Anode effect elimination by subsonic and sonic vibrations

Abstract

The only method so far used industrially to produce primary aluminum is the combination of the Bayer process with the Hall-Heroult process. The production process of aluminum which was patented by Charles Martin Hall and Paul Louis Toussaint Heroult in 1886, has long been important in our daily lives and that importance is likely to increase year by year. In this study, different subsonic and sonic vibrations, which were obtained from a 0.30 kW, 1,400 rpm three-phase motor, also a 0.55 kW, 2,800 rpm three-phase motor and 0.75 kW frequency converter, were applied to a laboratory-type aluminum electrolysis cell and the possibility of eliminating the anode effect was investigated.
