| 摘 要： | 论述了球团矿质量对气基竖炉直接还原生产和DRI质量的影响以及DRI质量对炼钢生产的影响.介绍了提高气基竖炉直接还原工艺用球团矿质量的技术,包括降低Si02含量、降低粘结趋势、提高还原性和提高大粒度(12.5～16.0 mm)球团比率等措施及其发展.指出若把低TFe、高脉石含量的高炉用球团矿直接用于气基直接还原竖炉,至少应该采用球团涂层技术；如果球团矿脉石含量较高,需要借助工业试验进行综合分析以确定其经济性.

| Abstract: | The effect of pellet quality on gas-based direct reduction shaft production and DRI quality and the effect of DRI quality on steelmaking production were discussed.The technologies of improving gas-based direct reduction pellet quality were also presented,which include measures such as reducing SiO2 content,decreasing pellet sticking trend,increasing reducibility and proportion of pellet with size(12.5~16.0 mm) etc.It was pointed out that,if blast furnace pellet with low TFe and high langue are directly used in gas-based direct reduction shaft,pellet coating techniques should be applied at least,if langue content of pellet is higher,comprehensive analysis should be carried out through industrial test to ascertain its economy. |
