Al2O3是高爐煉鐵爐渣的重要成分之一,隨著Al2O3含量的不斷升高,爐渣流動性差、脫硫能力下降等問題日漸突顯,對高爐冶煉造成極大危害。針對這一問題,***上普遍采用的應對方式是在燒結工藝中添加MgO。然而,如何添加,添加多少***合適,卻是一道***難題。

2015年,我國1000 m3以下高爐渣的平均鎂鋁比約為0.68,1000~3000 m3高爐渣的平均鎂鋁比約為0.60,3000 m3以上高爐渣的平均鎂鋁比約為0.55~0.57。較高的鎂鋁比不僅增大了渣量、能耗及鎂資源的消耗,同時也影響燒結生產及燒結礦的質量。因此,研究燒結-高爐各環節適宜的MgO含量和高爐渣中適宜的MgO/Al2O3比例顯得十分必要。

MgO如何添加才能做到優化?
