In the paper, the current situation of higher solid fuel consumption for 2# sintering machine in 2# Sintering Workshop of Iron-making Plant of Baotou Steel is systematacially analyzed. The fuel with comprehensive particle size>5 mm is controlled at 15%~20% and that with comprehensive particle size<1 mm is controlled at about 30% through classifying different fuel bands, putting them into tank and crushing them as well as controlling reasonable proportion of anthracite and coke powder; effective material layer thickness is increased and automatic heat storage effect is improved through increasing height of baffle for trolley of sintering machine to 750 mm and reducing thickness of bed charge from 85 mm to 70 mm; overdamp layer of sintering is reduced through reducing moisture of sinter mixture from 7.2% to 6.9%. The solid fuel consumption in 2# sintering workshop is reduced significantly through taking the above measures. It reached 50.33 kg/t in 2023, which is 2.13 kg/t lower than that in 2021, which lays the foundation for further reducing energy consumption in working procedure before iron-making.
