Avoiding Asymmetric Flows Caused by Off-Center Pouring Into the Tundish: A Novel Impact Pot Design

Off-center and angled pouring of molten steel into the tundish by a misaligned ladle shroud might result in several problems caused by the asymmetric flow, such as: short-circuiting flows, inhomogeneous temperature distribution and higher tendency of vortex formation with consequent slag entrainment, among other issues. Although many different impact pot designs are available in the industry, none have effectively addressed the issue of asymmetric flows caused by off-center pouring. This paper presents the development of a novel impact pot design which can perform well even under such adverse conditions, as shown by mathematical and physical modeling studies.
