<p>A low reduction degradation index is desired in Iron ore sinter. Indian iron ore fines contain a high percentage of alumina and this has a deleterious effect of sinter quality, particularly RDI. This invention proposes a method for improving the RDI of sinter by increasing the CaO content and the suction pressure employed during sintering. This combination of sinter CaO and suction pressure helps in controlling RDI by increasing the amount of unassimilated hematite and decreasing the amount of secondary hematite present in sinter.</p> |
