| 中文摘要: |
| 通过对大型法兰分段下料组焊后严重变形的矫正，明确了热矫正的关键在于建立适当的温度梯度，走出了“高温加热即显功效”的误区，并且归纳出加热温度与矫正角度之间的近似关系式以便指导类似的热矫正过程。 |
| 英文摘要: |
| Based on straightening serious distortion of large-size flange blank of welded subsections, it is clear that the key of hot correction lies in the establishment of proper temperature gradient, out of "high temperature has effect", and the approximate relational expression between heating temperature and corrective angle is summed up to guide similar hot correction. |
