摘要
根据有效雷诺数Ｒｅｅｆｆ相似准则，做了铝铸轧铸嘴型腔熔体流动的水模拟实验，实验结果显示铸嘴型腔熔体流动行为受分流块相对位置、分流块结构尺寸、分流块数目影响很大，认为：使用小尺寸分流块，或适当增加分流块数目以及对于渐扩式侧壁的铸嘴型腔，转动分流块使其平行于侧壁，都能够获得更均匀的出口分布速度。
A water modeling test of melt flow was worked with regard to nozzle cavity for aluminium roll casting according to Reeff similarity criteria. The results of experiments showed that the flow behaviour of melt in the nozzle cavity was affected to varying degrees by the relative position of spacer. The following conclusion were elicited by experiments: A more uniform exit distribution velocity would be obtained by using small scale spacer, adding to suitable amount of spacer, turning spacer to parallel wall for divergent side riser of nozzle cavity.
