Abstract Scope To improve the quality of steel slabs, the effects of the submerged entry nozzle (SEN) on fluid flow in a slab mold (1500mm× 200 mm) were investigated by using a 1:2 scale water model and a three-dimensional mathematical model. Through the analysis of mold level fluctuations, flux covering, flow field and so on under different nozzle structures and operating parameters of the existing and optimized nozzles, the optimum operating conditions of the existing and optimized nozzles were obtained, and then the reasonable submerged entry nozzles were put forward in this slab mold. The physical and mathematical simulations provide a scientific basis for optimizing flow field and SEN structures design in steel slab molds as well as for determining the best operating parameters for the existing process.
