| 摘 要： | 采用金相、扫描电镜等手段对置裂的大型Cr3支承辊断口进行分析。结果表明,辊身心部较高的内应力和坯料锻造时未能使树枝晶充分破碎是造成大型支承辊置裂的主要原因。

| Abstract: | The delayed fracture of large scale Cr3 back-up roll has been analyzed by metallurgical phase and scanning electron microscope.The analysis result shows that,the stronger internal stress at the center of roller body and the trees dendrite has not been completely broken up when blank forging are the main causes of delayed fracture. |
