摘要

In this paper, the influence of basicity (CaO/SiO_2) on the viscosity and crystallization characteristics of chromium-containing high-titanium slag was studied. The melting temperature and viscosity were measured by employing the hemisphere and rotating cylinder methods, and the composition and morphology of the crystallized phase were analyzed by X-ray diffraction and scanning electron microscopy-energy dispersive spectroscopy. The results showed that the crystallization sequence during the cooling process was spinel, followed by anosovite. The increased basicity led to enhanced softening, hemispherical, and flowing temperatures of chromium-containing high-titanium slag; however, the viscosity significantly decreased. The basicity obviously affected the crystallized phase composition. Furthermore, anosovite was the dominant crystallized phase and a proper level of basicity was beneficial for titanium enrichment.
