ABSTRACT:
A method and apparatus for supervising a descending speed, thickness of a layer, particle size, and so on of charges in a blast furnace. Coke and ore composing the charges are detected by radiating an electromagnetic wave into the blast furnace. An electromagnetic wave can easily pass through coke, but is reflected or scattered by ore.
