Abstract:The technologies of neural network control and fuzzy expert control were used in the large-power EAF intelligent automatic control system， which realizes two closed loops control of three phase current and temperature of EAF，and assures three phase current equilibrium and temperature stabilization. The system was running in Shaoguan Smelter， which has gotten better control effect and economical benefit in fact.
Key words: EAF； fuzzy expert； neural network
