PURPOSE: To improve the raw material charging capacity in a blast furnace by adjusting the space between the raw materials to be conveyed by a belt conveyor in the case of storing the same raw materials continuously and in the case of charging separate materials into furnace top hoppers.
CONSTITUTION: In the stage of deliverying charging raw materials from hoppers 1AW1D on the ground onto a belt conveyor 2, it is assumed that, for example, the charge partterns C, C↓, C↓, O, O↓ are incorporated. The first C, C are stored continuously into the same furnace top hopper 4B and therefore the space l1 between the coke C1 to be conveyed first and the coke C2 to be conveyed in succession to the coke C1 on the conveyor 2 is substantially unnecessary. However, the coke C3 to be conveyed next is charged independently of the portion by one time into the hopper 4A and therefore it is necessary to provide a space l2 between the coke C3 and the coke C2. In the stage of delivering ore O, a space between the same and the coke C3 is required but there is no need for a transport spacing between the ores O and O.
