Integral masonry process uye kuvaka kiyi mapoinzi erefractory lining yegoridhe yekugocha choto.

Iyo refractory yekuvaka chirongwa chegoridhe rekugocha cheni body inounganidzwa uye yakabatanidzwa nemugadziri wezvidhinha refractory.

1. Kudururwa kwekuvakwa kwerefractory castable pabhodhi rekugovera revira rekugocha:

(1) Mushure mekunge goko rechoto uye vharanda rechoto chekugocha zvavakwa uye zvapasa kuongororwa uye kugamuchirwa, dhizaini yekugovera refractory castable kuvaka ichatangwa. Hukuru hwechikamu chimwe nechimwe huchatariswa uye midzimu yemhepo yakamisikidzwa ichaiswa. Nzvimbo yekuvaka ichacheneswa uye muromo uchavharwa. Kudurura kunogona kuitwa chete pashure.

(2) Dururirai light-weight thermal insulation inokandwa kutanga, wobva wadira heavy-weight refractory castable. Izvo zvinokandwa zvinosanganiswa nemuvhenganisi wakamanikidzwa, uye musanganisi anoshambidzwa nemvura yakachena kuti ave nechokwadi chokuti yakachena uye isina tsvina.

(3) Iyo yakapedzwa inokandwa inogona kugadzirwa zvakananga mushure mekuwedzera mvura uye kubvongodza zvinoenderana nebhuku remirayiridzo. Izvo zvinokandwa zvinofanira kugadzirwa zvinofanira kuenzaniswa nemazvo. Wedzera maaggregates, powders, binders, nezvimwewo mumusanganisi, sanganisa zvakanaka, uye wobva wawedzera huwandu hwakakodzera hwemvura kuti usanganise kwemaminitsi maviri kusvika matatu kuvakwa kusati kwashandiswa.

(4) Iyo yakasanganiswa castable inofanira kudirwa panguva imwe mukati memaminitsi makumi matatu.

(5) Zvikamu zvakaiswa pakutanga hazvizoshandiswe. Panguva yekuvakwa kwezvinokandwa, vibrator inofanirwa kushandiswa kutenderedza painodurura.

(6) Kuvakwa kweiyo inokandwa pamubhedha wemvura inoyerera inofanira kupedzwa panguva imwe chete, uye hapana chikonzero chekuchengeta majoini ekuwedzera.

(7) Pamusoro peiyo inokandwa layer inodiwa kuti ive yakatsetseka uye yakati sandara. Maawa makumi maviri nemana mushure mekupedzwa kwekudira, kudiridza nekurapa kunofanira kuitwa. Nguva yekurapa haisi pasi pemazuva matatu, uye tembiricha yekurapa inofanira kunge iri 24-3 ° C.

2. Masonry kuvakwa kwezvidhinha zvinopisa zvekugocha muviri wechoto:

(1) Refractory zvidhinha masonry zvinodiwa:

1) Refractory zvidhinha masonry inofanira kuvakwa nekukanya uye kudzvanya nzira (kunze kwekushandurwa kwakakosha senge zvidhinha zvakakura), uye saizi yejoinhi yekuwedzera ichachengetwa sezvinodiwa, uye dhaka rinoramba riri mujoini richazadzwa zvakasimba uye zvizere.

2) Nzvimbo yezvidhinha zvinoramba uye ukuru hwezvibatanidza zvekuwedzera zvinogona kugadziriswa uchishandisa matanda kana rubber slabs. Iyo yakapedzwa refractory masonry yezvidhinha haifaniri kubonderana kana kugogodza pairi.

3) Munguva yekugadzira masonry, shandisa yakakwira-concentration refractory dhaka yekurapa majoini pamberi pejoinhi yekuwedzera yasimbiswa.

4) Zvidhinha zvinoramba zvichigadziriswa nekucheka zvidhinha. Nzvimbo yakagadziriswa haifaniri kutarisana nedivi rechoto uye mubatanidzwa wekuwedzera. Kureba kwechidhinha chakagadziridzwa hakuzove pasi pehafu yehurefu hwechidhinha chepakutanga, uye hupamhi (ukobvu) hwechidhinha chakagadzirwa hachizove pasi pehupamhi hwechidhinha chepakutanga (Kukora) 2/3 yedhigirii. .

5) Paunenge uchivaka madziro echoto chinopindirana, tarisa kukwidziridzwa kwese chero nguva uye usimudze kumusoro nedhiri. Paunenge uchisiya kana kugadzirazve uye kuputsa, inofanira kusiiwa sechamfer yakatsikwa.

(2) Refractory slurry kugadzirira:

Iyo refractory dhaka yemetallurgical yekugocha muchoto masonry inofanirwa kugadzirwa nedhaka refractory rinoenderana nezvinhu zverefractory zvidhinha masonry. Refractory slurry inofanira kugadzirirwa nekusanganiswa ne slurry mixer. Edza kusashandisa mudziyo wekusanganisa wakafanana kune refractory slurries yezvinhu zvakasiyana. Kana iyo refractory slurry ichifanira kutsiviwa, mudziyo wekusanganisa uye mudziyo unofanirwa kusukwa nemvura yakachena, uye ipapo izvo zvinofanirwa kuchinjwa kuti zvisanganise. Iyo viscosity ye refractory dhaka inogona kudzorwa zvinoenderana ne-pa-saiti yekuvaka mamiriro, uye refractory dhaka iro rakatanga kuiswa harizoshandiswe.

(3) Furnace wall refractory brick masonry kuvaka:

1) Zvidhinha zvinoramba zvemadziro evira zvinofanira kuvakwa muzvikamu. Pamberi pega pega chikamu chemadziro echoto chavakwa, maviri akaturikidzana e graphite upfu girazi remvura rinofanira kuzorwa pamadziro emukati megoko rechoto, uye ipapo asbestos insulation board inofanira kunamirwa zvakasimba pane smear layer, uye ipapo choto Masonry kuvaka. zvezvidhinha zvisingaremi uye zvidhinha zvinorema.

2) Chikamu chimwe nechimwe chemadziro evira chinofanira kuvakwa negoko rechoto semasonry sideline, uku uchivimbisa kupfava kwemukati wechoto.

3) Kana zvikamu zvemasonry zvine thermal insulation lining, zvidhinha zvinorema zvinorema zvinofanirwa kuiswa kune imwe urefu usati waisa zvinorema-huremu refractory zvidhinha zvekushanda lining.

4) Paunenge uchivaka nzvimbo yegomba, nzvimbo yekuvhura gomba inofanira kutanga kuvakwa, uye rusvingo rwechoto rwakapoteredzwa runofanira kuvakwa kumusoro, uye zvidhinha zvekuvhara zvega rega rezvidhinha zvinoputika zvichagoverwa zvakaenzana.

(4) Vault masonry kuvaka:

1) Maererano nemutsara wepakati wechoto chinopisa, tanga kuvaka zvidhinha-tsoka kuitira kuti kukwirira kwepamusoro kuchengetwe pamutsara wakafanana.

2) Iyo arch-tsoka zvidhinha zvidhinha zvine chimiro chakasarudzika uye yakakura muhukuru, saka nzira yekukwesha haina kukodzera kugadzira. Panguva yekuvaka, pamusoro pezvidhinha zvinoramba zvinofanira kusvibiswa nehuwandu hwakakodzera hwedhaka refractory kuita kuti zvidhinha zviri pedyo zvinoramba zvive nehukama hwepedyo uye hwakanaka.

3) Mushure mokunge zvidhinha zve-arch-foot zvapedzwa uye zvakapfuura kuongororwa, tanga kuvaka mhete yekutanga yezvidhinha, uye wozovaka mhete yechipiri mushure mokunge mhete yekutanga yezvidhinha yakavakwa. Iyo masonry process inoda kuti mukaha pakati pevault zvidhinha uve wakasimba. Ukuru hwemajoini ekuwedzera akachengetedzwa hunofanirwa kunge hwakafanana sezvinobvira.

4) Zvidhinha zvekuvhara gonhi zvemhete imwe neimwe yevhavha inofanira kugoverwa zvakaenzana padenga rechoto, uye hupamhi hwemasuo ekuvhara masuo haafaniri kuva pasi pe7/8 yezvidhinha zvepakutanga, uye mhete yekupedzisira inofanira kuva. yakadirwa nezvinokandwa.

(5) Kuwedzera mubatanidzwa kuvaka:

Chinzvimbo uye saizi yeakachengeterwa majoini ekuwedzera echoto chemuviri masonry anofanirwa kuiswa zvinoenderana nedhizaini uye kuvaka zvinodiwa. Zvisungo zvinofanira kucheneswa zvisati zvazadza majoini ekuwedzera, uye zvinhu zvinoramba zvekugadzirwa kwezvinhu zvinofanira kuzadzwa maererano nezvinodiwa. Kuzadza kunofanira kunge kwakafanana uye kwakaoma, uye pamusoro payo inofanira kuva yakanyorova. .
