Determination of an Optimized Submerged Entry Funnel (SEF) Configuration for Beam Blank Mould

A three-dimensional mathematical model is validated and established for studying the fluid flow inside a beam blank mould. Comparison of the model result with results available in public domain is done to validate the numerical analysis technique. Flow characteristics of a 430 mm × 350 mm × 90 mm beam blank mould have been studied with five different SEF configurations, namely (a) straight bore, (b) 2 ports–no central bore, (c) 2 ports–1 central bore, (d) 3 ports–no central bore and (e) 3 ports–1 central bore. The mould flow analysis with different SEFs reflects that with straight bore SEF, problem of inactive meniscus is dominant. Both types of 2-port SEF’s flange region experiences a high impact velocity from incoming steel jet. The 3-port SEF without central bore leads to high velocities on both the flange and web region. The 3-port SEF with central bore is found to satisfy all the mould flow criteria and suggests a stable mould fluid flow.
