根据Fr和Re准数相似的原则,建立了双辊薄带连铸机的1∶1水模型,并设计了新型的布流系统.采用数学模拟的方法研究了熔池内流体的流动状态,分析了布流系统结构对熔池内流场的影响.利用三维激光多普勒测速仪测量了侧封板处的流场分布.模拟结果与测量结果比较吻合.
According to the similarity principle of Fr and Re’s quasi-number, a 1: 1 water model of a twin-roll strip caster was established and a new type of distribution system was designed.The mathematical model was used to study the flow state of the fluid in the molten pool, The influence of the distribution system structure on the flow field in the weld pool was investigated.The distribution of flow field at the side seal plate was measured by a three-dimensional laser Doppler velocimeter.The simulation results were in good agreement with the measured results.
