中国钢铁工业节能成效显著
In recent years, as an important pillar industry for the development of the national economy, the iron and steel industry has actively implemented Xi Jinping's ecological civilization thought, and has made important contributions to promoting energy conservation and emission reduction and green and low-carbon development in my country.
On June 17, the National Development and Reform Commission, the Ministry of Ecology and Environment, and the Ministry of Industry and Information Technology issued a notice confirming that June 29th to July 5th of this year will be the National Energy Conservation Promotion Week, with the theme of "Green Water and Green Mountains, Energy Conservation and Efficiency".
“十三五”以来，中国钢铁行业节能成效显著
"China Metallurgical News" reporter: Would you please talk about what achievements and experiences have been achieved in the promotion of structural energy saving, technological energy saving and management energy saving in China’s steel industry since the "13th Five-Year Plan"?
Head of Energy Conservation of the Steel Association: Since the "Thirteenth Five-Year Plan", the steel industry has accelerated transformation and upgrading, implemented various energy conservation and environmental protection measures, and actively promoted green and sustainable development of the industry. Energy conservation and consumption reduction have achieved remarkable results.
As the forerunner of supply-side structural reforms, the iron and steel industry has completed the 5-year upper limit target task of eliminating excess capacity of 100 million tons to 150 million tons. The supply-side structural reform of the steel industry has achieved good results in removing capacity, which has cleared the obstacles for the long-term healthy development of the steel industry, eliminated the "stubborn diseases", boosted confidence, and laid the foundation for the steel industry to develop further green and high quality . The strict implementation of the Energy Conservation Law has promoted steel capacity reduction, which in turn has promoted steel energy conservation and consumption reduction. With the continuous improvement of the utilization rate of steel production capacity, in 2019, the comprehensive energy consumption per ton of steel of steel association members has been reduced to 552.96 kg of standard coal, a decrease of 3.3% compared with 2015.
Since the "Eleventh Five-Year Plan", the steel industry has entered an important period of vigorously promoting advanced technical measures for energy conservation and emission reduction. Iron and steel energy saving has also undergone significant adjustments in the process structure such as continuous casting and rolling, which has achieved significant results, and has shifted to system energy conservation led by advanced energy-saving technologies represented by "three uses and three uses" and the construction of energy management and control centers. Over the past ten years, through the efforts of enterprises in the whole industry and the effective organization and promotion of the Environmental Protection and Energy Conservation Working Committee of the China Iron and Steel Industry Association, the energy conservation concept of steel companies has become more and more in-depth, and the integration of energy conservation and environmental protection has become closer and closer. More and more significant. In the long run, with the continuous accumulation and supply of scrap steel resources, the innovation of short-process technology, the further expansion of low-carbon metallurgy and clean energy will inject new impetus into energy-saving and low-carbon steel.
"China Metallurgical News" reporter: In recent years, my country's iron and steel enterprises have actively participated in the "Energy Efficiency Leader" selection activity carried out by the Ministry of Industry and Information Technology and the energy efficiency benchmarking competition organized by the Steel Association. Please tell us about this situation.
Head of Energy Conservation of the Steel Association: The selection of "Energy Efficiency Leader" carried out by the Ministry of Industry and Information Technology lasted for 3 years. The steel industry chose a separate process for evaluation because of its particularity. Because this activity is voluntary registration, due to the influence of the scope of the participating companies, fewer companies have been selected (the “energy efficiency leader” of the steel industry in recent years includes: the sintering process of Baosteel Xinjiang Bayi Steel Co., Ltd. in 2017; In 2019, the sintering process of Baosteel Zhanjiang Iron and Steel Co., Ltd. and the converter process of Jiangsu Shagang Group Co., Ltd.). For iron and steel enterprises, this activity may be more indicative of a call to lead, encouraging enterprises to dig deep from all aspects of potential and improve energy efficiency. Although there are not many enterprises selected, they have made highlights and characteristics, thus becoming a leader in industrial energy conservation.
Since 2007, the Steel Association and the China Metallurgical and Building Materials Trade Union jointly organized the “National Energy Conservation and Energy Consumption Reduction Competition for Key Large-Scale Energy-Consumption Iron and Steel Production Equipment”. The competition has been held for 12 sessions, with a total of 2000 cubic meters and above Among the large blast furnaces, large converters of 120 tons and above and large sintering machines of 300 square meters and above, 45 champion furnaces and 172 winning furnaces were selected.
