3Cr2W8V轧辊失效原因分析

Failure Analysis of 3Cr2W8V Roller

对3Cr2W8V轧辊使用初期开裂失效的原因进行了探讨。经过硬度测试与组织分析、工艺改进及生产使用验证,确定3Cr2W8V轧辊使用早期开裂失效的原因主要为锻造比较小、轧辊组织中存在带状碳化物。

The reasons for early fracture failure of the 3Cr2W8V rolling roller were discussed. After the hardness testmicrostructure analysis, process improvement and production validation, it is ensured that the main causes of early failure of3Cr2W8V rolling roller are smaller forging ratio and banded carbide microstructure.
