Alumina Ccarbon tubali wani nau'i ne na kayan haɗin gwiwar carbon wanda aka yi da alumina da kayan carbon, wani lokaci ana haɗe shi da silicon carbide, silicon karfe da sauran abubuwan haɗin gwiwa, kamar guduro. alumina carbon wuta tubali iri-iri yana da aluminum carbonaceous slide tubali, jefa bututun bututun ƙarfe, alkali resistant aluminum tubalin carbon da fashewa tanderu aluminum tubalin carbon. alumina carbon refractory tubali fasali ne mai karfi lalata juriya, mai kyau thermal girgiza kwanciyar hankali, high ƙarfi da kuma high thermal watsin.
Alumina Carbon Brick Tsari
Alumina carbon carbon ana yin bulo ta hanyar ɗaukar nau'ikan bauxite clinker na musamman, corundum, graphite da tsakiyar alumina azaman babban kayan albarkatun ƙasa, haɗe da nau'ikan abubuwan ƙarar foda mai kyau da yawa. Tsari na alumina carbon refractory tubali yana ƙara da Aluminum oxide, carbonaceous, silicon foda kayan da kuma kananan adadin sauran albarkatun kasa zuwa albarkatun kasa, sa'an nan yi amfani da kwalta, dauri, guduro ko bayan sinadaran, hadawa, latsa kafa, a kusa da 1300 ℃ sintering. a rage yanayi.
Siffofin Brick Carbon Alumina
- juriya mai ƙarfi,
- kyau thermal shock kwanciyar hankali,
- high ƙarfi,
- high thermal watsin.
Rarraba Brick Carbon Alumina
Alumina carbon tubali za a iya raba biyu classification, Magnesia alumina carbon tubali da alumina magnesia carbon tubali.
Magnesia alumina carbon tubali, tare da high sa magnesite, corundum, spinel da graphite matsayin albarkatun kasa, bonded da guduro, suna halin da kyau slag juriya.
Alumina magnesia carbon tubali, tare da high sa bauxite, corundum, spinel, high tsarki magnesite da graphite matsayin albarkatun kasa, bonded da guduro, suna halin yashwa da lalata juriya, spalling juriya.
