At present, most of the iron-bearing raw materials used in blast furnace ironmaking are high alkalinity sinters, oxidized pellets and lump ore. However, with the increasing consumption of global iron ore resources, the development of low-carbon ironmaking technology and the efficient utilization of blast furnace ironmaking resources, etc., the ratio mode of blast furnace charge has gradually moved towards diversified development. Compared with conventional sintering and pelletizing processes, the cold-pressed iron ore pelletizing process has strong adaptability to raw materials, as well as flexible and simple processes, and can reduce the energy consumption of the preparation process, which is a supplement to the iron-containing charge of blast furnace. The metallurgical performance of cold-pressed iron ore pellets is mainly described, the influence of cold-pressed iron ore pellets on blast furnace smelting and its energy saving and emission reduction effects is analyzed. The results show that the metallurgical performance of cold-pressed iron ore pellets can basically meet the needs of blast furnace smelting, and the production of 1 t of pig iron using this pellet can theoretically reduce CO₂ emissions by about 522 kg.
