摘    要：在模拟反射炉和电炉熔炼冰铜的实验中,用X射线电视装置研究了铜冰铜熔炼时的各种物理现象。炉料在熔炼时所发生的变化均记录在电视录像磁带及X光胶片上。利用渣锍两相之间界面张力的数据计算了体系的浮游系数和膜系数。讨论了熔融硫化物对固体炉料的浸染,泡沫渣的形成条件,冰铜液滴与气泡在渣中的行为以及它们对金属在渣中损失的影响。

Abstract: The technique of X-ray radiograph video was used to study the physical phenomena in experiments simulating copper matte smelting in reverberatory or electric furnaces. The image of the charges in the process of smelting at high temperature was recorded on video recorder tape or X-ray film.The flotation coefficient and film coefficient of the copper matte-slag system were calculated fromthe surface tension of slag and matte together with the interfacial tension between slag and matte.Spreading of molten sulphide, foaming and stability of foam, behaviour of bubble and matte drop inslag, and its effects on the loss of metal in slag were discussed.
