In traditional blast furnace iron making, the iron ore is fed to the blast furnace in one of three common forms: Lump, pellets or sinter. All of which are designed (in conjunction with coke) to maintain a porous feed bed in the blast furnace and thus facilitate rapid and uniform reduction of the iron ore (iron oxide) to iron metal.

X – RAY DIFFRACTION ANALYSIS OF IRON SINTER

Producers of iron sinter need precise phase analysis for effective operation supervision. It is not enough to consider only chemical composition, but it is beneficial to know the iron sinter mineralogical composition. Producers can utilize this information for better sinter mechanical properties adjustment and sinter yield improvement.
