摘要
介绍了近年来攀钢高炉提高钒钛磁铁矿比例的强化冶炼技术,通过优化烧结原料结构和高炉炉料结构,强化高炉操作,提高焦炭质量等技术措施,有效改善了入炉原燃料质量和炉料的冶金性能,强化了高配比钒钛矿冶炼。在入炉品位50%左右,取得了较好的冶炼技术经济指标,年平均利用系数达到了2.4～2.5 t/(m3.d)。
Technologies of increasing proportion of vanadium-bearing titanomagnetite used as feedstock for BF smelting at Pangang are introduced.By optimizing sintering material structure and BF burden structure,strengthening BF operation,and upgrading coke quality,the quality of raw material and fuel into blast furnace and metallurgical properties of burden were drastically improved,and intensified smelting with higher proportion of vanadium-bearing titanomagnetite as feedstock for BF was achieved.Based on 50% grade of burden,desirable technical and economic indices were achieved,with annual average utilization coefficient reaching 2.4～2.5 t/（m3·d）.
