<p>Provided is a structure for a tuyere section in a blast furnace, the structure for a tuyere section being capable of preventing gas leakage, assimilating disparity in furnace body side/circular pipe side thermal deformation, and maintaining the position of the tip-end of a tuyere at a specific position in the blast furnace. The structure (20) for a tuyere section in a blast furnace is provided with: a blow pipe (31) which is fixed to a shell (21); a tuyere (32) which is fixed to the tip-end of the blow pipe (31); and a flexible joint (34) which connects the blow pipe (31) and a tuyere stock (33). A tuyere section stave cooler (23) is placed on the inside of the shell (21) at the periphery of the tuyere (32), the stave cooler (23) forming the inner surface of the furnace.</p> |
