WebSep 8, 2024 · The most harmful effect of alumina is to worsen the RDI (reduction degradation index) value of sinter. RDI value increases as the alumina content rises. It is seen that within a 10 % to 10.5 % CaO content range, an increase of 0.1 % in the alumina content raises the RDI by 2 points. WebMar 1, 2024 · In order to improve the RDI property of sinter under certain MgO contents, the effects of fine MgO-bearing flux on the strength of sintered samples before and after reduction in three systems (Fe 2 O 3-MgO, Fe 2 O 3-MgO-CaO, and Fe 2 O 3-MgO-CaO-SiO 2) were investigated in the present work. The experimental results show that (1) in the three ...
