| Abstract Scope |
The flash iron-making process is expected to be a new iron-making technology due to its nonuse of coke, pellets, sintered ore and extremely high production efficiency. Hydrogen is an excellent reducing agent for flash iron-making with fast reduction rate and none CO2 emission. In this study, the effect of hydrogen concentration and reduction temperature on reduction characteristics of Fe3O4 in a drop tube furnace was investigated using the computational fluid dynamics method. The results show that the Fe3O4 particles can be reduced in seconds. The reduction degree gradually increases with increase of hydrogen concentration and reduction temperature. The maximum metallization ratio can reaches 88.95%. |
