| 摘 要： | 分析了巴西MBR块矿的矿相结构、矿物组成及冶金性能.MBR块矿的各项冶金性能较好,与烧结矿组成的综合炉料在高炉内的同化过程开始温度和结束温度均较高,但同化速度相对减慢.唐钢二炼铁厂的炼铁生产实践结果表明,适当配用MBR块矿,高炉入炉品位上升,矿耗降低,综合焦比下降,铁成本降低,高炉顺行状态良好.MBR块矿在改善高炉综合技术经济指标的过程中起着重要作用.

| Abstract: | The ore phase structure, mineral composition and metallurgical property of Brazilian MBR lump ore were introduced. Brazilian MBR lump ore has excellent metallurgical property, and both its beginning and ending temperatures of assimilation during melting are higher, however the assimilation velocity becomes a little slower. The application of MBR lump ore shows that the charge grade of BF increases, the iron ore consumption reduces, the equivalent coke ratio declines, and the cost of iron decreases with a proper mixture of Brazilian MBR lump ore. It is shown that Brazilian MBR lump ore plays an important role in improvement of BF technical and economic production indexes. |
