Gaar ahaan aluminium sare lebenkii alwaax ahaanta ku shaqeeya

Qalabka refractory ee aluminosilicate ka mid ah, lebennada aluminiumka ah ee sarreeya ayaa leh dib-u-celin sare. Marka maaddada Al2O3 ee badeecaddu ay korodho, refractoriness ayaa kordha, guud ahaan aan ka yarayn 1750℃～1790℃. Marka waxa ku jira aluminiumku ka weyn yahay 95%, refractoriness waxay noqon kartaa ilaa 1900 ℃ – 2000 ℃.

Marka lagu daro SiO2 iyo oksaydhyada birta, heerkulka jilcinta culeyska ee lebennada aluminium ee sare ayaa hoos u dhacaya. Heerkulka jilcinta culeyska ee lebenka aluminiumka sare ee caadiga ah waa 1420℃～1530℃. Heerkulka jilcinta ee alaabta corundum ee ka kooban Al2O3 in ka badan 95% ayaa ka sarreeya 1600℃.

Lebenka refractory alumina sare waxay leeyihiin shaqada iska caabinta slags kala duwan. Sababtoo ah maaddada sare ee Al2O3 ee badeecada iyo dhexdhexaadnimadeeda, waxay leedahay iska caabin adag oo daxalka u leh aashitada iyo alkali slag.

Lebenka aluminiumka ah ee sarreeya waxay leeyihiin iska caabin shoog kulayl ah. Corundum iyo kiristaalo mullite waa wada nool yihiin, iyo isku xidhka fidinta tooska ah ee corundum ayaa ka weyn kan mullite. Sidaa darteed, marka heerkulku kor u kaco, kala duwanaanshaha balaadhinta badeecadu waxay keenaysaa xooga saarista walaaca. Sidaa darteed, iska caabbinta shoogga kuleylka ee lebenka aluminiumka sare waa mid liita, tirada qaboojinta biyaha waa 3 ilaa 5 jeer oo keliya.
