摘　　要：文章介绍了延迟焦化工艺流程及焦炭塔周期性温度变化的特点,通过分析表明焦炭塔腐蚀主要是高温硫腐蚀,焦碳塔主要破坏形式是低频热疲劳破坏,并提出了一些解决措施及检验方法。The characteristics of delayed coking process and cyclical temperature changes of coker drum are introduced. The analysis concludes that the coker drum corrosion is mainly the high - temperature sulfur corrosion, and the main damage form of the coker drum is low -frequency thermal fatigue damage. Measures and test methods are recommended correspondingly.
