CaO－B<sub>2</sub>O<sub>3</sub>熔渣中氮的熱力學計算模型

CaO－B₂O₃熔渣中氮的熱力學計算模型

摘要: 根據爐渣結構的共存理論,推導了CaO-B₂O₃渣系熱力學計算模型,并且理論計算的CaO,B₂O₃的作用濃度與實測的活度值非常一致。由此說明了該模型的合理性。在此基礎上,找出了爐渣結構與渣中氮含量的關系,并分析了其有關的物理意義。研究結果認為:渣中氮含量與爐渣結構密切相關.

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.
