Analysis of the fluid flow behavior within a beam blank mold using submerged-entry nozzle with three exit ports.

Abstract

Through the use of physical and mathematical modeling techniques, liquid flow inside a beam blank mold with a submerged valve consisting of three exit ports has been analyzed. The behavior of the slag metal interface was evaluated using water and an aqueous NaCl solution to simulate steel. Slag simulation was done using silicon oil. Increased casting speed results in increased free surface oscillation. For the fluid density of 1,000 kg/m3, oil entrainment started at a casting velocity of 0.98 m/minute. For a fluid density of 1,170 kg/m3, no entrainment was observed in any of the conditions studied.
