摘　　要：针对高钛型磁铁精矿烧结精粉率高,制粒效果差的问题,进行了不同配比活性灰替代生灰石的实验研究。结果表明,活性灰改善混合料制粒的效果明显,有利于提高烧结过程透气性,加快烧结速度,在700 mm料层情况下,活性灰配比不超过7%时,对提高烧结矿强度效果显著。In view of high concentrate rate for sintering and poor granulating effect of high titanium type magnetite concentrate, the experimental study on different proportion of active lime substituting quick lime was conducted. The results show that the effect of active lime on improving granulation of siuter mixture is obvious, which is beneficial to the improvement of sintering process permeability and acceleration of sintering speed. When the sintering bed depth is 700 mm and the proportion of active lime is not more than 7% ,the effect of active lime on improving the strength of sinter is remarkable.
