'Five Cycle Control (FCC)' technology for aluminium reduction cells in China

The advanced multivariate process parameters intelligence control (MPPIC) technology, developed by CHALIECO GAMI, had been used in many large domestic and abroad greenfield built or modernized smelters. In this paper, the new concepts and development contents with MPPIC technology named 'Five Cycle Control'(FCC) technology will be discussed. The successful application of this new technology, resulting in significantly higher current efficiency and reduced energy consumption in several pilot and section's cells of two large domestic smelters, will also be discussed. The original MPPIC technology is currently being upgraded toward FCC technology.
