Abstract (en)

[origin: EP3712281A1] A device for controlling a blast in a blast furnace includes: an imaging device for capturing an image of a charging material charged into the blast furnace; at least one sensor for measuring a condition of the blast furnace; a data collector for obtaining particle size data of the charging material from the image; a blast volume predictor for obtaining a blast volume predictive value of the blast furnace from the particle size data; and a blast volume controller for controlling a hot-blast volume supplied into the blast furnace according to the blast volume predictive value.
