Abstract

Language:

In steel continuous casting systems, nozzles play a crucial role in flow rate control of molten steel and elimination of inclusions. This study aimed to determine an optimal nozzle bore profile for both tundish upper nozzle (TD) and submerged entry nozzle (SEN) to suppress turbulence with high kinetic energy in molten steel flow. A combination of computational fluid dynamics (CFD) simulations and water model experiments was employed to minimize the turbulence. Results indicated that the newly devised inner bore profiles effectively reduced turbulence and the adhesion of alumina inclusions to the nozzles by minimizing energy loss. The practical implementation of the manufactured nozzle in steel works led to satisfactory outcomes, enhancing both operational stability and steel quality. This development holds significant implications for improving continuous casting efficiency and product quality in steel manufacturing.
