摘要综述了近年来国内外高炉球团矿使用比例的现状,分析了球团矿化学成分控制以及不同化学成分对球团矿冶金性能的影响。分析表明,多数国内钢铁企业球团矿TFe的质量分数较低,SiO₂质量分数较高且差异较大。不同企业球团矿Al₂O₃和FeO的质量分数不同。应控制球团矿中SiO₂、Al₂O₃和FeO的质量分数。随着CaO和MgO质量分数的提高,球团矿抗压强度均降低。适宜质量分数的CaO有利于改善球团矿的还原膨胀性能。随着MgO质量分数的提高,球团矿的还原膨胀性和软熔滴落性能均变好。高炉炉料结构采用低MgO烧结矿、酸性球团矿和镁质球团相结合,可以充分发挥球团矿的冶炼优势,实现球团矿入炉比例的提高。MgO和CaO在球团矿焙烧过程中的作用机理,以及如何控制镁质球团中的液相含量以提高球团矿的抗压强度等需要进一步深入研究。

Abstract：The proportion of pellets used in the blast furnaces at home and abroad in recent years were investigated. And the pellets chemical composition in different conditions were analyzed as well as its effects on the metallurgical properties of pellets. It is pointed out that the pellets produced by most of domestic steel enterprises possess low TFe mass percent and high SiO₂ mass percent with larger fluctuation. The mass percent of Al₂O₃ and FeO varies greatly in different enterprises. The mass percent of SiO₂、Al₂O₃and FeO should be controlled further. The pellet compress strength decreases with the increase of CaO and MgO mass percent. CaO with appropriate mass percent can improve the reduction expansibility of pellets.The increase of MgO mass percent can improve the reduction expansibility and softening-dripping performance of pellets. The combination of low MgO sinter, acidic pellet and magnesium-bearing pellet can sufficiently exploit the advantages of pellet metallurgical properties to realize the increase of pellet proportion used in blast furnace. The function mechanism of MgO and CaO in pellet baking process should be studied in detail, and how to control the content of liquid phase in magnesium-bearing pellet should be also investigated further in order to improve the pellet compress strength.

Key words： pellet chemical composition metallurgical property charge structure magnesium-bearing pellet
