Energy Conservation and Emissions Reduction in Iron and Steel Industry

With the increasingly exhausting mineral resources and deteriorating environmental pollution, current steel making process structure must be optimized and new Iron making technology should be developed in China's iron and steel industry to save energy and reduce emissions. The paper presents facing dilemma of iron and steel enterprises, some effective measures to cope with the problems, and especially new Ironmaking-HIsmelt, which is relatively green technology as compared to the blast furnaces. The predominance of smelting high-phosphorus iron ore and ilmenite by HIsmelt technology, which is reserved vastly in China, is analyzed selectively in the paper. Through theoretical analysis and experimental verification, conclusion could be drawn that HIsmelt technology is attractive to smelting high-phosphorus iron ore and ilmenite, which helps exploit these lean iron ore mines.
