摘要： An adjustable impact casing for use in a shaft furnace is formed of a plurality of upwardly extending segments. The segments are arranged in an inner circular row enclosed by an outer circular row. In each row, segments are spaced angularly apart and are offset to the segments in the other row with their upwardly extending lateral edges arranged in overlapping and substantially contacting relationship. The segments are pivotally supported about axes extending transversely of the upright axis of the casing and as segments in the inner row are secured to one adjustment drive arrangement while the segments in the outer row are secured to another adjustment drive arrangement. A control circuit is connected to the adjustment drive arrangements for regulating the movement of the segments between spaced positions. Initially, the segments in one of the rows are spaced from the segments in the other row. Then, the two rows are moved together toward a new position with one row of segments moved into the new position. Finally, the other row of segments is displaced into contact with the row of segments already in position.
