摘　　要：为使天钢六流方坯连铸中间包内钢液流动特性更加合理,采用水力学物理模拟实验,研究了导流孔距底部距离为110、80、60、30 mm时钢液流的动特性。结果表明,随着导流口距底部距离的降低,中包死区比例降低,滞止时间增加。当取导流口距底部距离80mm时,在滞止时间没有明显缩短的情况下,将中包平均死区比例从17.47%降低到11.47%。In order to make the flow characteristics of liquid steel in the tundish of Tiangang six strand caster more reasonable,hydraulics physical simulation experiment was conducted when the distance from diversion hole to bottom was110,80,60and30mm.Experiment results showed that with the decrease of distance from diversion hole to bottom,the proportion of tundish dead zone reduced and residue time increased.When the distance from diversion hole to bottom was80mm,under the condition of no obvious shortening of residue time,the proportion of tundish dead zone dropped from17.47%to11.47%.
