Response Measures and Effects of Shanxi Jianlong 5# BF Coal Ratio Tackling
In January 2023,the blast furnace was compared with the industry's advanced level,and there was a gap of 40.0～50.0 kg/t in coal ratio.From February to March,the coal ratio research was launched.By taking measures such as increasing the strength of the sintered ore drum,increasing the oxygen enrichment rate,adjusting the structure of the furnace material and coke,strengthening the screening of the furnace,and optimizing the slag and thermal systems,the final coal ratio reached and remained stable at 175.0 kg/t with an increase of 22.1 kg/t compared with that in January,a reduction of 56.07/t in fuel costs,and a daily output increase of 181.61 tons/day,achieving the goal of increasing production and reducing costs.
