摘要在生产运营阶段，预热器旋风筒顶部耐火材料有块状脱落，造成下料管堵塞。现场观察，部分锚固件与耐火材料结合位置有严重腐蚀。针对这一现象，对锚固件失效、耐火材料施工中的质量控制、工艺设计和生产操作等影响因素进行了分析研究。结果显示，使用环境中含量较高的氯元素对锚固件产生了严重的高温腐蚀，良好的施工质量有助于隔断氯元素与锚固件表面的接触。

Abstract: During the production and operation, the discharge pipe was blocked by the collapsed refractory from the top of preheater C5 cyclone. On-site observation revealed that there was serious anchor corrosion in the integrated area with refractory materials. Research analysis was conducted on anchor corrosion, quality control during refractory material construction, process design and production operation, and it turned out that serious high temperature corrosion on anchor was caused by high chlorine in its environment and high construction quality would help isolate chlorine from the anchors as well.

Key words: cyclone refractory anchor high temperature corrosion
