摘　　要：研究了石灰活性对烧结矿中铁酸钙的结晶形态及数量的影响。用扫描电镜分析了不同活性度石灰的形貌,并对配加不同活性度石灰的烧结矿进行了矿相分析。结果表明:石灰活性影响烧结矿中铁酸钙的结晶形态及铁酸钙数量,活性度高的石灰有利于细针状和针状铁酸钙的形成。　The influence of the lime＇s activities on the form and amoumt of calcium ferrite has been studied in this paper.The patterns of the different lime were characterized by SEM.The specimens of sintering were characterized by reflex microscope.The results have shown that the high activity of the lime is favorable for the formation of fine acicular and acicular structure calcium ferrite.
