Development and application of SAMI’s low voltage energy-saving technology

Abstract

In this paper one low voltage energy-saving technology for aluminum reduction cell is developed by SAMI, this technology can largely reduce horizontal current in the metal pad and improve the MHD stability of the cell. Some industrial testing results of this technology by SAMI and its application on different type cells in Chinese smelter are finally presented to illustrate how their contributions is to make D.C. power consumption close to 12000 kWh/t-Al without current efficiency loss compare to the prior technology.
