Njerwa ya Alumina Ccarbon ndi mtundu wa zinthu zopangira kaboni zomwe zimapangidwa ndi alumina ndi zida za kaboni, nthawi zina zimasakanizidwa ndi silicon carbide, silicon yachitsulo ndi zomangira zina za organic, monga utomoni. Njerwa za alumina kaboni zoyaka moto zili ndi njerwa za aluminiyamu zokhala ndi slide, njerwa zoponyedwa, njerwa za aluminiyamu zosagwirizana ndi alkali komanso njerwa yoyaka moto ya aluminiyamu ya carbon. mawonekedwe a njerwa za alumina carbon refractory ndizolimba kukana dzimbiri, kukhazikika kwamphamvu kwamafuta, mphamvu yayikulu komanso kutenthetsa kwambiri.
Njira ya Njerwa ya Alumina Carbon
Njerwa ya kaboni ya Alumina imapangidwa ndikugwiritsa ntchito makina apadera a bauxite clinker, corundum, graphite ndi alumina yapakatikati ngati zida zazikulu zopangira, kuphatikiza mitundu ingapo ya zowonjezera ufa wapamwamba kwambiri. Njira ya alumina carbon refractory njerwa ndikuwonjezera Aluminiyamu okusayidi, carbonaceous, silicon ufa zipangizo ndi pang'ono zipangizo zina zopangira, ndiye ntchito phula, binder, utomoni kapena pambuyo zosakaniza, kusakaniza, kukanikiza kupanga, kuzungulira 1300 ℃ sintering. mu kuchepetsa mpweya.
Mawonekedwe a Alumina Carbon Brick
- kukana kwamphamvu kwa dzimbiri,
- kukhazikika kwamphamvu kwamafuta,
- mwayi waukulu,
- mkulu matenthedwe madutsidwe.
Gulu la Alumina Carbon Brick
Alumina carbon njerwa akhoza kugawidwa m'magulu awiri, magnesia alumina mpweya njerwa ndi alumina magnesia mpweya njerwa.
Magnesia alumina carbon njerwa, ndi mkulu kalasi magnesite, corundum, spinel ndi graphite monga zopangira, womangidwa ndi utomoni, imadziwika ndi kukana bwino slag.
Alumina magnesia carbon njerwa, ndi mkulu kalasi bauxite, corundum, spinel, mkulu chiyero magnesite ndi graphite monga zopangira, womangidwa ndi utomoni, yodziwika ndi kukokoloka ndi dzimbiri kukana, spalling kukana.

Alumina Carbon Brick Application
Njerwa ya kaboni ya Alumina imagwiritsidwa ntchito poyala bosh, stack ndi kuziziritsa khoma la ng'anjo yophulika. Magnesia alumina carbon njerwa makamaka ntchito ladle chapamwamba ndi m'munsi slag mzere. Alumina magnesia carbon njerwa makamaka ntchito ladle slag akalowa ndi pansi.
