Magnesite alumina carbon njerwa ndi mtundu wa njerwa refractory amene amapangidwa wapadera kalasi mkulu aluminiyamu bauxite kapena emery, magnesia ndi flaky graphite monga mfundo yaikulu. Magnesia alumina carbon firebrick ali ndi makhalidwe a mkulu dzimbiri kukana, mkulu refractoriness ndi khalidwe makina abwino pa kutentha kwambiri, etc. Magnesia alumina carbon refractory njerwa chimagwiritsidwa ntchito okhwima chitsulo chosungunula ladle liner. Komanso magnesia alumina carbon firebrick amagwiritsidwa ntchito mu bafa yosungunuka ndi ladle pansi mosalekeza kuponyera lalikulu tundish ndi kunja ng'anjo kuyenga phukusi likuchulukirachulukira.
Katundu wa Magnesia Alumina Carbon Njerwa
- Kutsika kowoneka bwino kwa porosity ndi kutentha kochepa,
- Kukana kwabwino kwa kutentha kwa kutentha,
- High mphamvu zabwino dzimbiri kukana,
- Kukana kukokoloka kwabwino, kukana kwambiri kwa slag,
- Zabwino kwambiri za anti-oxidation komanso anti-stripping.
Ubwino wa Magnesia Alumina Carbon Njerwa
Magnesia alumina carbon fire njerwa ndi anti kukokoloka, anti stripping, antioxidant ndi notsticky zotsalira etc.
Njira Yopangira Magnesia Alumina Carbon Njerwa
Magnesia alumina carbon block ndi refractory yaiwisi ndi wapadera kalasi bauxite
magnesite kapena corundum ndi flake graphite, yomwe imadziwika ndi kutentha kwambiri ndi mpweya wambiri wokhala ndi kukana kwa dzimbiri komanso ma anti stripping, ilinso ndi
kutentha komwe kumapangidwa ndi ntchito ya spinel ndikuwonetsa mzere wotsalira wa chiŵerengero chokulirakulira
ubwino, wakhala chitukuko chatsopano cha mkulu khalidwe akalowa njerwa.

Kugwiritsa ntchito njerwa za Magnesia Alumina Carbon
Magnesium alumina carbon fire njerwa amagwiritsidwa ntchito kwambiri mu ladle poponya mosalekeza ndipo pang'onopang'ono kumachepetsa kutsika kosalekeza kosalekeza kwa moyo wa ladle. Komanso magnesium alumina carbon firebrick angagwiritsidwe ntchito malo otsatirawa:
- 1. Converters, EAF, kuyenga ng'anjo,
- 2. Mzere wa slag ndi mzere wachitsulo wa ladle,
- 3.Electric arc ng'anjo yogwira ntchito,
- 4.Converter ng'anjo ntchito wosanjikiza,
- 5.Mng'anjo yamagetsi yamagetsi, kuyatsa kwa ladle ndi kuyenga kunja kwa ng'anjo.
