Production of perfect sinter-Need for blast furnaces

This paper presents a number of factors influencing Sinter Quality like particle grain size which relates the FeO content in sinter, the CaO/SiO₂ ratio of the sinter raw mix, chemical composition of the raw materials, especially with respect to the gangue content (SiO₂, MgO, Al₂O₃), interstitial water. It relates sinter-Plant Operational Parameters on Sinter Quality by focusing on effect of homogeneous sinter raw mix of high permeability on fuel consumption for the sintering process, increased sintering time on the mean diameter of the sinter product, effect of the suction pressure on productivity of the sinter plant, the ideal positioning of the burn through point. The study depicts the influence of Sinter-Plant Equipment on Sinter Quality and Quantity, are also discussed addition of burnt lime in sinter-mix oil, sintering process of iron ore fines. The result found have been encouraging with significant increase in productivity, reduces solid fuel rate, lower consumption of fossil fuel and better strength along with higher reducibility.
