光学碱度在钢铁冶金研究中的应用

APPLICATION OF OPTICAL BASICITY IN THE SYUDY OF FERROUS METALLURGY

阐述光学碱度的概念及理论光学碱度的计算方法,计算了 MO—MCl_2—Fe_xO 渣系的理论光学碱度,研究了理论光学碱度与磷容、Fe^(2+)/Fe^(3+)、同质异能移的关系。发现 MgO-MgF_2、Na_2O—NaF、BaO—BaF_2系的 logCpo_4^(3+)与理论光学碱度呈线性关系。CaO—SiO_2—Fe_2O_3系中 log(Fe^(2+)/Fe_2^(3+))随理论光学碱度的增加而下降。MO—MX_2—Fe_2O_3系中同质异能移与理论光学碱度亦呈线性关系。

The concept of optical basicity and method for calculating the theoretical optical ba- sicity have been elaborated on,the theoretical optical basieity of Mo—MCl_2—Fe_xO(M=Ca,Sr,Ba) slag calculated,and relationship among the theoretical optical basicity,phosphate capacity and Fe^(2+)/ Fe^(3+)isomer shift studied respectively. The results showed that logCPO_1^(3-) was found to have a linear relation with the theortical optical basicity in MgO—MgF_2,Na_2O—NaF,BaO—BaF_2 system;Log (Fe^(2+)/Fe^(3+)) decreases with increasing theoretical optical basicity in CaO—SiO_2—Fe_2O_3 system;and the isomer shift also has a linear relation with the theoretical optical basicity in Mo—Mx_2—Fe_2O_3(M=Ca,Sr,Ba;X=F,Cl) system.
