Abstract

Fluid flow of liquid steel in a slab mold influenced by three different submerged entry nozzles with the same bore sizes but different ports including rectangular, square, and round shape at immersion depth of 185 mm was studied. The analysis includes numerical simulations and physical modeling. The results show that the port shape has great effects over the fluid dynamics of the liquid steel inside the slab mold. The comparison among the three nozzle port designs indicates that the nozzle with square ports, (SEN-S), decrease the jets velocity, promote a symmetrical path inside the mold and decrease the bath level oscillations; representing the best choice to control the turbulence and decrease the quality problems.
