ABSTRACT:
An apparatus for changing the charge distribution in a blast furnace is constituted by a large number of arms disposed in a circle in the top of the furnace, the upper end of each arm being attached to the shell of the furnace through a link so as to be tiltable relative to the shell, a plate fixed to the lower portion of the arm and facing toward the center of the furnace, and a mechanism including a push rod for inclining the arm with respect to the axis of the furnace in a direction for pushing the lower portion of the arm toward the furnace center. The link, arm and push rod make up a link mechanism. The linear motion of the push rod expands the paired link and arm and inclines the plate while pushing the plate inward.
