At present,the main process of sintering production in China is thick layer sintering,which plays a significant role in improving the quality index of sintered minerals,reducing energy consumption and reducing CO2 emissions.Finally,through a series of process improvements,the material layer height of the 3# sintering machine was increased from 720 mm to 860 mm.After the material layer height was increased,the sinter drum strength was increased by 7.08％,the ore return rate was reduced by 0.53％,and the utilization coefficient was increased to more than 1.55 t/(m2·h),solid burn-up was reduced to 57.64 kg/t.
