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

在CaO基精炼渣中加入BaO和B2O3进行改质,对改质后的精炼渣进行熔化性能和脱硫性能的实验研究.结果表明,BaO可以降低精炼渣的熔点和粘度,有效地改善钢-渣反应的动力学条件,同时增强精炼渣的脱硫能力,当BaO含量为15%~25%时,脱硫率稳定在90%以上;而B2O3对精炼渣的脱硫率无明显影响,可取代CaF2作为助熔剂加入
