Abstract
A shut off plate assembly for use in a slide gate includes a refractory plate having on respective opposite sides thereof a planar surface defining a slide plane of the slide gate and a recess. A discharge opening extends through the refractory plate and at opposite ends thereof opens onto the planar surface and into the recess. The recess thus expands outwardly the discharge opening. An insert is formed of a highly refractory material and has therethrough a discharge opening. The insert is positioned in the recess with the discharge openings of the plate member and the insert in alignment and defining a discharge passage through the assembly. The insert and the plate member have respective confronting surfaces that define a joint that opens into the discharge passage. Thus, a gas may be injected through the joint into the discharge passage.
