Heerkulka shaqada iyo isticmaalka lebenka dabka ee fudud ee dahaarka leh ee caadiga ah 2

3. Leben kubbad godan oo Alumina ah

Waxyaabaha ugu muhiimsan ee ceeriinkeeda waa kubbadaha godan ee alumina iyo budada oksaydhka aluminiumka, oo lagu daray xidhmooyin kale. Waxaana lagu shidaa heerkul sare oo ah 1750 darajo Celsius. Waxay ka tirsan tahay walxaha keydiya tamarta iyo dahaarka heerkulka aadka u sarreeya.
Aad bay u deggan tahay in lagu isticmaalo jawi kala duwan. Gaar ahaan ku habboon in lagu isticmaalo foornada heerkulka sare leh ee 1800 ℃. Kubbadaha godka ah waxaa loo isticmaali karaa heerkul sare iyo heer aad u sarreeya.Buuxiyaasha dahaarka heerkulka, isku-darka fudud ee loogu talagalay shubka heerkulka sare leh ee aan heerkulka sare lahayn, kuwa heerkulka sare leh ee la tuuri karo, iwm. Iyada oo ku saleysan tilmaamayaasha jireed iyo kuwa kiimikada, lebenka kubbadda godan ee aluminiumka ayaa si weyn loogu isticmaalaa foornada heerkulka sare leh iyo kuwa aadka u sarreeya sida gaasiyayaasha warshadaha batroolka, foornooyinka falcelinta warshadaha madow ee kaarboonka, foornooyinka soo saarista warshadaha birta, iwm., waxayna gaareen saameyn aad u wanaagsan oo tamar badbaadin ah.
