Specific embodiment
With reference to embodiments and its attached drawing further explains the present invention.
Embodiment 1
The method for maintaining that 7.63 meters of small burners of coke oven of the invention are smoldered, comprising the following steps:
Referring now to Fig. 1 and Fig. 2, Fig. 1 is the small furnace head structure schematic diagram of coke side of the embodiment of the present invention, and Fig. 2 is that the present invention is implemented
The small furnace head structure schematic diagram of pusher side of example.As shown, the outside of small 2 stoke hole 4 of burner of coke side, the small burner 2 of coke side
Inside is lined with small burner refractory brick, and grout hole 3 is equipped within the scope of the 3rd layer of refractory brick -11th layer refractory brick；It is equally small in pusher side
The inside in the outside of 2 tedge 9 of burner, the small burner 2 of coke side is lined with small burner refractory brick, in the 3rd layer of refractory brick -11th layer fire resisting
Grout hole 3 is equipped within the scope of brick.
A, the small small protection board in burner side of cokery side furnace roof is cut and disassembled
Small protection board is fixed on furnace stay using iron wire first, the small protection board top thick stick bolt that then comes loose is adopted near furnace stay
Small protection board is cut with tool.Since small protection board is thicker, when cutting, must not hurt furnace stay.To cutting after the completion of cutting
Face beats groove, convenient for welding below.
B, the small burner of cokery side furnace roof is removed
After the small protection board cutting disassembling in the small burner side of furnace roof surface railing, attached plate, cokery side, the small burner fire resisting of furnace roof is removed
Brick.Cokery side clinker tile is first removed, 4-10 floor (113, No. 114) clay brick is then removed.Then side wall and the 3rd layer of fire resisting are cleared up
Brick setting.
C, No. 114 bricks are processed, grout hole is formed
Fig. 3 is the 10th layer plane figure of coke side of the embodiment of the present invention, and Fig. 4 is the 10th layer plane figure of pusher side of the embodiment of the present invention.
4-10 floor (113, No. 114) clay brick is processed, one knife of end beveled, length 50mm;Every layer processing 4 pieces No. 114 viscous
Cob brick forms 2 grout holes, such as following figure.It is 4-10 layers, all identical as the 10th layer, ultimately form the grouting from the 4th layer to furnace roof
Hole is also convenient for post-grouting.
D, firedoor frame top cordage is removed, blowing cleans, ceramic fibre rope filling
Fig. 5 is the sealed structural schematic diagram between the firedoor frame top and burner thrust plate of the embodiment of the present invention.To firedoor frame top
Ceramic fibre rope between burner thrust plate is removed, blowing cleans, is in the milk, and is then carried out ceramic fibre rope and is dipped in mortar filling
It is closely knit.Due to the position be it is horizontal, self-control specific purpose tool be in the milk.In addition the consistency of grouting material will be more greatly.Grouting material
Using clay chamotte (KC-W), additional 2% waterglass (I class of Pyatyi or 75 °) is modulated to flow regime (specific gravity 1.5- with water
1.7 are advisable).
E, the small burner of cokery side is built
First build 113, No. 114 clay brick of 4-10 floor.It must assure that mortar is full when masonry, grouting hole is vertical, not faulting of slab ends.
Masonry appearance is smooth, not faulting of slab ends, guarantees that the small protection board installation of burner is smooth.Then it is in the milk to the grout hole of small burner, most
11th layer refractory brick and surface clinker tile are built afterwards, complete the reparation that small burner is smoldered.
The grouting material composition that the method for maintaining that 7.63 meters of small burners of coke oven of the invention are smoldered uses: furnace roof grouting is using viscous
Native chamotte (KC-W), additional 2% waterglass (I class of Pyatyi or 75 °), being modulated to flow regime with water, (specific gravity is that 1.2-1.6 is
Preferably).Grout hopper must be used by pouring into mud to grout hole, prevent mud from splashing.Each grout hole is in the milk in three times, often
Secondary time interval 1-1.5h.The 1-2 times 2 barrels every time of burner position grout hole (about 6 liter/barrel).
The present invention has substantive distinguishing features and significant technological progress, the dimension that 7.63 meters of small burners of coke oven of the invention are smoldered
It repairs method and removes the small protection board of small burner of coking furnace shaft, refractory brick etc., redesign the grouting mouth of small furnace head position, then weigh
It newly builds small burner refractory brick and welds small protection board, on the one hand improve the sealing performance of coking furnace shaft burner, be allowed to not smolder,
It meets environmental requirements；On the other hand, the grouting mouth of redesign can be in the milk in daily production process, meet production need
It wants.
The method for maintaining that 7.63 meters of small burners of coke oven of the invention are smoldered is in husky steel, the small burner maintenance of 7.63 meters of coke ovens of Ma Gang
It is used in engineering project, ensure that the leakproofness at entire coke oven end position after construction, no longer smolder, effect is obvious, receives
The affirmative of relevant departments and unit.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
