Description
Technical field
The present invention relates to a kind of blast furnace iron outlet groove tap drain water cooling device and installation and applications, belong to blast furnace storage iron technology neck
Domain.
Background technique
Blast furnace iron outlet groove is essential facility in blast furnace iron-making process, and main function is the slag for buffering iron mouth and spraying
Iron, and realize slag iron separation, the slag isolated and iron are finally delivered to ladle respectively and flushing cinder is granulated facility.It is either big
Type blast furnace such as 4500m3Or small-sized 450m3Blast furnace, basic role do not change.Its structural material system experienced
Ramming mass drought ditch pours iron storage type major groove to pouring material drought ditch to present mainstream.Service life extended to via original 1~2 week
Present 1~3 month.
But very the expending time and efforts of the task, the especially labour of stokehold worker are still from the maintenance of each major groove
Intensity is still very big, is faced with the risks such as high temperature, dust, noise, coal gas, mechanical wounding.In line with people-oriented principle, still
It needs to find and extends the approaches and methods that major groove tries out the service life.The more environmentally-friendly non-renewable fire proofed wood of saving is said from the angle of environmental protection
Expect that the requirement of resource is also very urgent.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of blast furnace iron outlet groove tap drain water cooling device and installs and uses
Method realizes significantly improving for iron tap channel service life of refractory material by this safer effectively cooler construction.With substantially
Degree reduces repair rate, runs steadily in the long term for blast furnace and provides basis, and then the labour of stokehold iron runner maintenance work is greatly reduced
Intensity.Keep the installation and replacement of iron storage type major groove cooler more simple and easy simultaneously.
A kind of blast furnace iron outlet groove tap drain water cooling device, is made of metal seamless tube, cermet and steel plate, by metal seamless
Pipe serves as coolant liquid cycle heat exchange channel, and cermet is as intermediate thermal conductivity body and seamless pipe protective layer, and the back side is by steel plate system
Cavity body is used for distribution lines, and forms the space of opposing open.
A kind of blast furnace iron outlet groove tap drain water cooling device can be used with single-piece also with more than one piece from length direction serial or parallel connection
It uses.
A kind of blast furnace iron outlet groove tap drain water cooling device installation and application；Containing cooler making step, installation steps and
Step is poured,
Cooler making step: use metal seamless tube as cooling water pipeline first, by the way of filling out husky hot bending
It is processed into loop back dress, the metal seamless tube Jing Guo bending is fixed to the cavity structure surface made of steel plate later, then
Metal seamless tube protective layer is cast into using the mode of pouring molding using cermet；
Tap drain water cooler structure is completed, and is dried, is excluded in cermet by 500 DEG C or more after cermet solidification
It is to be installed that Free water can transport scene etc. to；
Installation steps: removing the material in original iron runner when installation, and cooler is fixed in ditch later, installs iron runner
Inner mold for casting, the mold about 300mm or so that cooler can be installed to unilateral middle position or hit exactly apart from major groove；
Pour step: apparatus above fixation can start to pour iron runner castable after finishing.
After material feeding solidification to be poured, the cover board of water cooler chamber portion is opened, cooling water pipeline, sensor signal lines are linked
Deng.
When using multiple coolers, concatenated mode both can be used connects or can be used the modes such as parallel connection and linked,
Major groove is toasted and is come into operation after the completion of connection.
In operation can by sensor monitor cooler operating condition 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 liquid water in cooler.
Heat can be transferred to cermet by relatively thin iron runner castable when normal work, then be transferred to by cermet
Recirculated cooling water in cooler, is taken away by cooling water, forms heat passage.
Reaching reduces the resistance to material operating temperature of tap drain, improves the purpose of corrosion resistance, and highest improves iron runner service life, drop
Low frequency of maintenance.
Basic structural formula of the invention is to form cooling water circulation passage using seamless pipe bending, uses cermet material
Protective layer is poured on seamless pipe periphery using the form poured, what it is using cermet is the heat-resisting quantity for considering cermet
Can, make cermet as the protective layer for resisting high temperature protection cooling line, while using the high thermal conductivity characteristic of cermet, it can
Using as good heat transfer medium.
Furthermore cavity is formed at the cooler back side by steel plate, the space in cavity is for installing connection cooling pipe, temperature
The problems such as spending sensor etc., while cavity is as non-close space, will not generating explosion when extreme case occurs, indirectly mentions
High major groove tries out the safety of water cooler.
And water cooler position is adjusted in terms of installation site, previous tap drain water cooling is usually in iron storage type major groove
Outside, it is contemplated that traditional general thermal coefficient of iron runner material is lower.
In this case, iron runner material thickness generally reaches 600mm or more in traditional design theory, at most can achieve
1200mm, therefore thermal resistance is larger, the thermal resistance that heat must overcome iron runner material can be only achieved water cooler, therefore effect is extremely limited,
Heat flux is difficult to improve, it is desirable to and it is relatively difficult for reaching ideal intensity of cooling, and after using a period of time, iron runner side
After wall thickness is thinned, cooling efficiency although available raising, but due to can have been held without other on the outside of cooler
By the refractory material protective layer of high-temperature liquid state molten iron, so if extreme case occurs, leakage iron can be generated, often consequence is extremely tight
Weight.
Therefore general use habit is that the resistance to material liner thickness degree of iron runner is thinned to less than 300mm that start repairing liner iron runner resistance to
Material, therefore tap drain cooler is installed to close to the nearly inside of blast furnace iron outlet groove major groove, so that cooler is come into operation it in iron runner
Just start to play biggish working efficiency, while continuing on the outside of cooler to be arranged safe floor or for permanent layer, as guarantor
Shield, therefore had both improved 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, solves existing tap drain water cooling effect
The drawback that rate is low or safety is insufficient can be improved the service life of blast furnace iron storage type major groove, while installation is more convenient.
Basic structure of the present invention is that coolant liquid cycle heat exchange channel is served as by seamless pipe, and cermet is as intermediate thermal conductivity body
And seamless pipe protective layer, the back side is used for distribution lines by steel plate hollow cavity, and forms the space of opposing open, avoids sealing
Close various hidden danger caused by space.The configuration of the present invention is simple, highly-safe, can effectively improve blast furnace iron outlet groove uses the longevity
Life.It so that the disposable iron of existing blast furnace iron outlet groove is improved several times, or greatly extend under same operating condition
Service life on probation.
