为了系统研究五元含氟渣系各组元对熔渣电导率的影响,根据5因素2次正交旋转回归法设计渣系,使用RTW-10熔渣物性测定仪,采用交流4探针法,测定了1 600℃下各渣系的电导率;研究了各组元对含氟渣系电导率的影响。结果表明:当CaF2的含量(质量分数,下同)在10%～75%时,随着Al2O3和SiO2含量的增加电导率逐渐减小,而随着CaF2、MgO和CaO含量的增加电导率逐渐增大;在w(Al2O3)=20%、w(MgO)=10%和w(CaF2)=50%时,当w(CaO)小于7%,随着w(SiO2)的递增电导率逐渐减小,而当w(CaO)大于7%时,随着w(SiO2)的递增电导率逐渐增大;在w(SiO2)=10%、w(MgO)=10%和w(CaF2)=50%时,当w(Al2O3)小于11%时,随着w(CaO)的递增电导率逐渐减小,当w(Al2O3)大于11%,随着w(CaO)的递增电导率逐渐增大。
In order to systematically study the influence of each component of the five-component fluorine-containing slag system on the slag conductivity, slag system was designed based on 5-factor and 2-order orthogonal rotation regression method. RTW-10 slag physical property analyzer was used. , The conductivity of each slag system was measured at 1 600 ℃. The influence of each component on the conductivity of the fluorine-containing slag system was studied. The results show that the conductivity decreases gradually with the increase of Al2O3 and SiO2 contents when the content of CaF2 (mass fraction) is 10% ~ 75%, while the conductivity gradually increases with the increase of CaF2, MgO and CaO content ; When w (CaO) is less than 7%, w (CaO) = 10% and w (MgO) = 10% , And the conductivity increases gradually with the increase of w (SiO2) when w (CaO) is more than 7%; when w (SiO2) = 10%, w (MgO) = 10% and w (CaF2) %, The electrical conductivity of w (CaO) gradually decreases as w (Al203) is less than 11%, and the conductivity increases gradually with w (CaO) when w (Al203) is more than 11%.
