Abstract
A kind of thin-skinned lining blast-furnace bosh structure, belongs to blast-furnace technique field in metallurgical industry.Including bosh copper cooling wall, air port cooling wall inlays brick, and bosh is laid bricks, tuyere combined brick and tuyere medium sleeve；Bosh copper cooling wall is vertical section in air port cooling wall top, bosh copper cooling wall bottom, and vertical section has bosh to lay bricks on hot face；Bosh copper cooling wall top Xie Duanre faces set edge brick；Being built on the inside of the cooling wall of air port has tuyere combined brick, is tuyere medium sleeve inside tuyere combined brick.Advantage is, it is ensured that the enough thickness of tuyere combined brick, to maintain rational bosh angle, is conducive to bosh coal gas smoothly to arrange liter；Coal gas of high temperature fast flush is reduced to corrode；Effectively extend the bosh life-span.
Description
Technical field
The utility model belongs to blast-furnace technique field in metallurgical industry, more particularly to a kind of thin-skinned lining State of Blast Furnace fu jie
Structure.
Background technology
Modern blast furnace is more and more to use full cooling wall thin-skinned lining structure, and obvious reduction trend is presented in bosh angle,
Because furnace lining is thinned, such as according to traditional burner abdomen cooling wall, then cooling wall bottom can be caused to stretch into excessive in stove, wind is thinned significantly
Mouth modular tile thickness.And bosh position is in furnace charge and declined and the most active high temperature melting tabetisol of coal gas motion, for a long time by high temperature
And thermal shock impact, first slagging and molten iron are corroded, alkali metal and zinc corrode, furnace charge abrasion and Gas Flow wash away and CO2And H2O's
Oxidation, working environment is severe, often the region of blast fumance badly broken, easily occurs cooling wall breakage accident, right
Life of the blast furnace influence is huge.
The content of the invention
The purpose of this utility model is to provide a kind of thin-skinned lining blast-furnace bosh structure, solves cooling wall cracky
Problem.To form rational bosh angle, extension blast-furnace bosh position service life.
A kind of thin-skinned lining blast-furnace bosh structure, including bosh copper cooling wall 1, air port cooling wall 2 inlay brick 3, bosh is laid bricks
4, tuyere combined brick 5, tuyere medium sleeve 6；Bosh copper cooling wall 1 is on the top of air port cooling wall 2, and the bottom of bosh copper cooling wall 1 is perpendicular
There is bosh to lay bricks 4 on straight section, the hot face of vertical section；The top Xie Duanre faces of bosh copper cooling wall 1 set edge brick 3, inlay the trypsin method of brick 3；Wind
The inner side of mouth cooling wall 2, which is built, tuyere combined brick 5, and the inside of tuyere combined brick 5 is tuyere medium sleeve 6.
The inclination angle that the top Xie Duanre faces of bosh copper cooling wall 1 are formed coincide with bosh angle as far as possible, should not occur too big
Deviate；The lower vertical of bosh copper cooling wall 1 section is with the top of air port cooling wall 2 to be hot in face of neat.
On tuyere combined brick 5 along thickness be 320~360mm.
The utility model has the advantage of, the thin-skinned lining bosh bending copper cooling wall bottom provided is set to vertical section,
The enough thickness of tuyere combined brick is ensure that, to maintain rational bosh angle, is conducive to bosh coal gas smoothly to arrange liter；Air port group
Close the bosh at brick and copper cooling wall bottom straight section to lay bricks preferable protection stove belly position cooling wall and tuyere medium sleeve, reduce it
Coal gas of high temperature fast flush corrodes.After bosh top bricking disappearance, formed cohere stable slag crust as early as possible, protection cooling wall is exempted from
It is damaged, it is to avoid the problems such as the premature breakage water pipe leak of bosh cooling wall bottom, effectively the extension bosh life-span.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.Wherein, bosh copper cooling wall 1, air port cooling wall 2 inlays brick 3, bosh
Lay bricks 4, tuyere combined brick 5, tuyere medium sleeve 6.
Embodiment
Fig. 1 is embodiment of the present utility model.
A kind of thin-skinned lining blast-furnace bosh structure, including bosh copper cooling wall 1, air port cooling wall 2 inlay brick 3, bosh is laid bricks
4, tuyere combined brick 5, tuyere medium sleeve 6；Bosh copper cooling wall 1 is on the top of air port cooling wall 2, and the bottom of bosh copper cooling wall 1 is perpendicular
There is bosh to lay bricks 4 on straight section, the hot face of vertical section；The top Xie Duanre faces of bosh copper cooling wall 1 set edge brick 3, inlay the trypsin method of brick 3；Wind
The inner side of mouth cooling wall 2, which is built, tuyere combined brick 5, and the inside of tuyere combined brick 5 is tuyere medium sleeve 6.
The inclination angle that the top Xie Duanre faces of bosh copper cooling wall 1 are formed coincide with bosh angle as far as possible, should not occur too big
Deviate；The lower vertical of bosh copper cooling wall 1 section is with the top of air port cooling wall 2 to be hot in face of neat.
On tuyere combined brick 5 along thickness be 350mm.
The utility model blast-furnace bosh structure is not limited only to described in embodiment, is additionally included in the hot face of oblique section of copper cooling wall 1 straight
Connect spraying and replace edge brick 3.
