Quality Estimation for the Iron Ore Sinter Obtained via ...

This paper reveals that obtaining high-quality sinter, improved or stabilized by its size and strength, is a challenge to be solved by embracing both the formation of sinter with the strong structure and the optimal mineralogical composition of its bonds during the preparation of the sintering blend. The existing technological schemes of iron ore sintering do not allow producing the sinter ...

Rate-Limiting Mechanism in Iron Ore Sintering

Recycling waste gas through the sinter bed has an advantage of saving solid fuel. Depending upon the amount of waste gas recycled and its CO content, an equivalent quantity of solid fuel is saved. FeO is one of the key indicators of fuel needed for sintering; its optimization is critical to the consistency in sinter quality. Sinter pot tests were conducted to identify the effect of varying ...
