Hanyar ginawa ta amfani da ƙaramin siminti mai ƙarfi na aluminum don rufin murhun juyawa
Gina siminti mai ƙarancin aluminum mai ƙarfi wanda za a iya amfani da shi don rufin murhun rotary yana buƙatar kulawa ta musamman ga waɗannan matakai guda biyar:

1. Tantance hanyoyin faɗaɗawa
Dangane da gogewar da aka samu a baya na amfani da manyan ƙarfe masu ƙarancin siminti na aluminum, haɗin gwiwa na faɗaɗawa muhimmin abu ne da ke shafar tsawon rayuwar layukan da za a iya amfani da su wajen yin ...

(1) Haɗaɗɗun da'ira: Sassan mita 5, jifa mai siliki na aluminum 20mm an haɗa su tsakanin kayan da aka yi amfani da su, kuma ana matse zare bayan faɗaɗawa don rage matsin lamba na faɗaɗawa.

(2) Haɗaɗɗun layuka uku: Kowace tsiri uku na abin da aka yi da siminti an yi masa ado da katako mai zurfin mm 100 a cikin alkiblar da'irar ciki, sannan a bar haɗin gwiwa a ƙarshen aiki, wanda ya kai jimillar tsiri 6.

(3) A lokacin zubawa, ana amfani da fil 25 na shaye-shaye a kowace murabba'in mita don fitar da wani adadin matsin lamba na faɗaɗa yayin da ake shanye murhun.

2. Tabbatar da zafin jiki na gini
Zafin da ya dace na siminti mai ƙarancin siminti mai yawan aluminum shine 10 ~ 30℃. Idan zafin yanayi ya yi ƙasa, ya kamata a ɗauki waɗannan matakan:

(1) Rufe yanayin gini da ke kewaye, ƙara kayan dumama, kuma a hana daskarewa sosai.

(2) Yi amfani da ruwan zafi a zafin 35-50℃ (wanda aka ƙaddara ta hanyar girgizar gwajin zubar da ruwa a wurin) don haɗa kayan.

3. Hadawa
A tantance adadin gaurayawan a lokaci guda bisa ga ƙarfin mahaɗin. Bayan an ƙayyade adadin gaurayawan, a ƙara kayan jifa a cikin jakar da ƙananan ƙarin kayan da ke cikin jakar a cikin mahaɗin a lokaci guda. Da farko a fara mahaɗin don busar da shi na tsawon minti 2-3, sannan a ƙara 4/5 na ruwan da aka auna da farko, a juya na tsawon minti 2-3, sannan a tantance sauran 1/5 na ruwan gwargwadon ɗanɗanon laka. Bayan an haɗa gaba ɗaya, ana gwada zuba ruwa, kuma ana tantance adadin ruwan da aka ƙara tare da yanayin girgiza da slurry. Bayan an ƙayyade adadin ruwan da aka ƙara, dole ne a sarrafa shi sosai. Yayin da ake tabbatar da cewa slurry ɗin zai iya girgiza, ya kamata a ƙara ɗan ruwa gwargwadon iko (adadin ƙarin ruwa na wannan castable shine 5.5%-6.2%).

4. Gine-gine
Lokacin ginawa na siminti mai ƙarancin aluminum mai ƙarfi yana ɗaukar kimanin minti 30. Ba za a iya haɗa kayan da aka busar da ruwa ko aka taƙaice da ruwa ba kuma ya kamata a jefar da su. Yi amfani da sanda mai girgiza don girgiza don cimma matsewar slurry. Ya kamata a ajiye sandar girgiza don hana sandar da aka taƙaice kunnawa lokacin da sandar girgiza ta gaza.
Ya kamata a yi aikin gina kayan da za a iya yin siminti a cikin layukan da ke kan murhun juyawa. Kafin a zuba kowane tsiri, ya kamata a tsaftace saman ginin kuma kada a bar ƙura, tarkacen walda da sauran tarkace. A lokaci guda, a duba ko walda na anga da kuma maganin fenti na kwalta a saman suna nan. In ba haka ba, ya kamata a ɗauki matakan gyara.
A cikin ginin tsiri, ya kamata a zubar da ginin simintin tsiri a fili daga wutsiyar murhu zuwa kan murhu a ƙasan jikin murhu. Ya kamata a yi amfani da goyon bayan samfurin tsakanin anga da farantin ƙarfe. An lulluɓe farantin ƙarfe da anga da tubalan katako sosai. Tsawon tsarin tallafi shine 220mm, faɗin shine 620mm, tsawon shine 4-5m, kuma kusurwar tsakiya shine 22.5°.
Ya kamata a yi ginin jikin siminti na biyu bayan an gama saita tsiri kuma an cire mold ɗin. A gefe ɗaya, ana amfani da samfurin siffar baka don rufe simintin daga kan murhu zuwa wutsiyar murhu. Sauran kuma iri ɗaya ne.
Idan kayan jifa suka yi rawar jiki, ya kamata a ƙara laka mai gauraya a cikin tsarin tayar yayin da take rawar jiki. Ya kamata a sarrafa lokacin girgiza don kada a sami kumfa a saman jikin jifa. Ya kamata a ƙayyade lokacin jifa ta hanyar zafin wurin ginin. Ya kamata a tabbatar da cewa an yi jifa bayan an saita kayan jifa kuma yana da wani ƙarfi.

5. Yin burodin rufi
Ingancin yin burodi na layin murhun juyawa yana shafar rayuwar rufin kai tsaye. A cikin tsarin yin burodi na baya, saboda rashin ƙwarewa mai kyau da kuma hanyoyi masu kyau, an yi amfani da hanyar allurar mai mai nauyi don ƙonewa a cikin tsarin yin burodi na ƙarancin zafi, matsakaicin zafin jiki da kuma babban zafin jiki. Yanayin zafin ya kasance da wuya a sarrafa shi: lokacin da zafin jiki ke buƙatar a sarrafa shi ƙasa da 150℃, mai mai nauyi ba shi da sauƙin ƙonewa; lokacin da zafin ya fi 150℃, saurin dumama yana da sauri sosai, kuma rarraba zafin jiki a cikin murhun ba shi da daidaito sosai. Zafin rufin inda aka ƙone mai mai nauyi yana da kusan 350 ~ 500℃ sama, yayin da zafin sauran sassa yake ƙasa. Ta wannan hanyar, rufin yana da sauƙin fashewa (layin da aka riga aka jefa ya fashe yayin aikin yin burodi), yana shafar rayuwar rufin.
