In order to ensure that the sintering production is stable after the thickness of the material layer is increased from 600 mm to 1 000 mm,the effects of the thickness of the material layer,the a-mount 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 sig-nificantly improved.The vertical sintering speed,drum index and overall utilization coefficient in-creased from 15.2 mm/min,65.0% and 1.23 t/(m2·h)to 22.3 mm/min,68.9% and 1.54 t/(m2·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.
