摘　　要：以转炉车间六流方坯连铸中间包为研究对象，建立中间包钢液流动的水力学模型。通过水力学模型试验，优化中间包的内部结构，钢液平均停留时间从37s延长到了59s，将平均的死区比例从17．47％降低到了5．57％。A water model was built to study the flow field of the six-strand billet tundish in converter workshop. The experiment on simulating the flow of molten steel was carried out by the water model. The results showed that the internal structure of the tundish was optimized. The mean residence time was extended from 37s to 59s, and the average ratio of the dead zone volume was reduced to 5.57% from 17.47%.
