Sažetak

Melting behavior is the precondition of liquid phase reaction, which is the foundation of sinter consolidation. Melting property measurement and sinter pot test were adopted to determine the melting temperature and strength of sinter with 13 % and 40 % vanadium-titanium ore addition at different CaO/SiO2 ratio. The results showed that, the increasing CaO/SiO2 ratio positively influences the melting property. Due to the difference of TiO2 content, the influence of increasing CaO/SiO2 ratio on strength appears in different curves which are not the same as prediction. The sinter strength variations were not only influenced by melting property, but also by mineral texture. The influences of TiO2 on melting property, strength, mineral texture especially SFCA were still needed a further study.
