Ibisobanuro bya sima ifite alumina nyinshi ihindura imiterere y'isima
Sima ifite alumina nyinshi ikorwa binyuze mu guhuza ibikoresho fatizo byatoranijwe mu itanura ryihariye. Nyuma yo gukonjesha, clinker irasya hakoreshejwe ibyuma bitunganya imipira. Ibikoresho fatizo bya sima ifite alumina nyinshi CA-70 ni ibikoresho bya kalisiyumu nziza cyane na alumina nziza cyane. Ibikoresho fatizo bigomba kuvangwa hakurikijwe igipimo gikwiye. Ibikoresho fatizo bigomba gutwikwa kugira ngo bifatanye. Ingano ya Al2O3 isanzwe igenzurwa hagati ya 68% na 72%. Ibikoresho by'ingenzi muri byo ni CA na CA2.
Imiterere ya sima ifite alumina nyinshi ihindura imiterere y'umubiri
- Gukomera vuba, imbaraga nyinshi,
- Ingufu nyinshi zo kugabanya ubushyuhe, serivisi zitanga umusaruro mwinshi,
- Ubudahangarwa bwiza bwo kwangirika, budahangarwa cyane,
- Ubushobozi bwo kuruhura amazi buhamye,
- Imikorere myiza yo kurwanya ingese,
- Ubushyuhe bwinshi butuma umuntu adashobora guhagarara neza.
Ibyiza byo gukoresha sima ifite alumina nyinshi
1. Imikorere myiza mu kurwanya ubushyuhe, ingese, isuri n'ubudahangarwa bw'ibimera,
2.Ingufu nyinshi zo guhagarara neza no gukomera cyane mu buryo bwa mekanike,
3. Uburyo bwo gukora buri gihe no mu buryo buhoraho burakwiriye, bugabanya imiyoboro y'imbere,
4. Ubuzima burebure kandi buhamye kugira ngo bugere ku musaruro mwiza,
5. Ikwiriye ubwoko bwose bw'ibyuma, igabanya ibisigazwa n'imyenge y'ibicuruzwa,
6. Gutanga akazi no kuzigama amafaranga binyuze mu gushyiraho no kubungabunga byoroshye.

Gukoresha sima ifite alumina nyinshi igabanya ubukana bw'ingufu
Sima ifite alumina nyinshi ikoreshwa cyane cyane mu bikorwa byihariye byo kubaka byihutirwa, gusana byihutirwa, kurwanya sulfate no kubaka mu gihe cy'itumba. Kandi sima ifite alumina nyinshi ikoreshwa cyane cyane mu bikorwa byihutirwa by'imishinga, nko kurinda umuvuduko w'amashanyarazi, imihanda n'imishinga yihariye yo gusana. Nanone sima ifite alumina nyinshi ikoreshwa aha hakurikira:
- Kubaka uburyo bwo kurwanya ingese ya sulfate no kwirinda ubushyuhe bwinshi,
- Ikoreshwa mu gusana imashini zihuta cyane, guhagarika amazi ava, kurwanya ibitero bya sulfate,
- Igikoresho cyiza cyo gufunga ibintu bidashobora guhindagurika nka beto idashobora guhindagurika, ikoreshwa mu gukubita, kuvanga ibintu bidashobora guhindagurika, kuvanga imbunda n'amatafari ya marble akozwe n'abantu,
- Ikoreshwa nk'ubudodo bwa keramike,
- Ikoreshwa mu gufunga ibikoresho byo gusiga no mu gufunga ibintu birekuye,
- Ikoreshwa mu nganda zikora imiti, ibyuma, ibikoresho by'ubwubatsi.
Uruganda rukora sima ishyushye cyane ya alumina ikomoka ku ruganda rwa RS Refractory
Uruganda rwa RS rukora sima ikora alumina nyinshi kandi idafite alumina nyinshi, rwashinzwe mu ntangiriro z'ikinyejana cya makumyabiri. Uruganda rwa RS rukora sima idafite alumina nyinshi mu gihe cy'imyaka irenga 20. Niba ukeneye sima idafite alumina nyinshi kandi idafite alumina nyinshi, cyangwa ufite ibibazo ku bimenyetso bya fiziki n'imiti bya zircon mulite, twandikire ku buntu. Kandi uruganda rwa Rs rukora sima idafite alumina nyinshi kandi idafite alumina nyinshi mu Bushinwa, rufite inyungu zimwe na zimwe zo guhangana nazo nk'izi zikurikira:
- Igiciro Gihiganwa: Hindura ibicuruzwa bihiganwa ku isoko ryawe,
- Ubunararibonye bwinshi: Kurinda imiturire no kugorama kw'amatafari,
- Ibikoresho bitandukanye: Zigama amafaranga y'ibikoresho kuri wewe,
- Igenzura ry’Ubuziranenge Rihamye: Uzuza ibisabwa n’abakiriya ku rwego rw’ubuziranenge,
- Imigabane minini: Gutanga garanti ku gihe,
- Gupakira by'umwuga: Irinde kwangirika no kubika neza ibicuruzwa mu gihe cyo kubitwara.
