Among all sectors of china's national economy, the iron and steel industry is a major energy consumer. In recent years, the proportion of the country's industrial energy consumption has increased from 12188% in 1995 to 15178% in 2002, and it is increasing year by year.compared with the increasing trend of energy use in iron and steel industry, the energy shortage in china is becoming more and more obvious.to cope with the energy shortage, china's iron and steel industry should first take a series of energy ful measures from the aspects of management and technology, effectively save energy and reduce consumption, so as to ensure the normal development of the iron and steel industry.the energy-saving work of china's steel industry has experienced 20 ~ 30 years of development. The comprehensive energy consumption per ton of steel (the average of the whole industry) decreased from 21040tce in 1980 to 01770tce in 2003, with a decline rate of 62%. However, because many advanced energy-saving technologies have not been promoted on a large scale, the energy consumption per ton of steel is still 10% ~ 20% higher than the advanced level abroad.
