However, the addition of these materials via the sinter plant has been knownto create problems, This study investigates the effect of adding a titanomagnetite to two sintering ore blends, containing 10 and 20'/• pisolitic limonite respectively. The addition of up to 2•/• titanomagnetite did not affect the sintering parameters or sinter quality. Increasing the titanomagnetite levels to greater than 3•1also had no significant influence on sintering but a significant deterioration in sinter RDI was recorded. Resu Its also showed that the deterioration in RDIwas greater for the blend containing more pisolitic limonite. SEM studies carried out on the product sinters found most of the titanium in the glass phase. The mechanical properties of the glass was characterised using indentation fracture mechanics. Although some difficult was experienced, due to the small and disperse nature of the glass, addition studies using artifically manufactured glass indicated that the fracture toughness of the glass decreased with increasing titanium levels, It is postulated that becauseglass in the weakest phase in sinter and is widely dispersed any reduction in its fracture toughness will increase the vulnerability of the sinter to crack propagation, thereby increasing sinter RDl. It is also postulated that increasing the pisolitic level increased melt formation and the dispersion of the glass phase, resulting in a further deterioration in sinter RDI.
