摘 要:通过对光学玻璃电熔窑的实际观测,研究了光学玻璃对含锆耐火材料侵蚀作用.在熔窑的不同关键部位,选取有关耐火材料进行SEM测试,通过熔窑不同部位的耐火材料受高温玻璃液侵蚀的程度,分析了光学玻璃对锆耐火材料侵蚀机理与行为过程.结果表明:熔窑的熔化部耐火材料的受侵蚀程度较小,流液洞与供料道处耐火材料的受侵蚀程度最为严重,上升流道壁砖的竖缝处有严重的耐火材料侵蚀.AZS耐火材料在与高温玻璃液的接触中,形成了成分相互扩散→溶解→再扩散→再溶解的往复循环过程.
This paper studied the erosion effect of optical glass on zirconium refractory by observing the actual operation of optical glass melting furnace. By SEM measurement the erosion of high temperature molten glass on the refractory materials in different key parts of the furnace was studied. Erosion mechanism and behavioral process of optical glass for zirconium refractory was analyzed. According to the results, erosion of refractory on melting section was relatively less, and the erosion of refractory of liquid flow holes and feeding channels was extremely severe, as well as perpends of wall bricks of the rising flow channels. In the process of AZS refractory contacting on high temperature molten glass, ingredients went through the cycling process of diffusion → dissolution →rediffusion → redissolution.
