Description
Technical field
The present invention relates to stove construction technical fields, and in particular to a kind of group's hot-blast stove on-bne repair refractory material transport
Device and repair method.
Background technique
Blast furnace is the capital equipment of ironmaking, and hot-blast stove is one of main auxiliary device of blast furnace, is fired using blast furnace gas
The heat of burning provides the hot wind of high temperature by the heat exchange action of checker brick for blast furnace.Therefore, every seat height furnace is commonly equipped with 3 ~ 4
Seat hot-blast stove, so as to combustion heating and air-supply alternately operation.
Since hot-blast stove produces throughout the year, some checker brick fragmentations are serious, and a large amount of fragments are fallen down, and checkerwork cell blocking amount is larger, sternly
Thermal Efficiency of Hot Blast Stoves is affected again, therefore, is needed periodically to checker brick, partition wall transformation maintenance.When maintenance, hot-blast stove is successively examined one by one
It repairs.However, how to guarantee that blast furnace normally produces during maintenance, and build, the refractory material removed is transported, is transported is hot wind
The difficulties of furnace on-bne repair.

Stretch out be opened in spherical vault 40 towards day hole, cross bar 25 is by U-shaped card 26 and is mounted on towards the flanged joint on day hole 41.
For the ease of installing and removing hoisting apparatus and platform inside furnace in furnace, furnace is installed on the top platform 44 of hot-blast stove
Push up handling apparatus.As shown in Figure 1 and Figure 5, furnace roof handling apparatus includes door shaped stent 29, in door shaped stent 29 and the second pylon 6
Horizontal the second monorail 30 and the second electric block 31, the second monorail 30 and the second electric block 31 are installed between top
For the refractory material out of hot-blast stove the furnace towards after being removed hoisting apparatus and platform inside furnace in transport furnace in day hole 41.
The present invention also provides a kind of group's hot-blast stove on-bne repair refractory material repair method, main includes following step
It is rapid:
Step 1: blowing out: it include four hot-blast stoves in the present embodiment, the maintenance of checker brick 39, partition wall 38 in each hot-blast stove
By the sequence of 3# hot-blast stove 34,4# hot-blast stove 35,2# hot-blast stove 33,1# hot-blast stove 32, blowing out is promoted one by one；In hot wind after blowing out
The hot-blast valve of each pipeline of furnace, flue bent pipe valve, combustion air valve, adds blind plate at cold blast sliding valve at gas valve, and wherein hot air pipe exports
The blind plate back side will add reinforcing rib, need to use three layers of (700mm wide) firebreak of lightweight brick masonry in hot air pipe before blind plate installation, pacify
Washer is added when dress prevents gas leakage；Cooling is forced after the temperature of hot-blast stove spherical vault 40 is down to 200 DEG C or less, is such as opened
Cold wind is blasted towards day hole 41, at the lower part manhole of hot-blast stove；
Step 2: setting up the transportation system: hoisting apparatus and furnace roof handling apparatus in the outer transport device of installation furnace, furnace,
Wherein, the outer transport device of furnace include one layer of construction, 1, two layer of plane construction plane 2, operation platform 10(bottom operation platform
Installation slagging-off chute 15 on 10), the first vertical transporting mechanism 3 and the second vertical transporting mechanism 4 etc.；
Step 3: removing former refractory material in hot-blast stove and being transported to outside furnace: removing the fire proofed wood in hot-blast stove from top to bottom
Material is opened the construction hole 16 former construction hole 16(and opened up when newly building furnace body, applied using original when tearing open to construction 16 position of hole
Work hole 16 is to reduce the aperture patch of furnace shell 36)；Partition wall 38 is removed using pneumatic pick and crowbar, is needed before dismounting to ceramic burner
Device carries out covering protection, and reinforces to the partition wall of reservation 38 every 5 meters (vertical directions)；Brick slag after dismounting divides in hot-blast stove
Choosing is packaged, in case subsequent recovery utilizes；Biggish brick slag is transported to the designated place heap of one layer of construction plane 1 through transport device outside furnace
It puts, tiny brick slag is sent through the slagging-off chute 15 of operation platform 10 to 42 outside of flue bent pipe of one layer of plane 1 of constructing, by first
Railcar 14 is sent to open ground, then is packed into automobile tipping bucket with loading machine and is transported outside the venue；
Step 4: transporting new refractory material: by the automobile used for refractory material that need to be built from the whole container in warehouse (or packaging
Case) it is transported to one layer of construction plane (fork truck handling), and stacked by kind, specification classification, make eye-catching mark；And use vertical transport
The new refractory material of needs is transported in furnace by hoisting apparatus and furnace roof handling apparatus from one layer of construction plane in mechanism, furnace specifies block
Build place；
Step 5: building checker brick 39: checker brick 39 with seam at 1-8 layer to build, and three kinds of arrangements replace since the 9th layer
Build, the 9th layer of code when it is levelling and with fire grate checkerwork cell to good, after complete 9 layers of code, correct checkerwork cell with the steel pipe that diameter is 38 millimeters,
Groove should be beaten before steel pipe；It to be stayed between checker brick 39 and furnace wall (vertical big-wall 37 and partition wall 38) and set expansion joint (E.J.), expansion joint (E.J.) size is
25 millimeters or so；When need to build vertical big-wall 37,39 surface of checker brick is covered tightly with rubber, prevents checkerwork cell from blocking, periphery lattice
39 scene of sub- brick is processed with hand, and when processing should pad fritter rubber skin；Checker brick 39, but wood must be fixed with timber wedge every three layers
Wedge not beaten too tight, and checker brick 39 is avoided to shift；Most upper six layers of code is at platform is pushed away, and every layer of combustion chamber side is moved back one piece, the good grid of code
Grid control line should be pulled on when brick 39；
Step 6: building partition wall 38: partition wall template unwrapping wire is simultaneously positioned using " ten " word, and partition wall template school is utilized when masonry
Just；It builds partition wall 38 alternately to build with code checker brick 39, first builds 1 meter high partition wall 38, then build 1 meter of high checker brick
39；
