The Technical Development of EAF Steelmaking has a history of about 100 years. Although always facing the challenges and competition of several other steelmaking methods, especially the impact of high-efficiency oxygen converter steelmaking, the proportion of steel production in electric arc furnace steel production in the world's total steel output continues to rise year by year. Electric arc furnace steelmaking relies on graphite electrodes to generate electric arc, which converts electric energy into thermal energy in the arc light. Steelmaking method of melting furnace charge and removing impurity components such as sulfur and phosphorus, and then adding required elements (such as carbon, nickel, manganese, etc.) to smelt various steels or alloys with different properties. Furnace temperature can be accurately controlled with electric energy heating, which produces less high-temperature exhaust gas, and the thermal efficiency of electric arc steelmaking fur...
