摘要： 在实验室条件下，研究了含硼铁精矿对巴润精矿氧化球团制备工艺及冶金性能的影响.研究表明:球团原料中外配5.0%的含硼铁精矿，可将混合料中的巴润精矿配比(质量分数)提高到40%，制备的氧化球团满足高炉冶炼要求;含硼铁精矿可增加巴润精矿氧化球团的抗压强度和降低还原膨胀率，并可降低球团的焙烧温度;当含硼铁精矿配加量(质量分数)从0增加到7.5%时，球团抗压强度从2630N·个-1上升到3709N·个-1，还原膨胀率从25.69%降低到15.53%;外配质量分数为7.5%的含硼铁精矿时，球团的焙烧温度可从1200℃降低至1150℃，巴润精矿氧化球团满足高炉生产要求.

Abstract: Under laboratory conditions， experiments on the effect of boron-bearing iron concentrate on the preparation process and metallurgical properties of oxidized Barun iron ore pellets were carried out. The results show that， when the additional addition of boron-bearing iron concentrate is 5.0%， the oxidized iron ore pellets with 40% Barun iron ore content can meet the requirements of blast furnace smelting. Boron-bearing iron concentrate can increase the crushing strength of pellets and decrease the reduction swelling rate. With increasing the additional addition of boron-bearing iron concentrate from 0 to 7.5%， the crushing strength is raised from 2630 N to 3709N， the reduction swelling rate is decreased from 25.69% to 15.53%. When the additional addition of boron-bearing iron concentrate is 7.5%， the pellets roasting temperature can be decreased from 1200℃ to 1150℃， and the quality of the oxidized Barun iron ore pellets can still meet the requirements of blast furnace smelting.
