2025-07-26
From coal-fired heating to photovoltaic power, from manual forging to digital factories, a green revolution is quietly unfolding in China's industrial heartland.
In Dingxiang County, Shanxi Province—where flange production accounts for 44% of the nation’s total, wind turbine tower flanges hold a 60% domestic market share, and exports make up over 30% of China’s total flange exports—this small northern Shanxi county, hailed as the "Forging Capital of China," hosts 319 forging enterprises with an annual output of 1.7 million tons and a total production value of ¥17.05 billion.
Yet, stepping into Dingxiang’s factories today reveals a stark contrast to the past: scenes of veteran craftsmen judging furnace temperatures by experience have been replaced by real-time monitoring of over 2,000 datasets; once "dust-covered" workshops have transformed into bright, clean "green factories."
01. Industrial Transformation: A Green Leap from Experience-Driven to Data-Driven
As a foundational segment of equipment manufacturing, the Forged Flange industry is undergoing a radical transformation. At the 2025 Shanxi (Dingxiang) Flange Forging Industry Expo, 300 supply chain enterprises showcased their shift from traditional manufacturing to green, intelligent production.

Hengyue Group’s digital workshop has become an industry benchmark, with 5G coverage across the entire facility and 70% of equipment collecting real-time production data. Intelligent upgrades have boosted its production efficiency by 20% and reduced defect rates by 35%.
Guanjialing Flange Forging Co. has built an integrated digital management platform covering "production, supply, sales, finance, and inventory," enabling product traceability and automated financial reporting. Its products comply with 268 national and industry standards, span over 460 materials, and export to more than 30 countries.
"Traditional industry ≠ low-end industry," declared Yan Yonghong, Secretary-General of the Dingxiang Flange Forging Association, encapsulating the industry’s transformation: "When flange precision reaches micrometer levels and carbon emissions are measured in grams, Dingxiang will become China’s ‘hardcore calling card’ in forging on the global stage."
02. Low-Carbon Practices: A Green Forging Revolution Under Environmental Pressure
Amid China’s "dual carbon" goals, the flange forging industry has spearheaded an environmental revolution. As Shanxi’s only pilot for carbon footprint certification in flange products, Dingxiang is accelerating the development of a global carbon labeling system to dominate green trade.

Currently, all forging enterprises in Dingxiang have replaced coal heating with natural gas, and installed renewable energy capacity has reached 207.45 MW. At Tianbao Group’s factory rooftops, a 4,454 kW distributed photovoltaic project reduces CO₂ emissions by 425 tons annually.
Dingxiang has also established a low-carbon cloud platform for industrial parks, providing data-driven governance tools to optimize energy use and carbon management.
In Jiangsu, policymakers are actively driving transformation. Under the Implementation Opinions on Promoting High-Quality Development of the Casting and Forging Industry*, the province aims to reduce particulate emissions by over 30% and energy consumption per ton of forgings by 5% by 2025.
03. Technological Breakthroughs: Green Manufacturing Innovations by Industry Leaders
Leading enterprises are pushing the limits of green forging. In July 2025, ELITE Energy Equipment delivered a milestone project: a 12-meter-diameter, 219-ton tower flange for CSSC Haizhuang’s 25 MW offshore wind turbine—China’s largest domestically produced model.

With a rotor diameter of 305 meters, this turbine represents the pinnacle of China’s offshore wind technology. ELITE operates over 10 offshore wind forging lines worldwide and has mastered rapid mass production of large-diameter flanges.
Notably, ELITE’s in-house short-process steel mill employs carbon-reducing techniques like scrap recycling, hot material transfer, and oxygen-enriched combustion to support low-carbon turbine production.
The company also collaborates with academicians Li Yiyi and Li Dianzhong of the Chinese Academy of Sciences on rare-earth steel R&D, enhancing the performance of offshore wind components.
04. Policy Support: A National Blueprint for Green Forging
This transformation is backed by national strategy. In 2023, China’s MIIT, NDRC, and MEE jointly issued the Guidelines for High-Quality Development of the Casting and Forging Industry, targeting 100+ green factories by 2025 and a 30% reduction in particulate emissions from 2020 levels.

The guidelines mandate short-process casting, energy-efficient melting equipment, waste heat recovery, and foundry sand recycling, promoting the production of key components like the Stainless Steel Flange with greater efficiency and lower environmental impact. Jiangsu Province has gone further, planning 100 intelligent and green demonstration factories by 2025, with annual recycled foundry sand exceeding 3 million tons.
These policies chart a clear path toward low-carbon, smart forging, ensuring the manufacturing of essential products such as the Stainless Steel Flange aligns with the nation's sustainability goals.
05. Global Trends: International Explorations in Green Forging
China isn’t alone in this shift. In July 2025, Tata Steel UK launched an electric arc furnace R&D project with Cambridge and Imperial College London to develop AI-driven steel optimization for sustainable production.

Meanwhile, HBIS Group’s Zhangxuan Technology pioneered China’s first near-zero-carbon "hydrogen-based shaft furnace + EAF" line. In 2024, it achieved the world’s first industrial-scale "green hydrogen" steelmaking, proving the viability of "green power → green hydrogen → green steel."
06. The Road Ahead: Challenges and Opportunities
With tightening "dual carbon" policies, the forging industry faces stricter environmental demands. In 2024, metallurgical firms invested ¥42 billion in emissions reduction, earning ¥3.5 billion from carbon trading.

Experts predict hydrogen-based direct iron reduction will commercialize by 2030, cutting steel’s carbon footprint below 0.5 tons per ton, with carbon asset management becoming a profit driver.
In Dingxiang, the government-industry Xinhua-Dingxiang Flange Price Index leverages big data to guide green transitions. As of June 2025, wind flange prices rose 0.44% monthly, while petrochemical flanges surged 6.76%.
Conclusion
In ELITE’s workshops, 12-meter flanges embark on their journey to ports—each a testament to China’s forging revolution. From Dingxiang’s green factories to HBIS’ hydrogen metallurgy, the industry redefines itself with micrometer precision and gram-scale carbon accountability.
