A movable refractory plate assembly for use in a sliding closure unit for controlling the discharge of molten metal from a metallurgical vessel includes a movable refractory plate having therein at least one aperture and having a sliding surface. A replaceable refractory erosion unit, which may be integral or which may include a separate erosion insert and a separate discharge nozzle, is positioned within the aperture of the movable refractor plate. The erosion unit has therethrough a discharge opening and has a sliding surface aligned with a sliding surface of the movable refractory plate. A frame supports the movable refractory plate for movement, and a support coupling removably mounts the erosion unit with respect to the movable refractory plate.
