摘要

摘要: 利用Roscoe方程，結合FactSage的多元多相平衡計算和純液相渣黏度計算功能可對含固相熔渣的黏度進行計算.本研究針對基于銅冶煉渣的FeO-SiO₂-Fe₃O₄-CaO-Al₂O₃-MgO系，首先根據相似爐渣的黏度測定值對Roscoe方程中的參數進行擬合，同時驗證了該方法在計算所研究體系時的準確性.基于所得的計算模型考察不同組分含量對平衡相組成及黏度的影響規律，并總結獲得合理的渣型配比.當爐渣中各組分的質量分數分別控制在FeO 40%~60%、SiO₂ 25%~40%、Fe₃O₄ 0%~15%、CaO 0%~10%、Al₂O₃ 0%~8%和MgO 0%~4%時，可在冶煉過程中得到流動性較好、固體量較少的熔渣.

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.
