Abstract：The physical essence of blast furnace ironmaking is the process of transforming/converting iron ore into hot metal under the drive and action of carbon energy flow and a series of complex physical and chemical metallurgical reactions, according to the designed process network and operation procedures. Carbon is not only an energy-driven source of the iron ore reduction process, but also an important non-metallic alloy element to generate hot metal. Facing the development situation of global "carbon peak" and "carbon neutrality", traditional blast furnace must be improved, optimized and innovated on the basis of existing technology, and strive to achieve multiple goals such as low carbon, high efficiency, greenization and intelligentialization. Meanwhile, the future blast furnace must start with the functional design, equipment design and process design, adhere to the new development philosophy of energy saving, emission reduction, low carbon and greenization. Through process optimization, structure optimization and technology development, the traditional blast furnace will be more suitable for the change of burden composition and fuel structure, reduce coke consumption and dependence, establish a new dissipation structure system with reduced energy input of carbon, and thus realize the engineering evolution and technology development of low carbon and high efficiency.
