Alumina refractory mabhora ane mhando yakanaka yesimba repamusoro, kuomarara kwepamusoro, kugona kweabrasion kwakanakisa, kusimba kwehuwandu hwakawanda, kuita tembiricha yepamusoro, kuramba kwecorrosion, kusvibiswa kushoma uye zvimwe zvinhu zvakanakisa. mabhora ealuminium akashandiswa zvakanyanya mukupedzisa nekudzika kugadzirisa marudzi akasiyana eceramic, enamel, girazi, makemikari nezvimwe zvinhu zvakakora uye zvakaoma.
Alumina refractory mabhora anogadzirwa neAL2O3, kaolin, synthetic aggregate, mullite crystal nezvimwe zvinhu. Zvinoenderana nekukungurusa uye kuumbwa kwedhinda nzira. aluminium refractory mabhora ane zvakanakira kusimba kwepamusoro, yakanaka yekupisa kuvhundutsa kuramba, nyore kutsiva uye kuchenesa, hupenyu hurefu hwebasa uye zvichingodaro.
Kuti ugadzire bhora realuminium refractory, electrode inoiswa pazasi pe graphite crucible, uye arc inogona kutangwa nekuwedzera imwe huwandu hweindasitiri alumina poda. Kushanda ikozvino 1.0kA, voltage 80 ~ 100V. Mushure mokurova, seAl2O3 yakanyungudutswa, ichitakura zvishoma nezvishoma, kusvikira mvura yemvura izere negraphite crucible, tembiricha yemvura yezvinhu ndeye 2200 ~ 2300 ℃. Mushure mezvo, crucible inodururwa kunze uye mhinduro. inoyerera ichibuda.
