Abstract
A surface profile detection apparatus of a burden in a blast furnace includes a rotating plate mounted immediately above an opening part of the blast furnace and configured to rotate about an opening center of the opening part as a central axis, a rotating means for rotating the rotating plate, and a transmission and reception means for transmitting a detection wave such as a microwave or a millimeter wave in a linear shape along a diametrical direction of the rotating plate and receiving the detection wave. The surface profile detection apparatus performs transmission and reception in a direction orthogonal to a rotating direction of the rotating plate while rotating the rotating plate in synchronization with turning of the shooter so that transmission of the detection wave is not interrupted.
