The fuel ratio is the main economic and technical index for blast furnace ironmaking, so it is of great significance for energy conservation and emission reduction of enterprise to reduce it. In this paper, the reasons for high fuel ratio of 6^# blast furnace of Baotou Steel are analyzed. After the overhaul and blow-in of 6^# blast furnace, the fuel ratio of blast furnace is reduced through taking such measures as tackling key problems in improving production to stabilize the feed of blast furnace, improving quality of raw fuel, strictly controlling differential pressure in blast furnace operation, adjusting charging system, stabilizing high blast temperature, reasonable use of enriched oxygen and coal injection as well as strengthening basic management. The cumulative fuel ratio in 2021 was 545.84 kg/t, which was 10.58 kg/t lower than that in 2020.
