Cotton fiber ceiling brick blocks (ceramic fiber module) Description: Various brick ceiling fiber cotton block, with the corresponding material ceramic fiber blanket acupuncture, according to the fiber component structure, size, processed on dedicated machines. In the process, both to maintain a certain amount of compression ratio, in order to ensure that the ceramic fiber module wall lining building has been completed, the ceramic fiber module in the expansion in different directions, so that between each other extruded ceramic fiber module of a seamless, integral, ceramic fibers Modules can through various forms of anchors directly fixed on the industrial furnace furnace shell plate anchor nail. Features: (1) in various forms of anchors on the back of the folding module makes installation modules can fold out type arrangement using soldiers can be applied parquet-style arrangement; (2) folded blanket tied after the lifting will squeezing each other in different directions, no gaps; (3) Flexible fiber blanket can withstand mechanical force; elastic (4) fiber blanket deformation can make the furnace shell, so that no gaps between the component; (5) Because of its light weight, as little endothermic insulation materials; (6) the low thermal conductivity to bring high energy savings; (7) has the ability to resist any thermal shock; (8) lining the body without drying and curing, it can be installed immediately after put into use; (9) away from the hot surface anchoring system components, making the metal anchors at a relatively low temperature. A detailed description, a construction preparation, compulsory mixer or a mortar mixer. 2, welding one or two units. 3, the plastic film. 4, plus fill joints, plastic corrugated board, wood strips, fiber blankets. 5, a small scale. 6, a volume of 10 to 40 liters of a plurality of buckets. 7, a number of the trowel. 8, tamping tool. 9, in line with the size and number of drawings, anchoring nails from the corresponding material. 10, handsaw, scissors, iron milling and other sporadic tools. 11, raw material preparation. Castable refractory fiber (dry material) have been prepared in good production plant, with woven bag with plastic lining, a small bag and another bag individually packaged composite hardener. Before the construction of the material transported to the site, classified storage, safekeeping, to prevent bags or damaged, damp and rain. 12, remove slag furnace shell inside the steel surface, rust, loose mill scale and oil. 13. Construction ambient temperature should be ≥10 ℃ (ideal ambient temperature of ≥20 ℃), measures should be rain rainy season, winter construction to take precautionary measures. Second, anchoring nails welded one, anchoring nails four weeks should be fully welded, no bite of meat, welding firm should not be tainted welding and Weld. 2, anchoring nails vertical deviation should ≤5mm, height deviation of ± 2mm, pitch deviation of ± 5mm. Anchor bolt square layout. Anchor bolt spacing: furnace wall is 250-300mm, the roof is 200-250mm, shaped structure parts for 150-200mm. 4 different operating temperatures anchoring nails choice of materials listed in the table working temperature (℃) selection of materials ≤550 550-1000 1Cr18Ni9Ti 1000-1250 Cr25Ni20Si2 1250-1400 carbon steel and heat-resistant ceramic composite anchoring device ※ castable refractory fiber lining The anchoring nails completely covered, the actual temperature of the hot end of the anchor nail on the table listed below the operating temperature. 5, in the form of the structure is shown in anchoring anchoring nails to nail a nail anchor 4. 6, anchoring nails two points short nails and spikes, white layout. Castable refractory fiber lining after construction will be anchoring nails completely covered. Anchoring nails in the lining of the arrangement and thickness of the cover as shown below. Third, castable refractory fiber kneading 1, the preparation of a good dry material added to the mixer, start the motor during operation in a blender slowly added to the composite hardener, dry mixing 0.5-1 minutes. 2, dry mix well, add a predetermined amount of water, stir 2-3 minutes to use the material. Different density of castable refractory fiber add water amount listed in the following table. To add water metering, control and accurate. Castable refractory fiber density and add water amount 0.65g / cm3 (650kg / m3) dry material weight 100-120% 0.70g / cm3 (700kg / m3) dry material weight 80-90% 0.80g / cm3 (800kg / m3 ) dry material weight 65-75% 1.0g / cm3 (1000kg / m3) dry material weight 55-60% 1.2g / cm3 (1200kg / m3) 55-60% by weight of the dry material 3, the mix should be 20 within minutes run out, the interval is too long to prevent the occurrence of induration material impact of the project quality. Fourth, the construction method of construction methods are casting three projection method and smear method. 1, cast construction methods. (1) hierarchical sub-parts casting, can cross the job. Stratified casting furnace wall, each height 700-1000mm. Segmented roof construction, expansion joints between two roof should be completed once the casting. (2) according to the size of branch design requirements set a good template, template medial layer of plastic film, pour the mix into the template, the fabric should be uniform, not use vibrators vibrator. (3) the capacity of castable ≤0.8g / cm3, and after pouring layered compacted with a trowel, capacity castable ≥1.0g / cm3, and after pouring pressed tamping with ┵ tamping tool. (3) conservation and Chaimo: ambient temperature ≥20 ℃, nature conservation can form removal after four hours, the ambient temperature ≤20 ℃, nature conservation Chaimo 5-7 hours, as occurred after the local angular Chaimo damage, can be repair. Roof removal time should be extended as appropriate. 2, cast construction method (1) the mix artificial projection method, layers of projected work surface, when projected thickness of the design size, compaction with the trowel, trowel. (2) the furnace wall and vertical pipes lining the bottom-up hierarchical construction, each height 700-1000mm, Nature Conservation 3-4 hours after each construction constructability second layer. (3) This method does not apply to the roof surface lining construction. 3. Apply construction method (1) Apply the mix with artificial methods, direct smear job surface. (2) bottom-up hierarchical continuous furnace wall painting, each height 700-1000mm, every smear thickness 50-100mm, continuous smear several times until the thickness reaches the required size, with a trowel trowel compaction , each 3-4 hours after construction Nature Conservancy, constructability second layer. (3) roof piecewise continuous smear, for a period of between two joints, each smear smear thickness 30-50mm continuously until the thickness reaches the required size, with a trowel trowel compaction. (4) large diameter horizontal pipe insulation lining, should adopt the first segment of construction lining, then set up the connection method, pipeline construction segment, the pipe will be placed horizontally, first smear under semicircle lining, nature conservation 4- After 8 hours, the pipe flip angle of 180 °. Apply another semicircle lining, pipe connections do after seaming. 4, leaving in expansion joints (1) as the surface castable lining (Face) when the materials used, the need to stay reasonable expansion joints. (2) vertical joints from the corner of the wall at the beginning of one meter, leaving in a 1.5-2 m intervals, joints width of 10-15mm. (3) horizontal joints about every 1.5-2 m height leaving in an expansion joint width 10-15mm. (4) Press the furnace roof length direction, every 1.5-2 m leaving in a 10-15mm wide joints. (5) ≥2 m diameter pipe lining layer, vertical joints by leaving in an arc length of about 2m intervals, ring joints, leaving in a height of about 2m intervals, joints width of 10-15mm.
