In this paper, the production practices of sintering with total iron ore concentrate under the condition of the self-produced iron ore concentrate of Bayan Obo as the main iron-containing raw material (85%) in Baotou Steel are elaborated. The results showed that the utilization coefficient of sintering was maintained at the original level by such measures as increasing the temperature of compound, improving the granulation effect of compound as well as adjusting the longitudinal segregation of burden distribution and the angle of the stirring machine for ensuring the gas permeability of the bed of material; the burn-up index of sintering solid was increased by 6.5 kg/t, the content of FeO in the sinter was increased and the strength of sinter was decreased by 0.15 percentage points compared with that before the practices.

文章主要阐述了在包钢以自产白云鄂博铁精矿为主要含铁原料(85%)条件下实施全精矿烧结的生产实践。结果表明:实施全精矿烧结后,为保证料层透气性,采取提高混合料料温、改善混合料制粒效果,调整布料纵向偏析以及调整松料器角度等措施,使烧结利用系数维持在原有水平;烧结固体燃耗指标升高6.5 kg/t,烧结矿FeO含量升高,烧结矿强度较实施前降低0.15个百分点。

文章主要阐述了在包钢以自产白云鄂博铁精矿为主要含铁原料(85%)条件下实施全精矿烧结的生产实践。结果表明:实施全精矿烧结后,为保证料层透气性,采取提高混合料料温、改善混合料制粒效果,调整布料纵向偏析以及调整松料器角度等措施,使烧结利用系数维持在原有水平;烧结固体燃耗指标升高6.5 kg/t,烧结矿FeO含量升高,烧结矿强度较实施前降低0.15个百分点。

In this paper, the production practices of sintering with total iron ore concentrate under the condition of the self-produced iron ore concentrate of Bayan Obo as the main iron-containing raw material (85%) in Baotou Steel are elaborated. The results showed that the utilization coefficient of sintering was maintained at the original level by such measures as increasing the temperature of compound, improving the granulation effect of compound as well as adjusting the longitudinal segregation of burden distribution and the angle of the stirring machine for ensuring the gas permeability of the bed of material; the burn-up index of sintering solid was increased by 6.5 kg/t, the content of FeO in the sinter was increased and the strength of sinter was decreased by 0.15 percentage points compared with that before the practices.
