摘要
根据炉渣结构的共存理论和相图，推导了ＣａＯＢ２Ｏ３和ＦｅＯＦｅ２Ｏ３Ｂ２Ｏ３渣系的热力学计算模型。结果表明：（１）理论计算的ＣａＯＢ２Ｏ３渣系的作用浓度ＮＣａＯ及ＮＢ２Ｏ３与实测的活度ａＣａＯ及ａＢ２Ｏ３一致；（２）理论计算的ＦｅＯＦｅ２Ｏ３Ｂ２Ｏ３渣系的氧化能力ＮＦｅｔＯ与实测的炉渣ＦｅｔＯ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。
Based on the coexistence theory of slag structure and phase diagrams, thermodynamic calculating models have been deduced for CaO B 2O 3 and FeO Fe 2O 3 B 2O 3 slag melts. It is shown from the calculated results that: (1) The calculated mass action concentrations of CaO, B 2O 3 are in good agreement with the measured activities of their units. (2) For the FeO Fe 2O 3 B 2O 3 slag melt, the calculated N Fe t O is consistent with the experimental a Fe t O . Therefore, the above mentioned models are reasonable.
