含铁尘泥球团成型用复合黏结剂开发及应用

转底炉直接还原工艺具有有价元素收得率高、杂质脱除程度高的优势,成为钢铁企业含铁尘泥处理技术发展的趋势之一。但由于含铁尘泥成球性能差,导致制备出的含铁尘泥球团强度低,易粉化,严重制约了转底炉工艺的绿色高效生产。选择优良的黏结剂是改善球团原料性能和提高球团矿产质量的重要手段。通过有机黏结剂和膨润土搭配制备出复合黏结剂,探究了复合黏结剂对球团冷态性能和还原性能的影响。研究表明,复合黏结剂球团表现出优异的生球性能,其中CB2-3组(3%膨润土+0.5%黏结剂B)的生球落下强度及抗压强度分别达到8.5次/0.5 m和78 N/P,这是由于有机黏结剂含有丰富的—OH、—COO—等含氧基团,改善了含铁尘泥表面的亲水性,强化了膨润土与尘泥颗粒间的连接。黏结剂C在干燥过程会形成网状结构,促进尘泥颗粒间相互靠近,这是CB3组(3%膨润土+2%黏结剂C)干球强度提升的重要因素。同时,有机组分的增加有助于铁、锌氧化物的还原反应,主要原因是有机组分高温下热解,在球团内部形成微小孔隙,加快了燃料的热解和还原产物的扩散,促进还原反应的正向进行,但生成的过量孔隙会导致球团强度下降。工业试验表明,相较于现场使用的复合黏结剂YG-1,添加CB2-3和CB3后,可明显提高含铁尘泥球团的产质量指标,同时黏结剂成本由140元/t分别降至115元/t和120元/t,达到提质降本的效果。

FeOx-CeO2 mixed oxides with increasing Fe/（Ce＋Fe） atomic ratio （1-20 mol%） were prepared by sol-gel method and characterized by X-ray powder diffraction （XRD）, Brunauer-Emrnett-Teller （BET） and Hydrogen temperature-programmed reduction （H2-TPR） techniques. The dynamic oxygen storage capacity （DOSC） was investigated by mass spectrometry with CO/O2 transient pulses. The powder XRD data following Rietveld refinement revealed that the solubility limit of iron oxides in the CeO2 was 5 mol% based on Fe/（Ce＋Fe）. The lattice parameters experienced a decrease followed by an increase due to the influence of the maximum solubility limit of iron oxides in the CeO2. TPR analysis revealed that Fe introduction into ceria strongly modified the textual and structural properties, which influenced the oxygen handling properties. DOSC results revealed that Ce-based materials containing Fe oxides with multiple valences contribute to the majority of DOSC. The kinetic analysis indicated that the calculated apparent kinetic parameters obey the compensation effect. The three-way catalytic performance for Pd-only catalysts based on the Fe doping support exhibited the redundant iron species separated out of the CeO2 and interacted with the ceria and Pd species on the surface, which seriously influenced the catalytic properties, especially after hydrothermal aging treatment.
