Hejuru ya Alumina Yangiza Isima Ibisobanuro
Isima ryinshi rya alumina ikorwa muguhuza ibikoresho byatoranijwe byatoranijwe mu itanura ridasanzwe. Nyuma yo gukonja, clinker iri hasi ikoresheje urusyo. Ibikoresho fatizo bya alumina yo mu bwoko bwa sima CA-70 ni ibikoresho bya calcium byera cyane na alumina nziza. Ibikoresho fatizo bigomba kuvangwa ukurikije igipimo gikwiye. Ibikoresho fatizo bigomba gutwikwa kugirango igice kimwe. Ibiri muri Al2O3 mubisanzwe bigenzurwa muri 68% kugeza 72%. Ibyingenzi byingenzi byayo ni CA na CA2.
Ibyiza bya Alumina yo hejuru ya sima
- Kwihuta-gukomera, imbaraga nyinshi,
- Kwanga cyane, imikorere yubushyuhe bwo hejuru,
- Kurwanya neza abrasion, kwihanganira kwambara cyane,
- Ubushobozi bwo kuyobora neza,
- Imikorere myiza yo kurwanya ruswa,
- Ihungabana ryinshi ryumuriro.
Ibyiza bya Alumina Yumuti wo hejuru
1.Imikorere myiza kumashanyarazi, ruswa, isuri no kurwanya abrasion,
2.Ubusumbane bukabije n'imbaraga zidasanzwe za mashini,
3.Byombi burigihe kandi burigihe uburyo bwo gukora buremewe, kugabanya ibice byumurongo,
4.Ubuzima burebure kandi butajegajega kugirango bugere kubikorwa byiza,
5.Kwambara ubwoko bwubwoko bwose bwicyuma, gabanya ibisigara nubushake bwibicuruzwa,
6.Umurimo nigiciro cyo kuzigama mugushiraho byoroshye no kubungabunga.

Gukoresha Amashanyarazi Yisumbuye ya Alumina
Isima ya alumina nini ikoreshwa cyane cyane mubyifuzo byihariye byo kubaka byihutirwa, gusana byihutirwa, kurwanya sulfate no kubaka imbeho. Kandi sima ndende ya alumina yamashanyarazi ikoreshwa cyane cyane muri gahunda zihutirwa zumushinga, nko kwirinda igitutu, umuhanda n’imishinga idasanzwe yo gusana. Na sima ndende ya alumina ciment yakoreshejwe ahantu hakurikira:
- Kubaka sulfate irwanya ruswa hamwe nubushyuhe bwo hejuru,
- Ikoreshwa mugusana byihuse, guhagarara kumeneka, kurwanya igitero cya sulfate,
- Icyuma cyiza cyo kuvunika nka beto yangiritse, gutobora ibintu, kuvanga kuvanga, kuvanga imbunda n'amatafari ya marimari yakozwe,
- Byakoreshejwe nkibikoresho bya ceramic,
- Ikoreshwa mugushiraho ibicuruzwa bitwikiriye hamwe na minisiteri yangiritse,
- Ikoreshwa mu nganda zikora imiti, inganda zibyuma, ibikoresho byubwubatsi.
Uruganda rukomeye rwa Alumina rukora sima rukora uruganda rwa RS
Uruganda rwa RS rutunganya inganda ni aluminiyumu wabigize umwuga utanga sima watangiye mu ntangiriro ya 90 yikinyejana cya makumyabiri. Uruganda rwa RS rugizwe ninzobere muri sima ya alumina mumyaka irenga 20. niba ufite ibyo ukeneye bya sima ya alumina yo hejuru, cyangwa ufite ibibazo kuri zircon mulite refractory bricabout ibipimo byumubiri na chimique, nyamuneka twandikire kubuntu. n'amafaranga yinganda zinganda nkumwuga wa zircon mulite wamatafari wamatafari mubushinwa, afite ibyiza byo guhatanira gutya:
- Igiciro cyo Kurushanwa: Kora ibicuruzwa birushanwe kumasoko yawe,
- Ubunararibonye Bwinshi: Irinde gucamo no kugoreka amatafari,
- Ibishushanyo bitandukanye: Bika amafaranga yububiko kuri wewe,
- Igenzura rikomeye: Kuzuza ubuziranenge bwabakiriya,
- Ibigega binini: Kwemeza gutanga vuba,
- Gupakira umwuga: Irinde kwangirika no kurinda ibicuruzwa mu bwikorezi.
