Ndeapi matanho ekuvaka ekushandisa castables?

Pane zvinhu zvakawanda zvinokanganisa kuita kwezvinokandwa, sekusarudza zvinhu, kuvaka, uye kugadzirisa. Kukosha kwekuvaka kunobatawo basa rinokosha mukushanda kwezvinokandwa. Mupepeti anotevera achakutsanangurira nzira dzinowanzo shandiswa dzekuvaka dzezvinokandwa:

A. Kudurura nzira yekuvaka

1. Kuongorora: Tarisa uone kana mold yakanyatso tsigirwa, hapana makwapa uye kutsauka, uye marara ari muforoma anocheneswa, angave anchors (anodzivirira kupisa simbi palladium zvipikiri) akaiswa weld yakasimba, uye pamusoro pezvitsigiro. yakaputirwa nependi kana bhegi repurasitiki kuti rivhare Simba rekuwedzera mushure mekupisa.

2. Kudururira: Dururira musanganiswa wekudira zvinhu muforoma, isa danda rinozunguza kuti rizungunuke, uye fambisa shamhu inozunguzika nekumhanya kwakafanana, woburitsa zvishoma nezvishoma.

3. Nzvimbo yekudira yakakura kwazvo, inogona kudururwa muzvikamu uye zvikamu, uye inogona kuyambuka-inoshandiswa. Rusvingo runodururwa muzvikamu, nguva imwe neimwe inenge 900mm, kumusoro kwechoto kunoparadzaniswa uye kunodururwa, ndokuzosimudzwa.

4. Kurapa uye kuderedza: tembiricha yezvakatipoteredza> 20 ℃, mold inogona kubviswa mushure me4H, <20 ℃, mold inogona kubviswa mushure mekurapa kwe6-7H, kana mipendero yemunharaunda nemakona zvakakuvadzwa, inogona kugadziriswa. . (Iyo chaiyo yekudhiza nguva zvinoenderana nemamiriro esaiti).

B. Kuzora nzira yekuvaka

1. Chekutanga tarisa kana zvitsigiso (zvinodzivirira kupisa simbi palladium zvipikiri) zvakasungwa zvakasimba. Penda zvibatiso kana kuzviputira mumabhegi epurasitiki kuchengetedza simba rekuwedzera mushure mekudziya.

2. Shandisa manual smearing yemusanganiswa castable zvakananga panzvimbo yekushanda.

3. Nzvimbo yekushanda ichashandiswa nguva dzose muzvikamu kubva pasi kusvika kumusoro. Kureba kwechikamu chimwe nechimwe kunosvika 900mm, uye ukobvu hwega hwega hunosvika 80mm. Kana ukobvu hwasvika paukuru hunodiwa, shandisa chigadziro chekuchenesa nzvimbo yekuvaka.

4. Shandisa nguva dzose pamusoro penzvimbo yekuvaka muzvikamu, nechikamu pakati pemajoini maviri ekuwedzera, nguva imwe neimwe 30-50mm, apo hupamhi hunosvika kuhukuru hunodiwa, shandisa chigadziro chekuputira nzvimbo yekuvaka.

5. Nekupisa kwemafuta ekupisa kwepaipi yakakura-diameter horizontal pipelines, nzira yekugadzira jira muzvikamu kutanga uye kumisa kubatana kunofanira kugamuchirwa. Kana pombi yagadzirwa muzvikamu, isa pombi yakachinjika, isa iyo yepasi semicircular lining kutanga, uye mushure mekurapa kwechisikigo kwe4-8h, shandura pombi 180 ° uye isa imwe semicircular lining, uye ita kurapwa kwakabatana mushure mekunge pombi yapera. zvakabatana.

C. Kupfapfaidza nzira yekuvaka

1. Weld simbi palladium zvipikiri kana simbi mesh (heat-resistainless simbi) pachoto goko kutanga.

2. Isa pendi yekupfapfaidza musprayer, shandisa mhepo yakamanikidzwa (pressure 0.10-0.15MPa) kutumira musanganiswa kumuromo, uye wedzera huwandu hwakakodzera hwemvura kana makemikari bonding agent kuti usanganise nezvinhu, womwaya kune nzvimbo yekuvaka.

3. Kubuda kwenozzle kunofanira kunge kuri perpendicular kune nzvimbo yekuvaka, chinhambwe chiri 1-1.5m, kupfapfaidza kunofanira kuramba kuchienderera, uye ukobvu hwekupfapfaidza kwega kwega kunofanira kunge kuri pasi pe200mm.

4. Kana iyo yekupfapfaidza yenzvimbo yekuvaka yakanyanya kuwanda, inofanirwa kupfapfaidzwa muzvikamu, asi inofanira kuitwa mushure mekunge tambo yapfuura ine simba rakakwana. Mushure mekupfapfaidza, nzvimbo yekushanda inofanirwa kuve yakatsetseka uye iyo rebound zvinhu zvinofanirwa kucheneswa.

Kupfupisa, kunyatsotevera nzira dzekuvaka uye matanho anoita basa rakakosha mukuita refractory castables.
