Iron ore pellets are sintered, centimetre-sized spheres of ore with high iron content. Together with carbonized coal, iron ore pellets are used in the production of steel. In the transportation from the pelletizing plants to the customers, the iron ore pellets are exposed to different stresses, resulting in degradation of strength and in some cases fragmentation. For future reliable numerical simulations...
Hydrogen and carbon monoxide mixtures are reducing agents for main direct reduction (DR) processes. However, sticking of iron ore pellets during reduction always leads to discontinuous operation. In order to evaluate the effects of the temperature, syngas constituents and reduction degree on sticking properties, reduction of iron ore pellets in the presence of H 2 –CO mixtures was conducted...
