Abstract: Characteristics of liquid field in tundish with the straight and curved weir and dam in common use and the new optimized straight and curved weir and dam with guiding flow tube device have been studied by using 1: 3 water model and numerical simulation. Results showed that average residence time, response time and peak time of liquid steel at nozzle increased by using optimized device in tundish, and difference of maximum residence time of liquid steel between each nozzle decreased in some extent which obviously improved metallurgy effect in tundish.

摘要： 采用1:3水力学模型和数值模拟研究了常用的直和圆弧形导流墙结构和新型优化直和圆弧形导流墙加导流管结构的中间包钢水流场的特性。结果表明,优化的中间包结构提高了水口处钢水平均停留时间、响应时间和峰值时间,各个水口之间钢水的最大停留时间的差别也有所减小,明显改善了中间包的冶金效果。
