ABSTRACT:
A connecting structure of a blast furnace hot stove of the type in which a heat accumulation chamber dome and a combustion chamber dome are directly connected to each other through a dome connecting pipe which does not have any expansion joint. The ratio (RD/TD) of the diameter (RD) of the dome connecting pipe to the diameter (TD) of the heat accumulation chamber dome approximately meets the condition wherein 0.24.ltoreq.(RD/TD).ltoreq.0.60, while the ratio (RD/ND) of the diameter (RD) of the dome connecting pipe to the diameter (ND) of the combustion chamber dome approximately meets the condition wherein 0.44.ltoreq.(RD/ND).ltoreq.0.80. The connecting structure may have a reinforcement ring provided on straight barrel portions immediately under the heat accumulation chamber dome and the combustion chamber dome, and a connecting beam may be fixed at one end to one of the reinforcement rings and engage at its other end with the other of the reinforcement rings for limited sliding motion. The connecting structure may further have a reinforcement member provided in each of the regions where the dome connecting pipe is connected to the heat accumulation chamber dome and the combustion chamber dome.
