【摘要】 为使红格钒钛磁铁矿金属化球团熔分过程中的含铬熔分钛渣具有良好流动性,从而有利于渣金分离的顺利进行,本文研究了Cr₂O₃对含铬熔分钛渣黏流特性的影响。采用半球法和旋转柱体法分别测量了不同Cr₂O₃含量下含铬熔分钛渣的熔点和黏度。可以发现,随着Cr₂O₃含量的增加,含铬熔钛渣的熔点和黏度逐渐增加。此外,含铬熔分钛渣黏流活化能的变化趋势与其黏度的变化趋势一致。更多还原

【Abstract】 In order to obtain the good liquidity of Cr-containing molten titanium slag and optimize the slag-metal separation in melting separation process of Hongge vanadium titanomagnetite metallized pellet, the influence of Cr₂O₃ on the viscous flow behavior of Cr-containing molten titanium slag was investigated in this work. The melting and viscosity properties were studied by hemisphere method and rotating cylinder method, respectively. The results showed that the melting temperature and viscosity both increased with the increase of Cr₂O₃ content. The trend of activation energy for viscous flow and the measured values of viscosity were identical.更多还原
