摘要/Abstract

摘要： 基于相似理论,利用1:9水模型研究了钢包吹氩钢水中夹杂物的物理行为,试验了不同底吹位置下吹气时间2～28 min、吹气量(1.19～4.75)×10^-2m³/h对夹杂物去除行为的影响。结果表明,较小吹气量在8 min内可将绝大部分的模拟夹杂物去除,而较大吹气量时,中心和偏心喷吹方式分别需要20 min和16 min;不管中心还是偏心喷吹方式,去夹杂效果均随吹气量的增加先增大后减小,且存在一个最佳去夹杂吹气量;较小吹气量范围内,偏心喷吹方式的去夹杂效果要优于中心喷吹方式,而较大吹气量范围内则相反。

Abstract: Based on analogy theory, the physical behavior of inclusion in liquid steel of ladle with argon stirring lias been studied by using 1; 9 water model and the effect of gas injecting time 2 ~28 min and gas flow-rate ( 1. 19 ~4. 75) x 10^-2m³ with different bottom blowing position on inclusion removal was tested. Results showed that most of inclusions could be removed in 8 min with smaller gas flow-rate, but with larger gas flow-rate that was In 20 min and 16 min respectively by using central blowing mode and eccentric blowing mode; by using either central or eccentric blowing mode, with increasing gas flow-rate, the inclusion removal rate increased at beginning, then decreased, and there was an optimum gas flow-rate for removal inclusions: with smaller gas flow-rate, the inclusion removal effect with eccentric blowing mode was better than that with center blowing mode, while with larger gas flow-rale the effect was opposite.
