Ntho e qhibilihang ke efe litene refractory?

Litene tse refractory ke lisebelisoa tse thibelang mocheso, tse sebelisoang haholo ts’ebetsong ea mocheso o phahameng joalo ka lichimney le li-kilns. Leha ho le joalo, litene tse refractory le tsona li na le lintlha tse qhibilihang. Mefuta ea thepa ea litene tse refractory e fapane. Khetha mofuta oa litene tse refractory ho latela ts’ebeliso ea hau ea mosebetsi.

Refractory e entsoeng ka letsopa le sa cheng kapa lintho tse ling tse refractory. Haholo-holo e sebelisetsoang ho haha ​​sebōpi sa ho qhibilihisa, e ka mamella mocheso o phahameng oa 1,580 ℃-1,770 ℃;

litene tsa letsopa ke tse fokolang acidic refractory thepa. Hang ha refractoriness ea litene tsa letsopa tse sebelisoang libōping tsa indasteri li ka holimo ho 1600 ° C, mocheso oa ho qala oa ho nolofatsa mojaro ke 1250-1300 ° C feela. Litene tsa letsopa tse sebelisoang ke liindasteri tsa Yiran li ruile haholo ka thepa e tala, theknoloji ea tlhahiso e batla e le bonolo, ‘me litšenyehelo li batla li le tlaase. Li sebelisoa haholo kahong ea libopi tse fapaneng tsa ho futhumatsa tsa Yiran le liphaephe, lichimney le lichimney tsa libopi tsa ho futhumatsa mocheso tsa Yiran. ‘Mele oa sebōpi, lisebelisoa tsa mocheso oa litšila le licheso tsa tsamaiso ea mollo, joalo-joalo.

Setene sa Magnesia ke thepa e hanyetsang e nang le MgO e ka holimo ho 80-85% le periclase e le setsi sa mantlha sa liminerale. Sebaka se qhibilihang sa MgO se holimo ho 2800 ℃. Refractoriness ea setene sa magnesia e ka holimo ho 2000 ℃, empa ntlha ea eona e bonolo tlas’a mojaro e tlaase haholo, ha feela 1500-1550 ℃. Lebaka ke hore likristale tsa periclase tse pota-potileng li kopantsoe ke forsterite e tlaase ea melting (CaO·MgO·SiO2) le khalase, ha periclase e sa thehe marang-rang a crystalline a tsoelang pele, mocheso oa deformation oa mojaro o tlaase haholo, ‘me qalong Mocheso oa mocheso ho tloha ho nolofatsa. ho 40% deformation e nyane haholo, ha feela 30-50 ℃. Ho tsitsisa ha mocheso oa litene tsa magnesia le hona ho futsanehile, ‘me ho phunyeha feela nakong ea ho pholile ka potlako le ho futhumatsa, e leng ntho ea bohlokoa ho senya litene tsa magnesia.

Litene tse akaretsang tsa corundum li loketse ho koahela holim’a mollo oa libopi tse boima tsa oli tse nang le khatello ea ho sebetsa ea 3MPa kapa ka tlaase ho moo, karolo ea bohlokoa ea lesela la metsi a litšila a letsoai, le litene tse chesang tse chesang tse sebetsang mocheso o phahameng. Ka kakaretso, mocheso oa tšebeliso ea litene tsa corundum o ka tlase ho 1600-1670 likhato tsa Celsius. Litene tsa letsopa tse bobebe tse bobebe li sebelisoa e le masela a sebōpi a sa jeoang ke mocheso o phahameng oa mocheso le likhase tse senyang. Ho itšetlehile ka bokhoni, mocheso oa ho sebetsa o pakeng tsa 1150-1400 likhato tsa Celsius

Ka holimo ke kakaretso ea lintlha tse fapaneng tsa ho qhibiliha ha litene tsa refractory ho latela mefuta e fapaneng. Ha u khetha litene tse refractory, u ka boela ua khetha se nepahetseng ho ea ka ntlha ea ho qhibiliha.
