摘要: 通过建立的中间包钢液流动传热三维耦合数学模型,采用FLUENT软件模拟研究了H-型钢用三流异型坯连铸长水口浸入深度(100~200 mm)对36t中间包Q235B钢水(0.12%~0.20%C)流场和温度场的影响。结果表明,随长水口浸入深度的增加,中间包内钢水自由液面波动有减少趋势;中间包各流出口钢水平均停留时间差和各流钢水出口温度差显著增大;该中间包异型坯连铸过程合适的长水口浸入深度约为125 mm。

Abstract: With established three-dimensional coupled numerical models for flow and heat transfer of liquid steel in tundish, the effect of immersion depth of long nozzle (100 〜200 mm) on flow field and temperature field of Q235B liquid steel (0. 12% ~0. 20% C) in a 36t tundish during casting of three strands profiled bloom for H-shaped section has been simulated and studied by using software FLUENT. Results show that with increasing the immersion depth of long nozzle the fluctuating of free surface of liquid steel in tundish has decreasing tend and the difference of average residence time and the difference of temperature of liquid steel at tundish each strand outlet obviously increase; and the suitable immersion depth of long nozzle for the tundish during profiled bloom concasting is about 125 mm.
