Process automatization and intellectuality is becoming an important strategy when traditional electrolytic aluminum of China does its best to catch up with the world advanced level. With mechanization and automatization widely applied in pot controller, multi-function Crane, anode production and assembly and so on, the improvement of process on comprehensive properties and intellectuality also becomes a new development trend for large aluminum electrolysis enterprises in China. In this paper, researches and developments in recent years, which are concerned on automatization and intellect diagnosis of electrolytic aluminum production in China, are discussed from three aspects. One is control optimization in PTM, the other two are on-line monitoring on multi-physical field and diagnosis on cell status, respectively. The great significance of them in the new industrial revolution of aluminum electrolysis field in China is also given.
