METHOD FOR CHARGING COKE INTO BLAST FURNACE

PURPOSE:To make reducing gas flow to a center and to stabilize furnace condition by dividing the charge of coke into two series, concentrically charging them into a center part in the furnace and forming the continuous coke layer at the time of laminating ore and the coke in a blast furnace. CONSTITUTION:In the blast furnace 1 alternately charging the ore and the coke, the charge of coke is divided into two series, e.g. from a coke charging pipe 2 and from a bell 4. This bell 4 is used for forming the coke layer A and the above-mentioned pipe 2 is used for forming the furnace core coke layer B. Then, the coke for forming the above-mentioned coke layer B from this pipe 2 is concentrically charged into center part in the furnace on the ore layer 3 charged at the last time to be the height adding up the layer thickness of coke forming layer A charged in this time and the layer thickness of ore layer 3 charged at the next time. Successively, the coke is charged from the bell 4 so as to cover the ore layer 3 charged at the last time to form only a continuous coke layer in the center part of furnace.
