摘　　要：钢铁企业在钢铁生产过程中不可避免的产生许多以铁为主要成分的含铁尘泥。本文对不同含铁尘泥进行理化性能分析,并就使用磁铁矿粉配加含铁尘泥生产球团进行了试验性研究。试验结果表明:随着含铁尘泥配比的降低,生球抗压强度、落下次数和焙烧球团抗压强度均有所改善;使用磁铁矿粉配加10%的含铁尘泥,焙烧球团抗压强度可以达到2 500 N/个以上;含铁尘泥配比在15%时,降低含碳尘泥的配比,可以有效提高焙烧球团抗压强度。Iron -containing dusts and sludges is inevitably produced in iron and steel production. In this paper, physical and chemical properties analysis of the iron - containing dusts and sludges was performed, and study on the pellets production with iron - containing dusts and sludges was implemented. The results show that： the strength of green and roasting pellets increase as the ratio of dusts and sludges decrease; compressive strengths went over 2 500 N/P when 10% dusts and sludges was added; while adding 15% dusts and sludges, compressive strength could be improved by lowering the ratio of carbon containing dusts.
