Abstract: Measures of CO2 reduction are analyzed with actuality of CO2 emission from iron and steel making in China, such as, increasing the production of steel scrap-EAF process, improving the quality of iron, improving the ratio of non-fossil energy, employing low carbon technologies, enlarging scale of equipment and using energy-efficient technologies. There are many technologies of energy conservation and emission reduction in iron and steel industry such as coke dry quenching, coal moisture control, gas recycling, waste heat and energy recycling and low pressure saturated steam power technology. CO2 emission will reduce 290 million tons through the application of energy-saving technologies. In short-term and long-term aspects, the prospect of CO2 reduction in domestic iron and steel industry is analyzed.

Key words: iron and steel making industry, CO2, reduction, production process, energy-efficient technology, low carbon steel-making
