シール板１０に作用しないようにする。 In the cooling device of the present invention, after installing the cooling cylinder 4, the companion flange 5c to which the gas seal pipe 9 is attached in advance is fixed to the tube seat flange 5a, and then the gas seal pipe 9 and the rear end of the cooling cylinder are A gas seal plate 10 made of a thin plate is welded between the gas seal plate 6 and the gas seal plate 6 to perform gas sealing. Note that the contact surfaces of the lower support member 7 and the upper bracket 8 for supporting the cooling cylinder rear end 6 are processed to be flat, so that even if the cooling cylinder 4 is not installed horizontally, the cooling cylinder rear end 6, the lower support member 7, and the upper support member 8 are designed so that at worst they are in line contact. In addition, the gap between the steel skin tube seat 5 and the cooling cylinder rear end 6 is filled with a monolithic refractory 12,
Hot air in the furnace is prevented from directly acting on the tube seat 5, gas seal tube 9, and gas seal plate 10.

As explained above, according to the blast furnace body cooling system of the present invention, the supporting capacity of the cooling cylinder is greatly improved compared to conventional cooling systems, and the expansion force due to thermal expansion of the refractory and the ore receiving body are greatly improved. Even when a load is applied to the cooling cylinder, it is possible to avoid gas leakage due to deformation of the flange portion due to insufficient strength of the cooling cylinder support portion. Therefore, it becomes possible to maintain the blast furnace walls stably for a long period of time. In addition, the structure of the cooling tube support device of the present invention can be used not only when renovating a blast furnace, but also as a support device for cooling pipes embedded in the walls of blast furnaces to extend the life of the blast furnace. It contributes to extension, and its effect is cumulative.
