Abstract Based on the basic theory of fluid mechanics, according to the structure and parameters of the mould for slab continuous casting, the k-ε turbulence model of the commercial software fluent was used to realize the three-dimensional mathematical simulation of molten steel in mold. The effects of technological parameters such as nozzles shape, submerged depth of nozzles, side-hole angle and the casting speed, on the mold steel flow field are emphatically investigated. Results showed that for 2300mm×250mm slab mold, flow field was better when the submerged depth of nozzles was 150mm, side-hole angle was under 15° and the casting speed was 1.2m/min.The numerical results provide a theoretical basis for the wide-slab continuous casting mole to determine a reasonable process parameters.
