Firebrick of buy of industrial furnace everybody expands seam stay set, cannot reduce the compressive strength of fill wall, and should ensure outside gas cannot be entered arrive inside the chamber of a stove or furnace or system of the steam inside furnace is outward transgression. In the light of fill wall different the position expands seamed place, structure, beam overall should conceive a requirement by the design.
Fill wall and machine equipment, prefabricated components, laid when mattering with eyelet, should consider the change of the norms after expanding, the wall heats up state standards or expand in order to make clear fill interstitial.
Expand seam inside should maintain Jian clean and neat, do not need to have small thing such as urban rubbish. In order to is added fill expanding seam the asbestine rope inside, want to put in the ooze inside slop of rarer artesian well of fire prevention material first. Expand seamed beam overall is 20mm commonly, the asbestine rope that appropriate chooses straight 25mm is added fill.
1, boiler setting expands seamed fundamental means
Boiler setting expands seamed fundamental means has dentate and connect continuously form 2 kinds.
2, perpendicular to expand seam stay set pattern
(1) fill wall is perpendicular to expand dot of seamed place, bottom and some higher design level should press a design to conceive a regulation, put a line to make clear according to construction.
(2) expands once seamed place is clear, should press expand seam tectonic regulation (it is straight seaming Zuo repeatedly is dentate seam, the) such as beam overall, make clear the group step means of fill wall, begin check of brick extraction order to seam.
(3) is perpendicular to expand the way that the build by laying bricks or stones outside seaming grows to should choose plumb-line or place wooden appearance edition operates build by laying bricks or stones is built. Should expand seam for dentate when, appropriate pulls bisectrix to operate expand seamed flatness and beam overall; should expand seam when be direct form, the wooden appearance edition that appropriate chooses brae having a place operates expand bulgy parallelism and beam overall.
3, perpendicular to expand, seamed block
(1) is aimed at connect form vertical stroke continuously to expand seam, can get on suspension of asbestine rope upend at furnace frame or provisionality lever body, control asbestine string into when build by laying bricks or stones is built expand to seam and be squeezed close.
(2) is aimed at hand in fold expand seam, appropriate uses short asbestine rope, board wants before blocking up proper card is close.
(3) should expand seam inside when filling melt to be fireproof fiber felt, should press paragraph of build by laying bricks or stones to build expand the fill wall that seams both sides. Choose stick receive a dose felt of will fireproof fiber is sticky be stuck at fill wall at the same time, felt of will fireproof when build by laying bricks or stones builds across fill wall fiber is squeezed close.
(4) should expand seam inside inserts man-made board, chipboard or polystyrene board board when, should be put when build by laying bricks or stones builds fill wall and clip is held, inserts Bao Hou be sure to accord with expand seamed beam overall regulation.
4, expand seamed metallic finishing
(1) is in of fill wall expand seam inside when sealing an asbestine rope, of the wall in relying on the job inside furnace most outside an asbestine rope, should soak high pure black lead oar or brick of edge of slop of artesian well of fire prevention material seam a place of strategic importance to enter, asbestine rope should maintain upend with wall, cannot bulgy inside sunken.
(2) is in of fill wall expand seam inside when sealing the shape that block felt up or accumulation inserts, if seam inside the wall in filling the job inside melt and the chamber of a stove or furnace is not entire smooth, can choose tall to stick receive a dose or the mix up of polyester fibber short staple with grain alumina concrete and same inserts is well-balanced, with fill seam a knife to will expand seam with wall Gou Ping.
5, the level expands seam stay set
(1) expands when the level seam above when installing Xuan to metallic stuff holds bricky board in the palm, should expand with holding the specific design elevation of bricky board in the palm to operate the build by laying bricks or stones that seams below fill wall builds; to expand when the level seam on end constructs by strong point of special shaped brick when strong point, should expand by elevation general first seam indicate to go up in circumjacent machine equipment, furnace casing or burner framework graph, with operating the build by laying bricks or stones of below fill wall is built.
(2) build by laying bricks or stones builds whole process in, should examine at any time and place the norms that is apart from design elevation to control a route, the brick applies when needing public errand of negative pole dimension or adjust ash seams Bao Hou, facilitate make whole brick layer exceeds level.
(3) expands when what hold bricky board in the palm to fall seam when cannot conceiving norms in order to consider a design, producible treatment holds the brick of bricky board below in the palm. The Bao Hou of the brick after production is machined cannot the 2/3 under former brick Bao Hou.
(4) expands when the level seam on when the wall of the tectonic fill that it is a brick that carries strong point, should use design level concessional deviation will adjust specific design elevation, do not suit production to machine a brick.
6, the level expands those who seam seal a means
(1) expands when the level seam on when end constructs for strong point of special shaped brick, should accord with formulary provision to install a law to spread inserts with the shop outfit is whole smooth, subsequently build by laying bricks or stones builds strong point brick.
(2) expands when the level seam on carry strong point construction to be when holding bricky board in the palm, should choose seal a law to fill the administrative levels that fill melt close.
7, of arc wall expand seam
Be aimed at arc wall expand seam, use arc stuff normally stay among wall and plastic outer covering set clearance to replace expand seam, seaming inside add fill fill medicinal powder shape insulation material or slop of artesian well of fire prevention material, wait like pearlite pink, vermiculite pink. If plan institute shows 5 graphic representation. Expand seam the fill mother inside to expect squeezing ramming is spent as far as possible, well-balanced.
8, hearth expands seam
Be like steel of set of body of hearth build by laying bricks or stones when prefabricated components, stay between metallic stuff and fill wall set expand seam, make metallic stuff is being added lukewarm when should expand at will, seam inside make fill mother material with asbestine rubber slab.
When build by laying bricks or stones builds magnesia brick or hearth of magnesian chromic brick, every cross 3~4 piece brick to leave those who set this thick 2~3mm to expand seam, seaming inside fill put the chipboard with one thick 1mm.
9, vault expands seam
Stay in vault both sides normally set expand repeatedly continuously seam. Stay when setting, stand except what consider vault to extend outside, return what should consider upgrade of both sides boiler setting to expand. When the accident of vault exceeds 5m, except stay in both sides set expand outside seaming, still should press according to its accident paragraph, in vault in the south stays set expand seam. Arch expand seam apply one layer upon layer cover of the smooth layer that cut a brick.
10, suspension type roof expands seam
On suspension type roof, choose commonly getting close to the brick of both sides wall lists side and end end to stay set expand seam, seam inside add fill asbestine rope, if plan institute shows 7 graphic representation. After brick of arch of a sidewards the back stays set expand seam as same as side.
11, the line in pipeline expands seam
Expand inside pipeline those who seam stay set pattern. Sidewards expands seam ensure azimuth of accident of fill wall edge expands, the annulus among seams li of lining to ensure along straight azimuth expands.
12, heating furnace boiler setting expands seam stay set
(1) foundation sets. Heating furnace boiler setting should device of according to machine is technical the requirement air of documentation vents expand seam, error of its beam overall is negative pole 3mm, bounds should be rectified smooth. When there was not a demand on design conception, body of every meters chief build by laying bricks or stones expands seam all be worth mark value, it is 5~6mm to wall of clay brick fill, wall of fill of tall aluminous firebrick is 6~7mm. Buy of boiler setting everybody expands those who seam stay set, not allow to make the compressive strength that reduces fill wall already, should ensure again the tight of boiler setting.
(2) expands seam stay set. Expand seam inside what seal the asbestine rope that block up to answer beforehand is put in slop of artesian well of fire prevention material to soak, expand to make asbestine rope is bespread inseparably seam, the straight of asbestine rope should expand more than a bit seamed space, below major state, expand seamed beam overall is 20mm, the straight that chooses asbestine rope is 25mm. Expand seamed Xiang Huo face most outside an asbestine rope should be made the same score together with firebrick boiler setting, cannot bulgy inside sunken.
The partition wall inside furnace or She Yan wall are extended it is advisable to enter firebrick layer 90~95mm. When boiler setting is longer, can be in in the middle of add set expand seam, if plan institute shows 10 graphic representation. Of boiler setting vault expand seam except outside filling asbestine rope, seam show one part to want to use the one layer upon layer cover that make the same score a brick.
(Structure of the metal in 3) boiler setting expands seam stay set. Expand to ensure what heating furnace encounters heat hind is optional, its cross wall canal, header, drum to wait annular outside, should voluminous cast in wall of; of rope of asbestine of straight 10~20mm all round should add fill the asbestine rubber slab with large 10~15mm of the drum in; wall expand seam, it is down drum the build by laying bricks or stones on the circle builds annular cup one hand in the other before the chest, in the asbestine string that fills straight to be 25mm is bought among drum and arch.
