摘　　要：以计算流体力学理论为基础,利用Fluent软件建立了连铸结晶器内钢液流动的三维数学模型,运用模型低雷诺数方程对板坯结晶器内钢液的流场进行了模拟研究。通过数值计算研究了水口浸入深度、拉坯速度等工艺参数对结晶器内钢液流动状态的影响,为优化结晶器内的钢液流场分布、合理设计连铸结晶器装置和指导实际生产提供了依据。Based on the theory of calculation of fluid mechanics, the 3D-mathmatical model of fluid flow in the continuous casting mold was established by the Fluent-soft. The fluid flow in mould for slab continuous casting has been simulated using model of low Re equation. Through the numerical calculation, the effect of immersion depth of nozzle and casting speed were studied, which provided the basis for optimizing the flow field of molten steel in the mould, for designing reasonable slab continuous casting mold installation and for instructing actual production.
