Abstract
The bosh zone structure of a blast furnace is a structure of a tubular bosh zone that is provided between a tuyere portion and a furnace trunk portion of the blast furnace, and has a diameter expanding upward along a vertical direction, in which the bosh zone has a ring-shaped sheet iron shell, a copper or copper-alloy bosh zone stave provided at the inner circumference of the steel iron "shell, and refractory bricks provided at the inner circumference of the bosh zone stave; the thickness of the refractory brick in the horizontal direction at the top edge position of the bosh zone is 50 mm to 250 mm; the thickness of the refractory brick in the horizontal direction at the bottom edge position of the bosh zone is 200 mm to 500 mm; and a narrow angle formed between the surface of the bosh zone stave and the horizontal plane is 75° to 82° in a cross section of the bosh zone including the axial line thereof.
