摘要
基于流体力学的基本理论,利用商业软件fluent的κ-ε湍流模型,实现了对结晶器内钢液流场的三维数学模拟.重点分析了浸入式水口的形状、插入深度、水口侧孔倾角以及拉速等工艺参数对结晶器钢液流场的影响.结果表明,对于断面为1 280 mm×180 mm的板坯结晶器,水口插入深度为150 mm,水口倾角为向下15°,拉坯速度为1 m/m in时,结晶器内的流场较好.
Based on the basic theory of fluid mechanics,the κ-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 were emphatically investigated.Results showed that for 1 280 mm×180 mm slab mold,flow field was better when the submerged depth of nozzles was 150 mm,side-hole angle was under 15°,and the casting speed was 1 m/min.
