选择乳状液滴作为模拟夹杂物,利用物理模型研究了偏心底吹氩钢包内夹杂物的物理行为,考察了时间、吹气量对夹杂物去除行为的影响规律。结果表明,较小气量在8 min内可将绝大部分的模拟夹杂物去除,而较大气量则需要16 min才能去除绝大部分的模拟夹杂物,所有气量在28 min内可将能够去除的模拟夹杂物几乎全部去除。在相对较短的吹气处理时间内,较小气量的去夹杂效果要优于较大气量。总体上看,存在一个获得去夹杂较佳效果的气量范围。
The emulsion droplets were selected as the simulated inclusions. The physical behavior of inclusions in the eccentric bottom blown argon ladle was studied by physical model. The influence of time and air inflow on the inclusion removal was investigated. The results show that most of the simulated inclusions can be removed within a period of 8 min, while the larger one takes 16 min to remove most of the simulated inclusions. All of the gasses can be removed within 28 min Almost all simulated inclusions are removed. In a relatively short blow treatment time, the smaller amount of entrained impurity effect is better than the larger amount of gas. In general, there is a range of volumes that give the best effect of de-occlusion.
