by a respective metal band. The two plates are assembled together in a frame to abut along a butt joint so that the two partial plates can be moved together with the planar surfaces thereof contacting a stationary refractory plate of a sliding closure unit. The metal bands at the area of the butt joint between the two partial plates is spanned by a refractory shoulder extending integrally from at least one of the partial plates. Such shoulder thereby extends the planar surfaces of the two plates to the butt joint so that the two planar surfaces form a continuous sealing surface.
