Reduction of solid fuel consumption in sintering of Indian iron ore
The present investigation deals with the sinterability of Goa (India) iron ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its MgO were varied in the 2.0 to 2.5 and 1.5 to 3.0 range. The effect of process variables on the quality parameters of sinter namely, tumbler index (TI)...

| description | The present investigation deals with the sinterability of Goa (India) iron
ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its
MgO were varied in the 2.0 to 2.5 and 1.5 to 3.0 range. The effect of process
variables on the quality parameters of sinter namely, tumbler index (TI),
reduction-degradation index (RDI) and reducibility index (RI) as well as the
productivity of sinter was studied. The studies have shown that the
consumption of coke (C: 74%) was inter-influenced by the sinter basicity and
its MgO content. Increasing the solid fuel consumption was not a viable
solution to improve TI and RI simultaneously. The content of coke in the mix
could be reduced to as low as 4% through `low temperature sintering? at the
balanced return fines recirculation (~ 33 wt. percent). The sintering indices
in terms of productivity of sinter and its quality improve quite
significantly at a higher sinter basicity (CaO/SiO2 ~ 2.5) and its lower MgO
content (1.5%).
