Reduction of Solid Fuel Consumption in Sintering of Indian ...

impart beneficial properties of strength and reducibility to fluxed sinter has been accepted [9]. A majority of installation in India, guided by the blast furnace slag requirement, operate around sinter basicity(CaO /SiO2) 2 which is possibly not conducive with regards to degradation of sinter during reduction [10].

The strength parameters of sinter namely, Tumbler Indexes (TI), Reduction-Degradation Index (RDI) and Reducibility Index (RI) are key properties of sinter that influence the performance of blast furnace when used as burden. The contributing factor to the sinter quality could be the mineralogical composition of the sinter which is decided by the sinter chemistry and other process parameters.
