An Analytical Way to Comparing the Affective Parameters on Iranian Pellet Strength

Iron ore pellets are the raw materials for direct reduction process of iron ore to sponge iron pellets and is an important step in the iron and steel production chain. Many of the defects in direct reduction and steel making processes could be identify in the iron ore processing stage. Therefore, the purpose of this study was to select the correct suppliers of iron ore pellets for direct reduction units based on criteria affecting the strength of cooked pellets, which played a key role in optimizing the production criteria of sponge iron and ultimately increasing production efficiency in the steelmaking stage which can be very effective. For this purpose, using the hierarchical analysis model, the parameters affecting the strength of pellets have been identified and studied by experts of several iron and steel production units, and finally, for example, several iron ore pellet production plants have been compared and ranked. According to AHP decision criteria, particle size is the most important parameter affecting the strength of cooked pellets.
