The composition of a slag system has been shown to be particularly important and influential for the new technology of electroslag remelting withdrawal process. The oxidation of the GH984G alloy elements, in contact with different contents of CaF₂–CaO–Al₂O₃–MgO–TiO₂–SiO₂ in various slag systems, has been investigated in the present study by performing slag–metal equilibrium experiments and ion and molecule coexistence theory analysis. The results show that CaF₂ and MgO have only a minor effect on the oxidation rates of Al and Ti in the GH984G superalloys. However, it was found that SiO₂ would intensify the oxidation degree of Al and Ti, and Al was found to become easier oxidized than Ti. Moreover, CaO was found to reduce the activity of SiO₂ and, thereby, also the oxidation degree of Al and Ti. Also, TiO₂ was found to reduce the oxidation rate of Ti and instead increase the oxidation rate of Al. Finally, the effect of Al₂O₃ on the oxidation of Al and Ti was observed to be opposite to that of TiO₂. The calculated results were found to be in good agreement with experimental measurements. Moreover, viscosity experiments showed that CaO would rapidly increase the viscosity of the slag at low temperatures, and that the viscosity of the slag would increase with an increase in SiO₂ content.

炉渣系统的组成已被证明对电渣重熔回收工艺的新技术特别重要和影响。GH984G 合金元素与不同含量的 CaF ₂ –CaO–Al ₂ O ₃ –MgO–TiO ₂ –SiO ₂接触时的氧化反应在本研究中通过渣-金属平衡实验进行了研究以及离子与分子共存理论分析。结果表明，CaF ₂和MgO 对GH984G 高温合金中Al 和Ti 的氧化速率的影响很小。然而，发现 SiO ₂会加剧 Al 和 Ti 的氧化程度，发现 Al 比 Ti 更容易被氧化。此外，发现CaO降低SiO ₂的活性，从而也降低Al和Ti的氧化度。此外，发现TiO ₂降低了Ti的氧化速率，反而增加了Al的氧化速率。最后，观察到Al ₂ O ₃对Al和Ti氧化的影响与TiO _{2 的作用}相反。发现计算结果与实验测量非常吻合。此外，粘度实验表明，CaO 在低温下会迅速增加渣的粘度，并且随着 SiO ₂的增加，渣的粘度会增加 内容。
