Ni_3S_2-FeS-Cu_2S冰镍体系的表面张力

Surface Tension of the Ni_3S_2-FeS-Cu_2S ternary Mattes

运用几何模型 (Kohler及Toop模型 )和通用溶液模型 (Chou模型 ) ,由Ni3S2 FeS、FeS Cu2 S和Cu2 S Ni3S2 三个二元边界体系的表面张力计算了Ni3S2 FeS Cu2 S三元系表面张力。计算结果与实验值 (实验误差为± 2 5 % )十分吻合 ,1 4 73K下Ni3S2 FeS Cu2 S冰镍体系的等表面张力曲线有较高的可信度 ,对分析研究镍的闪速熔炼和转炉吹炼过程有重要意义。

Using the geometric models (Kohler and Toop model), as well as general solution model (Chou model), the surface tensions of the Ni_3S_2FeSCu_2S ternary matte were calculated from those of the Ni_3S_2FeS、 FeSCu_2S、 Cu_2SNi_3S_2 pseudobinary systems. The calculated results are in good agreement with the experimental data of which uncertainty is estimated to be ±2.5%. These reliable isosurface tension lines are necessary for the process of flash smelting and converter flowing of nickel and copper.
