Baogang Steel Union leads breakthroughs in low-carbon metallurgy technology. Its diverse product matrix empowers green infrastructure.
As an industry pioneer, the first phase of the world's first 1.20 million-ton hydrogen metallurgy demonstration project was officially put into operation, and the carbon footprint was reduced to 1.8tCO ²/t. The supporting production of Q355D seamless steel pipes, I-beams and other products has been used in batches in Bohai Oilfield and Central Asia Natural Gas Pipeline Projects. The proportion of green steel exports exceeded 40% 47% throughout the year. During the same period, Ningbo Iron and Steel's "Double Carbon Best Practice Energy Efficiency Benchmarking Demonstration Enterprise" passed the acceptance, marking the industry's energy conservation and carbon reduction technology entering the stage of large-scale application.
Hydrogen metallurgy technology breakthrough: from laboratory to industrial demonstration
The world's first coke oven gas zero reforming hydrogen metallurgy project of HBISCO Group achieved a 70% reduction in carbon emissions per ton of steel. Its weathering channel steel (09CuPCrNi) has a salt spray resistance life of more than 15 years, and has been successfully applied to the photovoltaic support system in Xiongan New Area 47. Baotou Steel Steel Co., Ltd. has simultaneously promoted hydrogen-based direct reduced iron technology. The supporting Z35 tear-resistant I-beams and angle steel have broken through the 2 million times in the Sichuan-Tibet railway tunnel project, helping to reduce the weight of the project by 25% . In addition, Nippon Steel Blast Furnace Hydrogen Reduction technology implementation reduced carbon dioxide emissions by 43%, providing technical benchmarking for export products under the pressure of international carbon tariffs (CBAM)
Zero-carbon electric arc furnace technology: Short process reshapes industrial ecology.
Zero-carbon electric arc furnace production line, using green electricity and hydrogen-based reduction technology, reduces the energy consumption of seamless steel pipe and round steel smelting by 40%, and the grain size reaches ASTM 8. Its precision cold-drawn seamless steel pipe (tolerance ± 0.05mm) is exported to the South East Asia automotive gear market, and the profit margin is increased by 20% compared with traditional products . Ningbo Steel has undergone extreme energy efficiency transformation, and the comprehensive energy consumption per ton of steel has decreased by 5.87%. Q690D high-strength steel plate is used in LNG storage tank manufacturing, and the impact power of -196 ° C meets the standard
Scrap circular economy: short processes account for more than 20%
The oxygen content of the high-purity round steel (20CrMnTi) produced is less than or equal to 15ppm, which is used in the manufacture of new energy vehicle drive shafts, with a premium rate of 8% . Leading enterprises such as HBIS and Angang have accelerated the layout of scrap steel pretreatment centers, and their recycled steel I-beams and channel steel products have reduced carbon footprint by 65% compared with traditional processes, and have been certified by the European Union EPD
Transforming finance empowers: capital and technology
The special project supports the upgrading of zero-carbon electric arc furnaces and precision profile production lines. Its corrosion-resistant seamless steel pipes (316L) account for 25% of Saudi seawater desalination projects . Hebei has launched the country's first steel transformation financial catalog, covering 176 technologies, to promote the transformation of "blast furnace-converter" to "hydrogen-based shaft furnace + electric furnace"
Global Collaboration and Future Layout: Green Hydrogen Transmission to the West and Intelligent Traceability
Build a "hydrogen energy corridor", with the goal of green hydrogen metallurgy capacity accounting for more than 30% in 2030 . Simultaneously promote the blockchain traceability system to realize the whole life cycle carbon footprint tracking of seamless steel pipes and I-beams, and link with the Zhejiang virtual power plant platform to optimize green power dispatching58. In the next five years, China's steel industry may implement carbon neutrality closed-loop through CCI technology. Baotou Steel Union will use the strategy of "rare earth steel + high-end profiles", with the goal of reducing carbon emission intensity by 95% in 2060 compared with 2020
