| Abstract: |
| “Flash ironmaking” is a non-blast furnace ironmaking process and engineering technology based on the cross-disciplinary integration, which extends the mature flash smelting process of non-ferrous metallurgical industry to ironmaking. Its goal is to achieve near-zero carbon ironmaking with low energy consumption, low investment and large scale. In this paper, the laboratory and pilot test results of flash ironmaking technology (flash iron for short) were summarized, and the future industrialization of this technology was evaluated. The results show that the flash iron can efficiently treat low-grade complex ore, cancel the raw material pretreatment section such as pellet sintering, spheroidization and coking, achieve zero carbon emission, easy to scale, and realize one-step steelmaking. The comprehensive energy consumption (351 kgce per ton steel) of flash iron is less than that of the blast furnace ironmaking process (553 kgce per ton iron). |
