Technical field
The present invention relates to a kind of blast furnace taphole region cooling structures, belong to blast furnace in metallurgical industry ironmaking equipment technical field.
Background technology
The iron mouth region domain of blast furnace belongs to the more region of heat exchange, and a large amount of slag iron will pass through this region daily
It is discharged into outside stove.The iron mouth of general blast furnace and forms refractory brick using the laying fireproof bricks structure of pottery by cast
The integrated poured bed of material is equipped with cast iron or cast copper smooth surface cooling wall, the master of this structure in the outside of the integrated poured bed of material of refractory brick
It is that heat-conducting effect is bad, and iron mouth region domain occurs since the brickwork joint of iron mouth region domain modular tile is more, after blow-on and runs to want problem
The phenomenon that coal gas, is commonplace.Especially the later stage, to be susceptible to side wall temperatures below the air port of the both sides Tie Kou again higher in a furnace
Problem influences the service life of entire blast furnace.
Invention content
It is an object of the present invention to provide a kind of blast furnace taphole region cooling structures, can improve the heat transfer effect in blast furnace taphole region
Rate extends the service life of blast furnace, solves the problems, such as background technology.
The technical scheme is that：
A kind of blast furnace taphole region cooling structure, including the integrated poured bed of material of refractory brick, carbon brick and cooling wall, in blast furnace taphole area
Domain is equipped with the integrated poured bed of material of refractory brick, and the outside of the integrated poured bed of material of refractory brick is equipped with cooling wall, and cooling wall is whole with refractory brick
Between body cast bed of material be equipped with carbon brick, the cooling wall to the side of carbon brick be equipped with multiple parallel arrangements floor, adjacent two
Between a floor be equipped with multiple copper-bar coolers, carbon brick be equipped with on cooling wall floor and the matched groove of copper-bar cooler and
Copper-bar cooler hole.
Floor on the cooling wall is strip, and the copper-bar cooler on cooling wall is cylinder.
The cooling wall is equipped with copper-bar cooler mounting hole, and copper-bar cooler is fixed in copper-bar cooler mounting hole.
It is filled using carbon ramming mass between the cooling wall and carbon brick.
The side of the cooling wall matrix towards carbon brick is the hot face of cooling wall, and the other side opposite with the hot face of cooling wall is cold
But wall huyashi-chuuka (cold chinese-style noodles).
Between the carbon brick and the integrated poured bed of material of refractory brick together by castable cast.
Using the present invention, the quantity of the floor and copper-bar cooler that are arranged in parallel on cooling wall can be according to cooling wall area
Size depending on, 0.2-0.5 times of heat transfer area can be increased by multiple floors on cooling wall, copper-bar cooler can be substantially
Improve the heat transfer efficiency in iron mouth region domain.It is filled using carbon mud between cooling wall and carbon brick, can prevent air gap from occurring, ensured
Heat-conducting effect.
The beneficial effects of the invention are as follows：0.2-0.5 times of heat transfer area can be increased, improve the heat transfer in blast furnace taphole region
Efficiency extends the service life of blast furnace.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is cooling wall structure schematic diagram of the present invention；
In figure：The integrated poured bed of material 1 of refractory brick, carbon brick 2, groove 3, copper-bar cooler hole 4, cooling wall 5, copper-bar cooler mounting hole 6,
Floor 7, copper-bar cooler 8.
Specific implementation mode
Below in conjunction with attached drawing, by example, the invention will be further described.
With reference to attached drawing 1,2, a kind of blast furnace taphole region cooling structure, including the integrated poured bed of material 1 of refractory brick, 2 and of carbon brick
Cooling wall 5 is equipped with the integrated poured bed of material 1 of refractory brick in blast furnace taphole region, and the outside of the integrated poured bed of material of refractory brick 1 is equipped with cold
But wall 5 are equipped with carbon brick 2 between cooling wall 5 and the integrated poured bed of material of refractory brick 1, side of the cooling wall 5 towards carbon brick 2 is set
There is the floor 7 of multiple parallel arrangements, multiple copper-bar coolers 8 are equipped between two neighboring floor 7, carbon brick 2 is equipped with and cooling wall 2
On floor 7 and 8 matched groove 3 of copper-bar cooler and copper-bar cooler hole 4.
In the present embodiment, with reference to attached drawing 2, cooling wall 5 is cast iron quality, and side of the cooling wall 5 towards carbon brick 5 fixes two
The floor 7 of a parallel arrangement, floor 7 are strip, are set between two floors 7 there are four copper-bar cooler mounting hole 6, four copper are cold
But stick 8 is separately mounted on four copper-bar cooler mounting holes 6, and four copper-bar coolers 8 are set in an arrangement, and copper-bar cooler 8 is in cylinder
Shape.
When construction, according to the sequence from blast furnace external-to-internal, most external of the cooling wall 5 in this structure.It is built in blast furnace
If period, after installing furnace shell, this cooling wall 5, the regular worker of entire cooling wall are fixed on the stove skin in iron mouth region domain
After completing, could start resistance to material builds work by laying bricks or stones.
When the brickwork of resistance to material, masonry heater bottom first after the completion of bottom construction is built by laying bricks or stones, could start iron mouth region domain and entire cupola well
Build work by laying bricks or stones.In iron mouth region domain, the inside of already installed cooling wall 5 builds carbon brick 2 by laying bricks or stones, and carbon brick 2 uses ultramicropore carbon brick,
Carbon brick 2 be equipped with the 7 matched groove 3 of floor of strip and with 8 matched copper-bar cooler hole 4 of copper-bar cooler, build by laying bricks or stones
After completion, complete circular carbon brick setting is formed in the height in cupola well iron mouth region domain.
After carbon brick 2 builds completion by laying bricks or stones, start resistance to material in stove builds work by laying bricks or stones.The refractory brick in the blast furnace taphole region
The integrated poured bed of material 1 be common pottery laying fireproof bricks structure, and after the completion of the laying fireproof bricks of pottery again into
Row cast.
One-piece casting pottery liner is used in iron mouth region domain, and in the inside for the ultramicropore carbon brick completed according to pouring
The process implementing iron mouth region domain one-piece casting work built.After iron mouth region domain pours completion, then the ceramic body to pour is base
Point completes building by laying bricks or stones for ring-shaped pottery matter masonry.
