ABSTRACT

A thermodynamic calculation model of phosphorus distribution ratio between CaO–FeO–MgO–SiO2–MnO–TiO2–V2O5–P2O5 slags and molten metal has been developed based on the ion and molecule coexistence theory (IMCT). The calculated phosphorus distribution ratio shows a good agreement with the measured ones by the data of industrial trial, which proves the reliability of this model. Therefore, the model is used to study the effects of TiO2, V2O5, slag basicity, FeO, MgO and MnO on phosphorus distribution. The results illustrate that the effects on phosphorus distribution from V2O5 and TiO2 are non-negligible and they are almost the same, slag basicity and FeO have the most significant effects on phosphorus distribution, while MgO and MnO have the least.

基于IMCT的各种组分对CaO-FeO-MgO-SiO2-MnO-TiO2-V2O5-P2O5渣中磷分布的影响

摘要

基于离子和分子共存理论(IMCT)建立了CaO-FeO-MgO-SiO 2 -MnO-TiO 2 -V 2 O 5 -P 2 O 5炉渣和熔融金属之间磷分布比的热力学计算模型. 经工业试验数据计算得到的磷分配比与实测值吻合较好,证明了该模型的可靠性。因此,该模型用于研究TiO 2、V 2 O 5、渣碱度、FeO、MgO和MnO对磷分布的影响。结果表明,V 2 O对磷分布的影响5和 TiO 2不可忽略且几乎相同,渣碱度和 FeO 对磷分布的影响最显着,而 MgO 和 MnO 的影响最小。
