摘    要：根据炉渣结构的共存理论和相图，推导了CaO-B₂O₃和 FeO-Fe₂O₃-B₂O₃渣系 的热力学计算模型。结果表明：(1) 理论计算的CaO-B₂O₃渣系的作用浓度 N_CaO及N_B2O3 与实测的活度a_CaO及a_B2O3一致； (2) 理论计算的FeO-Fe₂O₃-B₂O₃渣系的氧化能力N_FetO 与实测的炉渣Fe_tO的活度值相符合。这说明本文提出的 热力学计算模 型是合理的。

Abstract: Based on the coexistence theory of slag structure and phas e diagrams, thermodynamic calculating models have been deduced for CaO-B₂O₃ and FeO-Fe₂O₃-B₂O₃ slag melts. It is shown from the calculated results that: (1) The calculated mass action concentrations of CaO, B₂O₃ are in good agreement with the measured activities of their units. (2) For the FeO-Fe₂O₃-B₂O₃ slag melt, the calculated N_FetO is consistent with the experimental a_FetO . Therefore, the above mentioned mode ls are reasonable.
