How to realize the low-carbon route in the steel industry

(I) Pattern process reengineering
We will promote mergers and reorganizations, optimize industrial layout, reengineer technological processes, improve energy efficiency, and reduce carbon emissions. Promote the limiting energy efficiency of the whole process, adopt energy-saving technology, and realize the efficient use of energy within the production process of rectangular hollow section; The whole process of ore iron steel rolling is optimized and connected to improve the process energy efficiency; Efficient recovery of waste heat and energy resources to achieve limiting energy saving and carbon reduction.

(2) Reduction of resource consumption
We will promote the whole-life cycle management of products, promote green production, manufacture low-carbon materials, and reduce social resource consumption. Implement the recycling of resources, lay out the recycling and processing industry of recycled steel raw materials, and improve the utilization of solid waste resources containing iron and carbon; Deepen the integration of industry and city, mutual supply of energy and resources, and coordinated carbon reduction of China hollow section tube by saving and replacing primary resources; Enhance employees’ low carbon awareness and advocate simple, moderate, green and low carbon lifestyle.

3. Improving the energy structure
We will develop new energy industries, adjust the energy mix, and develop energy storage technologies and a system of multi-energy complementary energy. The layout of vanadium battery energy storage has made a major breakthrough in the energy density of electrolyte, a key material of Angang all-vanadium flow battery. On this basis, the industrialization of all-vanadium flow energy storage technology is accelerated to provide solutions for large-capacity energy storage.

(4) Demonstration of green mines
Give full play to the advantages of advanced mining and beneficiation technology to improve the utilization efficiency of mineral resources; Make full use of mine land resources and develop green energy; Step up reclamation efforts and increase ecological carbon sinks of structural steel pipe. To build green, intelligent and intelligent demonstration mines, improve the comprehensive utilization efficiency of resources, implement efficient and intelligent mining and selection, and reduce process consumption; Give full play to technological advantages, improve iron concentrate grade, improve the comprehensive utilization rate of vanadium titanium ore.

5. Frontier technology innovation
We will continue to take the lead in scientific and technological innovation, accelerate the research and development and application of low-carbon metallurgical technologies of black iron steel pipe and carbon capture, utilization and storage technologies, and open and share the results. Using green electricity such as wind power and photoelectric power, efficient electrolytic water to produce green hydrogen and direct reduced iron, the first set of pilot production line in China was built.
