Numerical and Physical Parametric Analys

The continuous casting process for steel production has seen continuous improvements aimed at enhancing the quality and performance metrics within the industry. This work focuses on the specific role of submerged entry nozzles (SEN) augmented by flow conditioners. The objective is to evaluate how parameters such as thickness and length of fluid-flow modifiers can optimally influence the effectiveness of these nozzles in achieving a quasi-steady flow condition, crucial for the formation of a uniform solidified shell of steel. Utilizing both numerical and physical simulation methodologies, various configurations of these flow modifiers were tested to assess their impact on the mold flow patterns. Findings suggest that the design of fluid-flow modifiers should focus on maintaining minimal thickness while ensuring adequate length to achieve flow symmetry and reduce turbulence, which traditionally hinders the quality of the final product. This research contributes significant insights into optimizing the fluid dynamics in slab continuous casting processes, which is paramount for reducing defects and improving overall production efficiency.
