It is found that lump ore has lowest reduction rate in all test conditions, and at lower temperatures iron ore pellets reduce faster than sinter, and this is reversed at higher temperatures. Furthermore, the reduction rate of sinter and iron ore pellets begins to resemble each other at higher temperatures.
The permeability of the sintering process can be significantly improved by the pellet sintering, but the excessive permeability will impact the heat accumulation of the sinter bed. Thus, it is very essential to clarify the influence of the pellet particle size on the heat transfer process of sintering. Therefore, pilot-scale sinter pot tests of pellet sintering with manganese …

Reduction reactions of iron ore between gas and raw material are determined by material bulk, especially radial distribution of pellet/sinter and coke in blast furnace. An appropriate control of material distribution is required to yield a smooth operation with effective performance and an appropriate gas flow at the wall. This paper studies two different DEM packages application for …
Fig. 12 presents the mass percentage distribution of pellets and sinter in the radial direction of the furnace throat when the pellet ratio is 20%, 40%, 60% and 80%, respectively. In the area near the center of the furnace throat, such as the radial positions 1, 2 and 3, the mass percentage of pellets is relatively high which is greater than ...
