Novel Methodology of Modeling Iron Ore Induration …
agents to create "green pellets", which attain required mechanical strength undergoing thermal treatment within induration furnaces. The thermal treatment causes the pellets to experience various heterogeneous reactions, which provide them with the physical properties for use in blast furnace and/or direct reduction facilities [1] [2].

Modelling of heat transfer in a straight grate pellet …
Straight grate furnaces are widely used for induration of hematite pellets where typically 1%–2% carbon is added to the green mix to help in generating heat by combustion. The quality of the pellets in such reactor varies from top to bottom of the bed as different layers of pellets are exposed to varying thermal and gaseous environments.

Pelletizing Process
Three systems are used for indurating pellets, i.e., a shaft furnace system, a straight grate system and a grate-kiln-cooler system. Shaft furnaces are the most traditional facilities; however, few plants use this system these days because of their limited scale. A straight grate system emerged in the industry soon after the shaft furnaces.
