Leben sare oo aluminium ah ayaa lagu soo saaraa xulashada bauxite chamotte oo ah alaabta ceeriin ee ugu weyn, oo lagu shido 1450-1470 ° C iyadoo la raacayo nidaam horumarsan oo leh koontarool tayo adag leh. Lebenka Dabka ee Alumina Sare waxaa lagu soo saaraa aluminium ama walxo kale oo ceeriin ah oo ay ku jiraan maaddo aluminium sare ah iyada oo loo marayo qaabaynta iyo toogashada. sababtoo ah hantideeda dhexdhexaadka ah ee alumina refractory waxay iska caabin kartaa nabaad-guurka aashitada.
Geedi socodka lebenka sare ee aluminium
Ka dhex xulo oo shaandhee chamotte si aad u nadiifiso ka hor inta aanad jebin, taas oo hagaajin karta tayada lebenka aluminium ee sare. Sababtoo ah waxaa jira saamiga sare ee grog ee maaddooyinka oo gaari kara 90 ~ 95%. Dooro oo baadh deiroing ka hor inta aan la burburin.
Saddex Darajo oo Leben Aluminium Sare ah
Marka loo eego nuxurka kala duwan ee Al2O3, lebenka aluminium ee sarreeya waxaa loo kala saari karaa Saddex Fasalo oo Shiinaha ah.
Buundooyinka aluminiumka sare ee darajada 1aad waxay leeyihiin wax ka badan 75% Al2O3.
Fasalka 2-aad ee buundooyinka aluminiumka sare leh ayaa ka kooban 60 ~ 75% Al2O3.
Fasalka III Bricks Alumina Sare waxay leeyihiin 48 ~ 60% ka kooban Al2O3.
Astaamaha bulukeetiga Alumina Sare
Lebenka aluminiumka sare wuxuu leeyahay astaamo aad u wanaagsan sida waxqabadka heerkulka sare, daxalka weyn iyo iska caabbinta xirashada, cufnaanta bulk sare, maadada birta oo yar, iwm.

Codsiga bulukeetiga sare ee aluminium
Leben aluminium sare ah ayaa loo isticmaali karaa foornada qaraxa, shooladda qaraxa kulul, foornada koronto. sidoo kale lebenka dabka aluminium sare loo isticmaalo beeraha birta iyo birta, nonferrous, galaaska, sibidhka, ceramics, petrochemical, mashiinka, kuleyliyaha, warshadaha iftiinka, korontada, iyo warshadaha military iwm.
