Tlhaloso
Setene se phahameng sa alumina ke mofuta oa refractory, karolo e ka sehloohong ea eona e leng Al2O3. Haeba litaba tsa Al2O3 li phahame ho feta 90%, e bitsoa setene sa corundum. Ka lebaka la lisebelisoa tse fapaneng, litekanyetso tsa linaha tse fapaneng ha li lumellane ka ho feletseng. Ka mohlala, linaheng tsa Europe, moeli o ka tlaase oa Al2O3 bakeng sa li-refractories tse phahameng tsa alumina ke 42%. Chaena, litaba tsa Al2O3 ka setene se phahameng sa alumina hangata li arotsoe ka lihlopha tse tharo: Grade I - Al2O3 content> 75%; sehlopha sa II - litaba tsa Al2O3 ke 60-75%; grade III - Al2O3 content ke 48-60%.
Likaroloana:
1.High refractoriness
2.Matla a mocheso o phahameng
3.Botsitso bo phahameng ba mocheso
4.Refractory e sa nke lehlakore
5.Ho hanyetsa hantle ho acid le ho senyeha ha slag ea motheo
6.High refractoriness tlas'a mojaro
7.High mocheso creep khanyetso
8.Porosity e hlakileng e tlase
