Njerwa zapamwamba za alumina (Kalasi I, II, III)

Njerwa yapamwamba ya alumina ndi chinthu chosalowerera ndale, chomwe chimakhala ndi kukana kwa dzimbiri ku asidi ndi zamchere zamchere, ndipo chimadziwika ndi mphamvu zopondereza kwambiri, kukana kukokoloka, kukana kulowa mkati, komanso kutentha koyambira komwe kumafewetsa kwambiri.

High aluminiyamu refractory njerwa
(Kalasi I, II, III)

Mphamvu yopondereza kwambiri, kutentha kwakukulu kofewetsa, anti peeling

Njerwa yapamwamba ya alumina imapangidwa ndi aluminiyamu yayikulu kwambiri ngati chinthu chachikulu chopangira polimbitsa kuphatikizana kwa matrix ndi tinthu ting'onoting'ono, ndikuwonjezera binder yophatikizika, ndi kutentha kwambiri.Iwo ali makhalidwe a kukana kuthamanga, mkulu katundu kufewetsa kutentha, odana peeling, etc. Ndi abwino kwambiri akalowa wa CFB boilers ndi kilns zina matenthedwe.

Good voliyumu bata pa kutentha kwambiri.Mkulu wamakina mphamvu.Zabwino kuvala kukana.Tishu ndi wandiweyani.Low porosity.Kukana bwino kwa slag.Iron oxide imakhala yochepa.

Zimaphatikizapo njerwa zazikulu za alumina, njerwa zadongo, njerwa za corundum, njerwa za silicon carbide ndi njerwa za carbon.Mu ng'anjo yophulika, chifukwa cha zosiyana zogwirira ntchito za gawo lililonse, kusinthasintha kwa kutentha kumakhala kwakukulu, ndipo kutenthedwa kwa kutentha komwe kumayendetsedwa ndi gawo lililonse kumakhala kosiyana, kotero kuti kukana kofunikira ndi gawo lililonse kumasiyananso.
