The steel industry is steadily moving towards the medium-high end

-- Complete industrial system, strong domestic market support, so that the steel industry chassis more stable.

Last year, the Luoyang Science and Technology Museum under construction was the first to "eat crabs" in the national construction field: the first application of domestic heavy H-shaped steel.

"In the past, when constructing large steel structure buildings in China, either imported H-shaped steel products were used, or plate welding was used, which was difficult and costly." Zhang Jian, director of Masteel Technology Center, said that in the past, architectural designers are not familiar with what domestic steel enterprises can provide products, these two years, Masteel in order to expand the market, take the initiative to strengthen communication and close cooperation with nearly 100 architectural design institutes in China, "' hand 'Tsinghua University architectural design Institute, let Luoyang Science and Technology Museum use the high-quality steel we provide, but also let Masteel harvest a new growth point."

Construction, machinery, home appliances, automobiles, ships, high-speed rail, bicycles, motorcycles, containers, hardware products... Rich application scenarios, complete industrial system for China's iron and steel enterprises have brought the unique advantage of "near the water tower first".

On the one hand, "refueling" for production. After years of development, China's iron and steel equipment level ranks among the world's first-class, coking, sintering, iron making, steel making, continuous casting, steel rolling and other main processes of the main technical equipment can basically be independently developed, large-scale metallurgical equipment localization rate reached more than 95%.

On the other hand, "upping the ante" for demand. "In recent years, the rapid development of China's new energy automobile industry has made the market demand for high-grade non-oriented silicon steel explosive growth. In 2017, the domestic market demand was only 60,000 tons, and this year it is expected to exceed 380,000 tons." In the view of the South China Sea, the transformation and upgrading of the manufacturing industry will bring broad space for high-end steel products.

Development has ushered in a new phase

In the future, efforts should be made to overcome resource and environmental constraints and achieve high-quality development

More than 130 advanced environmental protection technologies such as desulfurization and denitrification are used to achieve full purification of flue gas and efficient treatment of pollutants in production units. Using a new generation of treatment technology, the steel slag "eat dry squeeze"; Create fully closed corridors and media pipelines to minimize the environmental impact of coke, iron ore powder... In September 2020, Hebei Iron and Steel Tanggang New Area was put into operation, and all emission indicators were designed to be 10% lower than the most stringent standards in the industry.

Since the 18th National Congress of the Communist Party of China, under the joint promotion of relevant regulatory requirements and enterprise development needs, iron and steel enterprises have generally increased investment in environmental protection, the application of advanced energy saving and emission reduction technologies, and a number of green garden-style factories and environmentally friendly factories have been born. By the end of 2021, 34 enterprises in the steel industry with about 225 million tons of steel production capacity have completed ultra-low emission transformation publicity.

According to the statistics of the China Iron and Steel Association, compared with 2012, in 2021, the average comprehensive energy consumption per ton of steel in key iron and steel enterprises has been reduced from 602.71 kilograms of standard coal to 550.43 kilograms of standard coal, and the gap with the world's advanced level has been greatly reduced; The emissions of sulfur dioxide and smoke dust per ton of steel also decreased by 81.41% and 63.44% respectively.

It is worth noting that the ultra-low emission transformation is mainly aimed at PM2.5, sulfur dioxide, nitrogen oxides and other pollutants, and to achieve the goal of carbon peak carbon neutrality, the steel industry still needs to implement a new task - carbon reduction.

"Among all industrial sectors in China, the steel industry is second only to the thermal power industry in terms of carbon emissions." Chen Derong, secretary of the Party Committee and chairman of China Baowu Iron and Steel Group Co., LTD., believes that the "double carbon" goal will promote fundamental changes in the development model of the steel industry, which requires the steel industry to develop and promote new energy metallurgical technology as soon as possible.

Many enterprises have taken action: Baowu, Hesteel, Jianlong, Jiusteel and other enterprises have carried out research and development on cutting-edge low-carbon technologies such as hydrogen-rich carbon cycle blast furnaces and hydrogen-based shaft furnaces and made significant progress. It is reported that the National Development and Reform Commission is working with relevant departments to develop a carbon peak implementation plan for the steel industry to further refine the relevant requirements.
