1. Tšireletso ea Thermocouple: Tlhokomelo e Nepahetseng ea Mocheso Maemong a Mabe
Taolo ea mocheso ke ea bohlokoa bakeng sa boleng le polokeho ea indasteri, 'me li-thermocouple ke lisebelisoa tsa mantlha tsa ho lekanya mocheso. Leha ho le joalo, liontong tsa mocheso o phahameng, li-smelting tsa tšepe tse se nang tšepe, le lisebelisoa tsa kalafo ea mocheso, li-thermocouple tse sa sirelelitsoeng li senyeha habonolo ke oxidation, mafome, kapa khoholeho ea tšepe e qhibilihisitsoeng - e leng se lebisang ho lipalo tse sa nepahalang, nako e sa reroang ea ho sebetsa, le litšenyehelo tse phahameng tsa tlhokomelo.Li-tube tsa tšireletso tsa NBSiC li entsoe ho sireletsa li-thermocouple, e leng se etsang hore e be khetho e holimo bakeng sa maemo a ho beha leihlo mocheso o feteletseng.
Coefficient ea tsona ea katoloso e tlase ea mocheso (4.4×10⁻⁶/℃) le masoba a tlase (<1%) li netefatsa botsitso ba boholo le ho thibela mafome a bakoang ke likhase tse nang le asiti/alkaline le litšepe tse qhibilihisitsoeng. Ka boima ba Mohs ~9, li hanela ho tsofala ha lintho tse nyenyane.Mesebetsi ea bohlokoa e kenyelletsa lifono tsa tšepe, lifono tsa aluminium tse qhibilihang, le lifono tsa ceramic, moo li-tubes tsa NBSiC li atolosang bophelo ba thermocouple ka makhetlo a 3 kapa ho feta ha li bapisoa le mekhoa e meng ea setso.
2. Ho Qhibilihisa le ho Lahla Tšepe e sa Fereng: Tšireletso ea Ts'ebetso ea Bohlokoa
Liindasteri tsa ho qhibilihisa/ho lahla aluminium, koporo le zinki li tobane le liphephetso tse kholo: khoholeho ea tšepe e qhibilihisitsoeng le likotsi tsa tšilafalo.Li-tube tsa tšireletso tsa NBSiC li phetha mesebetsi e 'meli ea bohlokoa mona, li fana ka litharollo tse etselitsoeng uena.
a. Liphaephe tse Koaletsoeng bakeng sa Tšireletso ea Lintho tse Futhumatsang
Liforong tsa aluminium tse qhibilihang, likarolo tsa ho futhumatsa tsa silicon carbide lia hlokahala empa li kotsing ea ho khoholeha ha aluminium e qhibilihisitsoeng.Liphaephe tsa NBSiC tse koetsoeng li sebetsa e le tšitiso, li arola likarolo tsa ho futhumatsa ho tsoa tšepeng e qhibilihisitsoeng ho lelefatsa nako ea tsona ea bophelo le ho qoba tšilafalo.Ho tsamaisa mocheso ha tsona ho phahameng ho netefatsa phetiso e sebetsang hantle ea mocheso, ho fokotsa tšebeliso ea matla. Li ka fetoloa ka bophara (ho fihlela ho 600mm) le bolelele (ho fihlela ho 3000mm), li ikamahanya le meralo e fapaneng ea setofo.
b. Li-Riser bakeng sa ho Lahla Mabili a Aluminium
Li-risers tsa NBSiC tse bulehileng (li-tube tse phahamisang) li nolofalletsa phallo ea aluminium e qhibilihisitsoeng ho tloha liontong ho ea ho li-form tsa ho lahla tlhahiso ea mabili a aluminium. Ka modulus e batang ea ho phatloha >150MPa le khanyetso e ntle ea mocheso oa ho phatloha (ho sa tsotelehe lipotoloho tse 100 tsa mocheso oa kamore oa 1000℃), li netefatsa phallo e tsitsitseng, e tsoelang pele - e fokotsa liphoso tsa ho lahla (li-porosity, li-inclusions) le ho ntlafatsa chai. Ho fapana le li-tube tsa tšepe e qhibilihisitsoeng, NBSiC ha e silafatse aluminium e qhibilihisitsoeng, e boloka bohloeki ba sehlahisoa.
3. Ditshebediso tsa Dikhemikhale le Setofo: Khanyetso ya Tshenyo Ditikolohong tse Matla
Litsi tsa ho sebetsana le lik'hemik'hale (petso ea peterole, tlhahiso ea asiti/alkali) le li-kiln tsa ceramic/khalase li sebetsa ka likhase tse matla le mocheso o phahameng.Li-tube tsa NBSiC li sireletsa li-sensor le likarolo tsa ho futhumatsa mona, ka lebaka la ho hanyetsa mafome ka kakaretso.Li-reactor tse petsohang peterole, li hanela ho bola ha H₂S le CO₂ mochesong o phahameng; li-kiln tsa ceramic/glass, li sireletsa li-thermocouple ho tloha sepakapakeng sa oxidative le ho tsofala, e leng se netefatsang taolo e nepahetseng ea mocheso bakeng sa lihlahisoa tsa boleng.
Li-tube tsa tšireletso tsa NBSiC li kopanya ho boloka litšenyehelo hantle le ts'ebetso e sa sekisetseng, li fana ka bophelo bo bolelele ba ts'ebeletso, tšireletso ea lisebelisoa tsa bohlokoa, le ho iketsetsa lintho ka tsela e ikhethileng. Ebang ke tsa tšepe, kalafo ea mocheso, lik'hemik'hale, kapa matla a macha, li fana ka ts'epo e hlokahalang ho lula li qothisana lehlokoa.Ikopanye le rona kajeno ho hlahloba ditharollo tse ikgethileng bakeng sa diphephetso tsa hao tsa mocheso o phahameng le mafome.
