Description
Technical field
Integral casting construction process when the present invention relates to coke dry quenching boiler and building belongs to the coking production equipment technical field.
Background technology
Dry coke quenching is to utilize a kind of method of rare gas element to red burnt cooling, and dry coke quenching is to carry out in coke dry quenching boiler (being generally called the dried stove that puts out).Because frequent thermal shocking in the dry coke quenching process, make the dried interior masonry of stove that puts out very easily damage, generally adopt to lay bricks in the overhaul construction process at present and inlay mending option, the conventional scheme of laying bricks quantities is big, the masonry globality is poor, the time-consuming material that takes, cost height, work-ing life is short, also can repeat same damage phenomenon in the some months.
CN101250414 discloses a kind of restoring method for chute of dry quenching furnace, is used to solve the problem that chute of dry quenching furnace is fragile, repair difficulty.The anti-material of used repairing is the mullite silicon carbide gravity flow pouring material, the gravity flow pouring material weight proportion is: aggregate 6～7, matrix 3～4, stainless steel heat-resistant fiber 0.1～0.3, wherein aggregate is partly by following weight unit proportioning: fused corundom 45～60, high-purity low iron mullite synthesizing 10～20, superfine silicon carbide 8～15, matrix part unit by weight is made up of following raw material: high purity silica powder 4～8, silicon carbide ultrafine powder 2～6, rafifinal hydrochlorate 3～5, active alpha-Al
2O
36～10.The refractory materials of apolegamy has remedied the defective that the common medium temperature intensity of anti-the material descends, on constructional method, adopt utilize heat-resisting reinforcing bar do stiffening web, to residual lining surface engaged structure treatment, adopt three on mould around methods such as pillar stiffeners, the repairing lining that makes cast with residual lining firm being meshing with each other be in the same place, further improve the structural stability of integral body.
CN101298565 discloses dry quenching boiler entrance area pouring process, this top, zone is that arc vault construction bottom is a square structure, adopt and the same the building by laying bricks or stones of the used brick of disposable dust remover vault by the disposable dust remover vault, the brick type is 140 tons of dry coke quenching special bricks, brick number is GAM2807, expansion joint zone GN53-Y108a, GN53-S110a builds by laying bricks or stones, build by laying bricks or stones with the GAM2807 brick by boiler side, need 8 rows altogether, the both sides side wall is built by laying bricks or stones with the standard clay brick, lay bricks with boiler area concatenate rule position, irregular area is handled with heat insulating casting material.This invention has solved the mould material difficult problem that comes off, guaranteed should the zone insulation, guaranteed normally carrying out of ash discharge operation, help whole dried steady running of putting out stove.
Above patent document all only relates to the dried stove part section reparation of putting out, and how not to destroy dried putting out under the stove original structure situation, puts out whole reparation of stove and does not appear in the newspapers as yet so far dried.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of integral casting construction process of dry quenching furnace.
Technical solution of the present invention is as follows:
A kind of dried stove monolithic casting construction method that puts out comprises the cast of putting out stove cooling section and the positive outside of chute bracket, boiler inlet both walls, bottom and the two fork chutes of disposable dust remover to dried, and step is as follows:
(1) for the dried stove cooling section that puts out, earlier clean body of wall with pressurized air, clean with clean-out system again, smear one deck high-temperature interface binding agent then, the forked type anchoring piece is installed, intert anchor slot at body of wall, formwork, it is integrated poured to adopt gravity flow pouring material to carry out, and pours into a mould cooling section at every turn and highly is 1-1.2 rice along the furnace wall annular, solidify after one day form removal and continue to top-pour along the furnace wall, one-piece casting thickness is 100-125mm.
(2) for the dried positive outside of stove chute bracket of putting out, earlier the coke powder in residual lining surface and the brickwork joint is removed, cleaned with clean-out system again, to chute bracket front formwork, flush with the top key brick, the open top perfusion gravity flow pouring material from formwork solidifies form removal after 12 hours.
(3) boiler inlet both walls and bottom are taked the formwork gravity flow pouring, along the vertical molding of boiler inlet both sides metope, gravity flow pouring material cast thickness is 100-125mm, and boiler bottom is directly gone up the self-flowing material cast, cast thickness 100-125mm.
The boiler vault is carried out spray treatment: at first remove the original damaged refractory materials of vault, on anchoring piece, brush pitch, sprayable refractory again, spray material layer thickness 18-20cm.
(4) adopt gravity flow pouring material to carry out the formwork gravity flow for the two fork chutes of disposable dust remover and build, and adopt the stainless steel anchoring piece.
After all cast finishes, the dried stove that puts out was carried out storing time 65-84 hour, temperature is no more than 600 ℃.
Preferably, when the cooling section described in the step (1) is installed the forked type anchoring piece,, treating on the benefit face stiffening web to be installed, and treating the benefit face and carry out the occlusion structure processing treatment, forming occlusion structure for improving the one-piece construction stability of repair layer and primary structure.
Clean-out system described in the above-mentioned steps (1), high-temperature interface binding agent all adopt state of the art, but market is bought.
The refractory materials spray material can adopt state of the art in the above-mentioned steps (3), but market is bought.The present invention preferably adopts the P130 refractory materials, and Beijing Ruipu Tongchuang Technology Development Co., Ltd. produces and sells.
Gravity flow pouring material described in the above steps belongs to repair uses material, can select currently available products for use, buys or press the known technology preparation by market, as the disclosed mullite silicon carbide gravity flow pouring material of CN101250414A.
Gravity flow pouring material described in the above steps, the preferred heat resistant and wear resistant SFM-2 of the present invention mould material, Beijing Ruipu Tongchuang Technology Development Co., Ltd. produces and sells, and SFM-2 mould material performance sees the following form.
During concrete the construction,, mould is designed according to the dried on-the-spot actual mapping size of stove, the deformed damaged situation put out.
Excellent results of the present invention is as follows:
The present invention is not destroying dried putting out under the stove original structure situation, take all factors into consideration the dried project organization that puts out stove chute bracket and cooling section, damage factors such as phenomenon, the source of damage, thoroughly solve the existing big problem of quantities in the mending option of inlaying of laying bricks, make the dried stove masonry good integrity of putting out, material-saving saves time, cost is low, the dried stove long service life of putting out in integrated poured repairing back.
