概略介绍生泥综合利用的研究结果。含铁尘泥合理利用途径主要取决于尘泥的物化性质。对于铁品位低,Zn,Pb等有害杂质含量不高的含碳尘泥,造成小球加入烧结配料的小球烧结法是一条经济有效的途径。含Zn,Pb等有害元素较高的尘泥,生产高炉用还原球团是一条较彻底的尘泥利用途径。对于高铁品位尘泥可用于生产高金属化率直接还原铁(DRI)作为废钢代用品,这不仅可有效回收高品位尘泥,同时可缓解废钢短缺,是一经济效益较高的途径。
A brief introduction of the research results of comprehensive utilization of raw mud. The rational use of iron-bearing dust and mud depends on the physical and chemical properties of dust. For low-grade iron, Zn, Pb and other harmful impurities in the low content of carbonaceous dust, resulting in the ball to join the sintering ingredients of the ball sintering method is a cost-effective way. Containing Zn, Pb and other harmful elements higher dust, reducing the production of blast furnace pellets is a more thorough use of dust. For high-speed rail grade dust sludge can be used to produce high metallization rate DRI as a scrap substitute, which not only can effectively recover high-grade dust, but also can ease the shortage of scrap, which is a highly economical way.
