T38 leben alumina sare ah (nooca mindi)

T38, t39 lebenkii alumina sare waa qaybaha ugu waaweyn ee bauxite alumina sare; macdanta kooxda sillimanite (oo ay ku jiraan kyanite, andalusite, sillimanite, iwm); alaabta ceyriinka ah ee dardaaranka ah, sida alumina warshadeed, mullite synthetic, korontada corundum Fused iyo wixii la mid ah. Bani’aadamka alumina banadium ee hodanka ah wuxuu hodan ku yahay kheyraad iyo qaab dhismeed aad u fiican. Aagagga wax -soo -saarka ayaa inta badan lagu qaybiyaa Shanxi, Henan, Hebei, Guizhou, Shandong iyo meelo kale. Bauxite alumina sare leh oo la soo saaray badiyaa waa isku dar ah bauxite (α-Al2O3 · H2O) iyo kaolinite.

Leben alumina sare waa qalab dhexdhexaad ah oo dhexdhexaad ah oo ka kooban alumina oo aan ka yarayn 60%. Waxaa la sameeyay oo laga soo duubay bauxite ama alaab kale oo cayriin leh oo leh alumina sare. Warshadeena waxay soo saartaa leben alumina sare leh oo leh xasilooni sare iyo ku -tiirsanaan ka sarreysa 1700 ℃. Iska caabbinta dhoobada wanaagsan waxaa inta badan loo adeegsadaa dahaarka foornooyinka qarxa, foornooyinka qarxa kulul, saqafyada foornada korontada, foornooyinka qarxa, foornooyinka reverberatory, iyo shoolada Rotary. Badeecadaha ugu waaweyn ee warshaddeennu waa lebenkii guud ee alumina-sare (ie, lebenkii T-madaxa) T-3 T38 T39 T19 T20 T23 T7 T52, lebenkii-alumina-sare ee qaaska ahaa, lebenkii jaban ee foornada jaban G1 G2 G3 G4 G5 G6 GXNUMX lebenkii geeska qaansada iyo lebenkii kale ee jaban oo tayo sare leh.

1. Refractoriness: The refractoriness of t38 and t39 high alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which belong to advanced refractory materials.

2. Heerkulka jilicsanaanta culayska: Sababtoo ah alaabada aluminiumka sare leh waxay leeyihiin Al2O3 sare, wasakh yari, iyo galaas yar oo la suuxin karo, heerkulka jilicsanaanta culeysku wuxuu ka sarreeyaa lebenkii dhoobada iyo lebenkii alumina sare, laakiin maxaa yeelay kiristaalo mullite ma samaysmaan qaab dhismeed shabakad, Heerkulka jilicsan culayska saaran weli ma sarreeyo kan lebenka silica ah.

3. Iska caabin slag: lebenkii alumina sare wuxuu ka kooban yahay Al2O3 ka badan, kaas oo u dhow agab -diidmo dhexdhexaad ah, wuxuuna iska caabin karaa nabaad -guurka aashitada asiidhka ah iyo diirka alkaline. Maaddaama ay ka kooban tahay SiO2, kartida iska -caabbinta wasakhda alkaline -ka ayaa ka fiican tan dhagaxa aashitada ah. Daciif ah. Habka wax soo saarka ee lebenka alumina ee sarreeya iyo lebenka dhoobada badan leh ayaa la mid ah. Farqiga ayaa ah in saamiga clinker ee maaddooyinka uu ka sarreeyo, kaasoo noqon kara 90-95%. Klinkerku wuxuu u baahan yahay in la kala sooco oo la shaandheeyo si birta looga saaro ka hor intaan la jajabin, iyo heerkulka dabka Sare, sida Ⅰ, b lebenka alumina ee sare ah guud ahaan waa 1500 ~ 1600 ℃ marka lagu dhex tuuro godka tunnelka. Ku-dhaqanka wax-soo-saarka Shiinaha ayaa caddeeyay in ka hor intaan la burburin, clinker-alumina-ka sare ayaa si adag loo xushay oo loo kala saaray, loona kaydiyey heerar. Isticmaalka clinker bauxite iyo dhoobada isku dhafan ee habka shiidi kara ayaa hagaajin kara tayada badeecada. Badanaa waxaa loo adeegsadaa dhisidda foornooyinka qaraxa, foornooyinka qarxa kulul, iyo saqafyada foornada korontada. , Foornada qaraxday, foornada dhawaaqa, dahaarka weelka rooga, iwm.

Leben-celis sare-alumina, oo ah, aluminium silicate aluminium ah oo ka kooban alumina ka badan 48%. Waxaa la sameeyay oo laga soo duubay bauxite ama alaab kale oo cayriin leh oo leh alumina sare. Xasiloonida kuleylka sare, dib -u -kicinta ka sarreysa 1770 ℃. Iska caabbinta dhoobada ayaa ka fiican.

Caadi ahaan waxaa loo qaybiyaa afar qaybood:

Fasalka I: Maadada Al2O3 ≥75%;

Fasalka Ⅱ: Al2O3 waxa ku jira 60%~ 75%;

Fasalka Ⅲ: waxa ku jira Al2O3 waa 48%~ 60%;

Fasal gaar ah: content AL2O3 ≥80%.

Waxa kale oo lagu kala saari karaa hadba macdanta macdanta, guud ahaan waxay u qaybsantaa shan qaybood: mullite hoose (sillimanite), mullite, mullite-corundum, corundum-mullite iyo corundum.
