摘要随着篦冷机高温篦板使用量的快速增长，叶片断裂、磨损、弯曲等失效问题日益突出。通过对篦冷机高温篦板失效状态进行分类及原因分析，提出了改进思路，研发了具有更好高温力学性能的新材料篦板，优化了篦板结构，并采用精密（失蜡）工艺及无损RT射线进行了新材料篦板铸造及质量检测。优化升级后的高温篦板在使用一年后，篦板叶片基本无磨损和变形，整体应用情况良好。

Abstract: With the rapid growth of the usage of high-temperature grate plates in grate coolers, failure problems such as blade breakage, wear, and bending had become increasingly prominent. Through classifying and analyzing the failure state of high-temperature grate plates, improvement ideas were proposed. New material with better high-temperature mechanical properties was developed, the structure of the grate plate was optimized, and precision (lost wax) technology and non-destructive RT ray was used for new material casting and quality inspection. After one year of utilization, the optimized and upgraded high-temperature grate plate blades were basically free from wear and deformation, and the overall application was in good condition.

Key words: high temperature grate plate efficient rapid cooling slope technology precision casting quality inspection
