Description
Technical field
The present invention relates to the auxiliary equipment of a kind of electric furnace, be specifically related to the cooling section of a kind of electric furnace gasification cooling flue.
Background technology
The gasification cooling flue of electric furnace is to realize one of energy recovery and the green necessaries produced, and it is for by electricity
The flue gas produced in stove steelmaking process cools down and reclaims.The most domestic gasification cooling flue is from the first paragraph of electric furnace side
(i.e. cooling section) is an entirety, and such design have ignored the Temperature Distribution in flue, and flue extends to inner side from import
The position on arc top is high-temperature area, and maximum temperature can reach 1300 DEG C, and following position is middle gentle low-temperature region, and temperature exists
Between 800 DEG C-1000 DEG C.The service life of normal gasification cooling flue was up to 4 years, and the life-span of high-temperature area can be only sustained at
2 years, do not carry out independently considering to damageable zone, relatively reduce the service life of flue.
Summary of the invention
The present invention provides the cooling section of a kind of electric furnace gasification cooling flue so that the high-temperature area of flue is relatively independent, when
It can process after breaking down at short notice, and can change damageable zone in time, reduces maintenance load and maintenance
Cost.

300mm。
The cooling section of described electric furnace gasification cooling flue, its preferred version is, water screen tube one and water screen tube two
Quantity is at least 108.
The invention have the benefit that
1, the present invention carries out subsection setup by the cooling section of electric furnace gasification cooling flue so that flue from import to inner side
The position (i.e. high-temperature area) extending to arc top is relatively independent, can process at short notice after it breaks down, and can be to easily
Damage position to change in time, reduce maintenance load and maintenance cost.
2, the cooling water pipeline in the present invention is optimised, and the leading portion of cooling section, back segment carry out independent water distribution circulation, by growing
Distance many groups loop optimization becomes short distance list group to circulate so that its cooling effect is ensured, extends the service life of flue.
3, on the water inlet pipe one in the present invention, flow control valve one is set, water inlet pipe two arranges flow control valve two, side
Just the distribution being circulated the water yield adjusts, it is possible to ensureing that the output of leading portion is suitably above the output of back segment, cooling effectiveness obtains
To improve.
