用X射线照相座滴法测量了Cu-Fe-S系冰铜与FeO-CaO-SiO_2-MgO系炉渣之间的界面张力。实验结果的相对误差为5-9％。讨论了1200℃下炉渣中FeO/SiO_2的重量比值、渣中CaO,Fe_3O_4,ZnO及CaF_2含量对渣-锍界面张力的影响,考察了冰铜品位、温度与渣-锍界面张力间的关系。计算了渣-锍系的浮游系数和膜系数,对O,Fe由渣相向冰铜相的传输机理作了探讨。
The interfacial tension between FeO-CaO-SiO-MgO system slag andCu-Fe-S system matte was determinated by the X-ray radiograph sessile drop method.The effects of FeO/SiO ratio in the slag, contents of CaO, FeO, ZnO and CaF_2 inthe slag on interfacial tension and the relation of interfacial tension with the gradeof matte and temperature have been studied. The floatation coefficient and film coef-ficient of slag-matte system has been calculated and the mechanism of the transitionof iron and oxygen from slag to matte has also been discussed.
