Description
Technical field
The present invention relates to stove construction technical field, and in particular to a kind of group's air stove on-bne repair refractory material transport
Device and repair method.
Background technology
Blast furnace is the capital equipment of ironmaking, and air stove is one of main auxiliary device of blast furnace, and which utilizes blast furnace gas to fire
The heat of burning, by the heat exchange action of checker brick, provides the hot blast of high temperature for blast furnace.Therefore, 3 ~ 4 are commonly equipped with per seat height stove
Seat air stove, so as to combustion heating and air-supply alternately operation.
As air stove is produced throughout the year, some checker brick fragmentations are serious, and a large amount of fragments fall down, and checkerwork cell blocking amount is larger, sternly
Thermal Efficiency of Hot Blast Stoves is have impact on again, therefore, need periodically to checker brick, partition wall transformation maintenance.During maintenance, air stove one by one is examined successively
Repair.However, how to ensure that during overhauling blast furnace is normally produced, and build by laying bricks or stones, the refractory material removed is transported, is transported is hot blast
The difficulties of stove on-bne repair.
So that height is for 49.928 meters of air stove as an example, checker brick build 39.3 meters of height by laying bricks or stones, what four air stovees were used
Totally 11000 tons or so of checker brick and partition block, the big wall brick of partial destruction need to change.On-bne repair construction main difficulty is embodied in
It is following some：
1）Dismounting amount is big, removes more than 10000 tons of refractory material；
2）Because other air stovees are also in production, equipment, structure can not possibly be moved（As hot air duct is located at the bottom of air stove）,
Feeding, discharge pylon is difficult near air stove, and transport of materials is very difficult；
3）Charging appliance cannot manually can only be had bad luck near air stove, most of removed material；
4）Because air stove is to overhaul one by one, and there is more interruption, the persistent period is long, and construction organization difficulty is larger；
5）Insulating lining is built in hot blast furnace shell by laying bricks or stones, furnace roof liner is ball-type vault, has been that monorail is installed to open up hole, can make
The entirety of spheroiding vault collapses；Monorail is installed outside furnace roof, the scope of electric block movement can only be in furnace roof towards day
Within the diameter in hole, lifting is limited in scope.

For from air stove towards refractory material in hoisting apparatus in transport stove in day hole 41 and the stove after platform inside furnace dismounting.
Present invention also offers a kind of group's air stove on-bne repair refractory material repair method, main to include following step
Suddenly：
Step one, blowing out：The present embodiment includes four air stovees, and 3# is pressed in checker brick 39, the maintenance of partition wall 38 in each air stove
Air stove 34,4# air stovees 35,2# air stovees 33, the order blowing out propulsion one by one of 1# air stovees 32；It is each in air stove after blowing out
Blind plate, wherein warm-air pipe outlet blind plate are added at the hot-blast valve of pipeline, gas valve, flue bent pipe valve, combustion air valve, cold blast sliding valve
Reinforcement will be set up in the back side, and blind plate need to use three layers of lightweight brick masonry in warm-air pipe before installing（700mm width）Firebreak, during installation
Packing ring to be added prevents gas leakage；Cooling is forced after the temperature of air stove spherical vault 40 is down to below 200 DEG C, is such as opened towards day
Hole 41, blast cold wind at the bottom manhole of air stove；
Step 2, set up the transportation system：Hoisting apparatus and furnace roof handling apparatus in the outer conveying arrangement of stove, stove are installed, wherein,
The outer conveying arrangement of stove includes one layer of construction plane 1, two layers of construction plane 2, operation platform 10（Pacify on the operation platform 10 of bottom
Dress slagging-off chute 15）, the first vertical transporting mechanism 3 and the second vertical transporting mechanism 4 etc.；
Step 3, remove in air stove former refractory material and be transported to outside stove：The refractory material in air stove is removed from top to bottom, is torn open
During to construction 16 position of hole, former construction hole 16 is opened（Construction hole 16 is opened up when body of heater is newly built by laying bricks or stones, using original construction hole 16
To reduce the perforate patch of furnace shell 36）；Partition wall 38 is removed using pneumatic pick and crowbar, needs to carry out ceramic burner before dismounting
Covering protection, and to retain partition wall 38 every 5 meters（Vertical direction）Reinforce；Brick slag after dismounting is sorted in air stove and is beaten
Bag, in case subsequent recovery is utilized；The outer conveying arrangement of larger brick slag Jing stoves is transported to the appointed place of one layer of construction plane 1 and stacks,
The slagging-off chute 15 of tiny brick slag Jing operation platforms 10 is delivered on the outside of the flue bent pipe 42 of one layer of construction plane 1, by the first rail
Road car 14 delivers to open ground, then is transported outside the venue with loader loading automobile tipping bucket；
Step 4, the new refractory material of transport：By the automobile used for refractory material that need to be built by laying bricks or stones from the whole container in warehouse（Or packing cratess）Fortune
To one layer of construction plane（Fork truck is loaded and unloaded）, and stack by kind, specification classification, make eye-catching mark；And using vertical transporting mechanism,
In stove, the new refractory material for needing is transported to specify in stove from one layer of construction plane and builds ground by laying bricks or stones by hoisting apparatus and furnace roof handling apparatus
Point；
Step 5, build checker brick 39 by laying bricks or stones：Checker brick 39 are to build by laying bricks or stones with seam in 1-8 layers, start three kinds of arrangements from the 9th layer and alternately build
Build, it is levelling during the 9th layer of code and with fire grate checkerwork cell to good, after code is complete 9 layers, with a diameter of 38 millimeters of steel pipes correction checkerwork cell, steel
Groove should be beaten before pipe；Checker brick 39 and furnace wall（Vertical big-wall 37 and partition wall 38）Between to stay and set expansion joint (E.J.), expansion joint (E.J.) size is 25
Millimeter；When need to build vertical big-wall 37 by laying bricks or stones, 39 surface of checker brick is covered tightly with rubber, prevents checkerwork cell from blocking, periphery grid
39 scene of brick is processed with handss, and fritter rubber peel should be padded during processing；Checker brick 39, but timber wedge must be fixed with timber wedge every three layers
Should not beat too tight, it is to avoid checker brick 39 are shifted；Most go up six layers of code one piece is moved back into platform, per layer of combustion chamber side is pushed away, the good checker brick of code
Grid control line should be pulled on when 39；
Step 6, build partition wall 38 by laying bricks or stones：Partition wall model unwrapping wire is simultaneously positioned using " ten " word, is corrected using partition wall model when building by laying bricks or stones；Build
