In steel continuous casting system, nozzles have an important role on the flow rate control of the molten steel and the elimination of the inclusions etc. Based on the fundamental principle of hydrodynamics, the optimal nozzle bore profile was determined for both tundish (TD) upper nozzle and submerged entry nozzle (SEN) with aiming to suppress the turbulence with high kinetic energy generated in the flow of the molten steel. A simulation by flow analysis using computational fluid dynamics (CFD) and a water model experiment were performed and clarified that the turbulence with high kinetic energy could be minimized in the nozzles with newly devised inner bore profile. The actual nozzle devised was manufactured and tested in the steel works with satisfying results. The adhesion of the alumina inclusions to the both nozzles is reduced by lowering the turbulent kinetic energy since the energy loss is minimized at the part. Both stability in the operation and quality of the steels have been brought by the present development.
