摘要
用氧化锆固体电介质浓差电池实验测定了电渣重熔用 CaF_2-Al_2O_3-CaO 系熔渣的氧渗透率。对于与实际重熔时的成分基本相符的这种熔渣,在压力为1 atm 的纯氧气氛下,于1680～1810K 的温度范围内,测得的氧渗透率为3×10^(-19)～1×10^(-17)mool·cm^(-1)·s^(-1);随熔渣铁势的增高,氧渗透率显著增大。
The permeability of oxygen through the molten slag of CaF_2-Al_2O_3-CaO system for electroslag remelting was measured using an oxygen concentration cell with zirconia solid electrolyte.The permeability of oxygen through the molten slag,the composition of which is essentially the same as the practical in the remelting,was obtained to be 3×10^(-19)～10^(-17) mol O_2·cm^(-1)·s^(-1) in the temperature range of 1680～1810K underpure oxygen at 1 atm.The permeability increases considerablly with the iron potential of the molten slag.
