The build by laying bricks or stones of firebrick builds a requirement to have the following demand normally:
1, arch and vault must be built to central semmetry build by laying bricks or stones at the same time from foot of two side arch, when build by laying bricks or stones is built, forbidden should call the Suo Zhuanjun of; of convert of differ in roll end diameter of arch brick person cup one hand in the other before the chest from flank inside, if the brick is locked up in last, cannot lay a person from flank when, but 2 bricks undertake the 1 ～ that will lock up buccal a side first treatment, make dimension of the fluctuation that lock up a mouth equal, the lock brick that will suit with photograph of the dimension that lock up a mouth next from above lay a person, and its two side tighten; to demolish what arch embryo is locking up a brick to hit foot of close, arch to be in entirely to dig channel build by laying bricks or stones to build with armor plate a place of strategic importance end and after framework pulls the nut of the hook to screw finally, Fangke undertakes.
2, build imprecise brick to seam to build by laying bricks or stones, should infiltrate a place of strategic importance of thin stencil steel is tightened, answer to the furnace kiln that can turn especially every rotational 1/4 circle undertakes checking, adopt afore-mentioned measure to remedy.
3, stay set expand seamed position, should keep away from the hole in framework of place getting power, body of heater and body of build by laying bricks or stones, expand outerly inside body of build by laying bricks or stones seam do not answer interpenetrate, fluctuation layer should stagger each other.
4, by the side of the length that is not stratosphere of bottom of arc hearth, passageway, should as perpendicular as the direction of going from place to place of charging, metal, broken bits or gas or into one included angle.
5, circular boiler setting should be built by central line build by laying bricks or stones, when the requirement that accords with the form inside furnace when the error of diameter of central line sum of errors of furnace casing, can furnace casing is built to guide the face has step.
6, circular boiler setting must not have three-layer or 3 annulus are seamed again, layer and two photograph neighbour play on of two annulus seam again must not nod in same ground
The straight form bricklaying of the firebrick lining of hot project facilities such as industrial furnace kiln (wall, bottom) build firebrick with radiation form build by laying bricks or stones (the annular build by laying bricks or stones of the furnace that be like Zuo , converter and rotary kiln builds firebrick, kiln of furnace of one Yi industry is vaulted build by laying bricks or stones builds firebrick, the ball top build by laying bricks or stones of hot-blast stove and electric stove builds firebrick to wait) in, often use straight form firebrick, wedge firebrick, arch foot firebrick and ball top firebrick. The norms of these firebrick reachs size, cannot choose at will.
What meaning does the brick of firebrick seam? Need to use material felt between brick and brick namely, or fill, it is the high temperature that uses same capable person to pledge usually fireproof mud, if be dry build by laying bricks or stones, the powdery material that uses as identical as firebrick component comes fill brick is seamed.
The brick of firebrick seams the introduction
When firebrick build by laying bricks or stones is built, can have between brick and brick or big or little gap exists, high temperature blaze can pass aperture to wear away to heating up labor facilities to cause, erode, happen to avoid this kind of issue so, the fireproof mud of same raw material or powder are used in the meeting when firebrick build by laying bricks or stones is built, use fill brick to seam, those who hold back high temperature blaze erode reach erode.
The brick of firebrick seams ply
The brick of firebrick of body of industrial furnace build by laying bricks or stones seams ply to should press place of body of heater and manufacturing condition by set juice to decide. The basis produces practice and construction careful degree, the brick of body firebrick seams build by laying bricks or stones of general industry furnace to ply presses furnace place and differ somewhat. What should accord with regulation laying a plan commonly is numeric. Seam ply to have to the brick of firebrick special the furnace that an ancient unit of weight asks or place, by set juice to decide. The central line of industrial furnace and elevation control line should press the regulation that set juice to measure this to decide via professional. Firebrick is built in build by laying bricks or stones before, answer to reach the size putting a line of body of build by laying bricks or stones of dimension school nucleus according to the norms of firebrick.
The build by laying bricks or stones of firebrick builds method and brick to seam a requirement
1. Firebrick build by laying bricks or stones builds a method simpler, with respect to its methodological cent does build by laying bricks or stones and wet build by laying bricks or stones two kinds. Dry build by laying bricks or stones need not slop,
2. Category of body of firebrick build by laying bricks or stones is the requirement of careful to construction degree, basically point to the size that the brick seams. Cent of category of body of build by laying bricks or stones is special kind, labour kind, Ⅱ kind, Ⅲ kind, Ⅳ kind 4 kinds. There is a demand in graph of construction of general kiln furnace, special the brick of its firebrick seams body of kind of build by laying bricks or stones to not be more than 0.5 millimeter, be versed in body is not more than kind of build by laying bricks or stones 1 millimeter, Ⅱ kind body of build by laying bricks or stones is not more than 2 millimeter, Ⅲ kind body of build by laying bricks or stones is not more than 3 millimeter,
When if blueprint does not have the category of body of specific requirement build by laying bricks or stones or brick,seaming size, need fibrous root seizes the property of furnace kiln, the temperature ability of each place is affirmatory. If be firebrick, adiabatic firebrick and red brick when, can consult following regulation (unit millimeter) :

Firebrick build by laying bricks or stones builds a note:
1. firebrick asks build by laying bricks or stones seams full oar, the brick seams width to should accord with blueprint to design a requirement.
After every firebrick puts 2. , want to use wooden hammer or rubber hammer to beat, so that squeeze an over fireclay, should make sure the brick is seamed stick completely with housing close, surface contact should be between firebrick and union is firm. When beating firebrick, should prevent to be beaten unsuitedly or extruding injures firebrick or injury begins caky fireclay.
Raze answers before the fireclay unfinished that 3. seams in the brick is completely sclerotic redundant fireclay, when if have some of place,still needing fill fireclay, apply new fireclay of fact of drawknife a place of strategic importance,
4. ash is seamed want horizontal smooth upend, dambered surface is calm, contact is close, should make sure body of build by laying bricks or stones and each equipment place are denotive measure is consistent.
5. straight wall uses a fault to seam build by laying bricks or stones to build, vault and kiln should be used in circumferential clitellum direction direct seam build by laying bricks or stones to build. Build by laying bricks or stones builds comfortable stress to beg a brick to seam flat dambered surface smooth. ensure quality.
6. holds bricky board and flange in the palm dish wait for metallic parts of an apparatus to cannot be contacted directly with firebrick, should besmear in parts of an apparatus fill fireclay, hold in the palm should stay below bricky board make an appointment with 10mm to expand seam. Expand fireproof fiber felt can fill in in seaming, hold bricky board in the palm in order to protect. Flange and metallic parts of an apparatus can use fireclay to execute close, avoid metallic parts of an apparatus and contact of high temperature gas.
7. arrives from construction in the process of devoted production, should prevent system of build by laying bricks or stones be affected with damp be affected with damp and suffer aspic, also should prevent to appear prematurely exorbitant temperature, the intensity that makes fireproof mud short of due.
