  ABSTRACT: The numerical model of a slab mold with a section of 180 mm × 650 mm for three-dimensional flow field analysis was established based on the continuous casting process conditions in a factory. The effects of the immersion depth of the submerged entry nozzle, exit area, casting speed, and the inclination angle of the submerged entry nozzle on the flow field of the mold were analyzed. The results showed that when the immersion depth, exit area, casting speed, and inclination angle were 120 mm, 40 mm × 55 mm, 1.6 m/min, and 15˚, respectively, the slab mold can obtain an ideal flow field, and the free surface velocity and fluctuation can meet the production requirements, which providing a guidance for the optimization of the slab mold flow field. The industrial production test showed that the stronger interaction between the molten steel and the protective slag can be effectively weaken by increasing the inclination angle from 12˚ to 15˚, and the formation of central equiaxed grains can be promoted as well as the quality of continuous casting slabs.
