<p>SLIDING GATE VALVES A sliding gate valve for controlling the flow of molten metal includes a refractory sliding plate 9 mounted in a movable frame 10, and co-operating with a fixed base plate 7. The sliding plate affords an opening which accommodates a wear insert 15,16 defining a flow opening in communication with a flow opening 19,20 defined by a replaceable refractory outlet sleeve 17,18 The outlet sleeve is removably connected by a mounting 21,22 to move with the sliding plate. The wear insert 15,16 is connected to the associated replaceable outlet 17,18 to constitute a wear part unit thereby permitting removal of the wear insert from the sliding plate without disassembly of the valve.</p> |
