| Abstract: | In order to reducing the fuel consumption,and seeking the burden distribution model that adapts Jinan steel＇s raw material and fuel conditions and has high strengthening level,Jinan Steel＇s 3 200 m3 blast furnace carried out optimizing burden distribution model experiment of cancelling central coke charging.The furnace conditions operated normally during the entire testing,finally forming the stable funnel charge level.Therefore,the gas utilization efficiency was increased by 2.78%,fuel ratio was decreased by 10 to 15 kg/t and the working state of the hearth was further improved. |
