Isaro rireremba ni ubwoko bw'umupira w'umukungugu w'ivu ushobora kureremba hejuru y'amazi. Ni ibara ry'umweru w'ikijuju, rito kandi rifite ubugari mu rukuta, ryoroheje cyane, rifite uburemere bwa 720kg/m3 (riremereye) na 418.8kg/m3 (ryoroheje), ingano y'uduce twa mm 0.1, rifunze kandi ryoroshye mu buso, rito mu bushyuhe, kandi rirwanya umuriro ≥ 1610 ℃. Ni ikirahure cyiza cyane kirinda ubushyuhe, gikoreshwa cyane mu gukora ibikoresho byoroheje byo gucukura no gucukura amavuta. Ibigize isaro rireremba ahanini ni dioxyde silicon na oxide aluminiyumu. Rifite imiterere myinshi, nko utunyangingo duto, ubugari, uburemere bworoshye, imbaraga nyinshi, kudashira, kudashyuha cyane, gukingira ubushyuhe, gukingira ubushyuhe no kudashira kw'inkongi y'umuriro. Ni kimwe mu bikoresho fatizo bikoreshwa cyane mu nganda zirwanya inkongi.

Intangiriro

Imikorere myiza cyane n'ikoreshwa ry'amasaro areremba

Ubudahangarwa ku muriro mwinshi. Ibice by'ingenzi bya shimi bigize urusaro ruremba ni silicon na aluminium oxyde, muri byo silicon dioxide ingana na 48-66% naho aluminium oxyde ingana na 26-36%. Kubera ko aho silicon dioxide ishongesha ari 1720 ℃ naho aluminium oxyde ikaba 2060 ℃, byombi ni refractories nyinshi. Kubwibyo, urusaro ruremba rufite refractories nyinshi cyane, muri rusange zigera kuri 1620-1800 ℃, bigatuma rugira refractory nziza cyane. Uburemere bworoheje, ubushyuhe butuma ibintu bishyuha. Urukuta rw'urusaro ruremba ni ruto kandi rufite ubugari, kandi umwobo ni semi vacuum. Hariho gaze ntoya cyane (N2, H2, CO2, nibindi), kandi ubushyuhe bugenda buhoro cyane. Kubwibyo, urusaro ruremba ntabwo ari rworoshye gusa mu buremere (250-450 kg/m3). Ingano karemano y'uduce tw'urusaro ruremba ni mikoroni 1-250. Udusaro dushobora gukoreshwa mu buryo butaziguye tudasya. Ubunini bushobora guhaza ibyifuzo by'ibicuruzwa bitandukanye. Ibindi bikoresho byoroshye byo gukingira ubushyuhe muri rusange bifite ubunini bunini bw'uduce duto (nka perlite). Iyo bikubiswe, ubushobozi buziyongera cyane, kandi ubushyuhe buzagabanuka cyane. Muri urwo rwego, amasaro yo gushyushya afite ibyiza. Ubushyuhe bwiza cyane bw'amashanyarazi. Isaro yo gukingira nyuma yo gutoranywa kwa magnetique ni ibikoresho bikingira ubushyuhe bifite imikorere myiza kandi ntibikoresha amashanyarazi. Muri rusange, ubushyuhe bw'amasaro yo gukingira bugabanuka uko ubushyuhe bwiyongera, mu gihe ubushyuhe bw'amasaro yo gukingira buzamuka uko ubushyuhe bwiyongera. Iyi nyungu ntabwo iri mu bindi bikoresho bikingira ubushyuhe. Kubwibyo, ishobora gukoreshwa mu gukora ibikoresho bikingira ubushyuhe mu gihe cy'ubushyuhe bwinshi.
