Abstract

在本文中，提出了一种新形式的倾斜底吹气体方法，以增强顶底复吹气体系统下的熔池混合过程。建立了欧拉-欧拉模型来描述260 t转炉简化模型的顶底复吹过程。通过对比数值模拟结果与文献中的实验结果验证了模型的准确性。然后基于相似理论将实际转炉进行缩小，并在此基础上进行数值模拟。详细讨论了底吹角度对熔池混合效率、流动特性和炉衬磨损的影响。数值模拟结果表明，随着底吹角度的增大，混合时间先减小后增大。当底吹角度为5°~ 6°时，熔池混合时间最短。通过壁面剪切应力表征炉衬磨损情况，指出了在新形式底吹方式下炉衬主要的磨损位置。壁面剪切应力随角度的变化极小，这表明新形式底吹并不会加剧炉衬磨损。
