The blast furnace is a high-temperature closed black-box reaction vessel. Its internal physical and chemical processes are characterized by strong coupling, large time delay, and multivariable heterogeneous time lags, which severely restrict the accurate prediction and closed-loop control of hot metal output. Based o...
