摘要
采用CFD软件FLUENT对6流中间包内的流场进行了数值模拟,分析了6流中间包内的流场特征,以及有无C型挡墙的加入,中间包内流场的变化情况。模拟结果表明,C型挡墙的加入使6流中间包各流的流动更加均匀,有利于钢液温度和成分的均匀;C型挡墙的加入使6流中间包近流的平均停留时间增加,利于夹杂物的上浮去除。
The flow field of six-strand tundish was simulated using fluid dynamics package FLUENT. The characteristics of six-strand tundish flow field are analysed. The path lines of fluid and flow field in tundish are compared on the condition of tundish with C shape weir or without weir. The simulation results show that the liquid steel among outlets is homogeneous with the join of C shape weir, which is favourable for the inclusion removal. The results are essential for optimizing the dam and weir parameters of simstrand tundish.
