Wararka - Lebenka Alumina Sare ee Foornada Qarxa

Lebenka sare ee alumina ee foornooyinka qaraxa waxay ka samaysan yihiin bauxite-heer sare sida alaabta ceeriin ee ugu weyn, kuwaas oo la dubay, la riixay, la qalajiyey oo lagu shiday heerkul sare.Waa alaabo dib u celin ah oo loo isticmaalo dahaarka foornooyinka qaraxa.

2. Aaway lebenkii sare ee aluminium ee loo isticmaalo foornooyinka qaraxa?

Leben aluminium sare ah ayaa lagu dhisay shafka foornada ee foornada qaraxa.Usha foornada waxay ku taallaa qaybta sare ee foornada qaraxa.Dhexroorkeedu si tartiib tartiib ah ayuu kor ilaa hoos ugu fidayaa si uu ula qabsado balaadhinta kulaylka ee kharashka oo uu yareeyo khilaafka gidaarka foornada ee kharashka.Jirka foornada ayaa ku jira foornada qaraxa.50% -60% dhererka waxtarka leh.In deegaanka this, dahaarka foornada u baahan tahay si ay u buuxiyaan shuruudahan oo kale, iyo sifooyinka leben alumina sare waa refractoriness sare, heerkulka jilcin sare hoos load, caabbinta acid, caabbinta alkali, iska caabin xoog leh nabaad guurka slag, iyo xirashada wanaagsan iska caabin ah.Waa la qancin karaa, sidaas darteed waxay aad ugu habboon tahay jirka foornada qaraxa in lagu dhejiyo leben aluminium sare ah.

Kuwa kore waa hordhaca lebenka aluminiumka sare ee foornooyinka qarxa.Deegaanka dahaarka leh ee foornada qaraxu waa mid adag waxaana jira noocyo badan oo agabka celinaya oo la isticmaalo.Lebenka aluminium sare ayaa ka mid ah.Waxaa jira 3-5 sifooyin oo leben aluminium sare loo isticmaalo.Lebenka aluminiumka sare ee Robert waxaa loo isticmaali karaa noocyo kala duwan oo kilns ah.Haddii loo baahdo, fadlan nala soo xiriir.
