Abstract：The man-made agglomerate iorn ore and coke are the modern blast furnace ironmaking material basis. Modern blast furnace realizing green and low-carbon ironmaking needs to optimize the technical process and key technologies from the level of ironmaking procedure, and realize the collaborative optimization of multiple processes such as sintering, pelletizing and blast furnace. Facing the future, to improve the resource and energy utilization efficiency, adopt low-carbon energy saving technology and advanced technical process base on the fundation of existing technology. For the traditional technologies such as sintering and blast furnace, advanced technologies should be further researched and applied to improve production efficiency and reduce energy consumption and carbon emissions. The green and low-carbon sintering technologies should be continue to study and promote, such as low-carbon and thick material layer sintering technology, hydrogen-rich gas spraying technology of sintering material surface, reback sinter ore efficient recovery technology, low temperature sintering technology and hot air circulating sintering technology, to effectively reduce energy consumption and CO2emissions in the sintering process. Make the most of China's concentrate iron ore fine resources to produce pellet, improve the production capacity and output of pellet, and then improve the pellet charging ratio and the comprehensive grade of burden, and effectively reduce the carbon fuel consumption. Increase the blast furnace oxygen enrichment ratio and pulverized coal injection rate, continue to increase the hot blast temperature and reduce the fuel consumption, and improve the blast furnace top pressure and gas utilization ratio. The hydrogen enrichment gas injection to reduce coke consumption, develop and apply the blast furnace top gas recycle injection and CO2 removal and reuse technology (CCUS) in some conditional blast furnaces. The thermodynamic mechanism of carbon-hydrogen coupled reduction in blast furnace ironmaking process is researched and analyzed, the reduction capacity of solid carbon, CO and H2 under different temperature zone in blast furnace is discussed, and the coupling and matching of direct reduction and indirect reduction is the technological core of the lowest fuel ratio are prosoed. The technical feasibility and economy of full hydrogen or enriched hydrogen injection into blast furnace are discussed. These comprehensive technical measures have a significant effect on further reducing the carbon consumption and reducing the CO2 emission of the blast furnace process. As while as, design advanced and reasonable process system and dissipative structure, optimize the procedure interface technology, and construct a cyber physical system (CPS) to realize the coordinated, efficient, dynamic and orderly operation of ironmaking process. It is also one of the key and common technologies of blast furnace ironmaking process to achieve green and low carbon, and has wide applicability and significant application effect.
