Description
Technical field
The present invention relates to a kind of blast furnace iron outlet groove tap drain water-cooled device and installation and application, belong to blast furnace storage ferrum technology neck
Domain.
Background technology
Blast furnace iron outlet groove is requisite facility in blast furnace iron-making process, and it primarily serves the purpose of the slag that buffering ferrum mouth sprays
Ferrum, and realize slag sluicing system, finally respectively the slag isolated and ferrum are delivered to ladle and flushing cinder granulation facility.Either big
Type blast furnace such as 4500m3Or small-sized 450m3Blast furnace, its basic role is not changed in.Its structural material system experienced
Ramming mass drought ditch arrives the non-irrigated ditch of pouring material and pours iron storage type major groove to present main flow.Life-span was extended to by original 1～2 week
Present 1～3 month.
But safeguard from each major groove and be still the task of very expending time and efforts, the especially work of stokehold workman
Intensity is still very big, is faced with high temperature, dust, noise, coal gas, mechanical wounding equivalent risk.In line with the principle that people-oriented, still
Need to find and extend the approaches and methods that major groove tries out the life-span.Say the non-renewable fire proofed wood of more environmentally-friendly saving from the angle of environmental protection
The requirement of material resource is also very urgent.
Content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of blast furnace iron outlet groove tap drain water-cooled device and installs and uses
Method, by this safer cooler construction effectively, realizes significantly improving of iron tap channel service life of refractory material.With significantly
Degree reduces repair rate, runs offer basis steadily in the long term for blast furnace, and then the work of stokehold iron runner maintenance work is greatly reduced
Intensity.Make the installation of iron storage type major groove cooler simultaneously and change more simple.
A kind of blast furnace iron outlet groove tap drain water-cooled device, is made up of metal seamless tube, ceramic metal and steel plate, by metal seamless
Pipe serves as coolant cycle heat exchange passage, and, as intermediate thermal conductivity body and seamless pipe protective layer, the back side is by steel plate system for ceramic metal
Cavity body, for distribution lines, and forms the space of opposing open.
A kind of blast furnace iron outlet groove tap drain water-cooled device, can with single-piece using can also more than one piece from length direction serial or parallel connection
Use.
A kind of blast furnace iron outlet groove tap drain water-cooled device installation and application；Containing cooler making step, installation steps and
Pour step,
Cooler making step: first by metal seamless tube as cooling water pipeline, by the way of filling out husky hot bending
It is processed into loop back dress, afterwards the metal seamless tube through bending is fixed to the cavity structure surface being made up of steel plate, then
It is cast into metal seamless tube protective layer using ceramic metal using the mode pouring molding；
Tap drain water cooler structure completes, and dries through more than 500 DEG C after ceramic metal solidification, in exclusion ceramic metal
It is to be installed that Free water can transport scene etc. to；
Installation steps: during installation, the material in original iron runner is removed, afterwards cooler is fixed in ditch, install iron runner
Inner mold for casting, cooler can be installed to centre position or the mould about 300mm apart from major groove center of one side；
Pour step: apparatus above fixation can start to pour iron runner castable after finishing.
After material feeding solidification to be poured, open the cover plate of water cooler chamber portion, link cooling water pipeline, sensor signal lines
Deng.
When using multiple cooler, both can connect and can also be linked using modes such as parallel connections in the way of using series connection,
After the completion of connection, major groove is toasted and is come into operation.
The ruuning situation of Sensor monitoring cooler can be passed through in operation, in case of emergency, can be by water inlet pipe
Compressed air is accessed on road, open outlet conduit, is blown into compressed air and drains the aqueous water in cooler.
During normal work, heat can be transferred to ceramic metal by relatively thin iron runner castable, then is transferred to by ceramic metal
Recirculated cooling water in cooler, is taken away by cooling water, forms heat passage.
Reduce tap drain resistance to material operating temperature, improve the purpose of corrosion resistance, highest improves iron runner service life, fall
Low frequency of maintenance.
The basic structural formula of the present invention is to form cooling water circulation passage using seamless pipe bending, using cermet material
Pour protective layer using the form pouring in seamless pipe periphery, using ceramic-metallic be to consider ceramic-metallic heat-resisting quantity
Can, make ceramic metal as the protective layer resisting high temperature protection cooling line, utilize ceramic-metallic high heat conduction characteristic simultaneously, can
Using as good heat transfer medium.
In addition pass through steel plate and form cavity at the cooler back side, the space in cavity is used for installing connection cooling pipe, temperature
Degree sensor etc., cavity is as non-close space simultaneously, the problems such as will not produce blast when there is extreme case, indirectly carries
High major groove tries out the safety of water cooler.
And installation site aspect is adjusted to water cooler position, conventional tap drain water-cooled is typically in iron storage type major groove
Outside, it is contemplated that traditional general heat conductivity of iron runner material is relatively low.
In this case, in traditional design theory, iron runner material thickness generally reaches more than 600mm, at most can reach
1200mm, therefore thermal resistance are larger, and the thermal resistance that heat must pull against iron runner material can be only achieved water cooler, and therefore effect is extremely limited,
Heat flux is difficult to improve it is desirable to it is relatively difficult for reaching preferable intensity of cooling, and after using a period of time, iron runner side
After wall thickness is thinning, although cooling effectiveness can be improved, due to not had other can hold outside cooler
By the refractory material protective layer of high-temperature liquid state molten iron, therefore in the event of extreme case, leakage ferrum can be produced, often consequence is extremely tight
Weight.
Therefore general use habit be iron runner resistance to material thickness of the liner degree be thinned to less than 300mm i.e. start repair liner iron runner resistance to
Tap drain cooler is therefore installed to the nearly inner side near blast furnace iron outlet groove major groove, makes cooler come into operation it in iron runner by material
Just start to play larger work efficiency, continue setting safe floor or referred to as permanent layer outside cooler, as guarantor simultaneously
Shield, had therefore both improve the using effect of cooler, also very high safety.
It is an advantage of the invention that proposing the structure design of blast furnace iron outlet groove water cooler, solve existing tap drain water-cooled effect
The drawbacks of rate is low or safe not enough, it is possible to increase the service life of blast furnace iron storage type major groove, to install more convenient simultaneously.
Basic structure of the present invention is to serve as coolant cycle heat exchange passage by seamless pipe, and ceramic metal is as intermediate thermal conductivity body
And seamless pipe protective layer, the back side, by steel plate hollow cavity, for distribution lines, and forms the space of opposing open, it is to avoid envelope
Close the various hidden danger that space leads to.Present configuration is simple, safe, can effectively improve the use longevity of blast furnace iron outlet groove
Life.The disposable iron of existing blast furnace iron outlet groove ideally can be made to improve several times, or under the equal operating mode of great prolongation
Life-span on probation.
