摘要
本文通过物理模拟对底吹氩钢包内夹杂物的去除过程以及非金属在钢渣界面处的分离过程进行研究。结果表明,模拟非金属夹杂物在钢渣界面的分离过程实验中可忽略水平流动钢液的影响。夹杂物的形状和顶渣是夹杂物在钢渣界面分离过程的重要影响因素。液膜是固体夹杂物比液体夹杂物更易被顶渣吸收去除的主要原因。液体夹杂物与界面之间液膜排液缓慢,阻碍了液体夹杂物进入渣层。
The removal inclusion in stirred ladle and the separation process of inclusion at steel-slag interface are investigate by physical modelling.The results indicated that the model of inclusions through the steel-slag interface in gas-stirred ladle can ignore the effect of horizontal movement of steel molten.And inclusion shape and slag are the important factors for the separation process.Meanwhile,liquid film is the main reason for solid inclusion absorbed by slag easier than liquid inclusion.The draining rate of film between liquid inclusion and steel-slag interface is slow.And the film resists liquid inclusion enter into slag.
