武钢烧结厂生产过程中产生的粉尘经回收处理得到的除尘灰和除尘精矿品位较低,Fe O、Si O2和有害杂质的含量较高。在基准配矿条件下,分别用2%、4%、6%、8%的除尘灰取代混匀粉进行烧结试验,结果表明,除尘灰取代混匀粉时,烧结过程各项指标均变好。用6%除尘精矿、除尘灰分别取代混匀粉时,配除尘精矿的烧结速度和利用系数较差,但成品率和转鼓强度稍好。 The dust generated during the production of the WISCO sinter plant is of low grade by dust collection and dedusting, and the contents of Fe O, Si O 2 and harmful impurities are high. Under the condition of benchmark mineralization, the mixed powder was replaced by 2%, 4%, 6% and 8% dust respectively for sintering test. The results showed that when the dust was replaced by the mixed dust, the indexes in the sintering process became better . With 6% dust concentrates, dust were replaced by mixing dust, dust concentrate with sintering speed and utilization factor is poor, but the yield and drum strength slightly better.
