摘要
Provided are a method for charging a raw material into a bell-less blast furnace, whereby a raw material can be charged into the furnace in a predetermined position without compromising productivity, and a blast furnace operation method which uses said raw material charging method. The present invention provides a method for charging a raw material into a bell-less blast furnace, the method comprising causing a distribution chute to turn and charging an iron-source raw material and a carbon material into the blast furnace, wherein the distribution chute has a rebound plate inclined downward from the conveyance direction of the distribution chute, at the distal end of the distribution chute, and the turning speed of the distribution chute is greater than 10 rpm.
