摘要 通过物理模拟实验研究了在不同的中间包液位时使用喇叭形长水口和直通形长水口对单流板坯中间包内的流体流动特性的影响。实验结果表明:使用喇叭形长水口后的RTD曲线峰值较低,波动较小,流场较稳定,而且不存在短路流;使用喇叭形长水口后更有利于延长流体在中间包内的开始响应时间、平均停留时间和活塞流平均停留时间;中间包内的死区体积较小,活塞流体积较大,而且活塞流与死区体积的比值也更大。因此,在中间包液位上升时,使用喇叭形长水口后包内的流动模式组成更合理,这更有利于保证中间包内钢水的质量。 The influence of trumpet-shaped ladle shroud and straight ladle shroud on characteristics of fluid flow in a single strand slab tundish under different liquid levels through physical simulation is studied.The results show that the peak value of RTD curves after using trumpet-shaped ladle shroud is relatively low,the curves become smooth,the flow field is relatively stable and there isn't short circuit flow.Also,the respond residence time,the mean residence time and the plug residence time of the liquid in tundish are prolonged.Besides,when the trumpet-shaped ladle shroud is used,the dead volume fraction is smaller,the plug volume fraction becomes larger and the ratio of the plug volume fraction to the dead volume fraction is greater.Therefore,when the liquid level of tundish is going up,its flow pattern becomes more reasonable after using trumpet-shaped ladle shroud,which is in favor of improving the quality of molten steel in tundish.
