Abstract
The viscosity and structure characteristics of FeO-SiO2-V2O3-TiO2-Cr2O3 systems as the main composition of V-slag were investigated with different Cr2O3 and TiO2 contents using the rotating cylinder method and Raman. The results showed that the viscosity was below 3.5 Pa sat 1540 K, and the polymerization degree of the silicate structure was lower than the main monomer structure (Q°) in FeO-SiO2-V2O3 system. With the induction of Cr2O3 to FeO-SiO2-V2O3 system, the viscosity obviously increased ( 3.5 Pa sat 1770 K), with the polymerization degree of molten structures enhanced drastically as formation of a chain structure (Q2 and the O-Cr-O band) and a sheet structure (Q3). With the further induction of TiO2 to the FeO-SiO2-V2O3-Cr2O3 system, the viscosity was 3.5 Pa sat 1630 K, and the polymerization degree became weaker as the forms of discrete Si-O-Ti and Ti-O-Ti decrease to Q3 in a sheet structure.
