摘　　要：为了研究细颗粒含铁料在马钢烧结的处理及高效利用的途径,特针对马钢多种冶金固废、低品位铁精矿、细颗粒含铁料的理化性能、亲水性、成球性等进行深入研究,提出了将细颗粒含铁料造小球,开展小球烧结的试验,探索细颗粒含铁料合理、高效利用的途径。试验结果表明,与常规高比例细颗粒含铁料烧结方法相比,细颗粒含铁料小球混合烧结的垂直烧结速度、生产率与基准相当,烧结矿转鼓强度和成品率上升,固体燃耗下降,细颗粒含铁料在烧结的利用得到了很好优化。In order to study the fine particles of iron in the way of comprehensive treatment and utilization in masteel sintering, especially for masteel a variety of solid waste, low grade concentrate, such as the physical and chemical properties, hydrophilic, a thorough investigation into a ball, etc, put forward fine particles of iron balls, carry out small ball sintering experiment, explore comprehensive treatment and utilization ways of fine particles of iron. The experimental results show that compared with the conventional sintering method for high proportion fine particles containing iron, the vertical sintering speed and productivity of fine particles mixed sintering are comparable with the reference, the sinter drum strength and yield increase, the solid fuel consumption decreases, and fine particles iron sintering is optimized. It has been proved that the pellet sintering of fine iron particles is an effective way to rationally and efficiently utilize such fine particle irons as metallurgical dust and mud and concentrate.
