Abstract
The size distribution of Al2O3 inclusion in Al killed liquid steel in the tundish is studied with a mixing model of constant flow stirred tank reactor and piston flow reactor.The flow fields and inclusion removal ratios of bare tundish and the tundish with dams and weirs are compared and the inclusion removal ratio of bare tundish is only 19%.However by installation of dams and weirs in the tundish the inclusion removal ratio reaches 37 %,which is greatly superior over that of the bare one owing to continuously growth of the grain sizes of the inclusions arising from turbulent flow and piston flow caused collision of the inclusions with each other.
