Promoting clean production in the steel industry

Accelerate the optimization of industrial energy structure and process flow
In the continuous research and development of hydrogen and non-fossil fuel and other clean energy smelting, at the same time, synchronous promotion of non-blast furnace ironmaking technology demonstration and total scrap electric furnace smelting process ratio, comprehensively reduce the current long process of iron smelting system of high pollutant emission and high energy consumption of carbon emissions of the current problem. We will promote the optimization and upgrading of the entire process of the square steel pipe, intensify efforts to support the steel industry in making use of 5G, industrial Internet and other new infrastructure for intelligent and green transformation and upgrading, and improve the level of cleaner production of enterprises through intelligent and green technologies. Steel production should be controlled in a differentiated manner, enterprises should be vigorously promoted to merge and reorganize, industrial concentration should be increased, layout optimization should be further promoted, and green development should be comprehensively implemented.

We will strengthen the spread and application of innovative and synergistic technologies for reducing pollution and carbon
During the 14th Five-Year Plan period, 80 percent of China’s steel production capacity was upgraded to ultra-low emissions, and the country’s coking capacity of 460 million tons was upgraded to cleaner production. Under the historical requirements of the comprehensive implementation of cleaner production in the rectangular steel tube, we will strengthen the demonstration and application of collaborative efficiency innovation technologies for pollution reduction and carbon reduction and green and low-carbon process technologies, and comprehensively enhance the green development and high-quality transformation capability of the industry through technological innovation.

First, we will further tap the potential of coordinating ultra-low emission pollution reduction with energy conservation and carbon reduction. Strengthen the optimization of the structure of the furnace charge, the use of waste heat to reduce the carbon source reduction technology application, and research and development of blast furnace gas faster, efficient and stable into the industrial application of structural steel pipe; Strict application of process control technologies such as reversing gas recovery in heating furnace to achieve pollutant emission reduction; At the end of the treatment process, more attention is paid to the potential mining of energy saving and low carbonization, and the research and development and operation of treatment technologies such as low-temperature SCR denitrification technology, SCR efficient and precise ammonia injection technology, and energy-saving and efficient dust removal facilities are carried out. Promote the joint recycling of wastewater from the black iron steel pipe and promote the industry-wide application of the process of reducing the amount of water-contaminated pollutants and reducing carbon.
