Penentuan Nilai Reaktivity Residu (Rr) O2 untuk Pengendalian Kualitas Anoda di PT Inalum Kuala Tanjung

Abstract

One of the factors effecting the quality of anode is Residual Reactivity (RR) of O2. Residual Reactivity (RR) of O2 is the parameter of the amount of carbon anode left after the reaction of O2. The value of Residual Reaktivity (RR) of O2 obtained must be over 88 %, because if the Residual Reactivity (RR) of O2 is below 88 %, the anode is more suscaptible to oxidation and will yield carbon dust so that the anode is easier crack and the use of anode is not optimum. For the observation obtained the value Residual Reactivity (RR) of O2 are 90,75 %, 91,95 %, 90,76 %, 89,53 %. This is show that the anode produced still the supply standardized have the certained must be over 88 %.
