The stability of aluminum reduction cell is the fundamental guarantee for high efficiency and low energy consumption of aluminum electrolytic production. Temperature stability is an essential feature of and basic guarantee for the stability of a cell. In this paper, based on industrial tests on the 300kA industrial cells and a large number of data mining research on it, some regularities of periodic fluctuation of the cell temperature are found along with the feeding circles and the seasons. The relationship among cell temperature, feeding cycles and local air temperature has been studied. In the end, some suggestions for primary aluminum production are provided to improve daily temperature measurement, alumina feeding control strategies and energy balance according to local meteorological data in different region.
