Uruganda rw'Ubushinwa rukora ubukana bw'ubukonje bwa Alumina nyinshi, ibumba rya Bauxite ry'Ubushinwa rikoreshwa mu gukurura ubukonje.
Dukomeza gukurikiza ihame rya "ubuziranenge bwa mbere, ubufasha bwa mbere, kunoza no guhanga udushya kugira ngo duhuze abakiriya" ku buyobozi bwawe, kandi intego ya "nta nenge, nta kirego na kimwe" ni uko ari yo ntego isanzwe. Mu rwego rwo kunoza serivisi zacu, dutanga ibicuruzwa n'ibisubizo mu gihe dukoresha ubwiza bwiza ku giciro cyiza kuriAlumina yakozwe na Alumina y'umukara yakuwemo, Ni abanyamideli bakomeye kandi bateza imbere ibikorwa byabo ku isi yose. Ntabwo bizigera bibura imirimo ikomeye mu gihe gito, ni ngombwa ko mu gihe ufite ireme ryiza cyane. Tuyobowe n'ihame rya "Ubushishozi, Ingufu, Ubumwe n'Udushya." Ikigo gishyira imbaraga mu kwagura ubucuruzi bwacyo mpuzamahanga, kuzamura ikigo cyacyo, kunoza no kuzamura urwego rwacyo rwo kohereza ibicuruzwa mu mahanga. Twizeye ko tuzagira amahirwe meza kandi ko tuzakwirakwira ku isi yose mu myaka iri imbere.
Amatafari afite alumina nyinshi kandi adafite icyuma gikingirani ubwoko bw'ibikoresho birwanya aluminiyumu bifite aluminiyumu nk'igice cy'ingenzi. Bifite aluminiyumu irenga 48%, bishyirwa mu byiciro by'ibikoresho birwanya aluminiyumu bitagira aho bibogamiye, bikozwe muri bauxite cyangwa ibindi bikoresho fatizo bifite aluminiyumu nyinshi binyuze mu gushushanya no gukaranga.
Ishyirwa mu byiciro:
Hashingiwe ku ngano ya alumina, bigabanyijemo ibyiciro bitatu:
Icyiciro cya 1: amatafari afite alumina nyinshi (ibipimo bya Al₂O₃ > 75%)
Icyiciro cya 2: amatafari afite alumina nyinshi (ibipimo bya Al₂O₃: 60%~75%)
Icyiciro cya 3: amatafari afite alumina nyinshi (ibipimo bya Al₂O₃: 48%~60%)
Imiterere isanzwe y'amatafari n'amahitamo yihariye:
Amatafari asanzwe, amatafari yo ku rukuta, amatafari yo gukata, amatafari agoramye, amatafari y'inkingi, amatafari y'inkingi, amatafari y'imirongo ine, amatafari yo gucukura, n'imiterere yihariye hakurikijwe ibishushanyo/ingero by'umukiriya.
Imiterere ya fizikikemike:
1. Kudahinduka kw'amabara
Ishobora kwihanganira ubushyuhe bwinshi buri hejuru ya 1770℃, muri rusange kuva kuri 1750℃ kugeza 1790℃. Ubushobozi bwo guhagarara buriyongera uko ingano ya alumina izamuka.
2. Ubushyuhe bwo koroshya imizigo
Muri rusange ni 1420℃ ~ 1530℃. Bitewe n'ubwinshi bw'alumina, ubwinshi bw'umwanda buke n'imiterere mike y'ikirahure gihindagurika, ubushyuhe bwo koroshya umutwaro wacyo buri hejuru y'ubw'amatafari y'ibumba ritwikwa.
3. Imbaraga zo gukanda zikonjesha
Ubukonje bw'amatafari ya alumina yo mu cyiciro cya mbere (LZ-80) ni ≥ 70 MPa, mu gihe aya alumina yo mu cyiciro cya gatatu (LZ-48) ari ≥ 40 MPa.
4. Ubudahangarwa bw'imyanda
Amatafari afite alumina nyinshi yegereye ibikoresho bitagira aho bibogamira, bishobora kurwanya kwangirika kw'ibisigazwa bya aside na alkaline, ariko kurwanya ibisigazwa bya aside ni bike ugereranyije n'ibisigazwa bya aside.
5. Kugaragara ko hari porosity
Uburemere bw'amatafari ya alumina yo mu cyiciro cya mbere ni ≤ 21%, naho ubw'amatafari ya alumina yo mu cyiciro cya gatatu ni ≤ 22%.

Amatafari menshi ya aluminaakoreshwa cyane cyane mu bikoresho bya VOD, AOD, amatanura ashyushye, amatanura ashyushye, EAF, amatanura ahindura imiterere y'amatanura, n'amatanura azunguruka. Byongeye kandi, amatafari maremare ya alumina akoreshwa cyane nk'amatafari afunguye yo kubika ubushyuhe, amatafari yo gusukamo, amatafari yo kunyweramo, n'ibindi.
Ibibazo Bikunze Kubazwa
Ukeneye ubufasha? Menya neza ko usura urubuga rwacu rw'ubufasha kugira ngo uhabwe ibisubizo by'ibibazo byawe!
Turi uruganda nyakuri, uruganda rwacu rwihariye mu gukora ibikoresho birwanya ubushyuhe mu gihe kirenga imyaka 30. Twizeza gutanga igiciro cyiza, serivisi nziza mbere yo kugurisha no nyuma yo kugurisha.
Kuri buri gikorwa cyo gukora, RBT ifite sisitemu yuzuye ya QC y’imiterere ya chimique n’imiterere ifatika. Kandi tuzagerageza ibicuruzwa, kandi icyemezo cy’ubuziranenge kizatangwa hamwe n’ibicuruzwa. Niba ufite ibisabwa byihariye, tuzagerageza uko dushoboye kose kugira ngo tubigereho.
Bitewe n'ingano, igihe cyo kohereza kiratandukanye. Ariko twizeza kohereza vuba bishoboka kandi bifite ubuziranenge bwemejwe.
Birumvikana ko dutanga ingero ku buntu.
Yego, birumvikana ko mufite ikaze gusura ikigo cya RBT n'ibicuruzwa byacu.
Nta mupaka uhari, dushobora gutanga igitekerezo cyiza n'igisubizo gikwiye bitewe n'imimerere yawe.
Tumaze imyaka irenga 30 dukora ibikoresho birwanya ubushyuhe, dufite ubufasha bukomeye mu bya tekiniki n'uburambe bwinshi, dushobora gufasha abakiriya gushushanya amatanura atandukanye no gutanga serivisi imwe.
