Perbandingan (Study Banding) Holding Time (Waktu Perbandingan) dengan Tanpa Holding Time pada Proses Fluxing di PT.Inalum Kuala Tanjung

Abstract

Holding time is the time to produce slag cast with the addition of flux in the oven, the treatment of the flow in theory, but is always in the field when the temperature is still high, can not be used. Results of treatment in flow is slag, slag produced approximately 30 to 40 Kg 200 Kg of metal slag. The calculations used in the calculation as determined by PT INALUM. On the data obtained in unit 0 to 30 minutes time of the acquisition slag 64%, at the time of 31 to 60 minutes of the unity of acquisition of the slag of 74.3%, and 61-90 minutes in a slag unit of time of acquisition of 75.4 per centthen every 1 ton of aluminum bars is a unit of acquisition of slag of ± 75%, so if the slag below 50%, then the metal must be recycling.
