摘　　要：在马钢一烧2座8m2 竖炉上进行了配用巴西PF精矿的工业性试验。试验结果表明,在膨润土用量不变的情况下,配用8%和1 5 %巴西PF精矿替代巴西CVRD精矿,其生产操作和球团矿的常规质量指标变化不大。冶金性能检验表明,配用巴西PF精矿的球团矿,除低温还原粉化变差导致压差略有升高外,还原性、还原速率、还原膨胀、熔滴性能的变化不大。This paper introduces commercial experiments of PF concentrate pelletizing in two sets of 8m 2 shaft at Maanshan Steel's No.1 Sinter Shop. In the case of same bentonite addition and using 8% and 15% PF concentrate to replace CVRD concentrate, the operation and pellet quality indexes were kept nearly no change. In addition, no obvious changes were observed in metallurgical properties, such as reducibility, reduction rate, expansion after reduction, except for a little worse of RDI index and pressure difference.
