| 摘 要： | 为了明确B2O3对高铝低镁渣稳定性的影响，基于现场高炉渣的实际成分，通过熔体物性测定仪、Factsage软件、XPS光谱分析了B2O3对炉渣粘度和炉渣微观结构的影响。结果表明：随着B2O3含量的增加，炉渣粘度降低；当炉渣温度低于1360℃时，炉渣随着B2O3的增加稳定性增强；炉渣温度为1216℃， B2O3质量分数2.0%时，炉渣的稳定性最好。随着B2O3含量的增加，炉渣的液相区逐渐向MgO的区域扩大, B2O3的加入不仅改善了MgO含量过高引起的炉渣难熔现象，同时提高了炉渣在二元碱度波动时的稳定性。

| Abstract: | In order to clarify the impact mechanisms of B2O3 on the stability of high aluminum and low magnesium slag, based on the actual composition of blast furnace slag in the field, the viscosity and microstructure of slag were investigated by the high-temperature melt properties tester, Factsage software and XPS spectroscopy. The results showed that slag viscosity decreases with the increase of B2O3 content and the stability of slag increases with the increase of B2O3 when the slag temperature is lower than 1360℃.The slag stability is the best when the slag temperature is 1216℃ and the content of B2O3 is 2.0%.The liquid region of slag gradually expands to the MgO region with the increase of B2O3 content, The addition of B2O3 not only improves the refractory phenomenon of slag caused by excessive MgO content, but also improves the stability of slag when the binary alkalinity fluctuates. |
