Njerwa ya kaboni ya Magnesite alumina ndi mtundu wa njerwa zosasunthika zomwe zimapangidwa ndi alumina bauxite yapadera yapamwamba kapena emery, magnesia ndi graphite yosalala ngati chinthu chachikulu. Magnesia alumina carbon firebrick ili ndi mawonekedwe a kukana dzimbiri, kukana kwambiri komanso machitidwe abwino amakina pansi pa kutentha kwambiri, ndi zina zotero. Njerwa zosasunthika za Magnesia alumina carbon zimagwiritsidwa ntchito kwambiri mu ladle liner yolimba yachitsulo chosungunuka. Ndipo magnesia alumina carbon firebrick imagwiritsidwanso ntchito mu bafa yosungunuka ndi pansi pa ladle yopangidwa mosalekeza ndi phukusi lalikulu la tundish ndi lakunja la ng'anjo yoyeretsera likuwonjezeka.
Katundu wa Magnesia Alumina Carbon Bricks
- Kutsika kwa porosity komanso kutentha pang'ono,
- Kukana kutentha bwino,
- Mphamvu yayikulu yolimbana ndi dzimbiri,
- Kukana kukokoloka kwa nthaka, kukana kwambiri slag,
- Mphamvu yabwino kwambiri yolimbana ndi okosijeni komanso yoletsa kuchotsedwa kwa zinthu.
Ubwino wa Magnesia Alumina Carbon Bricks
Njerwa za Magnesia alumina carbon fire zili ndi anti-kukokoloka, anti-stripping, antioxidant komanso not sticky residues etc.. Njerwa za Magnesium alumina carbon fire zakhala zikugwiritsidwa ntchito kwambiri mu ndevu mu continuous casting ndipo mwanjira ina zachepetsa kusiyana kwa moyo wa ndevu zopitilira.
Njira Yopangira Njerwa za Magnesia Alumina Carbon
Magnesia alumina carbon block ndi zinthu zopangira zosaphika zokhala ndi bauxite yapadera
Magnesite kapena corundum ndi flake graphite, yomwe imadziwika ndi kutentha kwambiri ndi kaboni wambiri komanso kukana dzimbiri komanso zabwino zotsutsana ndi kuchotsedwa kwa zinthu, ilinso ndi
kutentha komwe kumapangidwa pogwiritsa ntchito spinel ndipo kunawonetsa mzere wotsalira wa chiŵerengero chachikulu cha kukula
ubwino, wakhala chitukuko chatsopano cha njerwa zapamwamba kwambiri.

Kugwiritsa Ntchito Njerwa za Magnesia Alumina Carbon
Njerwa za magnesium alumina carbon fire zimagwiritsidwa ntchito kwambiri mu ndevu mu continuous casting ndipo mwanjira ina zimathandiza kuchepetsa kusiyana kwa moyo wa ndevu zopitilira. Komanso magnesium alumina carbon firebrick ingagwiritsidwe ntchito m'malo otsatirawa:
- 1. Otembenuza, EAF, ng'anjo zoyeretsera,
- 2. Mzere wa slag ndi mzere wachitsulo wa ladle,
- 3. Wogwira ntchito pa ng'anjo yamagetsi,
- 4. Wosintha ng'anjo wosanjikiza ntchito,
- 5. Ng'anjo yamagetsi yamphamvu kwambiri, mkati mwake muli ndi ladle ndi kuyeretsa kunja kwa ng'anjo.
