| 摘 要： | 根据长8 m,钢水液位0.8 m的3流H型连铸坯中间包,采用FLUENT软件建立三维几何模型模拟研究了弧形挡墙导流孔直径D（100~200 mm）,导流孔高度H（350~550 mm）和两导流孔夹角θ（20°~50°）对中间包内钢液的流场和温度场分布、钢液的混合状况及不同粒径夹杂物上浮去除的影响,结果表明导流孔直径D 100 mm、导流孔高度H 550 mm、导流孔夹角θ 50°时,中问包综合传递性能最优,各流平均停留时间差和各出口钢水温度差较小,大颗粒夹杂去除率达76%。

| Abstract: | Based on tundish with length 8 m and liquid level 0.8 m for 3-strands H-beam bloom casting, the effect of curved dam flow-guiding hole diameter D(100~200 mm) and hole height H(350~550 mm) and angle between two flowguiding hole θ(20°~50°) on distribution of tundish liquid flow field and temperature field, liquid mixing status and removal of inclusions with different size has been simulated and studied by using three dimensional geometry model established with FLUENT soft ware. Results show that with flow-guiding hole diameter D 100 mm and height H 550 mm, and angle between two flow-guiding hole 0 50°, the comprehensive transfer performance in tundish is best, i. e. the difference of average residual time at each strand and the difference of temperature of liquid at each outlet are smaller and the removal rate of large size inclusions is up to 76%. |
