Roller ea Ceramic ea Alumina
Lirolo tsa letsopa tsa Aluminake dihlahiswa tsa letsopa tsa indasteri tse sebetsang hantle haholo tse entsweng haholo-holo ka alumina (Al₂O₃), mme ke dikarolo tsa bohlokwa tsa di-roller kilns tsa sejwalejwale tse nang le mocheso o phahameng. Di entswe ka alumina e hlwekileng haholo ka ho tobetsa ka isostatic le ho sintering ka mocheso o phahameng, rolara ya rona e ikgantsha ka ho hanyetsa mocheso o phahameng haholo, ho hanyetsa ho tsofala le botsitso ba ho tshoha ha mocheso. Re fana ka tlhophiso e felletseng ho fihlela ditlhoko tsa motho ka mong tsa diindasteri le disebediswa tse fapaneng.
Litlhaloso tse Tloaelehileng le ho Itlhophisa:
Litlhaloso tse tloaelehileng li ka tlase; ho iketsetsa ka botlalo ho fumaneha ho latela liparamente tsa hau, litšoantšo kapa litlhoko tsa onto/tlhahiso:

2. Bophara ba Kantle:12–100mm (e tloaelehileng 12-80mm, e ka fetoloang 10–150mm, e ka fetoloang ho mamellana)
3. Bolelele:500–6000mm (e tloaelehileng ea 1200-5300mm, e ka fetoloang ea 300–6000mm, ho kopanya ho telele hoa fumaneha)
4. Ho Monya Metsi:3–6% (e ka fetoloang ≤2% kapa litlhoko tse khethehileng)
5. Matla a ho Kobeha:60–100MPa (e ka fetoloa ho fihlela ho 150MPa)
6. Mofuta:E tiileng/E nang le sekoti (e ka fetoloang ka ho feletseng: botenya ba lebota/lesoba le ka hare)
7. Mekhoa e meng ea ho iketsetsa lintho:Kalafo ea bokaholimo, sebopeho sa qetello, karolelano e khethehileng ea thepa bakeng sa maemo a feteletseng.
Likarolo tsa Sehlahisoa:
1. Khanyetso e Hlollang ea Mocheso o Phahameng:Mocheso o phahameng ka ho fetisisa oa ts'ebetso ho fihlela ho 1600℃, ho hanyetsa mocheso ≥1750℃, ho tsitsisa mochesong o phahameng ntle le ho fetoha; botsitso ba mocheso bo tšepahalang haholo le ho hanyetsa ho ts'oaroa ha mocheso hantle bakeng sa lihlahisoa tse thunngoeng ho fihlela ho 1400℃.
2. Ho tiea le ho Hloahala ho Hoholo:Thatafalo ea Rockwell HRA80-90 (ea bobeli ho feta daemane), thatafalo ea Mohs ≥9; khanyetso ea ho tsofala e makhetlo a 266 ho feta tšepe ea manganese le makhetlo a 171.5 ho feta tšepe e nang le chromium e ngata, e leng se eketsang bophelo ba lisebelisoa bonyane ka makhetlo a leshome le ho fokotsa nako ea ho se sebetse le litšenyehelo.
3. Botsitso bo Phahameng ba ho Tšoha ha Thermal:Katoloso e tlase ea mocheso, e hanela ho futhumatsoa/ho pholisoa ka potlako, ha ho bonolo ho e petsoha.
4. Botsitso bo Botle ba Lik'hemik'hale:E hanela mafome ka asiti/alkali/glaze, ha e na tšilafalo ho dihlahiswa tse sebetswang.
5. Bokaholimo bo Boreleli le ho Nepahala ho Holimo:E silafalitsoe ka nepo (Ra ≤1.6μm), ts'ebetso e tsitsitseng, ha ho na mengoapo (ho nepahala ho ka fetoloa).
6. Leseli le ho Boloka Matla:Botenya ba 3.5–3.8 g/cm³ (3.6 g/cm³ joalo ka tloaelo, halofo feela ea tšepe), e fokotsa mojaro oa lisebelisoa haholo le ho lelefatsa bophelo ba lisebelisoa.
