A slide gate valve (10) having a replaceable refractory valve plate assembly is provided for facilitating maintenance operations. The slide gate valve generally comprises a metallic frame (12) mounted on a metallurgical vessel (1), at least one fixed refractory plate having one flow opening, at least one moveable refractory plate (16) having a flow opening, a pouring nozzle firmly connected to the moveable plate, a pneumatic cylinder for controlling the displacement of the moveable plate with respect to the fixed plate (14) in order to control the overlap of the flow openings of the two plates, and an interconnection structure for unitizing the fixed and moveable refractory plates (16) and the pouring nozzle into a valve plate assembly that is installable in and removable from the metallic frame of the slide gate valve in a single operation. The refractory plates may each be covered by metallic shells and the interconnecting structure may take the form of slidably interfitting rails and recesses between the two metallic shells which unitize the refractory plates during a replacement operation, but which allow the pneumatic cylinder to displace the fixed and moveable plates during the operation of the slide gate valves.
