Measurement and simulation validation of DEM parameters of pellet
In numerical simulations of the blast furnace, the discrete element method (DEM) is a quite novel method. The accuracy of physical parameters of the method is a key issue for the reliability of the results. In this study, we first measured the parameters describing the interaction between pellets, sinter and coke, as well as between these …

Pellet is made from iron concentrate with a nickname of "smoothing pill" because of its round shape and value for the burden permeability inside blast furnace. It is easy to roll under the distribution chute of blast furnace; therefore the blast furnace shape is slimmer when using high pellet ratio and squat for high sinter ratio.

Ore Sinter
Compared with lump ore, sinter and pellets, particularly fluxed pellets, are more porous and reducible with an RI value of often > 65. Lump ores are often less porous and therefore lower in reducibility than sinter and most pellets. The RI value of lump ores varies widely from the middle forties to the low seventies.
