摘要
针对钛的氧化物比铁的氧化物更难被碳还原,研究不同的组分含量对熔化性温度的影响,对CaO-SiO2-Al2O3-TiO2体系熔化性温度进行研究,运用了Factsage软件来熔化性温度变化。得到以下结论:在熔化性温度区域范围为,CaO的质量分数25.00%~40.00%,SiO2的质量分数22.00%~37.00%,Al2O3的质量分数7.00%~16.00%,TiO2的质量分数15.00%~30.00%。且CaO和SiO2对体系熔化性温度影响相对较大,TiO2和Al2O3对体系熔化性温度影响相对小。随着CaO/SiO2的增大,体系的熔化温度逐渐升高,CaO/SiO2对体系熔化温度的影响较大。
Titanium oxide is more difficult to be reduced by carbon than iron oxide.The influence of different component content on melting temperature was studied.The melting temperature of Cao-Sio2-Al2O3-Tio2 system was studied.Factage software was used to change the melting temperature.The following conclusions are obtained:in the melting temperature region,the mass fraction of Cao is 25.00%~40.00%,the mass fraction of SiO2 is 22.00%~37.00%,the mass fraction of Al2O3 is 7.00%~16.00%,and the mass fraction of TiO2 is 15.00%~30.00%.The influence of Cao and SiO2 on the melting temperature of the system is relatively large,while that of TiO2 and Al2O3 is relatively small.With the increase of CaO/SiO2,the melting temperature of the system increases gradually,and CaO/SiO2 has a great influence on the melting temperature of the system.
