The working principle of EAF

EAF steelmaking uses electric energy as the main heat source and uses three-phase alternating current or direct current. An electric arc is directly generated between the charge and the electrode, and the charge is melted at a high temperature by the electric arc, and then oxidizer, slag-forming agent, ferroalloy, etc. are added to remove inclusions. The chemical composition and temperature of the molten steel are adjusted to the specified values and then injected into the ladle. Since the 1980s, EAF have developed in the direction of large-scale, ultra-high power, direct current, continuity and automation, and the world's EAF steelmaking production technology has developed more rapidly.
