CaO－B₂O₃熔渣中氮的热力学计算模型

摘要: 根据炉渣结构的共存理论,推导了CaO-B₂O₃渣系热力学计算模型,并且理论计算的CaO,B₂O₃的作用浓度与实测的活度值非常一致。由此说明了该模型的合理性。在此基础上,找出了炉渣结构与渣中氮含量的关系,并分析了其有关的物理意义。研究结果认为:渣中氮含量与炉渣结构密切相关.

Abstract: On the basis of the coexistence theory of slag structure. the thermodynamic calculating model of CaO-B₂O₃ slag melt was deduced. The agreements between calculated N_CaO, N_B₂O₃ and measured a_cao a_B₂O₃ are well. The relationship of nitrogen solution in CaO-B₂O₃ slag with mass action concentrations of structural units has been suggested and the related physical means are discussed. The nitrogen solution in CaO-B₂O₃ slag is closely connected with the slag structure.
