摘　　要：为了综合利用含铁尘泥和消纳石化碱渣,开展了烧结原料中配加含铁尘泥和石化碱渣烧结杯实验研究。结果表明,配加含铁尘泥和石化碱渣有利于提高垂直烧结速度、利用系数、成品率和转鼓指数,但烧结矿中碱金属、Zn含量增加,TFe含量降低,烧结矿还原性能和低温还原粉化指数有所降低。烧结原料中配加含铁尘泥0.5%、配加石化碱渣0.05%,在满足高炉入炉原料要求的情况下,可实现含铁尘泥的资源综合利用和石化碱渣的消纳。In order to comprehensively utilize iron⁃containing dust and consume alkaline residue from petrochemical industry,a sintering pot test was conducted by adding iron⁃containing dust and the alkaline residue from petrochemical industry into raw materials for sintering.The results show that an addition of iron⁃containing dust and the alkaline residue from petrochemical industry can not only improve vertical sintering speed,utilization coefficient,yield rate and tumbler index,but also lead to increased content of alkali metals and Zn,as well as falling in the TFe content in the sintered ores.Thus,the sintered ore presents poor reduction performance,and poor low⁃temperature reduction pulverization indices.It is found that the raw material with the addition of iron⁃containing dust at an amount of 0.5%and the addition of alkaline residue from petrochemical industry at an amount of 0.05%can meet the requirement for feed to furnace,and also make it possible for the comprehensive utilization of iron⁃containing dust and consumption of alkaline residue from petrochemical industry.
