Abstract
An assembly of refractory plates for a three-plate sliding closure unit includes an inlet stationary refractory plate having therethrough an outlet opening, an outlet stationary refractory plate having therethrough an outlet opening, and a movable refractory plate mounted between the inlet and outlet stationary plates and having an outlet opening. The movable plate is slidable relative to the stationary plates between closed, open and throttled positions. The axis of the outlet opening in the outlet stationary plate is offset in a closing direction of movement of the movable plate from the axis of the outlet opening in the inlet stationary plate. The inlet end of the outlet opening in the outlet stationary plate is widened.
