WebNov 1, 2010 · Under laboratory conditions, a study on the RDI and RI (reduction index) of sinter was proposed, in which the sinter was immersed in solutions with different types and concentrations. In order to study the mechanism of CaCl 2 effect on the RDI and RI of sinter, analysis based on the methods of IR spectra, SEM and chalcography was adopted. WebMar 20, 2024 · Sinter with very high RDI generates fines that would lower the permeability in the upper part of the blast furnace leading to higher fuel consumption in the iron making process. Sinter with very low RDI would have lower reducibility and once again increase the fuel consumption in the blast furnace.
