分析了添加剂对内配煤高铁赤铁泥团块还原焙烧的作用，建立了还原动力学模型──收缩未反应核模型，探讨了添加剂对渣铁分离的影响，并最终获得了了一种新的高效“Ｏ”型添加剂。
The effect of additives on the reduction roasting of the iron-bearing hematite agglomerates in the internal blending coal was analyzed. The kinetic model of reduction - the contracting unreacted nuclear model was established and the influence of additives on the separation of slag and iron was discussed. Finally, a new Efficient “O” additive.
