Hydraulic Simulation of Fluid Flow in Beam Blank Continuous Casting Mold with Double Nozzles

"Processing parameters of a submerged entry nozzle (SEN) affect significantly on the patterns of fluid flow and temperature distribution in beam blank continuous casting mold with double SEN s. Effect of the geometry structure and immersion depth of double SEN s on the fluid flow in beam blank continuous casting mold was studied by water modeling. Results showed that, the optimal nozzle inner diameter was 40mm, and immersion depth was 70-90mm. The mold surface fluctuation, slag distribution, impact depth and removing rate of inclusion particles were discussed under different processing parameters of double SENs. As the results indicated, slag distribution was more non-homogeneous with a higher casting speed. The results provided basic data for the design and optimization of SENs used in beam blank continuous casting mold.IntroductionNear-net-shape casting has the distinct advantages of less rolling procedures, higher metal recovery and lower energy cost. Therefore, in the recent decades, one of the recent trends in the steel making process is moving toward near net shape casting. in which beam blank casting is a typical technology. The schematic section of beam blank is shown in Fig 1."
