Kubadaha refractory alumina waxay leeyihiin tayada wanaagsan ee xoogga sare, qallafsanaanta sare, awoodda abrasion aad u fiican, cufnaanta cufnaanta, waxqabadka heerkulka sare, caabbinta daxalka, wasakh yar iyo sifooyin kale oo aad u fiican. kubadaha alumina ayaa si weyn loogu isticmaalay dhamaystirka iyo farsamaynta qoto dheer ee noocyada kala duwan ee dhoobada, dhaldhalaalka, dhalooyinka, kiimikooyinka iyo walxaha kale ee dhumuc iyo adag.
Astaamaha Kubadaha Refractory Alumina
- Cadaadiska Heerkulka Sare
- Iska caabbinta kulaylka Wacan
- Xoogga Farsamada Sare
- Nolosha Adeegga Dheer
Halabuurka Kubadaha Refractory Alumina
Kubadaha alumina-ka-soo-celinta waxay ka samaysan yihiin AL2O3, kaolin, wadarta guud ee synthetic, crystal mullite iyo walxo kale. Sida ku cad duubista iyo habka qaabaynta saxaafadda. Kubadaha aluminiumku waxay leeyihiin faa'iidooyinka xoogga sare, caabbinta kuleylka kuleylka wanaagsan, beddelka habboon iyo nadiifinta, nolosha adeegga dheer iyo wixii la mid ah.
Habka Kubadaha Refractory Alumina
Si loo sameeyo kubbadaha refractory alumina, electrode ayaa la dhigayaa xagga hoose ee graphite crucible, iyo arc waxaa lagu bilaabi karaa iyada oo lagu daro qadar gaar ah oo ah budada aluminium warshadaha. Shaqeynaya 1.0kA hadda, danab 80 ~ 100V. Ka dib markii garaacid, sida Al2O3 dhalaalay, loading si tartiib tartiib ah, ilaa dareeraha walxaha ka buuxsamay crucible graphite, heerkulka dareere wax ah waa 2200 ~ 2300 ℃. Taas ka dib, crucible waa la shubay iyo xalka soo baxa.
