Njengamanje, alikho indinganiso kazwelonke enemininingwane yokwakhiwa kwama-castable aphikisayo, kodwa kukhona amazinga acacile okuhlola nokutholwa kwezinto ezihlukahlukene eziphikisayo ku-GB/T ejwayelekile kazwelonke yezinto eziphikisayo.Ungabhekisela kulawa mazinga ukuze ulinganise ukwakhiwa kwama-castable.Ake sikhulume ngazo kafushane.
Ama-castable amaningi angahlolwa futhi ahlolwe ngokuya Ngendlela Ejwayelekile kazwelonke Yokuhlola Yokwandisa Okushisayo Kwezinto Eziphikisayo (GB/T7320).I-refractory castable lining izothelwa ngokuhambisana nalezi zinhlinzeko ezilandelayo:
1. Indawo yokwakha kufanele ihlanzwe kuqala.
2. Uma izinsimbi eziqinile zithintana nezitini eziphikisayo noma imikhiqizo ye-thermal insulation, izinyathelo zokulwa nokumuncwa kwamanzi kufanele zithathwe ukuze zihlukaniswe.Ngesikhathi sokwakhiwa, amabhodi e-foam nendwangu yepulasitiki angasetshenziswa ukuze ahlukanise, futhi angasuswa ngemva kokwakhiwa.
Umkhiqizi ohlakazekayo uyakukhumbuza ukuthi ingaphezulu lefomu elisetshenziselwa ukuthulula ulayini lwesithando somlilo kufanele libe bushelelezi, libe nokuqina okwanele namandla, futhi ukumiswa nokususwa kwefomu ngesakhiwo esilula kufanele kuhlangabezane nalezi zidingo ezilandelayo:
1. Usekelo luzofakwa luqinile futhi lususwe ukuze kungabikho ukuvuza kodaka endaweni ehlangene.I-batten yokhuni egcinelwe ukunwetshwa kwejoyinti izomiswa iqine ukuze kugwenywe ukugudluzwa phakathi nokudlidliza.
2. Kuzinto ezihlakazekayo eziphikisayo ezinokugqwala okuqinile noma ukuhlangana, ungqimba oluhlukanisayo luzosethwa ngendlela yokwenza ukuze kuthathwe izinyathelo zokulwa nokuhlangana, futhi ukuchezuka okuvumelekile kobukhulu obunembile besiqondiso ngu+2~- 4mm.I-formwork ngeke ifakwe ku-castable ethululwayo lapho amandla ayo engafinyeleli ku-1.2MPa.
3. I-formwork ingamiswa ivundlile ibe izendlalelo nezigaba noma ngamabhulokhi ngezikhathi ezithile.Ubude bokumiswa kwefomu ngalinye kuzonqunywa ngokuya ngezici ezifana nezinga lokushisa elizungezile lokuthulula lendawo yokwakha kanye nesikhathi sokumiswa kwezinsimbi.Ngokuvamile, akufanele idlule 1.5m.
4. Ifomu elithwala umthwalo lizosuswa lapho okuphonswayo kufinyelele ku-70% wamandla.I-formwork engathwali imithwalo izosuswa lapho amandla okuphonswa angaqinisekisa ukuthi ulayini lwesithando somlilo namakhona angeke wonakaliswe ngenxa yokudilizwa.Ama-castable ashisayo naqinile azobhakwa ezingeni lokushisa elishiwo ngaphambi kokususwa.
5. Usayizi wegebe, indawo yokusabalalisa kanye nesakhiwo sokunwetshwa kwejoyinti lolayini wesithando somlilo ohlanganisiwe kufanele uhambisane nezinhlinzeko zokuklama, futhi izinto ezisetshenziswayo zizogcwaliswa ngokuvumelana nezinhlinzeko zokuklama.Uma umklamo ungacacisi usayizi wegebe lejoyinti lokunweba, inani elimaphakathi lejoyinti lokunweba ngemitha ngayinye yolayini lwesithando somlilo.Umugqa wokunwebeka ongaphezulu we-light refractory castable ungasethwa ngesikhathi sokuthululwa noma ukusika ngemva kokuthululwa.Uma ubukhulu belayini yesithando somlilo bukhulu kuno-75mm, ububanzi bomugqa wokunweba kufanele bube ngu-1 ~ 3mm.Ukujula kufanele kube ngu-1/3~1/4 wogqinsi lolayini lwesithando somlilo.Isikhala somugqa wokunweba kufanele sibe ngu-0.8 ~ 1m ngokuya ngokuma komthombo.
6. Uma ubukhulu be-insulating refractory castable lining bungu-≤ 50mm, indlela yokugqoka ngesandla ingasetshenziselwa ukuthululwa okuqhubekayo kanye nokunyathela ngesandla.Ngemuva kokuthulula, i-lining surface kufanele ibe flat futhi iminyene ngaphandle kokupholisha.
Ubukhulu belayini elikhanyelayo elivikelayo elivikelayo elingu-δ< 200mm, futhi izingxenye ezinokuthambekela kolayini lwesithando somlilo ngaphansi kuka-60 zingathelwa ngesandla.Lapho uthela, uzosatshalaliswa ngokulinganayo futhi uthululwe ngokuqhubekayo.Isando senjoloba noma isando sokhuni sizosetshenziswa ukuhlanganisa izingxenye ngesando esisodwa nesando esinguhhafu esimweni seplamu.Ngemuva kokuminyanisa, isidlidlizi sepuleti eliphathwayo sizosetshenziswa ukudlidliza futhi sihlanganise ulayini lwesithando somlilo.Indawo yolayini lwesithando somlilo kufanele ibe isicaba, iminyene futhi ingabi nezinhlayiya ezixegayo.
