摘    要:在升温条件下进行了不同性质的煤制成的铁矿-煤压块反应实验。结果表明:反应初期主要是挥发分的析出,在还原过程中,铁矿-无烟煤压块中挥发分先将铁氧化物还原至FeO,然后硕将FeO还原到Fe。铁矿-烟煤压块中挥发分和碳能够边疆将铁氧化物还原至Fe,无烟煤和烟煤混合制成的铁矿-混合煤压块中先是烟煤中的碳将铁氧化物部分还原至Fe,然后无烟煤中的碳将剩余的FeO还原到Fe。

关 键 词:煤性质  铁矿-煤压块  反应过程  球团

Abstract:The experiment has been carried out under heating on iron ore coal briquettes containing coal of different properties The results show that the volatile in coal releases at the beginning of heating During reduction,iron oxides of iron ore hard coal briquettes is first reduced into FeO by volatile and then FeO reduced by carbon,for iron ore soft coal briquettes,iron oxides are continuously reduced into Fe by volatile and carbon For iron ore mixed coal briquettes made of hard and soft coal,the iron oxides are first reduced into Fe party by carbon of soft coal and remained FeO reduced by carbon of hard coal
Keywords:property of coal  iron ore  coal briquette  reaction
