——hebei iron and steel industry achieves new breakthroughs in green transformation (subtitle)
xinhua news agency, shijiazhuang, october 5th. xinhua news agency reporters yue wenting and liu taoxiong
hebei is a major steel province, and the steel industry is the main frontier for environmental protection management in hebei province. in 2022, hebei launched an action to comprehensively achieve a in environmental protection performance of steel companies, which forced the steel industry to transform and upgrade. currently, 39 steel companies have completed a in environmental protection, ranking first in the country in number. under the guidance of the green development concept, the "gold content" of hebei province's steel enterprises has also continued to increase.
reduce emissions and create a new green look
when you walk into delong steel co., ltd. located in xindu district, xingtai city, you can see green plants, flowers, and creative sculptures everywhere. the abandoned factories and vacant land vacated by the company's transformation and upgrading have become landscapes, and many tourists come to visit.
walking in the "garden-style" factory, huo zenghe, the company's environmental protection minister, was full of emotions: "in the past, the workshop was full of fire, hot and smokey, and workers in the workshop had to wear high-temperature-resistant work clothes to operate. it took less than 2 hours to shift changes and visits are even more impossible.”

since 2014, delong steel has invested a total of more than 4 billion yuan in in-depth environmental protection management. in 2020, delong steel company became hebei's first long-process steel company with grade a environmental performance, reducing nitrogen oxide emissions by more than 100 tons per year. in the same year, delong iron and steel cultural park became an aaaa-level tourist attraction.
"the brand 'environmental performance a-level enterprise' is our intangible asset. in special periods such as heavily polluted weather and off-peak production, we can independently take emission reduction measures. production is relatively stable, which further increases the competitiveness and comprehensiveness of the company. strength." said yang shengmin, director of the company's party and mass comprehensive department.
the effectiveness of environmental governance work has also enhanced the reputation of delong steel company and brought more development opportunities to the company. yang shengmin said that every year, steel companies and environmental protection companies come specifically to benchmark and learn one after another, and in the first half of 2024, a total of nearly 10,000 people were received. at the same time, the company's technical team is often invited to provide consulting and guidance services to other companies. normalized and multi-level communication provides a platform for enterprises to grasp industry development trends and market trends, and promotes sustainable development of enterprises.
seeking upgrades to open up new space for development
in the extra-thick and high-strength steel plate production workshop of hebei puyang iron and steel co., ltd. in wu'an city, pieces of red steel billet move back and forth on the roller table. after processing, they will be used to manufacture key components of high-end coal mining machinery. at the same time, the company's ultra-low emission management and control integrated platform monitors the emission data of air pollutants in production in real time.
"compared with traditional production lines, the upgraded automated production system has wider application scenarios, faster parameter feedback, lower-carbon product production, can clearly indicate comprehensive information on the environmental impact of the product's entire life cycle, and promotes green throughout the entire process and process. low-carbon transformation and development," said li jianchun, director of the company's environmental protection department.

in recent years, puyang iron and steel has taken emission reduction and efficiency creation as its fundamental starting point, and has continued to consolidate the effects of ultra-low emission transformation. it has invested more than 8 billion yuan in total and has steadily explored and solidified its efforts in clean transportation, monitoring and control, intelligent manufacturing, low-carbon development and other aspects. advance, and achieve a in environmental performance in 2023. in the process of improving equipment and environmental protection levels, enterprises have achieved management innovation, process innovation, and product innovation.
li jianchun said: “the company has successively upgraded a large number of high-end steel production equipment, and the operational stability of production and environmental protection equipment has been significantly improved, providing a strong basis for the development of new energy steel, electrical steel, high-end customized modulated steel and other products. support."
brave innovation leads the industry in new directions
when you are at the site of the hbis zhangxuan technology 1.2 million-ton hydrogen metallurgy demonstration project, you don’t feel like this is a steel factory, but like a chemical park. the traditional blast furnace was replaced by a silver-white hydrogen-based shaft furnace full of technology.
compared with the traditional long process model of "blast furnace + converter", this project adopts "hydrogen-based shaft furnace + high-efficiency electric furnace". the hydrogen in the coke oven gas acts as a reducing agent and process fuel to react with oxidized pellets to generate direct reduced iron. (dri), the dri products are then transferred to the electric furnace to smelt "green steel". compared with long-process processes of the same production scale, the first phase of the project can reduce carbon dioxide emissions by 800,000 tons per year, with an emission reduction rate of 70%.
the china iron and steel industry association believes that this project is an important milestone in the transformation from traditional "carbon metallurgy" to new "hydrogen metallurgy" in the history of china's steel and even the world's steel history. as a pioneer, there is no experience at home or abroad to learn from, and the project needs to find its own way from construction to operation.
li lijie, the operating manager of the hydrogen metallurgy operation area of zhangxuan technology, led his team to immerse themselves in the 100-meter shaft furnace production site day and night. after tens of thousands of tests, they finally broke through the bottleneck of the full-process hydrogen metallurgy technology. li lijie introduced that his team has applied for 59 patents related to hydrogen metallurgy and participated in the preparation of 7 national and industry standards. the metallization rate of dri products has stabilized at more than 94%.
"not long ago, we also successfully applied green hydrogen as reducing gas to achieve stable production, verifying the technical feasibility of 'green electricity-green hydrogen-green steel' production, enriching the source of raw gas for hydrogen metallurgy, and marking zhang xuan's scientific and technological exploration the all-green hydrogen and near-zero carbon hydrogen metallurgical technology has taken an important step forward," said li lijie.
