摘要: 为定量描述熔炼过程中乳化现象,首先建立了基于相似原理的物理模型,然后使用高分辨率相机和Image Pro-Plus 6.0软件考察了气体流量对熔池内乳化层的形成、乳化液滴尺寸分布的影响规律,最终建立了传质界面面积ɑ的估算方法.结果表明:乳化液滴的体积表面积平均直径值(SMD)随着气体流量的增大而减小,乳化层内ɑ值随着气体流量的增大几乎呈线性增长,铜锍与渣的分离可由重力和扩散传质引起.

Abstract: In order to quantitatively describe the emulsion phenomena, a physical model was built up based on the similarity law. Then a high-resolution camera and Image Pro-Plus 6.0 software were utilized to record the emulsion phenomena and analyze the effect of gas flow rate on the emulsified drops size distribution. Finally, an estimation method of the interfacial area ɑ was given. The results show that the Sauter mean diameter (SMD) of emulsified drops decreases with the increasing of gas flow rate. The interfacial area of emulsion layer almost linearly increases with the gas flow rate and the separation of matte and slag is caused by gravity and mass transfer.
