‌Amatafari ya Magnesia-chromeni ibikoresho by'ibanze birwanya ubushyuhe birimo magnesium oxyde (MgO) na chromium trioxide (Cr2O3) nk'ibice by'ingenzi. Ifite imiterere myiza nko kudakomera cyane, kudashyuha cyane, kudasimbuka no kurwanya isuri. Ibice byayo by'ingenzi by'amabuye y'agaciro ni periclase na spinel. Ibi bintu bituma amatafari ya magnesia-chrome akora neza mu bushyuhe bwinshi kandi akwiriye ibikoresho bitandukanye by'inganda bishyuha cyane.

Ibikoresho n'uburyo bwo kubitunganya‌

Ibikoresho by'ingenzi by'amatafari ya magnesia-chrome ni magnesia na chromite bivanze. Magnesia ifite isuku nyinshi, mu gihe imiterere ya chromite isanzwe iba iri hagati ya 30% na 45%, naho ingano ya CaO ntirenga 1.0% kugeza 1.5%. Uburyo bwo kuyikora burimo uburyo bwo kuyihuza mu buryo butaziguye n'uburyo bwo kuyikoresha mu kudakoresha umuriro. Amatafari ya magnesia-chrome ahuza mu buryo butaziguye akoresha ibikoresho fatizo bifite isuku nyinshi kandi akoreshwa ku bushyuhe bwinshi kugira ngo akore uburyo bwo kuyihuza mu buryo butaziguye bwa periclase na spinel, ibyo bikaba birushaho kunoza imbaraga z'ubushyuhe bwinshi no kudakoresha slag.

Ibiranga imikorere
‌Irwanya cyane:Ubusanzwe ubushyuhe burenze 2000°C, kandi bushobora kugumana imiterere myiza mu gihe ubushyuhe bwinshi bukabije.
Ubudahangarwa bw'ingufu zikomoka ku bushyuhe:Bitewe n'uko ubushyuhe budahagije, ishobora guhangana n'impinduka zikomeye mu bushyuhe.
Ubudahangarwa bw'imyanda:Irwanya cyane ibisigazwa bya alkaline na bimwe mu bisigazwa bya aside, kandi ikwiriye cyane cyane ahantu hahura n'ibisigazwa by'ubushyuhe bwinshi.
Ubudahangarwa ku ngaruka:Ifite ubushobozi bwo kwihanganira isuri ihindagurika hagati y’aside n’isuri iterwa n’imyuka.
‌Ubudahangarwa bw'imiti:Umuti ukomeye ukorwa na oxide ya manyeziyumu na oxide ya chromium mu matafari ya magnesia-chrome ufite ubushobozi bwo guhagarara neza mu bya shimi.

Ahantu ho gushyiramo porogaramu
Amatafari ya manyeziyumu-chrome akoreshwa cyane mu nganda z'ibyuma, sima n'ibirahure:

Inganda z'ibyuma:ikoreshwa mu gushyira ibikoresho bishyushya cyane nka converters, amatanura y'amashanyarazi, amatanura afunguye, amatanura n'amatanura yo guturika mu nganda z'ibyuma, cyane cyane akwiriye ibidukikije byo gufata amatanura y'ubushyuhe bwinshi.

‌Inganda za sima:ikoreshwa mu gace ko gucana no mu gace k’impinduka k’amatanura ya sima kugira ngo irwanye kwangirika k’ubushyuhe bwinshi n’ikirere cya alkaline.

Inganda z'ibirahure:ikoreshwa mu kuvugurura no mu bice byo hejuru by’ibishushanyo mbonera mu itanura rishongesha ikirahure, kandi ishobora kwihanganira kwangirika k’ikirere gishyushye cyane n’amazi y’ikirahure afite alkaline.
