Application of Brazilian MBR lump ore in No.2 Ironworks of Tangshan Iron and Steel Co. Ltd.

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.
