Numerical Modeling of Steel Flow in the Six-strand Tundish with Different Flow Control Devices

Modern steel making processes are based on electrical arc furnaces (EAF) or converters, secondary metallurgy and CSC equipment. Steel casting processes are carried on as the continuous ones, which today are the dominating methods in global quantities of steel production. These methods make possible production of the continuous castings of predetermined profiles and dimensions, and therefore to reduce significantly the product manufacturing costs. The component of equipment, which significantly influences the course of the continuous steel casting process, is called the tundish. A stabilized flow of steel in the tundish greatly affects the process characteristics related to quality, performance and economical issues. Today the main direction of research works concerning the tundishs refers to the refinement processes of the non-metallic inclusions, to lessening the transient zone in the continuous castings and to equalizing the temperatures of the steel being cast. In the work presented here we show the results of numerical simulations 1 illustrating steel motion in the tundish equipped with different flow control devices arrangements.
