摘　　要：在烧结工序能耗中,固体燃耗(焦粉和无烟煤)占70%~80%,降低固体燃耗是降低烧结工序能耗的关键。文章针对包钢265 m^(2)烧结机固体燃耗偏高的问题,结合现有原料、燃料条件,通过设备改造、优化工艺操作、强化生产管理等措施,降低烧结机漏风率到35%,提高烧结料层的有效高度到780 mm;通过修订烧结外购燃料的采购标准,降低了烧结外购焦粉<1 mm粒级的占比,从修订前的41.02%降低至修订后的22.72%,改善了烧结燃料粒度组成。综合以上措施,2023年包钢265 m^(2)烧结机固体燃耗降低至50.75 kg/t,较2021年降低了1.70 kg/t。In the energy consumption of sintering process,solid fuel(powdered coke and anthracite)consumption accounts for 70%~80%,so it is the key to reduce solid fuel consumption for reducing energy consumption of sintering process.In the paper,it is introduced the air leakage rate of sintering machine is decreased to 35%and effective height of sinter bed is increased to 780 mm through such measures as equipment transformation,optimizing technological operations and strengthening production management combining with the existing conditions of raw materials and fuels aiming at the problem of higher solid fuel consumption for 265 m^(2)sintering machine of Baotou Steel;proportion of size fraction of outsourced powdered coke<1 mm for sintering is decreased from 41.02%to 22.72%through revising the purchase standard of outsourced fuels for sintering so that size composition of fuel for sintering is improved.The solid fuel consumption for 265 m^(2)sintering machine of Baotou Steel was reduced to 50.75 kg/t in 2023 through the above measures,which was 1.70 kg/t lower than that in 2021.
