Description
Technical field
The present invention relates to the fluidized roaster technology, specifically a kind of fluidized roaster ball collar furnace roof and manufacturing process thereof.
Background technology
At present, the large-scale fluidized roaster that China uses (comprising the technology that other countries and China in the world introduce) all adopts domes.The arch angular diameter can reach 10M-30M, and operating temperature is generally at 650 ℃-1200 ℃ in the stove, and furnace roof working lining tradition adopts various wedge shape refractory brick to build working lining top building heat-insulation brick by laying bricks or stones.Sizable cavity is left on insulating brick top, and cavity top covers the furnace roof box hat and wall stove box hat is fixed together, and is used to prevent that distortion of Side wall box hat and rain and snow from washing away furnace roof.In order to prevent that acid fume corrodes in the stove, generally also need outside box hat, to do anticorrosion insulating layer.Its shortcoming is: one, this technology belongs to a kind of layering absolute construction, reason because of technology, stove needs blowing out for several times every year, its temperature rises with tens times of speed to hundreds of times ℃/h during each blowing out, furnace roof is produced bigger thermal stress impact, this strength makes masonry area brick produce shift reciprocately along the thermal stress direction along furnace roof working lining masonry in the transmittance process of arch angle.Two, because the existence of masonry brickwork joint and the thermal deformation of brick setting itself make working lining refractory brick by pinch off, furnace roof is further changed, masonry is loosening, produce furnace roof and leak cigarette, a series of pernicious chain reactions of degradation make the stove long-time running under unsafe hidden danger under the intensity.Three, its equipment leaks the cigarette serious environment pollution in a large number because of furnace roof, and furnace roof seriously causes whole furnace roof to cave in because of falling brick, causes security incident.Four, because ovalizing deflection has taken place for postrun furnace roof and arch angle, it is very difficult to build refractory brick when making furnace roof change maintenance again by laying bricks or stones, and the brickwork joint after the replacing is more inhomogeneous, and the speed of vault damage is faster.
Summary of the invention
Purpose of the present invention, the deficiency that is intended to solve the problems of the technologies described above discloses a kind of fluidized roaster ball collar furnace roof and manufacturing process thereof, does not match to solve the coefficient of thermal expansion that existing top construction exists, and structural stratification causes the problem of furnace roof large tracts of land damage.
The present invention is the deficiency that addresses the above problem, the technical scheme that is adopted is: a kind of fluidized roaster ball collar furnace roof, comprise the rainproof box hat of furnace roof, the lightening casting material heat-insulation layer, heavy wear-resistant castable work lining, arch angle collar tie beam, its heavy wear-resistant castable work lining adopts high-strength low-cement refractory pouring material or steel fibre to strengthen castable refractory, heavy wear-resistant castable work lining is the supporting course of spherical furnace roof, high-strength low-cement refractory pouring material that it adopts or steel fibre strengthen castable refractory and have replaced reinforced concrete structure, adopted when constructing and divided ring because of it, the method of block construction, laterally be provided with a plurality of ears stainless steel anchoring pieces at internal layer for this reason, ears stainless steel anchoring piece divides ring with institute, the heavy wear-resistant castable work lining of piecemeal connects into an integral body, on the collar tie beam Side wall of arch angle, be provided with the clay light-weight brick and connect muscle, outside the Side wall of arch angle collar tie beam, be provided with the Side wall and strengthen channel-section steel, internal layer at arch angle collar tie beam has the stainless steel anchoring pieces of organizing more, and the stainless steel anchoring piece is with the clay light-weight brick, heavy wear-resistant castable work lining and stove Side wall are strengthened the channel-section steel structure that is connected in one.
The heavy wear-resistant castable work lining internal layer of ball collar furnace roof of the present invention is provided with many group ears stainless steel anchoring pieces, and its ears stainless steel anchoring piece will divide the material feeding of watering of ring, piecemeal to be connected to become an integral body the wear-resisting work lining of heavy.
Arch of the present invention angle collar tie beam adopts the unshape refractory castable, and has high gumbo light-weight brick and fibrofelt to do intensity coupling and flexible coupling between stove Side wall and arch angle collar tie beam, is provided with the skeleton that the stainless steel anchoring piece is formed in the collar tie beam of arch angle.
Lightening casting material heat-insulation layer of the present invention waters the material feeding cast by pearlite light and forms, and thickness is greater than the wear-resisting work lining of heavy.
Heavy wear-resistant castable work lining of the present invention strengthens castable refractory by high-strength low-cement refractory pouring material or steel fibre and forms, and has replaced the heat resisting steel reinforced concrete.
The wear-resisting work lining of heavy of the present invention also utilizes cast to cut off on heavy wear-resistant castable work lining and reserves dilatation joint or stealthy dilatation joint.
The manufacturing process of a kind of fluidized roaster ball collar furnace roof of the present invention comprises the following steps:
(1), determine the center of gravity and the symmetrical centre of stove, set the center of circle according to the center of gravity and the symmetrical centre of stove;
(2), establish the center of gravity of furnace roof and symmetrical centre point-blank;
(3), angle collar tie beam (5) is encircleed in cast earlier;
(4), back cast heavy wear-resistant castable work lining (4), stove by different-diameter when cast heavy wear-resistant castable work lining (4) is separated into some rings according to the center of circle with furnace roof, again ring is divided into plurality of small blocks, arc length≤1.2 meter, every bottom, by the fritter formwork that is divided into, and implement continuous pouring;
(5), the cast lightening casting material heat-insulation layer (3), thickness is greater than heavy wear-resistant castable work lining (4);
(6), the rainproof box hat of furnace roof (2) is installed;
(7), shaping finishes.
Lightening casting material of the present invention adopts pearlite light to water material feeding, and market is on sale.
The present invention also adopts heat-resisting reinforced concrete anchor ear arch angle collar tie beam, castable demoulding after 24 hours when being shaped.
Rainproof box hat of furnace roof of the present invention and pearlite light water the material feeding close proximity, do not stay the gap.
Rainproof box hat of furnace roof of the present invention and body of heater Side wall box hat are not established external thermal insulation, and it mainly is to prevent to rain the erosion furnace body.
Advantage of the present invention is:
1, solved the coefficient of thermal expansion that existing top construction exists and do not matched, structural stratification causes the problem of furnace roof large tracts of land damage.
2, heat-insulation layer need not be set outside box hat.
3, boiler roof sealing is good, the body of heater one integrated mass, and material seal is in conjunction with very close to each other.
