Technical Development of EAF Steelmaking - Graphite Electrode Manufacturer

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 furnaces is higher than that of converters.

In the 1980s, continuous casting was widely popularized in electric furnace steel production, and gradually formed an energy-saving production process of "steel preheating-electric arc furnace melting-outside furnace refining-continuous ingot-continuous rolling". The electric arc furnace has become a rapid equipment for making steel mainly from scrap steel.

In the early 1990s, steel produced by electric arc furnaces around the world accounted for about one third of the total steel output. In some countries, steelmaking is mainly based on electric arc furnaces, such as Italy. The proportion of steel produced by electric furnace smelting is as high as 70% or more.
