Alumina refractory npas muaj qhov zoo ntawm lub zog siab, siab hardness, muaj peev xwm ua kom zoo zoo, tuab tuab, kev ua haujlwm kub, kev tiv thaiv corrosion, muaj kuab paug tsawg thiab lwm yam khoom zoo heev. alumina pob tau siv dav hauv kev ua tiav thiab sib sib zog nqus ua ntau hom ceramic, enamel, iav, tshuaj thiab lwm yam ntaub ntawv tuab thiab tawv.
Cov khoom ntawm Alumina Refractory Balls
- Kub Kub Resistance
- Kev kub siab zoo
- Siab Mechanical Strength
- Lub neej ua haujlwm ntev
Kev sib xyaw ntawm Alumina Refractory Balls
Alumina refractory npas yog ua los ntawm AL2O3, kaolin, hluavtaws aggregate, mullite siv lead ua thiab lwm yam ntaub ntawv. Raws li cov dov thiab cov xovxwm molding txoj kev. aluminium refractory npas muaj qhov zoo ntawm lub zog siab, zoo thermal poob siab tsis kam, yooj yim hloov thiab tu, lub neej ua haujlwm ntev thiab lwm yam.
Alumina Refractory Balls Txheej txheem
Txhawm rau ua cov pob alumina refractory, cov electrode tau muab tso rau hauv qab ntawm graphite crucible, thiab cov arc tuaj yeem pib los ntawm kev ntxiv qee yam ntawm cov hmoov alumina hmoov. Kev khiav hauj lwm tam sim no 1.0kA, voltage 80 ~ 100V.Tom qab tawm tsam, raws li Al2O3 molten, loading maj mam, kom txog rau thaum cov khoom ua kua uas muaj graphite crucible, cov khoom ua kua kub yog 2200 ~ 2300 ℃.Tom qab ntawd, lub crucible yog poured tawm thiab cov tshuaj. ntws tawm.
