Cov Khoom Siv Alumina Refractory Balls
Cov pob alumina refractory yog ua los ntawm AL2O3, kaolin, cov khoom sib xyaw ua ke, mullite siv lead ua thiab lwm yam khoom siv. Raws li txoj kev dov thiab nias molding, cov pob aluminium refractory muaj qhov zoo ntawm lub zog siab, tiv taus thermal shock zoo, yooj yim hloov thiab ntxuav, lub neej ua haujlwm ntev thiab lwm yam.
Cov Txheej Txheem Alumina Refractory Balls
Yuav kom ua tau cov pob alumina refractory, lub electrode muab tso rau hauv qab ntawm lub graphite crucible, thiab lub arc tuaj yeem pib los ntawm kev ntxiv qee qhov nyiaj ntawm cov hmoov alumina industrial. Kev ua haujlwm tam sim no 1.0kA, voltage 80 ~ 100V. Tom qab ntaus, raws li Al2O3 yaj, thauj khoom maj mam, kom txog thaum cov kua khoom puv nrog graphite crucible, cov kua khoom kub yog 2200 ~ 2300 ℃. Tom qab ntawd, lub crucible raug nchuav tawm thiab cov tshuaj ntws tawm.
