摘要

中间包内钢水在自由流出过程中容易产生汇流漩涡。汇流漩涡会引起空气和钢渣的吸入

降低钢水质量。中间包内通常设有塞棒、挡墙等常用的控流装置来优化流场。以国内某厂对称四流圆坯T形中间包为研究对象

采用数学模型模拟塞棒和挡墙对中间包出水口处汇流漩涡的影响

并用水模型验证。模拟结果表明

设有塞棒和挡墙的中间包对抑制汇流漩涡的形成效果最好。

Abstract

It is easy to generate conflux vortex at the outflow of molten steel during changing tundish.The conflux vortex can lead to the molten steel to absorb slag and air

decreasing the quality of the steel.Generally

tundish should install common flow control devices

such as stopper rods and weirs

to optimize the flow field.For four-strand round billet symmetrical T-shape tundish of a domestic steel plant

mathematical simulation was adopted to understand influences of stopper rods and weirs on conflux vortex at the outlet of tundish

and it was verified with water model.The results reveal that the effect with stopper rods and weirs to inhibiting the formation of conflux vortex exhibits desirable.
