摘　　要：玻璃溢流下拉法成型工艺中玻璃组分与溢流砖的匹配性至关重要。通过静态侵蚀实验和界面分析,研究不同组分锂铝硅玻璃对锆英石溢流砖的侵蚀性。实验结果表明:锂铝硅玻璃组成中氧化钠含量对锆英石溢流砖的侵蚀影响显著,氧化钠含量越高,锆英石分解温度越低;相同的玻璃组成,实验温度越高,玻璃对溢流砖的侵蚀越严重。The match between the glass compositions and the overflow refractory is crucial for glass fusing draw processes.Static experiments and interface analysis were carried out to study the erosion influence of different components of lithium aluminosilicate glass on zircon overflow refractory.The experimental results show that the influence of sodium oxide content on the erosion of zircon overflow refractory is most significant.The higher the sodium oxide content,the lower the zircon breakdown temperature.As the same glass composition,the higher the temperature,the worse the erosion.
