| 摘 要： | 对已使用14年,目前发生腰鼓变形的焦炭塔的筒体材质进行了金相检验,发现其珠光体球化达到4级,材质老化程度较大;进行了硬度、厚度、应力、温度测试和应力、最大允许操作压力的校核,确认焦炭塔在厚度和强度方面是安全的,最后判定此焦炭塔的安全等级可以评定为4级,并建议要严格控制焦炭塔的实际使用温度,定期进行现场金相检验,掌握筒体组织珠光体球化的程度,以保证设备的安全运行。

| Abstract: | Metallographic test of the specimen material taken from a deformed wall of a coking tower was performed. Its pearlite spheroidization was found to rank fourth grade, the material aging was severe. Through testing hardness, thickness, stress and temperature as well as checking stress and maximum allowed operating pressure, it was concluded that the coking tower was safe concerning strength and thickness. Finally, the safety of the coking tower was judged to be fourth grade. |
