【摘要】 运用高温强度理论和近年来研究成果，对某厂超期服役的焦炭塔材料进行了全面的理论分析和试验研究，得出了蠕变疲劳交互作用是焦炭塔的主要失效形式，焦炭塔最薄弱的部位是塔体下部的焊缝区域。为进一步评定焦炭塔剩余寿命提供了可靠保证。更多还原

【Abstract】 The material of the coking column is researched using the theory of ho temperature strength.The resultsshow that the interaction of creep fatigue is the primal failure mode for the coking column and the most dangerous place islocated at the welded zone of its lower part.There provide the scientific basis for the valuation of the residual life of thecoking column.更多还原
