Igiciro gishimishije cy'ifuru Al2O3 65% 75% Ibumba rifite aluminiyumu nyinshi rikoreshwa mu ifuru ya Coke
Dufite itsinda rikora neza cyane rikemura ibibazo by'abakiriya. Intego yacu ni "kwishimira abakiriya 100% binyuze mu gutanga igisubizo cyacu cyiza, igiciro na serivisi nziza ku bakozi bacu" kandi twishimira amateka meza hagati y'abaguzi. Hamwe n'inganda nyinshi, dushobora kwerekana ubwoko butandukanye bw'ibicuruzwa.Amatafari ya Refractory n'ay'Alumina menshi mu BushinwaTumaze imyaka irenga 20 dukora ibicuruzwa byacu. Dukora cyane cyane ibicuruzwa bigurishwa ku giciro gito, bityo dufite igiciro cyiza cyane, ariko gifite ubuziranenge bwo hejuru. Mu myaka ishize, twabonye ibitekerezo byiza cyane, atari ukubera ko dutanga ibicuruzwa byiza gusa, ahubwo no kubera serivisi nziza twatanze nyuma yo kugurisha. Turi hano tugutegereje kugira ngo ubaze ikibazo cyawe.
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%.
