摘　　要：以安庆含硫 1.61%的磁铁精矿为对象 ,研究了用高硫磁铁精矿制备满足高炉冶炼要求的氧化球团矿的可行性。采用含镁工业盐类矿物为添加剂 ,通过系统地试验研究 ,获得了抗压强度 2 552 N/个、含硫量 0 .0 18%、Fe O含量 1.67%、冶金性能良好的球团矿。探讨了添加剂强化高硫磁铁精矿球团氧化固结的机理。On the basis of Anqing magnetite concentrates with 1. 61% sulphur,the possibility of using high-sulphur magnetite concentrates to produce oxide pellets for BF feeding was investgated. Systematically studies indicated that , by using a magnesium- containing industrial saline mineral as additive, pelletes could be obtained with 2552N/p compression strength,0.01% sulphur,1.67% FeO,and agreeable metallurgical properties.The mechenism of the strenthening effect of the magnesium-containing additive on the oxidizing induration of high- sulphur magnetite concentrate pellets was examined.
