由分形理论余维相加定律,利用分散相覆盖分维数及投影关系,计算转炉复吹过程各边界条件下乳化液滴分散相的界面积。结果表明,钢滴分散相界面积主要受到顶吹条件影响,渣滴分散相界面面积受到顶底吹共同作用的影响,底吹强度的变化会明显改变渣滴分散相界面的面积。
Based on the law of extra dimension of fractal theory, the interfacial area of dispersed phase of emulsified droplets was calculated by using the fractal dimension and projection relationship of dispersed phase. The results showed that the interfacial area of dispersed droplets was mainly affected by the top blowing conditions. The interfacial area of the dispersed droplets was affected by the combined effect of top and bottom blowing. The change of bottom blowing strength obviously changed the interface area of the dispersed droplets.
