| 摘 要： | 阐述了应力腐蚀和冲刷腐蚀机理，提出了适用于热轧钢卷强制冷却过程出现的应力腐蚀现象的滑移－－锈蚀理论，可以很好地解释热轧钢卷冷却后出现的腐蚀缺陷，采用ANSYS有限元分析热轧钢卷强制冷却过程的热应力状态，说明在腐蚀缺缺陷区域存在100MPa以上的拉应力，诱发了热轧钢卷的应力腐蚀。

| Abstract: | Based on the stress corrosion, erosion mechanism and slippage-rust theory suitable to the stress corrosion of hot rolled coil during forced cooling, the coil corrosion defects are explained. The hot stress status of the hot rolled coil during forced cooling was simulated with ANSYS FEM software, and the result showed that the tension stress of more than 100 MPa is reached in the region of corrosion defects and the stress corrosion of hot rolled coil is induced. |
