In order to promote the green transformation of China's steel industry and the standardization of hydrogen metallurgy technology, in early September, a number of domestic experts and enterprise representatives in the field of hydrogen metallurgy gathered in Chongli, Hebei Province, and held 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 defined.
At the meeting, the newly established "Joint Working Group on hydrogen metallurgy standards" will coordinate the development of national standards related to hydrogen metallurgy in the steel industry and lead the application of low-carbon new technologies and processes in the steel industry.
"Hydrogen metallurgy is an important technical direction to promote the green and low-carbon development of the iron and steel industry, and will promote the development of China's hydrogen metallurgy technology with a perfect hydrogen metallurgy standard system." Zhang Longqiang, Secretary of the Party committee and President of the Metallurgical Industry Information Standards Research Institute, said.
It is understood that many steel enterprises in China are laying out hydrogen metallurgy. For example, Zhangxuan technology of Hegang group has increased the development and utilization of hydrogen energy, and for the first time in the world, it has adopted coke oven gas "self weight rectification" to produce hydrogen and produce high-quality direct reduced iron; The third stage industrial test of hydrogen rich carbon circulation blast furnace of Baowu No; The 1860m3 blast furnace of Shanxi Jinnan iron and Steel Co., Ltd. has carried out industrial tests of injecting coke oven gas and pure hydrogen
Compared with the in-depth layout of hydrogen metallurgy technology by foreign iron and steel enterprises, "the low-carbon transformation of China's iron and steel industry needs more comprehensive technology, and the low-carbon development needs more standards leading and standards leading." Jiang Wei, deputy secretary of the Party committee of the China Iron and Steel Industry Association, said.
Standards are the catalyst for accelerating the diffusion of innovation achievements. "As a breakthrough production process in the iron and steel industry, hydrogen metallurgy should keep standards in the forefront of technological innovation and promotion, and promote the interactive development of standardization and scientific and technological innovation." Cui Shuang, director of the standards division of the science and Technology Department of the Ministry of industry and information technology, emphasized.
In terms of industrial utilization of hydrogen energy, China's iron and steel enterprises have tackled a number of key technologies of hydrogen metallurgy. "We have broken through the bottleneck of hydrogen metallurgy technology in the whole process, such as pellet preparation and metallurgical performance of hydrogen metallurgy shaft furnace, hydrogen gas-based shaft furnace reduction process technology and equipment, and realized the capture, separation and efficient recycling of carbon dioxide in hydrogen metallurgy gas-based shaft furnace process." Introduced by Lu Peng, manager of Hebei Zhangxuan high tech hydrogen metallurgy company.
Today, hydrogen metallurgy has become a key technology for the transformation of China's steel industry to green and low-carbon development, and will lead the steel industry into an era of "replacing coal with hydrogen" and smelting "green steel". "In the future, we will rely on science and technology, increase innovation and breakthrough in key and core technologies of hydrogen metallurgy, strive to be the leader and practitioner of hydrogen metallurgy and carbon reduction, and provide a 'Chinese plan' for the low-carbon and green development of the world steel industry." Yu Yong, Secretary of the Party committee and chairman of Hegang group, said.
