Kufotokozera Kwachidule:

Njerwa ya High Alumina, yomwe imadziwikanso kuti njerwa yamoto ya aluminiyamu yayikulu, yomwe imapangidwa ndi bauxite ndi zinthu zina zopangira zokhala ndi aluminiyamu yapamwamba pambuyo pakuumba ndi kupukuta. High aluminiyanje njerwa ndi mtundu wa zinthu kaŵirikaŵiri refractory zogulitsa mu RS Company, amene ali katundu refractoriness mkulu, mphamvu mkulu, asidi, wabwino matenthedwe bata ndi zina zotero. Njerwa ya High Alumina imagwiritsidwa ntchito kwambiri mu ng'anjo yophulika, chitofu choyaka moto, ng'anjo yamagetsi.

Njerwa yapamwamba ya alumina imapangidwa ndi bauxite chamotte yosankhidwa ngati zopangira zazikulu, zowotchedwa pa 1450-1470 ° C ndi njira zapamwamba zowongolera bwino kwambiri. Njerwa Zamoto Zapamwamba za Alumina zimapangidwa ndi aluminiyamu kapena zida zina zokhala ndi aluminiyamu wapamwamba kwambiri kudzera mukuumba ndi kuwombera. chifukwa cha ndale refractory katundu aluminiyamu refractory akhoza kukana asidi slag kukokoloka kukana.

High Alumina Njerwa Njira

Pitani pa Select and sieve chamotte for deironing musanathyole, zomwe zingapangitse kuti njerwa za alumina zikhale zabwino kwambiri. Chifukwa pali gawo lalikulu la grog mu zosakaniza zomwe zimatha kufika 90 ~ 95%. Sankhani ndi kuwunika deironing pamaso grog wosweka.

Magulu Atatu a Brick Alumina Wapamwamba

Malinga ndi zomwe zili mu Al2O3, njerwa zapamwamba za alumina zitha kugawidwa m'magulu atatu ku China.

Njerwa za Grade I High Alumina zili ndi zoposa 75% za Al2O3.

Njerwa za Grade II High Alumina zili ndi 60 ~ 75% Al2O3 zokhutira.

Njerwa za Grade III High Alumina zili ndi 48 ~ 60% Al2O3 zokhutira.

Mawonekedwe a High Alumina Brick

Njerwa zapamwamba za alumina zimakhala ndi zinthu zabwino monga kutentha kwapamwamba, dzimbiri komanso kukana kuvala, kachulukidwe kachulukidwe, chitsulo chochepa, ndi zina zambiri.
