The sealing device fireproofing material construction method among the technology sections of the annealing furnace has the advantages of being reasonable in construction step design, easy to operate and good in construction quality and working environment.
Description
Technical field
The present invention relates to a kind of method for constructing refractory materials, specifically, is the sealing device method for constructing refractory materials between a kind of annealing furnace process section of cold rolling industry.
Background technology
The annealing furnace of cold rolling industry is the common device of smelting industry, and annealing furnace is divided into a plurality of process sections according to the process requirements of producing product, and the manufacturing parameter of each process section is not identical, adopts sealing device to separate.Sealing device each side requires high, and linear dimension requires accurately.Because sealing device is simultaneously in two kinds of production environments, easily damage, need to often change.The refractory material of sealing device liner both at home and abroad conventional construction method all adopts sealing device shell to carry out the construction of online refractory material after installing again, and its construction technology is loaded down with trivial details, conventionally causes construction quality to be difficult to control, the result that construction operation environment is poor.
Therefore the sealing device method for constructing refractory materials between known annealing furnace process section exists above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is to propose a kind of construction quality good, and operating environment is good, does not affect the sealing device method for constructing refractory materials between the annealing furnace process section of annealing furnace refractory material total time of construction.
For achieving the above object, technical solution of the present invention is:
A sealing device method for constructing refractory materials between process section, is characterized in that comprising the following steps:
A, sealing device shell are inspected for acceptance
According to the shell drawing of sealing device, close inspection size; After acceptance(check), be placed on smooth construction site, and be fixed;
B, welding and processing anchoring piece
Refractory material construction drawing according to sealing device, has welded anchoring piece, 6mm ceramic fibre parcel for all anchoring pieces of furnace bottom, and the asphalt caulk of the anchoring piece brushing 1mm at other positions, and lay insulation material;
C, refractory material for working layer cast, comprise following steps:
(1) water the bottom of pouring seal device;
(2) water the two sides of pouring seal device;
(3) water sealed at both ends of pouring seal device;
D, refractory material maintenance
All, after refractory material casting, remove mould template; The natural drying maintenance of refractory material casting material transported installation site to after 48 hours;
E, sealing device integral installation
During sealing device integral installation, avoid concuss and shock, the dilatation joint after installing between filling and annealing furnace.
Sealing device method for constructing refractory materials between annealing furnace process section of the present invention can also be further achieved by the following technical measures.
Aforesaid method, in wherein said step c, during refractory material for working layer cast, installing template must not be out of shape, and dilatation joint is straight, stays to establish to meet design specification requirement, pours into a mould castable vibration compacting by the cast unit precedence of planning in advance.
Adopt after technique scheme, the sealing device method for constructing refractory materials between annealing furnace process section of the present invention has the following advantages:
1, construction procedure is reasonable in design, simple to operate;
2, construction quality is good, operating environment is good.
Accompanying drawing explanation
Fig. 1 is the sealing device of the embodiment of the present invention position view between A process section and B process section;
Fig. 2 is the sealing device structure of refractory schematic diagram of the embodiment of the present invention.
In figure: 1 sealing surface first half castable, 2 sealing surface anchoring pieces, 3 sealing surface Lower Half castables, 4 lower surface tapetum fibrosums, 5 bottom anchor parts, 6 bottom heat-insulation layers, 7 bottom pouring material.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Fig. 1 is the sealing device of the embodiment of the present invention position view between A process section and B process section.Silicon steel production line annealing furnace total length 355m, be divided into radiant tube bringing-up section, the first soaking zone, electric heater section, the second soaking zone, the first air cooling section, the 3rd soaking zone, the second air cooling section, fast cold section, air cooling section, have 9 process sections, 8 sealing devices need to be set.
Sealing device method for constructing refractory materials between annealing furnace process section of the present invention, is characterized in that comprising the following steps:
A, sealing device shell are inspected for acceptance
According to the shell drawing of sealing device, close inspection size; After acceptance(check), be placed on smooth construction site, and be fixed.
B, welding and processing anchoring piece
Refractory material construction drawing according to sealing device, has welded anchoring piece, 6mm ceramic fibre parcel for all anchoring pieces of furnace bottom, and the asphalt caulk of the anchoring piece brushing 1mm at other positions, and lay insulation material.
C, refractory material for working layer cast, comprise following steps:
(1) water the bottom of pouring seal device, described bottom is divided into 6 cast unit of left and right two row, first with the time, pours into a mould 4 cast unit of head and the tail of two rows, then pours into a mould unit with time cast two rows' 2 of centres;
(2) water the two sides of pouring seal device, from beneath toward 6 cast unit of upper two row, with within 6 days, completing cast;
(3) water sealed at both ends of pouring seal device, from beneath toward 6 cast unit of upper two row, with within 6 days, completing cast; When refractory material for working layer is poured into a mould, installing template must not be out of shape, and dilatation joint is straight, stay to establish to meet design specification requirement, by the cast unit precedence of planning in advance, pour into a mould castable vibration compacting, each step engineering time is 24 hours, and working lining pouring construction comes to 12 days.
D, refractory material maintenance
All, after refractory material casting, remove mould template; The natural drying maintenance of refractory material casting material transported installation site to after 48 hours.
E, sealing device integral installation
During sealing device integral installation, avoid concuss and shock, the dilatation joint after installing between filling and annealing furnace.
In the present embodiment because sealing device refractory material is off-line construction, and other positions of annealing furnace construct simultaneously, have saved a large amount of engineering times; Working space is independent, and construction operation environment is good, and quality control on construction is good, and particularly dilatation joint stays that to establish mass effect good.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
