Amatafari ya Magnesia afite 90% bya magnesium oxide kandi akoresha periclase nk'icyiciro cy'ingenzi cya crystalline. Amatafari ya Magnesite ashobora kugabanywamo ibice bibiri bya Burnt Magnesia Bricks na Chemical Bonded Magnesite Bricks. Amatafari ya Magnesite afite imikorere myiza cyane, afite imbaraga nyinshi mu bushyuhe bwinshi n'ubwinshi buhamye. Kandi ashobora gukoreshwa mu bushyuhe buri hejuru ya 1750°C, amatafari ya Magnesite ni ibikoresho byiza byo gukoresha mu itanura ry'ibirahure.
Imiterere y'amatafari ya Magnesia
- Indwara nyinshi zo kugabanya imbaraga,
- Ubudahangarwa bw'imyanda ya alkali,
- Ubudahangarwa bw'isuri n'uburyo bwiza bwo kurwanya oxidation,
- Kurenza urugero cyane mu gihe cy'umutwaro,
- Ingufu nyinshi za mekanike,
- Ubudahangarwa bw'ingano ku bushyuhe buri hejuru.
Uburyo bwo gukora amatafari ya Magnesia
Amatafari ya Magnesia ashobora gushyirwa mu byiciro bibiri: amatafari ya Magnesite yahiye n'amatafari ya Magnesite afatanye na shimi. Amatafari ya Magnesite yahiye akorwa mu bikoresho fatizo bya periclase, nyuma yo gushya ubushyuhe buri hagati ya 1550 na 1600℃ binyuze mu gusya, kuvanga, gushonga no gusya. Ibikoresho bifite ubushyuhe bwinshi bifite ubushyuhe burenga 1750℃ bwahiye. Amatafari ya Magnesite adahiye akorwa mu kongeramo imiti ikwiye binyuze mu gushonga, gusya no kumisha.
Ibyiciro by'amatafari ya Magnesia
Bitewe n'imiterere itandukanye y'amatafari ya magnesia, ashobora gushyirwa mu byiciro bitandukanye, kandi aya matafari yose akorwa hakoreshejwe uburyo bwo gusya. Hashingiwe ku bikoresho fatizo bitandukanye, amatafari ya magnesia ashobora gushyirwa mu byiciro bikurikira:
Amatafari ya magnesia asanzwe: ibuye rya magnesite ryakozwe mu buryo bwa sintered.
Itafari rya magnesia rihuza direct bond: magnesite ifite sintered sintered high purity.
Itafari rya Forsterite: peridotite
Amatafari ya Magnesia calcia: magnesite ivanze irimo kalisiyumu nyinshi.
Amatafari ya silica ya Magnesia: ibuye rya magnesite rya silune rinini.
Amatafari ya chrome ya Magnesia: magnesite ya sintered na chrome ore zimwe na zimwe.
Amatafari ya Magnesia alumina: ibuye rya magnesite ryacukuweho na Al2O3.

Ikoreshwa ry'amatafari ya Magnesia mu itanura
Amatafari ya Magnesite akwiriye ubwoko bwose bw'amatanura ashyushye cyane, nk'amatanura akoresha ibyuma. Byongeye kandi, amatafari ya Magnesia akoreshwa cyane mu bindi bikoresho bishyushya, nk'amatanura akoresha amashanyarazi menshi, inkingi y'itanura rikoresha sima izunguruka, inkingi y'itanura rishyushya n'urukuta, icyumba cyo kuvugurura itanura ry'ibirahure, inkingi y'itanura ry'amashanyarazi n'urukuta n'ibindi.
Uruganda rw'amatafari ya Magnesia mu Bushinwa
Uruganda rukora amatafari ya magnesia rwa RS ni uruganda rw’umwuga rukora amatafari ya magnesia mu Bushinwa, rushobora kuguha amatafari meza ya magnesia. Niba ukeneye amatafari ya magnesia, cyangwa ufite ibibazo ku matafari ya magnesia ku bipimo ngenderwaho n’ibinyabutabire, twandikire ku buntu, ibicuruzwa byacu bizaguhamagara vuba bishoboka.
