Amatafari ya chrome ya Magnesiani ibikoresho by'ingenzi birwanya ubushyuhe bwinshi ku matanura, bikoreshwa cyane mu matanura azunguruka ya sima, mu matanura akora ibyuma, mu matanura adafite feri n'amatanura y'ibirahure. Imikorere yabyo igena mu buryo butaziguye igihe cyo gukora, imikorere myiza n'umutekano w'umusaruro. Kugira ngo uhitemo amatafari ya magnesia chrome akwiye, ugomba guhuza neza imiterere yayo n'imiterere y'imikorere y'itanura—iyi ni yo ngingo yo kugabanya ikiguzi cyo kubungabunga no kongera inyungu mu mikorere.
Ubwa mbere, shyira imbaraga ku bushyuhe bw'imikorere y'itanura. Amatanura atandukanye afite ubushyuhe butandukanye: ahantu hatwikirwa sima zigera kuri 1500–1650°C, mu gihe amatanura y'amashanyarazi akora ibyuma ashobora kurenza 1700°C. Amatafari ya magnesia chrome meza agomba kugira ubushyuhe burenga 2000°C n'ubushyuhe bworoshye burenga 1550°C kugira ngo agumane ubuziranenge mu gihe cy'ubushyuhe bwinshi bw'igihe kirekire. Ku matanura y'ubushyuhe bwinshi cyane, hitamo amatafari ya magnesia chrome yasubiwemo kandi afite ubushyuhe bwinshi buhamye.
Icya kabiri, tekereza ku bidukikije by’ibinyabutabire by’itanura. Ibikoresho bitunganya alkali (nk’icyuma gikozwe muri sima) bisaba amatafari afite ubudahangarwa bukomeye na alkali, mu gihe abacunga icyuma gishongeshejwe cyangwa aside bakeneye ubudahangarwa bwiza na aside. Magnesia (MgO) mu matafari ya magnesia chrome itanga ubudahangarwa na alkali, mu gihe chromium oxide (Cr₂O₃) yongera ubudahangarwa bwa aside, bigatuma akwiriye ahantu hagoye ho gukorerwa ibinyabutabire. Ku matanura akunze gutwarwa n’isuri, hitamo amatafari afite ubudahangarwa buke (ubudahangarwa <20%) kugira ngo wirinde ko isuka ikwirakwira.
Icya gatatu, suzuma ubushobozi bwo guhangana n’ubushyuhe bushingiye ku ihindagurika ry’ubushyuhe. Amatanura afite imikorere ihoraho yo gutangira (nk’amatanura adakoresha feri) akeneye amatafari ashobora kwihanganira impinduka zihuse z’ubushyuhe adacitse. Amatafari ya magnesia chrome ya semi-rebonded atanga ubushobozi bwo guhangana n’ubushyuhe, bigatuma aba meza muri ubwo buryo, mu gihe ubwoko bw’amatanura ahuza imikorere n’ikiguzi cy’amatanura akoresha ubushyuhe buhamye.
Byongeye kandi, huza ubwoko bw'amatafari n'uturere twihariye tw'itanura. Ku bice bishobora kwangirika nko mu minwa y'itanura cyangwa imiyoboro y'amazi, hitamo amatafari akomeye cyane afite imbaraga zo gusya ubukonje bwa ≥35MPa. Ku miyoboro ihoraho, amatafari asanzwe ya magnesia chrome ahendutse kandi ahendutse akora neza, mu gihe imiyoboro y'ingenzi isaba ubwoko bw'ibikoresho bifatika cyangwa bisubiwemo.
Guhitamo amatafari ya magnesia chrome akwiye ntabwo ari ubwiza bw'ibikoresho gusa—ni uguhuza neza n'imiterere y'itanura. Amatafari yacu ya magnesia chrome meza, aboneka mu bwoko butandukanye n'ingano zihariye, yakozwe kugira ngo ahuze n'ibikenewe bitandukanye by'itanura, bigatuma amara igihe kirekire kandi agakoreshwa neza. Twandikire uyu munsi kugira ngo ubone igisubizo cyabigenewe ku itanura ryawe.
