On December 23, China's first near-zero carbon steel production line with a capacity of million tons was fully operational in Zhanjiang, marking a major breakthrough for China's steel industry in the field of green and low-carbon development.
This production line adopts an advanced hydrogen metallurgical electrosmelting process, using hydrogen as the "protagonist" to replace traditional coke, which greatly reduces carbon emissions and provides a brand-new path for China's steel industry to get rid of its deep dependence on traditional fossil energy. The direct reduced iron produced by the core hydrogen-based vertical shaft furnace has achieved the expected metallization rate; the efficient and green electric furnace and other facilities have further improved energy utilization efficiency. Compared with traditional processes, this production line can reduce carbon emissions by 50% to 80%. This hydrogen-based steelmaking technology has revolutionized the traditional high-energy-consuming and high-polluting steelmaking process, making steel increasingly green and low-carbon.
Wang Hongliang, head of the Zhanjiang steelmaking project team of China Baowu Steel Group, introduced that the million-ton-level near-zero carbon steel production line can reduce carbon emissions by more than 3.14 million tons per year, which is equivalent to creating 2,000 square kilometers of forest. It provides a model for the low-carbon transformation of steel enterprises and contributes to the high-quality development of the steel industry.
