Abstract

See full text

Disclosed is a blast furnace apparatus includes: a rotating chute; a profile measurement device configured to measure surface profiles of a burden charged into the furnace; and a tilt angle controller configured to control a tilt angle of the chute, in which the device includes a radio wave distance meter installed on the furnace top and configured to measure the distance to the surface of the burden, derives the profiles on a basis of distance data for the entire furnace obtained by scanning a detection wave of the distance meter in the furnace in a circumferential direction, and includes at least one of arithmetic units configured to command during rotation, on a basis of the surface profiles obtained, the controller to change the tilt angle of the chute, or a controller to change a rotational speed of the chute or a feed speed of the burden fed to the chute.
