Mu nganda zikora ubushyuhe bwinshi nko gukora sima, gukora ibyuma, no gukora ibirahure, ibikoresho birwanya ubushyuhe ni ingenzi cyane mu gutuma imikorere ihora ihagaze neza no kugenzura ikiguzi.Amatafari ya spinel ya Magnesia alumina, ni amahitamo meza ku bakoresha inganda ku isi, iratandukanye cyane n'ubushyuhe burambye, irwanya ingese, kandi ikaba irinda ibidukikije.Iyi mfashanyigisho iragaragaza ibintu by'ingenzi by'amatafari ya magnesia alumina spinel ku byo ukeneye mu nganda zawe.
1. Ibisobanuro bya Magnesia Alumina Spinel Bricks
Amatafari ya Magnesia alumina spinel ni ibikoresho bya asiderike bya alkaline bigizwe ahanini na magnesium oxyde ifite pure nyinshi (MgO, 80%-92%) na aluminium oxyde (Al₂O₃, 3%-14%). Ibyiciro byabyo by'ingenzi bya crystalline—periclase na magnesia-alumina spinel (MgO·Al₂O₃)—bikora imiterere ihamye binyuze mu gushyushya ubushyuhe bwinshi. Nk'uburyo budafite chromium aho gukoresha refractories gakondo, magnesia alumina spinel briefing yirinda imyuka ya chromium ifite uburozi, ikurikiza byuzuye amahame mpuzamahanga agenga ibidukikije.
2. Imiterere y'ingenzi ya Magnesia Alumina Spinel Bricks
Ibintu bidasanzwe biranga amatafari ya spinel ya magnesia alumina birimo:
- ① Ifite ubushyuhe bwinshi kandi ihagaze neza, ihangana n'ibihe 12-20 byo gukonjesha amazi kuri 1100°C;
- ② Irwanya ubushyuhe bwinshi cyane, ifite ubushyuhe bwa 2135°C kandi ikagira ubushobozi bwo gushonga mu gihe cy'ubushyuhe >1700°C;
- ③ Ubudahangarwa bukomeye bwo kwangirika no gushonga kw'ibintu biva mu bintu bidafite aside, imyuka ivanze n'ibyuma biva mu bintu bidafite aside, n'ibindi byuma biva mu bintu bidafite aside;
- ④ Ingufu zizewe z’imiterere, zifite ubucucike bungana na ≥2.90 g/cm³ n’imbaraga zo gusya zikonjesha ≥45 MPa.
3. Imikoreshereze y'ingenzi ya Magnesia Alumina Spinel Bricks
Amatafari ya Magnesia alumina spinel ni meza cyane mu bidukikije bishyuha cyane: ahantu hahindagurika amatafari ya sima, imitako y'icyuma, imashini zivugurura amatafari y'ibirahure, n'imitako y'amatafari ya peteroli. Uburyo bwinshi bwo kuyakoresha butuma amatafari ya magnesia alumina spinel aba meza haba mu kirere cya alkaline ndetse no mu kirere kivanze.
4. Inama zo guhitamo amatafari ya Magnesia Alumina Spinel
Mu guhitamo amatafari ya magnesia alumina spinel, shyira imbaraga ku ngingo eshatu z'ingenzi: guhuza igipimo cya MgO/Al₂O₃ n'ikirere cy'imikorere yawe, kugenzura ibipimo by'ingenzi bya tekiniki (ubucucike bw'ingano, ubudahangarwa bw'ubushyuhe), no kugenzura impamyabushobozi z'ubuziranenge bw'umutanga.Shyira imbere amatafari ya magnesia alumina spinel yapimwe mu nganda zawe kugira ngo ubone umusaruro mwiza kandi urambe igihe kirekire.
Amatafari ya Magnesia alumina spinel ahuza imikorere n'uburambe, bigatuma aba ishoramari ryiza ku nganda zigezweho zikoresha ubushyuhe bwinshi. Hitamo amatafari ya Magnesia alumina spinel akwiye kugira ngo wongere ubwizigame bw'ibikoresho kandi ugabanye ikiguzi cyo kubibungabunga.
