Abstract：Nanjing steel No.3 BF cancel center plus coke smelting process to evaluate and summarize the practice, especially for loading and air system for continuous research and exploration, by raising the temperature of the furnace core and stable within a reasonable range, so that the hearth has been remain active in working condition. By stable and reasonable operating furnace premise and gradually reducing the amount of coke center plus significantly improved gas flow distribution, improved the gas utilization, fuel ratio is greatly reduced and achieved good economic benefits. Our canceled central focus experience as the theoretical foundation successfully extended to the other blast furnace.
