钢铁业主攻极致能效

Core Viewpoint - The steel industry is undergoing a significant transformation towards energy efficiency and carbon reduction, with the implementation of the "Extreme Energy Efficiency Project" aimed at achieving substantial energy savings and CO2 emissions reductions by 2025 [2][3][4]. Group 1: Energy Efficiency and Carbon Reduction Achievements - The steel industry has achieved energy savings exceeding 24 million tons of standard coal and reduced CO2 emissions by 60 million tons, surpassing the targets set in the energy-saving and carbon reduction action plan [2]. - As of now, 143 selected enterprises have a crude steel capacity of over 750 million tons, with energy consumption in blast furnaces and converters decreasing by 2.45% and 12.22% respectively compared to 2023, resulting in cumulative energy savings of 13.2 million tons of standard coal and a reduction of 34 million tons of CO2 [3]. Group 2: Cost Reduction and Efficiency Improvement - The steel industry is facing multiple pressures, leading companies to focus on extreme energy efficiency, resulting in significant cost reductions. For instance, Jiangyin Xingcheng Special Steel achieved annual cost savings of 136 million yuan by reducing energy consumption [4]. - Over 50 demonstration enterprises have invested a total of 40.9 billion yuan over three years, with an average investment of 700 million yuan per enterprise, leading to a reduction in energy costs of 29 yuan per ton of steel and an average payback period of 3.27 years [4]. Group 3: Technological Innovation and Application - Technological innovation is crucial for addressing the high carbon emissions in the steel industry, with the "Extreme Energy Efficiency Project" providing a technology list that includes 134 advanced technologies across various processes [6]. - The implementation of intelligent management systems has led to a reduction in temperature drop at the iron-steel interface, resulting in significant energy savings. For example, Baowu Steel's system reduced temperature drop by 30 degrees Celsius, saving 9,580 tons of standard coal annually [7]. Group 4: Future Directions and Collaborative Efforts - The steel industry will be included in the national carbon emissions trading market by 2025, indicating a shift towards dual control of carbon emissions in terms of total volume and intensity [8]. - The focus will shift from single-process energy efficiency to a comprehensive evaluation system integrating carbon control, emphasizing system integration and digital twin technologies [8][9]. - The China Iron and Steel Association (CISA) plans to promote collaborative innovation among enterprises, universities, and research institutions to address technological challenges and enhance the industry's carbon neutrality efforts [9][10].
