Steel pellets are made from iron ore powder with additives such as limestone, dolomite, olivine and binder bentonite. The addition of these additives and adhesives, in addition to preventing a large amount of gas produced by the evaporation of water from tending to rupture during the initial stage of heating, can also increase the strength of ...

The iron ore, pellets and sinter are reduced which simply means the oxygen in the iron oxides is removed by a series of chemical reactions. These reactions occur as follows:. 1) 3 Fe 2O3 + CO = CO2 + 2 Fe3O4. Begins at 455° C. 2) Fe 3O4 + CO = CO2 + 3 FeO. Begins at 595° C. 3) FeO + CO = CO 2 + Fe. or.
