Parizvino, hapana yakadzama yenyika chiyero chekuvaka refractory castables, asi kune yakajeka yekuongorora uye yekuona zviyero zvezvakasiyana zvinhu zvinoramba mune yenyika standard GB/T yezvinhu zvinoramba.Iwe unogona kunongedzera kune aya zviyero kuyera kuvakwa kwezvinokandwa.Ngatimbotaura nezvavo muchidimbu.
Mazhinji anokandwa anogona kuongororwa uye kuyedzwa zvichienderana neyazvino yenyika chiyero Test Method yeThermal Kuwedzera kweRefractory Materials (GB/T7320).Iyo refractory castables lining inodururwa maererano nezvinodiwa zvinotevera:
1. Nzvimbo yekuvaka inofanira kutanga yacheneswa.
2. Kana marefractory castables asangana nezvidhinha zvinoramba kana zvigadzirwa zvekupisa zvinopisa, matanho ekudzivirira mvura anotorwa kuti azvitsaure.Panguva yekuvaka, mapuranga efuro uye machira epurasitiki anogona kushandiswa kuvaparadzanisa, uye anogona kubviswa mushure mekuvaka.
Mugadziri anokandwa anokuyeuchidza kuti pamusoro peiyo formwork inoshandiswa kudururira mbambo yechoto inofanirwa kuve yakatsetseka, nekuomarara kwakakwana uye kusimba, uye kumisa uye kubviswa kweiyo formwork ine nyore chimiro kunofanirwa kuzadzisa zvinotevera zvinodiwa:
1. Rutsigiro ruchaiswa zvakasimba uye kubviswa kuitira kuti pasave nekudonha kwedhaka pamubatanidzwa.Iyo bheti yehuni yakachengeterwa yekuwedzera yejoint ichasimbiswa zvakasimba kudzivirira kutamiswa panguva yekudengenyeka.
2. Kune refractory castables ine corrosivity yakasimba kana kubatana, yekuzviparadzanisa layer ichaiswa muformwork kutora anti cohesiveness matanho, uye inotenderwa kutsauka kwechaiyo ukobvu kutungamira dimension ndeye +2 ~ - 4mm.Formwork haizoisirwe pane yakadirwa castable kana simba rayo risingasviki 1.2MPa.
3. Iyo formwork inogona kumiswa yakachinjika muzvikamu uye zvikamu kana mumabhuroko panguva dzakasiyana.Kureba kweimwe neimwe formwork erection kuchatemerwa zvichienderana nezvinhu zvakaita seyakadzika tembiricha yekudurura kumhanya kwenzvimbo yekuvaka uye nguva yekumisikidza yevanokanda.Kazhinji, haifaniri kudarika 1.5m.
4. Mutoro unotakura formwork uchabviswa kana castable inosvika 70% yesimba.Iyo isingatakure-inotakura formwork ichabviswa kana iyo inokandwa simba inogona kuve nechokwadi kuti iyo yevira yekubikira pamusoro uye makona haizokuvadzwa nekuda kwekudhiza.Iyo inopisa uye yakaoma castables ichabikwa kune yakatarwa tembiricha isati yabviswa.
5. Kukura kwegap, nzvimbo yekugovera uye chimiro chekuwedzera kwejoint of integrally cast furnace lining ichaenderana nekugadzirisa zvirongwa, uye zvinhu zvichazadzwa maererano nekugadzirisa zvirongwa.Kana iyo dhizaini isingatsanangure iyo gap saizi yejojo yekuwedzera, avhareji kukosha kwekuwedzera kwejointi pamamita echoto lining.Iyo yepamusoro yekuwedzera mutsara wechiedza refractory castable inogona kusetwa panguva yekudira kana kucheka mushure mekudururwa.Kana huni hwebindu hwechoto hwakakura kupfuura 75mm, hupamhi hwemutsara wekuwedzera hunofanira kuva 1 ~ 3mm.Kudzika kunofanirwa kunge kuri 1/3 ~ 1/4 yehuni hwebindu ukobvu.Nzvimbo yemutsara wekuwedzera inofanira kuva 0.8 ~ 1m zvichienderana nechimiro chetsime.
6. Kana ukobvu hwe insulating refractory castable lining iri ≤ 50mm, manual coating method inogonawo kushandiswa kuenderera mberi kudira uye manual tamping.Mushure mekudururira, iyo lining surface inofanira kunge yakadzikama uye yakaoma pasina kupukuta.
Ukobvu hwemwenje unodzivirira refractory castable lining δ<200mm, uye zvikamu zvine kurerekera kwechoto lining pamusoro zvisingasviki makumi matanhatu zvinogona kudururwa nemaoko.Paunenge uchidurura, inofanira kugoverwa zvakaenzana uye inoramba ichidururwa.Sando yerabha kana sando yemapuranga ichashandiswa kubatanidza zvikamu nesando imwe nehafu muchimiro chepuramu.Mushure mekumisikidzwa, iyo inotakurika ndiro vibrator ichashandiswa kuzunguza uye kubatanidza iyo yevira yebira pamusoro.Iyo mbiru yevira yevira ichave yakati sandara, yakakora uye isina zvidimbu zvinyoro.
