    摘要
  • 摘要: 分析了巴西MBR塊礦的礦相結構、礦物組成及冶金性能.MBR塊礦的各項冶金性能較好,與燒結礦組成的綜合爐料在高爐內的同化過程開始溫度和結束溫度均較高,但同化速度相對減慢.唐鋼二煉鐵廠的煉鐵生產實踐結果表明,適當配用MBR塊礦,高爐入爐品位上升,礦耗降低,綜合焦比下降,鐵成本降低,高爐順行狀態良好.MBR塊礦在改善高爐綜合技術經濟指標的過程中起著重要作用.

     

    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.
