Pengaruh Konsentrasi Feeding Alumina terhadap Produktivitas Aluminium Cair pada Tungku Reduksi di PT Inalum Kuala Tanjung

Abstract

In producing liquid Aluminum, Feeding Alumina is done by stove requirement with the read of voltage and resistant. One thing that can decrease the liquid Aluminum productivity is concentration of alumina (Al2O3) in stove. The ranges of Al2O3 concentration are among 2-4% called Demand Feeding. When Concentration of Al2O3 < 1% will generate the Anode Effect (AE). And if concentration of Al2O3 > 5% will yield sludge in stove base. Therefore, to optimal the liquid Aluminum productivity, Feeding Alumina must be really controlled.
