ABSTRACT:
A slide plate assembly includes a refractory slide plate having a through-flow opening therethrough and embraced within and supported by a slide plate operating frame. The frame includes a main frame member having a side and opposite ends and a side member. The side member is removably attached to the opposite ends of the main frame member in a manner such that it is movable toward and away from an adjacent portion of the periphery of the slide plate. The inner surfaces of the side of the main frame member and the side member are non-parallel and divergent such that the slide plate is grasped from three areas by forces which converge generally toward the through-flow opening through the slide plate.
