Industrial production of iron and steel enterprises simple detailed introduction, 2012-2016, the International Paint Brush Iron and Steel Association members of the average ton of steel comprehensive energy consumption index value in the overall increase in the development trend, and in China's electric furnace steel share and Europe and the United States, Japan and South Korea and other traditional steel big country comparison, the proportion is more serious slightly lower, As a result, there is a great difference in structural energy use between the average value of comprehensive energy consumption per ton of steel in China and the average value of comprehensive energy consumption per ton of steel in overseas countries. From the perspective of the national production process in 2017, the share of electric furnace steel in Europe, the United States, Indonesia and other countries in Asia is about 60%, the share of other countries in the middle of 20 ~ 30%, only in China is only about 9%.

According to the trend analysis of comprehensive energy consumption per ton of steel in China's steel industry, in 2017, the comprehensive energy consumption per ton of steel in key large, medium and small steel industries in China decreased to 570.8kgce/t, which decreased by 2.6% compared with the same period. The crude steel output of paint brushes increased by 2.9% in 2016, and the old energy energy increased by about 0.3%. Due to the harm of technical development and management improvement, the energy consumption index value per ton of steel in China has been reduced to a certain extent. Among them, compared with 2016, the key production and manufacturing processes all showed a downward trend. The energy consumption of the coking plant process decreased slightly by 0.04%, the energy consumption of the calcination process decreased by 2.77%, the energy consumption of the steelmaking process decreased by 1.48%, the energy consumption of the converter steelmaking process increased by 0.03%, and the energy consumption of the electric furnace ironmaking process decreased by 0.06%. The energy consumption of steel rolling process increased by 0.03%.
