摘要
以100 t钢包为研究对象,利用物理及数值模拟手段,对其内部流场进行研究分析。结果表明,不同含气率引起截面上的密度分布差异,依靠密度差产生浮力,进而驱动钢液流动;单吹条件下,均混时间的变化与吹气钢包内的流场密切相关,采用双喷的底吹方式更加有利于发挥钢包的精炼功能。
This paper takes 100 t ladle as the research object and uses physical and numerical simulation methods to study and analyze its internal flow field.The results show that different gas rates cause the difference of density distribution on the cross section,and the buoyancy generated by difference of density drives the flow of liquid steel.Under the condition of single blowing,the variation of mixing time is closely related to the flow field in the ladle,and the double spraying bottom blowing mode is more conducive to the refining function of the ladle.
