TFe对钒渣熔体物化性质影响的研究
Study on the effect of TFe on the physicochemical properties of molten vanadium slag
摘要
Abstract
The viscosity and melting characteristics of the FeO-SiO2-V2O3-TiO2-MnO-CaO-MgO sys-tem were investigated by rotating column method and hemispherical method,and the influence of total iron content(TFe)on the physicochemical properties of vanadium slag melts was discussed.Combined with X-ray diffraction(XRD)and scanning electron microscopy(SEM)analysis,the phase precipita-tion of vanadium slag at high temperatures and its relationship with viscosity and melting point were in-vestigated.The results showed that with the increase of TFe content,the slag flow temperature de-creased while the viscosity increased,and there was an obvious transition point of viscosity when tem-perature decreased.Above this critical temperature,TFe content had negligible effect on the viscosity of the slag,while below the transition temperature,the viscosity of the vanadium slag increased dramatic-ally with the increase in TFe.At the vanadium extraction temperature of 1 350 ℃,the precipitated phase of the slag was mainly a high melting point spinel phase,and the increase in TFe content promoted the precipitation of the spinel phase and the single particle became larger,resulting in a sudden increase in the viscosity of the melt as well as the melting temperature.The present work would provide a theoretic-al basis to some extent for optimizing the physical and chemical properties of vanadium slag.关键词
