Numerical evaluation of a submerged entr

In continuous casting machines of steel, clogging of the submerged entry nozzle (SEN) significantly impacts product quality. This document addresses the issue by proposing a modification to the SEN that promotes uniform flow at its exit. The objective is to extend the SEN's operational lifespan through an active self-cleaning mechanism. Notably, this modification involves replacing the static bottom section of the SEN with a conical sliding device. To analyze the device's performance, computational fluid dynamics (CFD) simulations were employed, focusing on its behavior under non-steady state conditions. Results indicate that the hydrodynamic flows within the nozzle and the vertical movement of the conical device effectively regulate the release of inclusions into the mold, thereby improving the overall quality of the steel produced. This investigation underscores the importance of design parameters of the SEN and their direct influence on the casting process, contributing to enhanced industrial applications and efficiency in steel production.
