| 摘 要： | 采用几何相似比1:2.5的水模型试验研究了带有一字型挡墙,矩形导流孔,水平无倾角的原型中间包以及V形挡墙,倾角0°~40°Φ80~Φ120mm圆形导流孔,并加抑制器的改进结构的流场,得出V字型挡墙+30°倾角和直径Φ80 mm导流孔+深盘带唇缘型湍流抑制器的改进中间包结构最优,可延长钢液在中间包内的停留时间,死区体积从原中间包的48.16%~63.06%降至10.3%~10.9%,有利于夹杂物的快速上浮。

| Abstract: | The flow field in original tundish with single-line type retaining wall, rectangular guide-flow-hole and level- no dip angle and in improved tundish with V- type retaining wall, Φ80 ~Φ 120 mm round guide-flow-hole and dip angle 0°- 40 °, and adding turbulence inhibitor has been tested and studied by using geometric similarity 1：2.5 water model. It is obtained that the structure of improved tundish with V- type retaining wall +30° angle and diameter Φ80 mm guide-flow- hole + deep disc-lip type edge turbulence inhibitor is optimal, it may prolong the residence time of liquid in tundish and the percentage of dead zone volume of liquid decreases to 10.3% ?10.9% from 48.16% ~63.06% in original tundish, and is in favor of inclusions in liquid to quick floating off. |
