The influence of some factors on velocity field in continuous casting tundishes has been veri- fied by means of computer simulation.These factors are tundish wall inclination;the dimensionless geometric size of tundish,the double inclined wall tundish;the dimension and location of weir and dam.

通过选择乳状液滴模拟夹杂物和连铸中间包水模型实验, 考察了控流装置、浇铸速度
及夹杂物粒径对中间包内夹杂物去除行为的影响规律. 结果表明: 挡墙-挡坝组合控
流去除夹杂物效果最佳, 中间包内强湍流区夹杂物的碰撞、聚合以及向上和表面流速的
增加是主因; 中间包注流区加入冲击槽, 虽然其流体流动特征发生改变, 但对夹杂物
去除率的影响并不显著; 浇铸速度较高时, 仅靠控流装置的优化已不能很好地改
善夹杂物的去除效果.
