Wopangidwa kuchokera ku high purity magnesia ndi Bayer process alumina mu ng'anjo yayikulu yamagetsi yamagetsi. Ili ndi zinthu zabwino kwambiri zokanira, ndipo imatha kugwiritsidwa ntchito kupanga Njerwa ndi Castables m'malo omwe kukana kwa slag ndikofunikira.
Monga: Denga la EAF ndi ng'anjo yoyambira ya okosijeni, chitsulo chachitsulo, malo apakati a simenti yozungulira ng'anjo, etc.

Chiyambi cha malonda:Fused magnesia-aluminium spinel amapangidwa ndi aluminiyamu yotsika kwambiri ya sodiamu ufa wonyezimira kwambiri woyaka ngati zida zopangira, ndipo amasungunuka mu ng'anjo yamagetsi yamagetsi yotentha kwambiri kuposa 2000 ℃.
Zogulitsa:kukana kutentha kwambiri, kachulukidwe kakang'ono ka thupi, kuyamwa kwamadzi otsika, kagawo kakang'ono kakuwonjezera kutentha, kukhazikika kwamphamvu kwamafuta, kukana kwa dzimbiri komanso kukana kwa slag.
Poyerekeza ndi njira yopangira sintering kuti apange spinel, njira ya electrofusion imakhala ndi kutentha kwapamwamba kwa calcination, pafupifupi 2000 ° C, yomwe imapangitsa kuti spinel denser, ikhale ndi kuchuluka kwa voliyumu, ndipo imagonjetsedwa kwambiri ndi hydration. Njirayi ndi yofanana ndi njira ya sintering yopangira spinel.
Zopangira zake makamaka zimagwiritsa ntchito aluminiyamu yamafakitale ndi ufa wapamwamba kwambiri woyaka ndi magnesium oxide ufa.
Kugwiritsa ntchito mankhwala:Amagwiritsidwa ntchito kwambiri pakusungunula zitsulo, denga la ng'anjo yamagetsi, ladle, ng'anjo ya simenti, ng'anjo yamagalasi yamafakitale ndi mafakitale azitsulo, etc.Ndizinthu zabwino zopangira kuponyera mosalekeza
ma skateboards, njerwa za nozzles, njerwa zomangira ladle ndi njerwa za ng'anjo yafulati, komanso simenti yayikulu yopangira zida zoyatsira, njerwa zomangira za simenti zazikuluzikulu zapakatikati, njerwa zomangira ndi njerwa zapanyumba zotentha kwambiri komanso zapakatikati.
Kupanga kwa kampani ya aluminium yosakanikirana ya magnesium spinel ili ndi magawo ambiri, malinga ndi zomwe ogwiritsa ntchito amafunikira, kukula kwa tinthu, fineness ikhoza kupangidwa pakufunika.
