    OverviewHistoryProcessAdvantagesSee also

    Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel.

  • The Sintering Process of Iron Ore Fines – IspatGuru

    Sinters are classified into acid sinter, self-fluxing sinter, and super fluxed sinter. Self-fluxing sinter has sufficient content of CaO (lime) in it which is required to flux its acid components (SiO2, and Al2O3). Super-fluxed sinter has additional content of CaO for fluxing of the acid components introduced in the blast furnace through other burden materials. In case of self-fluxing and ...
