Abstract equipments growing larger in scale; longer life of blast furnaces and converters; coalpowder injection for blast furnace, slag splash technology for converter, and the high ratio of continuous casting for steelmaking process; comprehensive energy consumption and productivity in large and medium steel plants getting close or reaching the world’s advanced level; the output of plates and tubes making up almost 50% of the total products; China is becoming the largest country in the production and consumption of stainless steel.China’s iron and steel industry is constrained by resources and environment. To build up a resourcesaving and environmentfriendly steel industry, China has to form an industrial chain of circulareconomy with steel plants as its core, which carries out three functions of producing high quality steel products, highefficient energy transformation, and utilizing wastes of society.Despite of the rapid expanding in its producing capacity, China’s iron and steel industry has made considerable progress in increasing the strength of steel for construction and fastenings, developing steel for automobiles, and upgrading the performance of pipeline steel, bearing steel, and die steel.
