Mabhora ealumina anodzivisa kusimba kwawo ane simba rakawanda, kuomarara kwakanyanya, kugona kukuru kwekukwesha, kukora kwehukuru, kushanda zvakanaka pakupisa kwakanyanya, kuramba ngura, kusvibiswa kushoma uye zvimwe zvinhu zvakanaka. Mabhora ealumina ave achishandiswa zvakanyanya mukupedzisa nekugadzirisa zvakadzama mhando dzakasiyana dzeceramic, enamel, girazi, makemikari nezvimwe zvinhu zvakaoma uye zvakakora.
Zvimiro zveAlumina Refractory Balls
- Kuramba Kupisa Kwakanyanya
- Kudzivirira Kupisa Kwakanaka
- Simba Repamusoro reMichina
- Hupenyu Hurefu hweBasa
Kuumbwa kweAlumina Refractory Balls
Mabhora eAlumina anogadziriswa neAL2O3, kaolin, synthetic aggregate, mullite crystal nezvimwe zvinhu. Zvinoenderana nenzira yekumonera nekudhinda, mabhora ealuminium anogadziriswa nearuminiyamu ane mabhenefiti esimba rakawanda, anodzivirira kupisa zvakanyanya, anotsiva uye anochenesa zviri nyore, anogara kwenguva refu zvichingodaro.
Maitiro eAlumina Refractory Balls
Kuti pagadzirwe mabhora e-alumina refractory, electrode inoiswa pasi pe graphite crucible, uye arc inogona kutanga nekuwedzera huwandu hwakati hwe industrial alumina powder. Inoshanda 1.0kA, voltage 80 ~ 100V. Mushure mekurova, sezvo Al2O3 yakanyunguduka, ichitakura zvishoma nezvishoma, kusvika mvura yacho yazadzwa ne graphite crucible, tembiricha yemvura yacho i2200 ~ 2300 ℃. Mushure meizvozvo, crucible inodururwa uye mhinduro inobuda.

Kushandiswa kweAlumina Refractory Balls
Mabhora eAlumina anoshandiswa zvakanyanya mukupedzisa nekugadzirisa zvakadzama mhando dzakasiyana dzeceramic, enamel, girazi, makemikari nezvimwe zvinhu zvakakomba uye zvakaoma. Kunyanya mabhora ealuminium akakodzera michina yekuparadzanisa mhepo inokonzera kupisa uye simbi blast furnace gas heating furnace sechinozadza chekuchengetedza kupisa.
