Production Increase and Consumption Reduction Efforts Amid Raw Material and Fuel Quality Deterioration in Hanbao Steel 3200 m3 BF
Hanbao Steel 3200m3 BF had the problems of unsmooth central gas flow and unstable edge gas flow as the raw ma-terial and fuel quality deteriorated.Besides the unsatisfactory running status,its main techno-economic indicators regress greatly and the production cost increases significantly.By taking the measures such as improving the quality of raw material and fuel,conditioning the burden distribution system,and optimizing the blasting operation system,slagging system and blow off/reblow on operation as well,the furnace runs much smoothly.Both the blast flow rate and oxygen enrichment rate hike,the furnace stability and interference resistance enhance,and the main techno-economic indicators improve greatly.In No-vember 2022,the daily output of the furnace hits 8705t/d,the fuel rate drops to 507.3kg/t,and the production cost reduces significantly.
