| abstract | (57) [Summary] [PROBLEMS] To improve tapping temperature, secure slag fluidity, and improve coke temperature to improve reducibility and melting property. SOLUTION: In a hearth portion of a coke packed bed type vertical furnace 1 having two tuyeres 3 and 4 in upper and lower stages and filling coke 2, slag 11 is retained and coke 2 A gas inlet 13 is provided at a portion where the packed bed is continuous to the hearth, that is, at least at a position that does not vertically overlap with the tuyere 4 at the lower stage, from which a supporting gas such as oxygen or hot air is blown. Thus, the coke 2 in the slag 11 is burned to generate heat, and by heating the slag 11, the pig iron 10 and the coke 2 are also heated by heat transfer. Below the lower tuyere 4 Since the packed layer of coke 2 is divided by the raceway 12 and the coke 2 is floating on the slag 11, the effect is small. |
