1. Karfe fiber ƙarfafa refractory castables don siminti kiln
Ƙarfe fiber ƙarfafa castables, yafi gabatar da zafi-resistant bakin karfe zaruruwa a cikin kayan, sabõda haka, abu ya sami mafi girma ƙarfi da thermal girgiza juriya, game da shi yana ƙara lalacewa juriya da sabis na kayan. Ana amfani da kayan galibi don ɓangarorin da ba su da zafi mai zafi kamar su bakin kiln, bakin ciyarwa, tudun da ke jure lalacewa da rufin tukunyar wutar lantarki.

2. Ƙananan simintin siminti don kiln siminti
Ƙananan simintin simintin gyaran gyare-gyare sun haɗa da manyan alumina, mullite da corundum refractory castables. Wannan jerin samfurori yana da halaye na ƙarfin ƙarfi, anti-scouring, juriya na juriya da kyakkyawan aiki. A lokaci guda, ana iya sanya kayan zuwa simintin toya mai saurin fashewa bisa ga buƙatun lokacin yin burodin mai amfani.

3. Ƙarfin alkali mai jure wa simintin siminti
Ƙarfin alkali-resistant castables suna da kyau juriya ga yashewa ta alkaline gas da slag, kuma suna da dogon sabis rayuwa. Ana amfani da wannan kayan galibi don murfi kofa, murhun bazuwar, tsarin preheater, tsarin gudanarwa, da dai sauransu da sauran rufin kiln masana'antu.

Hanyar gine-ginen simintin ƙaramar siminti mai ƙaƙƙarfan aluminium don rufin kiln rotary
Gina babban siminti mai ƙarancin aluminium don rufin kiln rotary yana buƙatar kulawa ta musamman ga matakai guda biyar masu zuwa:

1. Ƙaddamar da haɗin gwiwar fadadawa
Dangane da ƙwarewar da ta gabata ta yin amfani da manyan simintin siminti na aluminum, haɓaka haɗin gwiwa shine maɓalli mai mahimmanci da ke shafar rayuwar sabis na rotary kiln castable linings. An ƙaddara haɗin haɓaka yayin zubar da rufin kiln rotary kamar haka:

(1) Ƙungiyoyin da'ira: sassan 5m, 20mm aluminum silicate fiber ji an yi sandwiched a tsakanin simintin gyaran kafa, kuma an haɗa zaruruwa bayan fadadawa don rage yawan damuwa.

(2) Ƙaƙƙarfan haɗin gwiwa: Kowane yanki guda uku na simintin an yi shi tare da plywood mai zurfi 100mm a cikin kewayen ciki, kuma an bar haɗin gwiwa a ƙarshen aiki, don jimlar 6 tube.

(3) Yayin zubawa, ana amfani da fitilun shaye-shaye guda 25 a kowace murabba'in mita don sakin wani ƙayyadaddun damuwa na faɗaɗawa yayin da suke gajiyar kiln.

2. Ƙayyade yawan zafin jiki na gini
The dace yi zafin jiki na high-aluminum low-ciment castables ne 10 ~ 30 ℃. Idan yanayin zafi ya yi ƙasa, yakamata a ɗauki matakai masu zuwa:

(1) Rufe mahallin ginin da ke kewaye, ƙara wuraren dumama, da hana daskarewa sosai.

(2) Yi amfani da ruwan zafi a 35-50 ℃ (kayyade ta wurin zubar da girgizar gwaji) don haɗa kayan.

3. Cakudawa
Ƙayyade adadin haɗuwa a lokaci ɗaya bisa ga ƙarfin mahaɗin. Bayan an ƙayyade adadin hadawa, ƙara kayan simintin a cikin jakar da ƙananan abubuwan da ke cikin jakar a cikin mahaɗin lokaci guda. Da farko a fara mahaɗin ya bushe ya bushe na tsawon mintuna 2 ~ 3, sannan a ƙara 4/5 na ruwan da aka auna da farko, a motsa na tsawon mintuna 2 ~ 3, sannan a tantance sauran 1/5 na ruwan gwargwadon dankowar laka. . Bayan an gama haɗuwa sosai, ana yin gwajin gwaji, kuma ana ƙayyade adadin ruwan da aka ƙara a hade tare da yanayin rawar jiki da slurry. Bayan an ƙayyade adadin ruwan da aka ƙara, dole ne a sarrafa shi sosai. Duk da yake tabbatar da cewa slurry za a iya jijjiga, da ɗan ƙaramin ruwa kamar yadda zai yiwu ya kamata a ƙara (yawan adadin ruwa na wannan simintin shine 5.5% -6.2%).

4. Gina
Lokacin ginin babban simintin ƙaramar siminti-aluminum kusan mintuna 30 ne. Ba za a iya haɗa kayan da aka bushe ko naƙasa da ruwa ba kuma a jefar da su. Yi amfani da sandar girgiza don girgiza don cimma slurry compaction. Ya kamata a kiyaye sandar jijjiga don hana abin kunnawa lokacin da sandar girgiza ta gaza.
Ya kamata a yi aikin simintin gyare-gyaren a cikin ɗigon ramuka tare da axis na kiln rotary. Kafin kowace tsiri zuba, ya kamata a tsaftace filin ginin kuma kada a bar ƙura, walda da sauran tarkace. A lokaci guda, duba ko walda na anka da saman kwalta jiyya na fenti suna wurin. In ba haka ba, ya kamata a dauki matakan gyara.
A cikin ginin tsiri, ya kamata a zubar da ginin jikin tsiri a fili daga wutsiya zuwa kan kiln a kasan jikin kiln. Ya kamata a gudanar da goyan bayan samfurin tsakanin anka da farantin karfe. An ɗora farantin karfe da anga da ƙarfi tare da tubalan katako. Tsawon tsarin aikin tallafi shine 220mm, nisa shine 620mm, tsayin shine 4-5m, kusurwar tsakiya shine 22.5 °.
Ya kamata a gudanar da ginin jikin simintin gyare-gyare na biyu bayan an saita tsiri a ƙarshe kuma an cire nau'in. A gefe ɗaya, ana amfani da samfuri mai siffar baka don rufe simintin gyare-gyare daga kan kiln zuwa wutsiya na kiln. Sauran kwatankwacinsu ne.
Lokacin da aka jijjiga kayan simintin, ya kamata a ƙara gaurayen laka cikin ƙirar taya yayin girgiza. Ya kamata a sarrafa lokacin girgiza don kada a sami kumfa a zahiri a saman jikin simintin. Ya kamata a ƙayyade lokacin rushewa ta yanayin yanayin wurin ginin. Wajibi ne a tabbatar da cewa an aiwatar da ƙaddamarwa bayan an saita kayan simintin a ƙarshe kuma yana da wani ƙarfi.

5. Yin burodin rufi
Ingancin yin burodi na rufin kiln rotary kai tsaye yana shafar rayuwar sabis na rufin. A cikin tsarin yin burodin da ya gabata, saboda rashin ƙwarewar balagagge da hanyoyi masu kyau, an yi amfani da hanyar allurar mai mai nauyi don konewa a cikin ƙananan zafin jiki, matsakaici da zafi mai zafi. Yanayin zafin jiki yana da wuyar sarrafawa: lokacin da zafin jiki yana buƙatar sarrafawa a ƙasa da 150 ℃, mai mai nauyi ba shi da sauƙin ƙonewa; lokacin da zafin jiki ya fi 150 ℃, saurin dumama yana da sauri sosai, kuma yawan zafin jiki a cikin kiln yana da rashin daidaituwa. Zazzabi na rufin da aka ƙone mai mai nauyi yana da kusan 350 ~ 500 ℃ mafi girma, yayin da yawan zafin jiki na sauran sassa ya ragu. Ta wannan hanyar, rufin yana da sauƙin fashe (rufin simintin da aka yi a baya ya fashe yayin aikin yin burodi), yana shafar rayuwar sabis na rufin.
