Mu nganda aho ubushyuhe bwinshi, umuvuduko, n'ibikoresho bigerageza kwangirika, ibisubizo byizewe ni ingenzi cyane.Amatafari ya SillimaniteBagaragara nk' "abakora mu nganda," bafite imiterere idasanzwe yongera imikorere, igabanya ikiguzi, kandi ikongera ireme ry'ibicuruzwa mu buhanga bw'ibyuma, ibumba, n'ibirahuri. Dore impamvu ari amahitamo akomeye ku isi yose.
1. Imiterere y'ingenzi: Ni iki gituma amatafari ya Sillimanite aba ingenzi
Aya matafari akomoka kuri sillimanite y’amabuye y’agaciro ya aluminosilicate, atanga ibyiza bitatu bidasanzwe:
Ubushobozi bwo kugarura umwuka ku rugero rwo hejuru cyane:Kubera ko ubushyuhe burenze 1800°C, birwanya ubushyuhe bukabije (ni ingenzi mu gushonga kw'ibyuma no gushonga kw'ibirahuri, aho ubushyuhe burenze 1500°C) nta guhindagurika cyangwa kwangirika.
Kwaguka k'ubushyuhe buke:Igipimo kiri munsi ya 1% kuri 1000°C kirinda gucika kw'ingufu ziterwa n'ubushyuhe, bigatuma biramba mu buryo bushyuha n'ubukonje nk'amatanura ashyuha.
Ubudahangarwa Bukomeye:Kubera ko ari nyinshi kandi zikomeye, zihanganira kwangirika kw'ibyuma bishongeshejwe/ibisigazwa ndetse n'isuri ya shimi ituruka kuri aside/alkali—ni ingenzi mu gutunganya no gukoresha ibyuma mu bucukuzi bw'amabuye.
Izi ngeso zihindura amatafari ya sillimanite kuva ku "byiza kugira" bikajya ku "bigomba kuba bifite" kugira ngo birusheho kunozwa.
2. Ubuhanga mu by'ibyuma: Kongera umusaruro w'ibyuma n'ibyuma
Inganda zikora ibyuma zikoresha cyane amatafari ya sillimanite mu bikoresho bikoresha ubushyuhe:
Imitako y'ifuru yo mu bwoko bwa Blast Furnace:Binyuze mu "gace gashyushye" (1500–1600°C) k'amatanura akora ibyuma, biraruta amatanura asanzwe. Uruganda rw'ibyuma rwo mu Buhinde rwabonye igihe kirekire cyo kumara amatanura ku kigero cya 30% kandi ikiguzi cyo kuyatunganya cyagabanutseho 25% nyuma yo kuyahindura.
Udupira twa Tundish na Ladle:Bigabanya kwanduza ibyuma no kongera igihe cyo gukoresha ibyuma kugeza kuri 40% (kuri buri mucuzi w’ibyuma w’i Burayi), bituma ibyuma bishongeshwa bifatwa neza.
Ibyuma byo gusenya sulfure:Ubudahangarwa bwazo n'ibisigazwa bikungahaye kuri sulfure bukomeza kumera neza, bigafasha kugera ku mahame akaze yo gutunganywa mu byuma.
Ku bahanga mu by'ibyuma, amatafari ya sillimanite ni ishoramari rikomeye mu musaruro.
3. Ibumba: Amatafari yo kongera imbaraga, ibikoresho by'isuku n'ibumba rya tekiniki
Mu byuma bibumba, amatafari ya sillimanite afite inshingano ebyiri z'ingenzi:
Udupira two mu gikoni:Kubungabunga ubushyuhe bungana (kugeza kuri 1200°C) mu itanura rikoresha umuriro, bituma kwaguka kwabyo kugabanuka birinda kwangirika. Umucuruzi w’amatafari wo mu Bushinwa yagabanyije amafaranga y’ingufu ho 10% nyuma yo kuyavugurura, aho ikoreshwa ry’ingufu muri rusange ryagabanutseho 15–20%.
Inyongeramusaruro ku bikoresho fatizo:Ifu isya (5–10% mu bivange), yongera imbaraga za mekanike (imbaraga zo kwihuta ziyongeraho 25%) kandi ikanatuma ubushyuhe buguma neza (ibyangiritseho 30% mu bushyuhe) mu byuma bya tekiniki bya ceramic.
4. Gukora ikirahure: Kugabanya ubuziranenge n'ikiguzi?
Amatafari ya Sillimanite akemura ibibazo bikomeye byo gukora ibirahuri:
Ibikoresho bivugurura amatanura:Kubera ko zifata ubushyuhe, zirinda kwangirika no kwinjira mu gihu cy’ibirahuri. Uruganda rukora amatafari rwo muri Amerika y’Amajyaruguru rwabonye igihe cy’imyaka 2 cyo gukomeza amatafari, rugabanya ikiguzi cyo gusimbuza amatafari ho $150.000 kuri buri itanura.
Ikirahure cyihariye:Bifite munsi ya 0.5% ya oxide y'icyuma, birinda kwanduza ikirahuri cy'urumuri cyangwa borosilicate, bigatuma habaho ubwiza n'ubudahangarwa bw'imiti kuri ecran za labware cyangwa za terefone zigendanwa.
5. Inganda zikora imiti n'izindi: Gukemura ibibazo bikomeye
Gutunganya imiti:Bitwikira ibyuma bitanga ubushyuhe bwinshi, birinda amazi gusohoka kandi byongera igihe cyo gukoresha ibikoresho—ni ingenzi cyane mu mutekano mu ifumbire mvaruganda, peteroli, cyangwa imiti.
Gutwika imyanda:Birwanya ubushyuhe bwa 1200°C no kwangirika kw'imyanda, bigabanya kubungabunga inganda zikoresha imyanda mu gutanga ingufu.
Hitamo amatafari ya Sillimanite kugira ngo ugire intsinzi irambye
Waba urimo umwuga wo gukora ibyuma, uruganda rukora ibumba, cyangwa uruganda rw'ibirahure, amatafari ya sillimanite atanga umusaruro. Uruvange rwayo rudasanzwe rwo kudakomera, kwaguka gake, no kudakomera bituma iba igisubizo gihendutse kandi gikoreshwa mu buryo butandukanye.
Witeguye kuvugurura? Vugana n'ikipe yacu kugira ngo ubone ibiciro byihariye n'ubufasha mu bya tekiniki. Nimuze twubake ahazaza h'inganda heza kurushaho—turi kumwe.
