摘　　要：主要研究了烧结矿在高炉块状带的破损机制。对于高碱度烧结矿,铁酸钙和赤铁矿的还原消失对烧结矿强度的影响是正硅酸钙相变的两倍以上;对于自熔性烧结矿和酸性烧结矿,由于矿物组成中极少甚至不含有正硅酸钙和铁酸钙,所以其强度只受赤铁矿还原消失的影响。The sinter degradation mechanism in lump zone of BF was investigated.As to high basicity sinter,the influence of the reduction disappearance of calcium ferrite and hematite on sinter strength is twice higher than the phase transition of calcium orthosilicate.For self-fluxing sinter and acid sinter,there is little or even no calcium orthosilicate and calcium ferrite in mineral composition.Therefore,the sinter strength is only affected by the reduction disappearance of hematite.

关 键 词：烧结矿 强度 正硅酸钙 铁酸钙
