Recently, the Loudi Municipal Bureau of Industry and Information Technology released the "Implementation Plan for Carbon Peak in Loudi City's Industrial Sector", which mentioned that relevant regulations on capacity replacement and project filing, environmental impact assessment, energy conservation assessment and review, etc. should be strictly implemented to strictly prevent "land regulations" "Steel" has revived and the excess capacity that has been resolved has resumed production. Optimize the structure of raw materials, encourage enterprises to make full use of scrap steel resources, increase the ratio of scrap steel in steelmaking, support the establishment of regional large-scale scrap steel recycling, processing and distribution centers, and improve the ability to guarantee the supply of scrap steel resources. Optimize the process structure, develop short-process electric arc furnace steelmaking in an orderly manner, increase green and low-carbon technological transformation, implement coking, sintering, ironmaking, and steelmaking process equipment transformation and upgrading, and strengthen the cascade comprehensive utilization of waste heat and energy. Optimize the energy structure, increase the proportion of green power usage, and steadily reduce the proportion of coal consumption. Optimize the product structure, focusing on the development of high-performance (ultra) high-strength steel mainly for construction machinery steel, automotive steel, wear-resistant steel, tool and die steel, and riveting screw steel, as well as automotive sheet, silicon steel, home appliance sheet, enameled steel, etc. Focus on high-quality cold-rolled sheets and coated sheets, accelerate the development of high-performance silicon steel and its deep processing industry, cultivate and strengthen special series of products such as military steel, medium and high-end stainless steel, and composite materials, and promote the transformation of the steel industry to "high-end, precision, and cutting-edge". Strengthen non-blast furnace ironmaking, hydrogen metallurgy and other advanced technology research, and carry out pilot demonstrations of advanced low-carbon technology industrialization. Promote the application of a new generation of information technology in the steel industry, strengthen the construction of intelligent energy management and control centers, and improve the level of digitalization and intelligence. By 2025, the proportion of production capacity above the energy efficiency benchmark level in ironmaking and steelmaking processes will reach 30%, and the proportion of high-efficiency steel varieties will reach 65%.
