Bulo na Alumina Ccarbon wani nau'in kayan haɗin carbon ne wanda aka yi da kayan alumina da carbon, wani lokacin ana haɗa shi da silicon carbide, silicon na ƙarfe da sauran haɗin organic, kamar resin. Nau'in tubalin wutar carbon na alumina yana da tubalin zamiya na aluminum carbonaceous, tubalin nozzle da aka ƙera, tubalin carbon mai jure wa alkali da tubalin carbon na aluminum. Siffofin tubalin carbon mai jure wa alumina sune juriyar tsatsa, kwanciyar hankali mai kyau na zafi, ƙarfi mai yawa da kuma yawan zafin jiki.
Tsarin Bulo na Alumina Carbon
Ana yin tubalin carbon na Alumina ta hanyar amfani da musamman bauxite clinker, corundum, graphite da mid alumina a matsayin manyan kayan albarkatun ƙasa, tare da nau'ikan ƙarin foda mai kyau da yawa. Tsarin tubalin carbon mai hana carbon na alumina shine ƙara aluminum oxide, carbonaceous, silicon foda da ƙananan adadin wasu kayan albarkatun ƙasa zuwa kayan albarkatun ƙasa, sannan a yi amfani da kwalta, binder, resin ko bayan sinadaran, a haɗa, a matse, a kusa da 1300 ℃ sintering don rage yanayi.
Siffofin Bulo na Carbon Alumina
- juriya mai ƙarfi ta tsatsa,
- kwanciyar hankali mai kyau na girgizar thermal,
- babban ƙarfi,
- babban ƙarfin lantarki na thermal.
Rarraba Bulo na Carbon na Alumina
Ana iya raba tubalin carbon na alumina zuwa rukuni biyu, tubalin carbon na magnesia alumina da tubalin carbon na alumina magnesia.
Bulo na ƙarfe na Magnesia alumina, wanda ke da babban magnesite, corundum, spinel da graphite a matsayin kayan masarufi, waɗanda aka haɗa su da resin, suna da kyakkyawan juriya ga slag.
Bulo na carbon na Alumina magnesia, wanda ke da babban matakin bauxite, corundum, spinel, high quality magnesite da graphite a matsayin kayan albarkatu, waɗanda aka haɗa su da resin, suna da alaƙa da yashewa da juriyar tsatsa, da juriyar spouting.
