摘要

摘要: 利用Roscoe方程，结合FactSage的多元多相平衡计算和纯液相渣黏度计算功能可对含固相熔渣的黏度进行计算.本研究针对基于铜冶炼渣的FeO-SiO₂-Fe₃O₄-CaO-Al₂O₃-MgO系，首先根据相似炉渣的黏度测定值对Roscoe方程中的参数进行拟合，同时验证了该方法在计算所研究体系时的准确性.基于所得的计算模型考察不同组分含量对平衡相组成及黏度的影响规律，并总结获得合理的渣型配比.当炉渣中各组分的质量分数分别控制在FeO 40%~60%、SiO₂ 25%~40%、Fe₃O₄ 0%~15%、CaO 0%~10%、Al₂O₃ 0%~8%和MgO 0%~4%时，可在冶炼过程中得到流动性较好、固体量较少的熔渣.

Abstract: The viscosity of solid-containing slags can be calculated using the Roscoe equation combined with the calculation functions of multi-component & multi-phase equilibria and pure-liquid slag's viscosity in FactSage software. An FeO-SiO₂-Fe₃O₄-CaO-Al₂O₃-MgO system used in copper smelting was studied in this paper. Firstly, the parameters of the Roscoe equation were fitted using the measured viscosities of analogous slag in the literature, and the accuracy of viscosity calculated by the method for this slag system was verified additionally. Then, the effect of slag components' contents on the equilibrium phase-composition and viscosity was investigated based on the calculation model. Accordingly, the reasonable proportions of components in the slag were obtained. When the mass fractions of slag components are FeO 40%~60%, SiO₂ 25%~40%, Fe₃O₄ 0%~15%, CaO 0%~10%, Al₂O₃ 0%~8%, and MgO 0%~4%, the molten slag with good liquidity and fewer solids can be obtained in the smelting process.
