摘　　要： 以某钢铁公司的双辊薄带连铸机为原型,通过建立三维铸轧熔池流热耦合数学模型,研究了铸轧熔池近侧封板处的流场和温度场变化规律。结果表明,近侧封板处铸轧熔池存在三个较大的的漩涡区,与熔池内部流场有较大差异。研究还发现,端面布流水口倾角严重影响着熔池液面波动和上部钢液混合均匀程度,合理的水口倾角有利于熔池出口Kiss点高度的均匀一致,提高薄带产品质量。 According to the Twin-roll strip casting machine in a steel company, a three-dimensional mathematical model of fluid-thermal coupling is built for molten pool to study the flow and the temperature fields of molten pool near the side dam. The results show that three large vortex area appear in the molten pool near the side dam and it＇s different from the internal flow field. In addition, the inlet angle of the head face seriously affect the fluid level fluctuation and mixing degree of the upper steel liquid in molten pool. Using the reasonable inlet angle is beneficial to uniform the Kiss point height of molten pool, improve the quality of strip product.
