摘　　要：对由ANF-6演化而成的CaF2-CaO-Al2O3-SiO2-MgO渣系的电导率进行了测试研究,得到渣中各主要成分和温度对熔渣电导率的影响规律及影响程度,并经回归分析,得到了回归方程。研究结果表明,随着渣中Al2O3、SiO2含量的增大,渣的电导率不断降低。随着CaF2、CaO和MgO含量的增大,渣的电导率显著升高,而且渣中各成分对重熔渣电导率影响的程度为:CaF2>SiO2>Al2O3>MgO>CaO。The electrical conductivity of molten CaF2-CaO-Al2O3-SiO2-MgO slag originated from ANF-6 was investigated,and how the different compositions of CaF2-CaO-Al2O3-SiO2-MgO slag system and temperature affect the electrical conductivity was revealed.Furthermore,the regression equation was suggested.The results show that electrical conductivity of CaF2-CaO-Al2O3-SiO2-MgO slag system lowers gradually with the increasing mass fractions of Al2O3 and SiO2,and rises with increasing mass fractions of CaF2,CaO and MgO.The effects of CaF2,CaO,Al2O3,SiO2,MgO on electrical conductivity are as follows： CaF2SiO2Al2O3MgOCaO.
