Effect of Raw Material Size on Sintering Quality
摘要
In order to improve the output and quality of sinter, the influence of the particleParticle size of the mixtureMixture on the quality of the sinter was studied. The results show that the change trend of the mixtureMixture size modelModel is consistent with the actual mixtureMixture size change trend, and the original size distribution of iron oreIron ore directly affects the final mixtureMixture size. When the average particleParticle size of the mixtureMixture is more than 4 mm, the drum strength and the yield both decrease. When the average particleParticle size of the mixtureMixture is 3.86 mm, the sinter drum strength is the highest, and when the average particleParticle size of the mixtureMixture is 4.08 mm, the sinter yield is the highest. Relying on the comprehensive technical improvement, by reducing the proportion of large-particleParticle iron oreIron ore, the normal and high temperature performance of sinter are comprehensively improved after industrial application. And the sinteringSintering utilization Coefficient is stabilized at about 1.48 t/m2 days, the daily output of the supplied blast furnace can reach 10,000 tons.
