Imu nganda zikabije—zirangwa n’ubushyuhe bwinshi, imashini zica ibintu byangiza, n’isuri y’ibyuma bishongeshejwe—uburinzi bw’ibikoresho bwizewe ni ingenzi cyane kugira ngo umusaruro ukomeze kuba mwiza kandi ube mwiza.Imiyoboro yo kurinda ikoreshwa rya nitride bonded silicon carbide (NBSiC), ibikoresho bivanze bikozwe mu buryo bwo hejuru bigizwe na 70-80% bya silicon carbide (SiC) na 20-30% bya silicon nitride (Si₃N₄), birangwa n'imiterere idasanzwe: kurwanya ubushyuhe bwinshi kugeza kuri 1450℃ (1650-1750℃ mu kirere runaka), kurwanya ingese/abrasion nziza, kudahungabana kw'ubushyuhe, no gutwara ubushyuhe bwinshi.Dore uburyo bw'ingenzi bakoresha, bigaragaza uburyo bakemura ibibazo by'ingenzi ku nganda mpuzamahanga.
1. Uburinzi bwa Thermocouple: Gukurikirana neza ubushyuhe mu bihe bikomeye
Kugenzura ubushyuhe ni ingenzi ku bwiza n'umutekano by'inganda, kandi thermocouples ni zo zikoreshwa cyane mu gupima ubushyuhe. Ariko, mu itanura rishyuha cyane, mu byuma bishongesha ibyuma bidakoresha fer, no mu bikoresho bitunganya ubushyuhe, thermocouples zitarinzwe zangirika byoroshye kubera oxidation, ingese, cyangwa isuri y'icyuma cyashongeshejwe—bigatuma imiterere idahwitse, igihe kitateganijwe cyo kudakora neza, ndetse n'amafaranga menshi yo kubungabunga.Imiyoboro yo kurinda ya NBSiC yakozwe kugira ngo irinde thermocouples, bigatuma iba amahitamo meza mu gihe cyo kugenzura ubushyuhe bukabije.
Igipimo cyazo cyo kwaguka k'ubushyuhe buke (4.4 × 10⁻⁶/℃) n'umuvuduko muke (<1%) bitanga ubushobozi bwo kudahinduka kandi bikarinda ingese iterwa n'imyuka ikomoka kuri aside/alkali hamwe n'ibyuma bishongeshejwe. Kubera ko Mohs ikomeye ~9, zirinda kwangirika kw'ibintu bito.Ikoreshwa ry'ingenzi ririmo amatanura yo gukora ibyuma, amatanura ashongeshwa na aluminiyumu, n'amatanura ya keramike, aho imiyoboro ya NBSiC yongera igihe cyo kubaho cya thermocouple inshuro 3 cyangwa zirenga ugereranije n'andi mashya asanzwe.
2. Gushonga no Gucukura Ibyuma Bidakoresha Feri: Uburinzi bw'Ibikorwa by'ingenzi
Inganda zitunganya/zicukura aluminium, umuringa, na zinc zihura n'imbogamizi zikomeye: isuri ry'ibyuma bishongeshejwe n'ibyago byo kwanduza.Imiyoboro yo kurinda ya NBSiC ifite inshingano ebyiri z'ingenzi hano, itanga ibisubizo byihariye.
a. Imiyoboro ifunze neza yo kurinda ibikoresho bishyushya
Mu itanura rishongesha aluminiyumu, ibintu bishyushya aluminiyumu ya silikoni ni ingenzi ariko bishobora kwangirika bitewe n’isuri ya aluminiyumu ishongeshejwe.Imiyoboro ya NBSiC ifunze neza ikora nk'uruzitiro, itandukanya ibintu bishyushya n'icyuma gishongeshejwe kugira ngo yongere igihe cyabyo cyo kubaho no kwirinda kwanduzwa.Ubushobozi bwazo bwo gutwara ubushyuhe bwinshi butuma ubushyuhe bukwirakwira neza, bigabanya ikoreshwa ry'ingufu. Zishobora guhindurwa mu murambararo (kugeza kuri mm 600) n'uburebure (kugeza kuri mm 3000), zihuza n'imiterere itandukanye y'itanura.
b. Ibyuma bitanga amashanyarazi byo gucukura amapine ya aluminiyumu
Udupira two guterura twa NBSiC (imiyoboro yo guterura) tworohereza urujya n'uruza rwa aluminiyumu ishongeshejwe kuva mu itanura kugera ku ibumba mu gukora amapine ya aluminiyumu. Hamwe n'uburyo bukonje bwo gucika >150MPa no kudashyuha neza (mu gihe cy'ubushyuhe bwa 1000℃ -icyumba), bituma urujya n'uruza rudahindagurika kandi rudashira—bigabanya inenge zo guterura (imyenge, ibyinjiramo) no kunoza umusaruro. Bitandukanye n'imiyoboro y'icyuma, NBSiC ntihumanya aluminiyumu ishongeshejwe, ikarinda ubuziranenge bw'ibicuruzwa.
3. Imikoreshereze y'ibinyabutabire n'ibikoresho byo mu ifuru: Ubudahangarwa bw'inkongi mu bidukikije birimo ubukana
Inganda zitunganya imiti (gucikamo ibikomoka kuri peteroli, gukora aside/alkali) n'amatanura ya keramike/ibirahuri bikora neza hamwe n'imyuka ikaze n'ubushyuhe bwinshi.Imiyoboro ya NBSiC irinda ibikoresho byo gushyushya n'ibikoresho bishyushya hano, bitewe n'ubudahangarwa bw'ingufu rusange.Mu byuma bicukura peteroli, birwanya ingese ya H₂S na CO₂ mu bushyuhe bwinshi; mu itanura rya keramike/ikirahure, birinda thermocouples ikirere cya oxidative no kwangirika, bigatuma ubushyuhe bugenzurwa neza ku bicuruzwa byiza.
Imiyoboro yo kurinda ya NBSiC ihuza uburyo bwo kuyungurura amafaranga n'imikorere idahindagurika, itanga igihe kirekire cyo kuyikoresha, kurinda ibikoresho by'ingenzi, no kuyihindura uko imeze. Byaba mu byuma, mu kuvura ubushyuhe, mu miti, cyangwa mu ngufu nshya, bitanga icyizere gikenewe kugira ngo bikomeze guhangana.Twandikire uyu munsi kugira ngo ushake ibisubizo byihariye ku bibazo byawe by’ubushyuhe bwinshi n’ingufu.
