Carboncontaining pellets were prepared with the carbonized product of agricultural wastes and iron concentrate, and an experimental study on the direct reduction was carried out. The experimental results demonstrated that carboncontaining pellets could be rapidly reduced at 1200 to 1300°C in 15 minutes, and the proper holding time at high temperature was 15 to 20#x2009;min.
Pellets should have a mean product pellet compressive strength value of minimum 250 kg/pellet with the <150 kg/pellet fraction less than 5% industrially. Porosity: Porosity of typical industrial wet and dry pellets should be in the range of 31 36% whilst it should be 18 32% for fired pellets.
