Hydrogen metallurgy process under the background of carbon neutrality may be popular

China's iron and steel industry has never stopped the exploration and practice of hydrogen metallurgy process. As early as the 1970s, China began to design and build a gas-based shaft furnace for the treatment of vanadium titanium magnetite pellets. In the 1980s, Baosteel carried out the semi-industrial test research on the production of direct reduced iron by BL coal-to-gas process and shaft furnace. Entering the new century, Taihang built a coke oven gas-shaft furnace direct reduction project with an annual output of 300,000 tons DRI; More recently, Hesteel Group and Italy's tenova Group officially signed an agreement to build a demonstration hydrogen energy development and utilization project, including an annual output of 600,000 tons of ENERGIRON direct reduction plant, which is scheduled to be put into production by the end of 2021. It is believed that in the near future, China's hydrogen metallurgy process will continue to mature, and gradually become the main force of ore smelting, leading the updated trend of industrial cleaner production.
