Litene tse phahameng tsa Alumina Refractory: Balebeli ba Tšepahalang ba Liindasteri tsa Mocheso o Phahameng

Lefapheng la liindasteri tse nang le mocheso o phahameng, ts'ebetso ea thepa e khetholla ka ho toba botsitso le katleho ea tlhahiso.Litene tse phahameng tsa alumina refractory, joalo ka thepa ea boleng bo holimo e entsoeng haholo ka bauxite ea aluminium e phahameng, e fetohile khetho e nepahetseng bakeng sa liindasteri tse ngata tse nang le mocheso o phahameng ka ts'ebetso ea tsona e ntle, ho sireletsa nts'etsopele ea tšepe ea lefats'e, thepa ea kaho, lik'hemik'hale le liindasteri tse ling.

Melemo ea mantlha ea litene tse phahameng tsa alumina refractory e tsoa ho sebopeho sa tsona se ikhethang le ts'ebetso ea tlhahiso. Litene tsena li entsoe ka aluminium e phahameng ea bauxite clinker e nang le alumina content e seng ka tlase ho 48% e le kakaretso, e kopantsoe le li-binders ka likarolo tse fapaneng, ebe li thehoa, li omisitsoe, 'me li chesoa ka mocheso o phahameng. Litene tse phahameng tsa alumina refractoriness li na le refractoriness e babatsehang, tse khonang ho mamella mocheso o phahameng ho tloha 1770 ° C ho ea 1790 ° C. Esita le libakeng tse feteletseng tsa mocheso o phahameng, ba ka boloka botšepehi ba mohaho, ba hanyetsa ka katleho ho senyeha ha mocheso o phahameng ho thepa. Mocheso oa bona o motle oa ho nolofatsa moroalo o tiisa hore ha ba na tšekamelo ea ho senyeha le ho oa tlas'a khatello e itseng le mocheso o phahameng, ho fana ka litiiso tse ka tšeptjoang bakeng sa ts'ebetso e tsitsitseng ea thepa e phahameng ea mocheso. Ho phaella moo, litene tse phahameng tsa alumina refractory li na le ts'oaetso e ntle ea mocheso oa mocheso, e leng se ba lumellang ho boloka ts'ebetso e tsitsitseng nakong ea liphetoho tsa mocheso khafetsa, ho fokotsa ho phunyeha le ho phatloha ho bakoang ke khatello ea mocheso le ho lelefatsa bophelo ba bona ba tšebeletso. Li boetse li na le khanyetso e matla ea lik'hemik'hale tse sa tšoaneng. Ebang ke slag tšebetsong ea metallurgical kapa likhase tse senyang tlhahisong ea lik'hemik'hale, ho thata ho baka tšenyo e tebileng ho tsona.

Litene tse phahameng tsa alumina refractory li na le mefuta e mengata ea likopo. Indastering ea metallurgic, ke lisebelisoa tsa bohlokoa bakeng sa masela a libopi tsa ho etsa litšepe, libopi tsa ho etsa tšepe le libōpi tse futhumatsang. Ba ka khona ho hanela khoholeho ea tšepe e entsoeng ka mocheso o phahameng oa mocheso le slag, ho netefatsa tsoelo-pele e ntle ea ts'ebetso ea ho qhibiliha le ho ntlafatsa bophelo ba tšebeletso ea lisebelisoa le katleho ea tlhahiso. Indastering ea thepa ea moaho, litene tse phahameng tsa alumina refractory hangata li sebelisoa lisebelisoa tse kang libono tsa rotary tsa samente le libopi tse qhibilihang tsa khalase. Libakeng tse nang le mocheso o phahameng, ho phunyeha ha moea ka lebelo le phahameng, le ho senyeha ha thepa, ba ntse ba ka boloka ts'ebetso e ntle, ba tšehetsa ts'ebetso e tsitsitseng ea tlhahiso ea thepa ea mohaho. Indastering ea lik'hemik'hale, litene tse phahameng tsa alumina refractory li phetha karolo ea bohlokoa libonong tsa mocheso o phahameng oa mocheso le likhase. Ka matla a bona a ho hanyetsa ho bola ha lik'hemik'hale, ba netefatsa polokeho le katleho ea ts'ebetso ea tlhahiso ea lik'hemik'hale

Re na le lisebelisoa tse tsoetseng pele tsa tlhahiso le mokhoa o thata oa ho laola boleng. Sehokelo se seng le se seng, ho tloha ho theko ea thepa e tala ho isa ho phepelo ea sehlahisoa se felileng, se shejoa ka hloko. Ka ho amohela mekhoa e etellang pele ea tlhahiso ea machaba, re etsa bonnete ba hore boleng ba litene tse phahameng tsa alumina refractory li finyella litekanyetso tsa machaba. Ka nako e ts'oanang, re fana ka ts'ehetso ea botekgeniki ea litsebi le lits'ebeletso tse felletseng tsa kamora thekiso. Ho latela litlhoko tse fapaneng tsa bareki, re fana ka tharollo ea motho ka mong ho netefatsa hore litene tse phahameng tsa alumina refractory li ka sebetsa hantle lits'ebetsong tse sebetsang.

Ho khetha litene tsa rona tse phahameng tsa alumina refractory ho bolela ho khetha boleng le ho tšepahala. Hore na o hloka phumants'o e kholo kapa litharollo tsa lisebelisoa tsa profeshenale, re ka fihlela litlhoko tsa hau. Re amohela ka mofuthu bareki ba tsoang lefats'eng lohle ho ikopanya le rona le ho sebetsa 'moho ho theha bokamoso bo khanyang bakeng sa indasteri ea mocheso o phahameng!
