Iskimu sokwakhiwa kwezixhobo ezichasayo zokufakelwa kwenxalenye nganye yesithando sokubhaka i-carbon

Inkqubo yokwakhiwa kwe-lining yecandelo ngalinye lesithando sokubhaka i-carbon ihlelwe ngumenzi wezitena eziphikisayo.

1. Inkqubo yokwakhiwa kwezitena zodonga lwendlela yomlilo:

(1) Ulungiselelo lokwakha:

I-1) Ngaphambi kokungena kwindawo, izinto eziphikisayo kufuneka zihlolwe ngokungqongqo ukuba ubuninzi babo kunye nomgangatho wabo uhlangabezana neemfuno zoyilo. Emva kokungena kwisiza, kufuneka baphakanyiswe kwindawo yokwakha nge-crane kwiibhetshi.

2) Khupha imigca yeziko elithe nkqo nelithe tyaba kunye nemigca yokuphakama ethe tyaba yesithando somlilo kwaye uyiphawule, kwaye ujonge kwakhona ngaphambi kokwakhiwa ukuze uqinisekise ukuba bafanelekile.

3) Ukulinganisa i-furnace bottom, usebenzisa i-425 cement 1: 2.5 (umlinganiselo wobunzima) udaka lwesamente lokulinganisa. Emva kokuba udaka lwesamente luqinisiwe, zoba umgca wokwakhiwa kwezitena eziphikisayo ngokomgca osembindini wegumbi lesithando somlilo kunye nomgca ophakathi wodonga oluthe tye, kwaye ukhangele ukuba ubungakanani bayo buhlangabezana neemfuno zoyilo, kwaye emva koko uqalise i-masonry.

(2) Ulwakhiwo olusezantsi lweziko:

1) Ukwakhiwa kwezantsi kwesithando somlilo: okokuqala sebenzisa izitena ezisemgangathweni zodongwe ukwakha izitena zesitena ngokude kwi-oven ezantsi, kwaye emva koko ugubungele umphezulu ongaphezulu kunye neebhloko ezifakwe ngaphambili ukuze wenze i-oven overhead bottom.

2) Ukwakhiwa komgangatho wokugquma kwesithando somlilo: i-1 ukuya kwi-5 imigangatho ye-diatomite ye-thermal insulation refractory izitena ezinobunzima be-masonry ye-0.7g / cm, kunye ne-6 ukuya kwi-8 yemigangatho yezitena ze-alumina ezikhaphukhaphu ezinobunzima be-masonry ye-0.8g / cm .

3) Ukwakhiwa kwezitena zomgangatho: Izitena ezimbini zezitena ezinobumba obukhethekileyo zisetyenzisiweyo, nganye inobunzima be-100mm. Ngaphambi kobume, thatha ukuphakama komgangatho ongaphezulu wesithando somlilo njengesalathiso, khupha umgca wokuphakama komgangatho kwaye uphawule, kwaye emva koko uqale i-masonry. Kwi-masonry enamalungu adibeneyo, amajoyina okwandiswa kufuneka azaliswe ngodaka olukhanyelayo kwaye luzele.

(3) Ukwakhiwa kweendonga ezijikelezileyo:

Phawula umgca ngokuhambelana nomgca ophakathi, kwaye usethe inani leentonga zesikhumba ekudibaniseni kunye nodonga oluthe tye ukulawula nokulungelelanisa ukuphakama komgangatho ngamnye ukuphepha ukuphambuka okugqithisileyo. Ngethuba lenkqubo ye-masonry, umgangatho we-masonry uya kuhlolwa nangaliphi na ixesha ukuze kuqinisekiswe ukuba i-flatness, i-verticality yodonga kunye nobukhulu obugciniweyo bokudibanisa ukwandiswa kuhlangabezana neemfuno zokuyila kunye nokwakhiwa. Udaka oluchasayo kwindawo yokwandisa luzaliswe, kwaye indawo yokwakha iyacocwa xa udonga lomile ukuya kuma-70%.

(4) Ukwakhiwa kweendonga ezithe tye:

Ngethuba lokwakhiwa kweendonga ezinqamlekileyo zodonga, ngenxa yokuba udonga olunqamlekileyo lwesiphelo kunye nodonga oluphakathi luyintlobo ezahlukeneyo zezitena, ngamnye umqhubi unikezwa umzobo owenziwe ngezitena ngexesha lokumisa. Uluhlu lokuqala lwezitena kufuneka lubekwe ngaphambili, lushiye i-grooves eludongeni lomsele womlilo. Ukongezelela, ukuphakama komgangatho we-40 wodonga oluthe tye luyi-1-2mm ephantsi kunomgangatho we-40 wodonga lwendlela yomlilo. Ngethuba lenkqubo yokumisa, ukuphakama kwodonga kufuneka kulawulwe ngumgca wokulawula kwindonga yecala. Umdibaniso wokwandisa phakathi kodonga oluthe tye kunye nodonga olusecaleni luya kupakishwa ngokuqinileyo.

(5) Ukwakhiwa kweemasonry zemijelo yomlilo kunye nemijelo yokucima umlilo:

Ubume bezitena zodonga lwendlela yomlilo:

1) Xa ukwakhiwa kwezitena zodonga lomlilo, ngenxa yenani elikhulu lezitena, abasebenzi bokwakha kufuneka baqhelane nemizobo yokubeka izitena, kwaye akukho zixhobo ezingaphezu kwe-13 zakhiwe ngosuku, kwaye ama-vertical joints awadingi. uzaliswe ludaka oluqhankqalazayo.

2) Khangela ukuphakama okusisiseko kunye nomgca ophakathi we-roaster phambi kwe-masonry kwaye wenze uhlengahlengiso ngexesha elifanelekileyo, kwaye usebenzise isanti eyomileyo okanye izitena eziphikisayo zokulinganisa unyango.

3) Ukuphakama kodonga lwesithando somlilo kufuneka kulawulwe ngokungqongqo ngokuhambelana nobukhulu bomgca xa kwakhiwa izitena zodonga lomjelo womlilo, kwaye umlawuli kufuneka asetyenziswe nangaliphi na ixesha ukujonga ukuthambeka kodonga olukhulu.

I-4) Isikhundla esigciniweyo kunye nobukhulu bokudibanisa ukwandiswa kufuneka kuhlangabezane neemfuno zokuyila, kwaye i-debris kwi-joint kufuneka ihlambuluke ngaphambi kokuba izaliswe ngodaka oluphikisayo.

I-5) Ukudibanisa kunye nokudibanisa okuthe nkqo kwezitena eziphikisayo kwindawo engezantsi yesitena sokuvala umjelo womlilo akuyi kuzaliswa ngodaka oluphikisayo.

6) Ibhloko eyenziwe ngaphambili yenziwe njengoko ifunwa phambi kofakelo, kwaye ukuphambuka okuvumelekileyo kobungakanani bebhloko elungiselelwe kwangaphambili kufuneka kube ngaphakathi kwe-± 5mm.

Ubume bezitena obudibanisa udonga lomjelo womlilo:

Umjelo womlilo wokudibanisa unokwakhiwa ngokuzimeleyo okanye ngokuhambelana nodonga olunqamlezayo. Xa ukwakhiwa kwe-thermal insulation layer, izinto eziphathekayo, ubuninzi, inani leengqimba, kunye nesakhiwo sokwakhiwa kwezitena ezilula zokufakelwa kwe-thermal kufuneka zihlangabezane neemfuno zoyilo.

(6) Ufakelo kuphahla lweziko:

Ufakelo lwebhloko esele lufakwe eluphahleni lwesithando somlilo kufuneka luqale ukusuka kwelinye icala, faka kuqala indawo ephezulu ukudibanisa umjelo womlilo, emva koko uphakamise ibhloko ephoswe ngaphambili kwindawo ephezulu yodonga lomjelo womlilo, kwaye ekugqibeleni ufake i-castable precast. ibhlokhi eludongeni oluthe tye. Xa ufaka inxalenye ephezulu yomzila womlilo, kuyimfuneko ukuzalisa i-75mn zirconium equkethe i-fiberboard ye-thermal insulation phantsi kwe-castable.
