摘要
通过对Q2 35地脚螺栓的化学成分、金相组织、夹杂物和外观形貌的分析 ,认识到地脚螺栓产生断裂的原因是 :数量多、尺寸大的夹杂物 ,在拉应力作用下产生微裂纹 ,进而发生断裂。
The composition, microstructure, inclusion morphology and appearance of the foundation bolt made from Q235 steel were analysed.The results shows that the crack of the bolt is attributed to the formation of the inclusion with large quantity and size,which result in microcrack by tension stress, then fracture.
