以三流异型坯连铸中间包为研究对象,采用FLUENT软件对9种方案的中间包内钢水混合性能、温度场分布状况及夹杂物去除情况进行了数值仿真研究,结果表明:导流孔直径Φ=10 cm,导流孔高度L=55 cm,导流孔夹角α=50°时中间包综合性能最佳.%With three-strand H-beam blank continuous casting tundish as the research object and by using the FLUENT software , the mixing characteristics , the temperature distribution and the removal of inclusion in the tundish under nigh schemes were studied .The results showed that the tundish had the optimized comprehensive performance when the diameter of flow -guiding bore (Φ) is 10 cm,the height of flow-guiding bore (L) is 55 cm, and the angle between two flow-guiding bores (α) is 50°.
