EAF process compared with the BOF process, has the following characteristics: ?EAF process investment, small footprint, short construction period; ?resources: As the national economy development, iron ore, coking coal and other resources will become increasingly scarce, and waste Steel Resources will continue to accumulate, it has an advantage in the long run EAF process; ?environmental issues: EAF process generated CO2, NOx, SOx and other harmful gases in high furnace - BOF process less; ?energy issues: scrap - electric - steel and blast furnace - converter - steel two processes compared to the total energy consumption is only a short length of the process flow of 50%. It is predicted that China will end in 2008 and 2009 middle stage of industrialization, steel production and consumption will be the turning point, after which the growth rate of steel will rapidly slowed down significantly. When industrialization after 2020, steel consumption will reach the peak, after which resources will be more and more scrap, and scrap-based EAF steel to the cost advantage of resources will become increasingly prominent.
