为了提高镍渣利用效率,进行了金川镍渣3种配比（全镍渣,镍渣：红土矿为7∶3,镍渣：红土矿为5∶5）的烧结杯试验,并对试验结果进行了分析。试验表明：采用全镍渣进行烧结,控制适宜条件,即焦粉配比为8%左右,混合料水分质量分数为3.5%-4.5%,烧结矿可满足要求;配入红土矿可进一步提高烧结矿各项指标;且随着红土矿配比的增加,应增大配炭量和混合料水分。

Effect of Nickel Slag on Sinter Properties

The sinter pot test were carried out in order to use Jinchuan nickel slag efficient. The proportion of nickel slagwere designed according to 100% nickel slag, 70% nickel slag plus 30% laterite and 50% nickel slag plus 50% laterite.The results indicate that the sinter quality could meet the requirements when 100% nickel slag were sintered by adoptingsuch sintering parameters as sintering blend moisture being 3.5% - 4.5% and coke breeze being 8%. The sinter quality willimprove with the increasing of laterite proportion, but the blend moisture and coke breeze need to be increased accordingly.
