Ki jan yo bati brik yo refractory nan chodyè a?

1. Etap konstriksyon yo te pote soti nan akò ak prensip la nan anba nan tèt ak soti nan andedan deyò. Pati ki pi ba nan tanbou anwo a ak plak flanm dife entèval tib konveksyon an yo vide soti anwo jouk anba.

2. Miray founo a gen gwo kondisyon sere lè, ak plenite nan jwenti sann: brik wouj yo pa mwens pase 85%; brik REFRACTORY yo pa mwens pase 90%. Metòd la peze yo itilize pou masonry brik wouj, epi yo itilize metòd grate pou masonry brik refractory.

3. Masonry nan fon gwo founo dife:

(1) Anvan yo mete anba a founo, yo ta dwe nivelman fondasyon an, epi yo ta dwe bati miray ki antoure yo dwat ki an kontak ak anba gwo founo dife a an premye, ak wotè a ta dwe apeprè pi wo pase sifas anba gwo founo dife a. Lè sa a, make liy orizontal anba founo a (nan ka masonry milti-kouch, ansanm ak kantite kouch) sou miray dwat la anvan yo ka bati anba founo a.

(2) Lè fon fou a konpoze de plizyè kouch brik, masonry a ta dwe fèt kouch pa kouch, ak kouch anwo ak pi ba yo ak menm kouch brik la dekole, ak bò long brik ki pi sifas yo. pèpandikilè ak direksyon koule nan salop oswa gaz.

(3) Nan zòn ki wo tanperati ak fon founo ki souvan bezwen ekzamine, yo ta dwe kite yon espas ekspansyon nan kontak ant anba fou a ak miray dwat la, ak kòd amyant oswa tablo amyant pad yo ta dwe entegre nan espas sa a.

4. Masonry nan bokit sann (ki gen ladan mi enkline):

(1) Anvan bati bokit sann lan, premye chèche konnen liy santral orizontal la dapre desen yo, epi sèvi ak liy sant orizontal la pou jwenn liy santral la longitudinal nan chak bokit sann ak bor yo deyò nan mi yo devan ak dèyè dwat nan salop la epè. bokit, ak Lè sa a, baze elevasyon an sou tou de bout. Pop moute liy sant vètikal la nan pati anba a nan Hopper sann dife a, epi mete gwosè a nan pati anba a nan Hopper a sann. Apre eklate liy oksilyè vètikal la, sèvi ak modèl triyang pwodwi a (te fè dapre pant miray enklinezon an nan desen an), epi trase liy bò miray enklinezon an sou tou de bout kanpe fondasyon an. Sifas. Sèvi ak menm materyèl la nan konkrè refraktèr pou fè revers triyangilè a nan pati anba a nan miray la enkline (jan yo montre nan Figi 1) ak nivo miray la dwat. Dezavantaj triyangilè nan junction nan miray vètikal, orizontal ak enkline yo dwe vide tou ak beton refractory nan menm materyèl la. Kontinye nan masonry mi an pant.

(2) When building the ash bucket, first build the horizontal and then the vertical; when the inclined wall and the straight wall are formed, build the straight wall first and then the inclined wall.

(3) Lè gen sipò fondasyon sou do a nan miray enklinezon an, mòtye a sou sifas kontak ant brik yo ak fondasyon an ta dwe plen; Yon fwa sann, sann yo dwe konpakte.

5. Masonry of straight walls:

(1) The straight walls around the boiler are composed of refractory bricks, thermal insulation bricks (or thermal insulation layer), and red bricks. The order of masonry construction is to build refractory bricks first, then thermal insulation bricks (or paste insulation boards or felt), and finally red bricks. For example, when the hot joint between the refractory brick and the red brick is filled, the filler should be filled every 3 to 4 layers of the red brick, and the filling should be dense.

(2) When building a straight wall, it must be placed at the corner of the furnace wall. The two ends of the straight section must be yarded with 2~3 layers of heads, and the horizontal line must be held. Build the mortar joints, leave the expansion joints in place, hang the vertical expansion joints asbestos ropes, and paste the asbestos panels on the steel frame facade before proceeding to masonry.

(3) Metòd masonry nan masonry miray dwat se: 1/2 miray epè brik adopte jwenti dekale ak 1/2 masonry longè brik; 1 brik ak pi wo miray epè adopte yon tèt ak yon metòd masonry pakè dwat oswa fèmen. Kouch anwo oswa anba brik 1 brik ak 1 masonry epè brik dwe masonry anwo oswa bò kote.

(4) Lè tou de bò miray founo a ap travay sifas (eksepte pou mi ki gen yon epesè 1 brik oswa mwens), tou de bò yo dwe mete an menm tan.

(5) The water-cooled wall header and the pipe side and the sliding support of the pipe side passing through the masonry shall not be fixed, and the special-shaped brick at the pull hook of the water-cooled wall shall not jam the ear plate of the water-cooled wall.

(6) Lè brik REFRACTORY yo ak brik wouj yo rasanble, lè brik REFRACTORY yo bati ak 6 a 8 kouch wotè brik, chak 1 a 1.5m sou direksyon orizontal la, 115mm long brik lonje dwe pwolonje nan miray deyò a nan. brik wouj yo. Brik tansyon yo ta dwe dekonekte sou menm kouch la, epi kouch anwo ak pi ba yo ta dwe repati.

(7) Lè bati miray deyò a nan brik wouj, twou vantilasyon yo dwe bay, ak distribisyon an nan espas rezève yo ta dwe menm. Youn ka rezève nan apeprè 2m2 epi antere l ak DN15 ~ 20 tiyo fè nwa (nan ka sikonstans inevitab, sèvi ak rezève metòd twou 60 × 120mm). Chodyèr ak griyaj kòmanse mete kanpe lè griyaj la kole; chodyèr san griyaj kòmanse yo dwe mete kanpe nan yon elevasyon nan apeprè 1m, ak pwen ki pi wo a nan kouti izolasyon an dwe tou mete kanpe, ak fou a dwe bloke ak materyèl tanperati ki reziste imedyatman apre dife pou chofe fou a fini.

6. Masonry nan ouvèti miray founo, twou enspeksyon, elatriye adopte metòd masonry ke brik yo REFRACTORY nan miray enteryè a antre nan brik wouj yo nan miray deyò a (gade Figi 2). Lè konsepsyon kouvèti anwo a nan ouvèti a (twou) obligatwa, masonry a dwe bati selon kondisyon konsepsyon yo, epi lè konsepsyon an pa obligatwa, masonry a dwe bati nan fason sa a:

(1) The width of the hole (hole) in the wall is less than or equal to 450mm. If the span is not large, the solid platform method can be used to replace the small arch with a flat brick layer. The masonry method is shown in Figure 3. Each layer shall protrude ≤6mm from both sides into the opening until the opening is covered. The protruding length of each layer and the same layer shall be the same.

(2) Lajè ouvèti a (twou) nan miray la ≤250mm ka kouvri pa brik pwosesis. Metòd masonry yo montre nan Figi 4.

(3) Lajè twou nan miray la> 450mm lajè dwe kouvri pa masonry vout-wotasyon.

7. Masonry nan vout ak vout:

(1) Reyon mwazi kawotchou a ak gwosè pwodiksyon radian ki nesesè pou masonry vout ak vout dwe satisfè kondisyon konsepsyon yo. Espas mwazi kawotchou a se mwens pase span aktyèl la pa 20 ~ 30mm, sifas la se plat ak lis, epi li gen materyèl chaj-pote ak chaj konstriksyon san kapasite deformation.

(2) Anvan ark masonry, masonry dèyè ark-pye brik yo dwe ranpli, epi masonry a ka sèlman bati apre yo fin pase enspeksyon an. Apre brik ark-pye yo, li pa pèmèt yo bati brik refractory izolasyon chalè oswa brik brik alg latè.

(3) Anvan yo bati tèt la vout, gwo bout bwa zòtèy vout la ak kolòn ankadreman an dwe fèmen ansanm. Anvan mete vout la nan ankadreman an reglabl, ankadreman an ak baton mare yo dwe ajiste ak fiks, epi yo te pase enspeksyon an.

(4) Anvan masonry vout la ak vout, premye enstale mwazi kawotchou a, tcheke elevasyon an ak pozisyon, ranje li byen fèm, ak Lè sa a, pote soti nan pre-masonry. Objektif pre-masonry se sitou ajiste jwenti mòtye yo ak rasanble brik vout yo. Modèl pou satisfè kondisyon yo nan bon jan kalite masonry vout ak jwenti repati. Apre aranjman asanble ark brik la satisfè kondisyon yo, figi brik yo nimewote dapre lòd masonry yo epi retire yo, jan yo montre nan Figi 5. Masonry a dwe simetrik bati soti nan pye vout la nan sant la an menm tan. Li se entèdi entèdi tèt anba masonry la.

(5) Sòf si gen règleman espesyal, ark yo ak vout yo dwe mete nan jwenti dekale, epi yo ka mete ark ak vout ki gen diferan trave nan bag. Nan ka masonry jwenti repati, lè longè jwenti longitudinal la pi long pase 1 mèt, masonry a dwe trase ak yon liy.

(6) Brik fèmen yo dwe enstale nan masonry a nan vout la ak tèt vout. Pwofondè brik fèmen bati-an se 2/3 ~ 3/4 nan epesè vout la ak tèt vout. Jan yo montre nan Figi 6, pwofondè fèmen nan menm vout la dwe menm. , Lè fèmen nan, li ta dwe soti nan fèmen nan pi sere nan looser la. Nan miray la, plizyè ark adjasan ak brik fèmen nan do kay la vout dwe kondwi nan an menm tan an pou anpeche deformation nan ark adjasan yo.

(7) Brik fèmen yo distribye egalman ak simetrik. Kondwi nan yon sèl brik fèmen pou span <3m, epi kondwi 3 brik fèmen pou span> 3m. Ou ka sèvi ak yon mato pou kondwi nan lè li fèmen, men li dwe rembourré ak yon tablo an bwa.

(8) Li pa pèmèt yo sèvi ak brik ki gen yon epesè ki gen plis pase 1/3 oswa koupe bò long la fè gwo sifas la nan yon fòm bon rapò sere kòm yon brik fèmen.

(9) For the processed bricks that are leveled on the upper part of the arch and the vault, the high temperature area or the surface of the external wall can be leveled by brick processing, and the low temperature area can be leveled by the same material of refractory concrete.

8. Masonry tèt anba:

(1) Two arc-shaped boards inside and outside are made when turning upside-down masonry. The inner arc plate is made according to the radius of the rotation; the outer arc plate is made with the inner radius plus the thickness of the rotating brick.

(2) When building upside-down rotation, the bottom center line of the rotation is based on the arc-shaped slab, and the lower part is built. Generally, the length of the brick can meet 5~7 rotating bricks, then you can start to build upside down. Rotate, and then symmetrically build upside down from the center of the bottom of the upside down to both sides. Don’t hit too hard when starting to build to avoid shifting or loosening. After 5~7 bricks are built in the lower part of the inverted screw, the inner arc-shaped board is fixed on the surface of the rotating brick, and the bricks are symmetrically laid on both sides in the order of rotating the bricks and then processing the bricks. The masonry sequence is shown in Figure 7.

(3) Lè w vire nan 1/2 sèk, 1/2 anwo a adopte masonry vout ak vout. Lè bloke brik yo, vire brik yo alantou 1/2 nan wotè vektè anwo a epi fèmen brik yo apre masonry a fini, jan yo montre nan Figi 8.

9. Masonry nan pandye brik ak demolisyon nan mi flanm dife:

(1) Pann brik ak retire mi flanm dife swiv prensip la nan bati soti nan ba rive segondè, soti nan mitan an nan tou de bò.

(2). Lè brik yo bezwen trete pou konstriksyon brik pandye ak mi ki retire flanm dife, clearance nan twou yo pandye nan brik yo pandye pa dwe pi gran pase 5mm, ak epesè nan mi yo ki retire flanm dife pa dwe mwens pase 90. %. Pa dwe gen okenn fant nan pati prensipal yo ki bay fòs nan brik pandye yo.

(3) Pou brik ki gen fòm espesyal ak twou boulon fikse, premye ranje sèk pa kouch pou mete esè, epi apre yo fin make pozisyon twou boulon yo sou tiyo a, boulon fixation yo ka soude. Nwa yo pa ta dwe sere boulon twò sere pandan masonry pou fè pou evite domaje brik REFRACTORY yo, epi twou boulon yo ta dwe ranpli ak konkrè REFRACTORY.

10. Yo rete jwenti ekspansyon miray founo a:

(1) Kote ak fòm jwenti ekspansyon yo sou miray founo a an akò ak kondisyon konsepsyon yo. Lajè a pa pèmèt yo dwe pi piti pase kondisyon yo konsepsyon, ak objè difisil tankou brik kase yo pa gen dwa tonbe nan jwenti yo. Anbalaj la nan jwenti ekspansyon an byen chaje selon kondisyon konsepsyon yo. Lè yo itilize kòd amyant, premye a nan sifas flanm dife a dwe tranpe nan labou réfractaires.

(2) Water wall pipes, downcomers, headers, sewage pipes, drums, temperature measuring holes (tubes) and beams, etc., through the wall, leave expansion joints at the contact wall and the vertical and horizontal connections of the refractory brick furnace wall. It is better to wind with asbestos rope.

(3) Metòd pou kite jwenti ekspansyon miray founo a:

①. The method of retaining expansion joints at the corners is shown in Figure 9(a): the method of leaving the junction of 1/2 brick and 1 brick; Figure 9(b): the method of leaving the junction of 1 brick and 1 brick.

②. The method of setting expansion joints at the junction of the two ends of the demolition wall and the furnace wall is shown in Figure 10.

③. Metòd vètikal ekspansyon jwenti rete nan mitan miray founo a montre nan Figi 11.

④. The method of setting expansion joints at the junction of the furnace roof and the two ends of the hanging arch and the furnace wall is shown in Figure 12.

⑤ Joint ekspansyon orizontal miray founo a jeneralman fèt ak brik ki gen fòm espesyal. Si pa gen brik ki gen fòm espesyal, metòd yo montre nan Figi 13 yo itilize pou masonry. Lè w ap mete jwenti ekspansyon orizontal la, kòd amyant yo ta dwe konprese; wotè brik REFRACTORY yo pi wo a jwenti ekspansyon orizontal la pa ta dwe depase 1m, ak brik REFRACTORY yo ak brik wouj yo ap monte altènativman pou anpeche kòd asbès la konprese ak lakòz miray founo a panche.

(4) Jwenti ekspansyon vètikal la pandye liy lan pou masonry, dan an mal se pa plis pase 3mm, ak kòd la amyant nan jwenti ekspansyon an se yon ti kras pi gwo pase lajè ki rete nan jwenti a ekspansyon pa 3 ~ 5mm, epi li se bourade. nan an menm tan pandan masonry la.

11. Brik REFRACTORY ak brik izolasyon tèmik yo pa gen dwa mouye brik yo, epi brik wouj yo dwe wouze jiskaske deyò a sèk ak andedan an satire anvan brik wouj yo bati.

12. Li pa pèmèt yo trete brik oswa mache sou masonry a, epi li pa pèmèt yo fè fas a sifas la pwosesis nan brik yo nan sifas la flanm dife.

13. Sifas yo nan brik refractory ak brik wouj yo dwe jwenti. Kote pakèt tib konveksyon yo konsantre ak kote Pwodwi pou chodyè yo bloke, zòrèy sann yo dwe grate ansanm ak masonry la.

Construction is often a link that companies tend to ignore. They always think that good products and good designs can guarantee the service life of the kiln. In the national standard, there are strict regulations on the construction of rotary kiln, as follows:
