基于离子和分子共存理论的炉渣氧化能力表征
Expression of oxidation ability for metallurgical slags based on the ion and molecule coexistence theory
摘要
Abstract
The defined oxidation ability of metallurgical slag based on the ion and molecule coexistence theory (IMCT), i.e., the comprehensive mass action concentration of iron oxides NFetO, was verified by comparing the calculated NFet O and the reported activity of iron oxides aFet O in selected 14 slag systems. To calculate NFet O in the selected slag systems, a thermodynamic model for calculating the mass action concentrations of structural units in CaO-SiO2-MgO-FeO-Fe2O3-MnO-Al2O3-P2O5 type slag systems, i.e., the IMCT-Ni thermodynamic model was developed. NFetO in the other 13 slag systems can be obtained by simplifing this IMCT-Ni. It is shown that the defined comprehensive mass action concentration of iron oxides NFet O is more accurate than the measured activity of iron oxides aFet O in characterizing the oxidation ability of the selected Fet O-containing slag systems.关键词
