Anti-spalling High Alumina Bricks Bakeng sa Cement Rotary Kiln

Ts'ebetso ea sehlahisoa:E na le botsitso bo matla ba mocheso o phahameng oa mocheso, khanyetso e ntle ea mocheso oa mocheso, khanyetso ea ho roala, khanyetso ea kutu ea lik'hemik'hale le litšobotsi tse ling.

Lisebelisoa tse kholo:Haholo-holo e sebelisoa libakeng tsa phetoho tsa libopi tsa rotary tsa samente, libopi tsa ho bola, likotopo tsa moea o phahameng, le lisebelisoa tse ling tsa mocheso tse hlokang ho hanyetsa mocheso oa mocheso.

Likarolo tsa sehlahisoa:E le thepa ea motheo ea indasteri ea refractory, litene tse phahameng tsa alumina li na le litšobotsi tsa ho hanyetsa ka mokhoa o phahameng, mocheso o batlang o le boima o fokolang (hoo e ka bang 1500 ° C), le ho hanyetsa khoholeho e ntle. Li sebelisoa haholo ho li-kilns tsa indasteri liindastering tse fapaneng. Leha ho le joalo, , ka lebaka la likarolo tse phahameng tsa karolo ea corundum ea litene tse tloaelehileng tse phahameng tsa alumina, likristale tsa karolo ea corundum lihlahisoa tse sintered li kholoanyane, 'me ho phunyeha le ho senya ho tloaelehile ho etsahala ha ho kopana le maemo a pholileng a potlakileng le a futhumatsang. Thermal shock stability tlas'a 1100 ° C maemo a ho pholisa metsi ke feela E ka fihla makhetlo a 2-4. Sistimi ea tlhahiso ea samente, ka lebaka la likhaello tsa mocheso oa mocheso le litlhoko tsa ts'ebetso bakeng sa lisebelisoa tsa refractory ho khomarela letlalo la sebōpi, litene tse phahameng tsa alumina li ka sebelisoa feela sebakeng sa phetoho ea sebōpi sa rotary, mohatla oa kiln le preheater ea sebōpi sa ho bola. .

Litene tse phahameng tsa aluminium tse khahlanong le spalling li na le litene tse phahameng tsa aluminium tse nang le thepa ea anti-flaking e hlahisoang ho latela clinker e phahameng ea aluminium 'me e eketsoa ka ZrO2 kapa lisebelisoa tse ling. Li ka aroloa ka mekhahlelo e 'meli, e' ngoe ke litene tsa alumina tse khahlanong le flaking tse nang le ZrO2, 'me e' ngoe ke Mofuta oa pele ke setene sa alumina se phahameng sa anti-flaking se se nang ZrO2.

Litene tsa aluminium tse khahlanong le spalling tse phahameng li ka hanela mocheso o phahameng oa mocheso, ha li fokotsehe ka molumo le ho ba le katoloso e ts'oanang, ha li thekesele kapa li oa, li na le matla a phahameng a mocheso a tloaelehileng le matla a mocheso a phahameng a mocheso, mocheso o phahameng oa ho nolofatsa mojaro, le e na le ho hanyetsa mocheso o motle. E khona ho mamella tšusumetso ea liphetoho tsa tšohanyetso tsa mocheso kapa mocheso o sa lekaneng, 'me e ke ke ea peperana kapa ea ebola. Phapang lipakeng tsa litene tse phahameng tsa alumina tse anti-flaking tse nang le ZrO2 le litene tse phahameng tsa alumina tse khahlanong le flaking ntle le ZrO2 li teng mekhoeng ea tsona e fapaneng ea anti-flaking. Litene tse phahameng tsa alumina tse nang le li-anti-flaking tse nang le ZrO2 li sebelisa lisebelisoa tsa zircon ho etsa ts'ebeliso e ntle ea ho hanyetsa kutu. ZrO2 e hanela khoholeho ea sebabole-chlor-alkali. Ka nako e ts'oanang, ka mocheso o phahameng, SiO2 e nang le zircon e tla ba le phetoho ea karolo ea kristale ho tloha cristobalite ho ea karolong ea quartz, e leng se etsang hore ho be le phello e itseng ea ho atolosa molumo, kahoo ho fokotsa kotsi ea ho thibela sebabole-chlor-alkali. Ka nako e ts'oanang, e thibela ho phatloha nakong ea ts'ebetso e chesang le e batang; anti-flaking high alumina litene tse se nang ZrO2 li hlahisoa ka ho eketsa andalusite ho litene tse phahameng tsa alumina. Andalusite sehlahiswa e sebediswa bakeng sa mulliteization bobeli ka sebōping samente. E hlahisa phello e ke keng ea qojoa ea micro-expansion e le hore sehlahisoa se se ke sa fokotseha ha se pholile, sa felisa khatello ea kelello ea ho fokotseha le ho thibela ho peeling ea sebopeho.

Ha ho bapisoa le litene tse nang le li-alumina tse nang le li-anti-spalling tse se nang ZrO2, litene tse khahlanong le spalling tse phahameng tsa alumina tse nang le ZrO2 li na le khanyetso e ntle ea ho kenella le ho senyeha ha sebabole, chlorine le likarolo tsa alkali, kahoo li na le thepa e ntle ea anti-flaking. Leha ho le joalo, hobane ZrO2 ke thepa e sa tloaelehang, e theko e boima, kahoo litšenyehelo le theko li phahame.Litene tsa aluminium tse nang le li-anti-flaking tse nang le ZrO2 li sebelisoa feela sebakeng sa phetoho ea libotlolo tsa rotary tsa samente. Litene tse nang le aluminium tse nang le li-anti-flaking tse se nang ZrO2 li sebelisoa haholo liboping tsa ho bola tsa mela ea tlhahiso ea samente.
