Ukulungiselela kanye nenqubo yokusebenza kwe-refractory spray coating ye-blast furnace hot blast stove

Imithetho yokwakha yezifutho eziphikisayo zezitofu eziqhumayo zesithando somlilo ziqoqwa abakhiqizi bezitini abaphikisayo.

Ukwakhiwa kwesifutho sikapende kuyinqubo ebaluleke kakhulu yezitofu eziqhumayo ezishisayo. Izinga lokwakhiwa komugqa wepende yesifutho liyisiqinisekiso sokutywinwa komzimba wesithando somlilo nokusebenza kokugcina ukushisa. Ukwakhiwa kokufafaza kunokuqhubeka okuqinile, futhi inqubo yokufafaza kufanele ilungise ngokunengqondo ukucindezela komoya kanye nokwengezwa kwamanzi ngokwebanga lokudiliva kanye nokuphakama kokwakhiwa kopende ofuthwe esizeni. Umsebenzisi kufanele abe nesipiliyoni sokwakha ngopende wesifutho esinekhono.

1. Ukulungiselela ngaphambi kokufafaza:

(1) Hlola futhi uqinisekise ukuthi izimpande zezinzipho okusetshenzwa kulengwa kuzo zishiselwe ngokuqinile (kuyizinga lekhwalithi ukuthi izipikili zehange zigobe futhi zingawi ngokushaya izipikili zehange ngesando sesandla), futhi ayikho into efana nokuhlanganisa. noma desoldering. Ukucaciswa nokuhlukaniswa kwezipikili zokubambelela kuhlangabezana nezidingo zokuklama nezokwakha. .

(2) Lungisa iphutha lempahla yokwakha yokufutha, izinto zikagesi, njll. ukwenza umfutho wazo womoya osebenzayo kanye nomfutho wamanzi uhlangabezane nezindinganiso ezishiwo futhi uphumelele ukusebenza kwesilingo.

(3) Inani likapende wesifutho kufanele lihlangabezane nezidingo zemisebenzi eqhubekayo yokwakha. Ingxenye yezinto zokusetshenziswa namanzi angeziwe kufanele yenziwe ngokuhambisana ngokuqinile nemiyalelo yokusetshenziswa neyokwakha. Ngemuva kokuthi isifutho sesilingo sesifanelekile, ukwakhiwa okusemthethweni kungenziwa.

(4) Hlola isisindo sokuhlola sepuleti elilengayo lokwakhiwa kokufutha, ukuhlola kuyasebenza, intambo yokuphepha, indawo yokuphakamisa, njll., hlola futhi uqinisekise ikhwalithi nokuphepha, futhi uqinisekise ukuzinza nokushelela kweqiniso- isignali yokuxhumana yesikhathi phakathi kwezinhlangothi ezingenhla nezingezansi.

(5) Hlola ukuthi i-grid plate ifakwe endaweni futhi uhlole ukuze uqinisekise ukuthi iyahlangabezana nezidingo zokuklama nezokwakha.

2. Inqubo yokusebenza yokwakhiwa kwepende yesifutho:

(1) Ngaphambi kokufafaza, gxuma ngokulinganayo upende wesifutho ngokwemiyalelo yokuwulungiselela, bese uwubeka emshinini wokufafaza, bese uvula umshini wokufutha ukuze ufunzwe umoya kanye nezinto ezibonakalayo.

(2) Ngaphambi kokufutha, hlanza indawo yokwakha ngomoya ocindezela kakhulu bese uyimanzisa ngamanzi ngaphambi kokufutha.

(3) Uhlelo lokusebenza lokufafaza luwukunikezwa komoya → ukuphakelwa kwamanzi → ukudla okubalulekile, futhi ukulandelana kuyahlehliswa lapho ukufuthwa kuyekwa.

(4) Ukufafaza kwengxenye yesilinda esiqondile kufanele kube kusuka phezulu kuye phansi, ukusuka kwesokunxele kuye kwesokudla, futhi isibhamu sokufutha siyehla kancane kancane sigudle isiqondiso sokuzungeza. Ubukhulu besifutho ngasinye kufanele bulawuleke phakathi kuka-40-50mm, futhi izingxenye ezinogqinsi olungaphezu kuka-50mm kufanele zihlukaniswe zibe izingxenye ezimbili. Noma ukufafaza izikhathi eziningi ukuze kuhlangatshezwane nezidingo, ukwakhiwa kokufafaza phezulu kwe-arch kufanele kuzungezwe kusuka phansi kuya phezulu.

(5) Isibhamu sokufutha kufanele sibe perpendicular endaweni yokwakha futhi ibanga kufanele kube 1.0 ~ 1.2m, futhi umfutho womoya kanye nomfutho wamanzi kufanele kulungiswe noma nini ngokuvumelana nezimo zesayithi; inani lokufafaza kufanele lisekelwe ekwehleni okuncane kwamanzi ebusweni be-coating, futhi idinga ukuhlukaniswa izikhathi ezimbili noma ngaphezulu. Ngokufafaza izingxenye zokwakha, isikhathi sokufafaza esiphezulu nesiphansi kufanele silawulwe phakathi nesikhathi sokuqala sokusetha.

(6) Indawo ehlanganyelwe enwetshiwe ehlanganisiwe yongqimba olunamathelayo lwesifutho kufanele ibe esigabeni ngasinye noma ijoyinti yegridi yesikwele. Ngemuva kokuthi ukufafaza kuphazamisekile noma kuphazamiseke kancane, indawo ephazamisekile kufanele ifafazwe ngesendlalelo sokumboza futhi ilunga eliphazamisekile kufanele lifafazwe ngamanzi kuqala. Ukwakhiwa kungenziwa kuphela ngemva kokuba manzi.

(7) Phakathi nenqubo yokwakha, hlola ukujiya kanye ne-radius yesendlalelo sokufufaza nganoma yisiphi isikhathi futhi uzilungise ngesikhathi ukuze uqinisekise ukuthi ziyahlangabezana nezidingo zokuklama nezokwakha.

(8) Ngemva kokwakhiwa kwesigaba/indawo ngayinye ye-refractory spray coating sekuqediwe, qala ukwelashwa kweleveli, ukulungisa okungalungile kokuqala, ngemva kokuqeda nokushelela indawo enkulu ye-concave, sebenzisa i-radius gauge noma ibhodi le-arc ukuze uyileveli kahle futhi. .
