摘要
为保证料层厚度由600 mm提高至1000 mm后,烧结生产稳定顺行,通过烧结杯实验,研究了料层厚度及水碳结构对料层透气性和烧结矿质量的影响。优化后烧结产能及质量得到改善,垂烧速度、转鼓指数和整体利用系数由15.2 mm/min、65.0%和1.23 t/(m^(2)·h)提高至22.3 mm/min、68.9%和1.54 t/(m^(2)·h)。确认了现场烧结原料结构下的最佳配水量为7.5%,同时不降低固体燃料用量,为超厚料层烧结稳定生产提供了数据指导。
In order to ensure that the sintering production is stable after the thickness of the material layer is increased from 600 mm to 1000 mm,the effects of the thickness of the material layer,the amount of water and carbon on the permeability of the material layer and the quality of the sinter are studied by the sintering cup experiment.After optimization,the sintering capacity and quality were significantly improved.The vertical sintering speed,drum index and overall utilization coefficient increased from 15.2 mm/min,65.0%and 1.23 t/(m^(2)·h)to 22.3 mm/min,68.9%and 1.54 t/(m^(2)·h),respectively.It is confirmed that the optimal water distribution under the site sintering raw material structure is about 7.5%without reducing the solid fuel consumption,which provides data guidance for the stable production of ultra-thick layer sintering.
