In order to promote the green transformation of China's iron and steel industry and the standardization of hydrogen metallurgy technology, in early September, many domestic experts and enterprise representatives in the field of hydrogen metallurgy gathered in Chongli, Hebei Province, to hold the first world hydrogen metallurgy technology exchange conference. At the meeting, the relevant technologies, standardization construction and demonstration application of hydrogen metallurgy were discussed in depth, and the development direction of hydrogen metallurgy technology was clarified. At the meeting, the newly established "Joint Working Group on Hydrogen Metallurgy Standards" will coordinate the development of national standards related to hydrogen energy smelting in the iron and steel industry, and lead the iron and steel industry in the application of new low-carbon technologies and processes. "Hydrogen metallurgy is an important technical direction to promote the green and low-carbon development of iron and steel industry, and will promote the development of hydrogen metallurgy technology in China with a perfect hydrogen metallurgy standard system." Zhang Longqiang, Secretary of the Party Committee and President of the Institute of Information Standards for Metallurgical Industry, said. It is understood that many iron and steel enterprises in China are deploying hydrogen metallurgy. For example, Zhang Xuan Technology of Hegang Group has increased the development and utilization of hydrogen energy, and for the first time in the world, coke oven gas is used for "self weight" hydrogen production to produce high-quality direct reduced iron; The third stage of industrial test of hydrogen rich carbon circulation blast furnace of China Baowu No.8 Iron and Steel Co., Ltd. was opened, entering a new stage of full oxygen and gas self circulation; Shanxi Jinnan Iron and Steel Co., Ltd. has carried out industrial tests of coke oven gas injection and pure hydrogen injection respectively on 1860m3 blast furnaces... Compared with the deep layout of hydrogen metallurgy technology by foreign steel enterprises, "the low-carbon transformation of China's steel industry needs more comprehensive technology, and the low-carbon development needs more standard leading and standard first." Jiang Wei, Deputy Secretary of the Party Committee of China Iron and Steel Industry Association, said. Standards are the catalyst to accelerate the diffusion of innovation achievements. "As a breakthrough production process in the iron and steel industry, hydrogen metallurgy should make standards take the lead in technological innovation and promotion, and promote the interactive development of standardization and scientific and technological innovation." Cui Shuang, the chief staff member of the Standards Division of the Science and Technology Department of the Ministry of Industry and Information Technology, stressed. In terms of industrial utilization of hydrogen energy, China's iron and steel enterprises have tackled a number of key technologies in hydrogen metallurgy. "We have broken through the technological bottlenecks of hydrogen metallurgy in the whole process, such as hydrogen metallurgy shaft furnace pellet preparation and its metallurgical performance, hydrogen gas based shaft furnace reduction technology and equipment, and achieved the capture, separation and efficient recycling of carbon dioxide in the hydrogen metallurgy gas based shaft furnace process." Lu Peng, manager of Hebei Zhangxuan High tech Hydrogen Metallurgy Co., Ltd. Today, hydrogen metallurgy has become the key technology for the transformation of China's steel industry to green and low-carbon development, and will lead the steel industry to enter the era of smelting "green steel" by "replacing coal with hydrogen". "In the future, we will rely on science and technology to increase innovation and breakthroughs in key and core technologies of hydrogen metallurgy, strive to be the leader and practitioner of hydrogen metallurgy and carbon reduction actions, and provide a 'China plan' for low-carbon and green development of the world steel industry." Yu Yong, Secretary of the Party Committee and Chairman of Hegang Group, said. (Liu Xinshe)
