摘　　要：本文研究了工业闪速炉渣和贫化电炉渣的物理化学性质。采用目测变温法测定了二者的熔点;采用气泡最大压力法(BMP法)联合测定了二者的密度和表面张力;采用内圆柱体转动法测定了贫化电炉渣的粘度系数,并计算出了其在低温及高温区间的粘滞活化能。 基于有关理论和文献,本文对炼铜炉渣的化学组成与其物理化学性质之间的关系作出了合理解释,获得了有工业应用价值的结论。The physico-chemical characteristics of slags of Flash Smelting Furnace and of Depletion Electric Furnace have been investigated. The melting points of these two slags were measured respectively by observing their shape change with temperature, the densities and surface tension of these slags we re measured with BMP method. The viscosity of the slag of Depletion Elec tric Furnace with internal cylinder traversing method and the viscosity acti vity energies at low temperature and high temperature were calcul...
