A method of impregnation-surface alloying is proposed to form an oxidation resistant compound protective layer with good electrical conductivity on the surface of graphite electrode to reduce the side oxide consumption of the graphite electrode in EAF process. In this paper, the basic process of the method is introduced. The formation mechanism of the composite protective layer is studied. The corresponding dynamic mathematical model is established, and the oxidation mechanism is discussed preliminarily.
