ABSTRACT:
A slide valve for the outlet of a metallurgical vessel includes a stationary plate having a flow-through opening and adapted to be fixedly positioned beneath an outlet in a metallurgical vessel, and a slide plate mounted beneath the stationary plate for sliding movement with respect thereto between plural positions, the slide plate having plural flow-through openings adapted to align with the flow-through opening of the stationary plate at respective of the plural positions of the slide plate. A nozzle support member is mounted beneath the slide plate and is movable therewith. A plurality of nozzle members having therethrough nozzle openings are selectively removably mounted on the nozzle support member for movement therewith at positions with each nozzle opening being aligned with a respective flow-through opening of the slide plate. The nozzle opening of at least a first nozzle member is free and unobstructed, thereby forming an outlet nozzle for the discharge of liquid melt. The nozzle opening of at least a second nozzle member has therein an injector device, thereby forming an injector nozzle for the injection of material therethrough and into the respective flow-through opening of the slide plate.
