Prediction of Iron Ore Sinter Strength Using Statistical Technique

24/01/2020As the alumina content increases, more alumina will dissolve into the lattices of hematite, SFCA and the glass phase, causing a decrease in the strength of the sinter. An increase in alumina content in sinter increased columnar shaped SFCA phases, but decreased needle shaped SFCA-1 which is beneficial to high sinter strength.
