MIXING CHAMBER

摘要

The invention relates to a mixing chamber (10) for use in a metal transfer vessel (for example, a tundish used in steel manufacture or a holding furnace used in aluminium manufacture). The mixing chamber comprises a base with a first series of wall components (14,16,18,20) defining a first mixing zone (22) and a second series of wall components (28, 30). A second mixing zone (56,58) is defined between at least one of the second series of wall components (28,30) and at least one of the first series of wall components (14,16,18,20). A continuous flow path is provided from the exterior of the mixing chamber to the first mixing zone, from the first mixing zone to the second mixing zone, and from the second mixing zone to the exterior of the mixing chamber. The region of the flow path between the first mixing zone and the second mixing zone being defined by a first cut-out (42) in at least one of the first wall components (28,30) and the region of the flow path between the second mixing zone (56,58) and the exterior of the mixing chamber being defined by a second cut-out (64,66) in at least one of the second wall components. The first cut-out (42) is spaced from the base and the first and second cut-outs are mutually spaced along the flow path within the second mixing zone such that in use the general directions of flow within the second mixing zone and between the first and second mixing zones are different.
