合理的烧结制粒可以较好地应对原料的变化,并可得到较高的烧结利用系数和较好的还原性能。通过实验研究发现,用传统的烧结制粒工艺处理像褐铁矿这类多孔的铁矿石,烧结利用系数、冷强度和还原性都下降;而采用基于原料性质的分层制粒工艺不但可以减少烧结矿过熔,而且液相流动性也得到改善,因此烧结矿强度明显提高,料层透气性增加,从而使利用系数显著提高。 Reasonable sintering granulation can better cope with the changes of raw materials, and can get a higher coefficient of sintering utilization and better reduction performance. The experimental study found that the use of conventional sintering granulation process such as limonite porous iron ore, the sintering coefficient of use, cold strength and reduction are reduced; and based on the nature of the raw material of the layered granulation process not only Reduce sinter melting over, and the fluidity of the liquid has also been improved, so the strength of sinter increased significantly, the permeability of the material layer increases, so that the utilization factor significantly increased.
