摘要
采用热力学计算软件FactSage的Phase Diagram模块和Equilib模块对含钛钢渣熔点进行理论研究,并通过熔点实验对研究结果进行验证.研究发现：对于碱度R〈1.5的渣系,当TiO2质量分数小于13%时,TiO2对熔点影响较小;当TiO2质量分数大于13%时,TiO2提高熔点.对于R〉1.5的渣系,Al2O3质量分数为25%-35%时,TiO2的质量分数超过1%可显著提高渣系熔点.
The melting point of titanium-containing steel slag was theoretically calculated using the Phase Diagram module and the Equilib module of thermodynamic calculation software FactSage,and the calculation result was verified by melting experiments.It is shown that,for a slag system with the basicity below 1.5,when the mass fraction of TiO2 is less than 13%,TiO2 has little effect on the melting point of the slag,and while the mass fraction of TiO2 is over 13%,TiO2 can increase the melting point.For a slag system whose basicity is over 1.5 and mass fraction of Al2O3 is between 25% and 35%,when the mass fraction of TiO2 is more than 1%,TiO2 can significantly increase the melting point of the slag.
