Practices on Reducing Solid Fuel Consumption in 2# Sintering Workshop of Iron-making Plant of Baotou Steel
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 propor-tion of anthracite and coke powder;effective material layer thickness is increased and automatic heat storage effect is im-proved 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.
