Effect of Shape and Flow Control Devices on the Fluid Flow Characteristics in Three Different Industrial Six Strand Billet Caster Tundish

摘要

Fluid flow phenomenon in a tundish depends upon the shape of tundish. The change in the shapes can bring drastic change in the flow pattern and thus effect the fluid flow characteristics in the tundish. The signifiacnt effect of flow control devices on fluid flow phenomenon is also noticed. In the present work, investigation of fluid flow phenomenon was performed for the symmetrical half of a six strand tundish. Fluid flow pattern gets altered by changing the shapes of tundish and pouring chamber. The impact of this change results in a development of various flow patterns. These flow patterns are analysed for capturing the better inclusion flotation. The mathematical model has been validated by the experimental results of Singh and Koria for a single strand bare tundish.
