On July 2, 2024, at the main forum of the 26th Annual Conference of the Chinese Association for Science and Technology, the Chinese Association for Science and Technology released the 2024 major scientific issues, engineering and technological challenges, and industrial and technological issues. Among them, the "Using Clean Energy to Achieve Low Cost and Low Carbon Ironmaking" recommended by the Chinese Society of Metals was selected as one of the top ten industrial technical issues.
Since 2018, the China Association for Science and Technology has organized a collection and release activity for major scientific and technological problems, guiding scientific and technological workers to keep up with the global trend of scientific and technological development, focusing on national major needs, conducting original and leading research, and continuously consolidating the technological support for high-quality development. In 2024, the China Society of Metals not only organized member organizations, professional branches, and local societies to collect and select difficult problems, but also recommended three scientific questions, five engineering and technical problems, and five industrial and technical problems to the China Association for Science and Technology. The Chinese Society of Metals also took the lead in organizing the selection of problems and difficulties in the field of advanced materials. On April 8, 2024, a preliminary selection meeting in the field of advanced materials was held in a combination of online and offline forms. A preliminary selection academic expert group composed of 13 top experts in the industry selected 4 problems and difficulties through voting. On June 14th, three difficult issues passed the evaluation of the academician expert group, namely "the emergence of flexible materials through coupling and hybridization", "the theory and technology of quality control for large-sized semiconductor silicon single crystals", and "the use of clean energy to achieve low-cost and low-carbon ironmaking".
The use of clean energy to achieve low-cost and low-carbon ironmaking is recommended by the Chinese Society of Metals. Traditional ironmaking processes heavily use carbon as a heat source and reducing agent, making it one of the key processes for emitting greenhouse gases (CO2). In addition to carbon emissions, the series of pollution problems caused by carbon in the pre processes (sintering, pelletizing, coking, etc.) also have a serious impact on the survival and sustainable development of traditional ironmaking processes. Applying clean energy such as hydrogen to steel and metallurgical production is an important way for the low-carbon and green transformation and upgrading of the steel industry. The key is to achieve the maturity and industrial application of low-cost hydrogen preparation, storage and transportation technology, and core key technologies of hydrogen metallurgy, exploring new processes, technologies, and paths for low-carbon development of China and the world's steel industry.
In the major scientific and technological problem collection and release activities carried out by the China Association for Science and Technology over the years, the Chinese Society of Metals, relying on the consortium of the Advanced Materials Society of the China Association for Science and Technology, has successfully recommended two selected problem problems, namely "How to break through the preparation theory and technology of large-sized crystal materials?" and "How to prepare high-end bearing steel materials with high cleanliness, high homogeneity, and ultrafine grain." These have received encouragement and recognition from the China Association for Science and Technology, and also strive to promote the scientific research and industrial development of advanced materials in China through this.
