Umuyoboro w'ubushyuhe wa Silicon Carbide Thermocouple urinda Nitride: Ingwate y'ingenzi yo gupima ubushyuhe buhamye

Mu nganda zikoresha ubushyuhe bwinshi nka sima, ibirahure, n'ibyuma bishongesha, kugenzura neza ibipimo by'ubushyuhe bigena neza umusaruro, igipimo cy'ibicuruzwa, n'umutekano w'imikorere. Imiyoboro gakondo yo kurinda thermocouple ikunze kwangirika no kwangirika kenshi bitewe no kudashobora kwihanganira ubushyuhe bukabije, isuri isanzwe ishongeshejwe, ndetse no kwangirika kw'ibinyabutabire. Ibi ntibyongera gusa ikiguzi cyo kubungabunga ibikoresho no gutakaza igihe cyo gukora ahubwo bishobora no gutera impanuka zo gukora bitewe no guhindagurika kw'ibipimo by'ubushyuhe. Bitewe n'inyungu zayo zidasanzwe z'ibikoresho, umuyoboro wo kurinda thermocouple wa nitride bonded silicon carbide (Si3N4-bonded SiC) wabaye igisubizo gikunzwe cyane mu gukemura ibibazo byo gupima ubushyuhe mu bihe bikomeye by'akazi, uhinduka cyane mu buryo bwo gupima ubushyuhe mu nganda zitandukanye zikenera cyane.

Mu itanura rizunguruka, ibikoresho by'ingenzi mu gukora sima, uyu muyoboro w'uburinzi ushobora kwihanganira ubushyuhe bwinshi buri hejuru ya 1300°C igihe kirekire, ukarwanya gukaraba cyane uduce duto twa sima clinker ndetse no kwangirika kwa gaze ihumanya iri mu itanura, ukarinda neza sensor ya thermocouple yubatswemo, kandi ukizera neza ko amakuru y'ubushyuhe mu bice by'ingenzi nka silindiri y'itanura n'ahantu hatwikwa, ugatanga inkunga yizewe yo kunoza uburyo bwo gukaraba sima no kugenzura ikoreshwa ry'ingufu. Mu ikorwa ry'itanura rishongesha ikirahure, urwanya neza isuri n'ubushyuhe bw'ikirahure bishobora kwirinda gusenyuka no kwangirika k'umuyoboro w'uburinzi, ukizera ko ubushyuhe bukomeza gukurikiranwa mu bice nka pisine n'umuyoboro, kandi ugafasha kunoza ubwisanzure n'ubunini bw'ibicuruzwa by'ikirahure byarangiye. Mu ikorwa ry'ibyuma nk'icyuma, aluminiyumu, n'umuringa, ushobora kurwanya gukaraba ubushyuhe bwinshi bw'icyuma gishongeshwa n'isuri y'ikirere gishyushye no kugabanya ogisijeni mu itanura, ukiyemeza gupima ubushyuhe bw'ibikoresho bitandukanye nka converters, amatanura y'amashanyarazi, n'ibikoresho bihoraho, kandi ukirinda guhagarara kw'ibipimo by'ubushyuhe biterwa no kwangirika kwa sensor.

Uretse ibikorwa by'inganda z'ingenzi, uyu muyoboro w'uburinzi ushobora no gukoreshwa mu bihe byihariye bishyuha cyane nko gutwika imyanda, amatanura ya ceramic, n'amasafuriya y'ubushyuhe bwinshi, bihuza n'imiterere itandukanye y'ubwoko bwa thermocouple. Imiterere yayo y'ingenzi nko kurwanya ubushyuhe bwinshi (kugeza kuri 1600℃), imbaraga nyinshi za mekanike, kurwanya ingese neza, no kurwanya ubushyuhe bwiza bishobora kongera cyane ubuzima bwa thermocouple inshuro 3-5, kugabanya cyane inshuro zo kubungabunga ibikoresho n'ikiguzi cyo gusimbuza, no kunoza imikorere ihoraho y'imirongo y'umusaruro. Guhitamo umuyoboro wacu w'uburinzi wa thermocouple wa silicon carbide ugizwe na nitride ntibishobora kuguha uburambe bwo gupima ubushyuhe neza kandi buhamye gusa ahubwo binagabanya igihombo cyo guhagarara kubera ko wizewe cyane, bigatuma ibigo bibasha kugera ku musaruro mwiza, ufite umutekano, kandi uhendutse.
