Abstract: To improve the quality of steel slabs, the effects of submerged entry nozzle Structures on fluid flow in a slab mold (1500mm×200mm) 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 nozzle structure were put forward in this slab mold. The physical and mathematical simulations provide a scientific basis for optimizing flow field and nozzle structures design in a steel slab mold as well as for determining the best operating parameters for the existing process.
