Abstract
The cooling process following hot rolling has a significant effect on the shape quality of a hot-rolled strip. The temperature and stress fields in the cooling process for a 14 mm thick strip with yield strength of 500 MPa grade were analyzed by the finite element method and actual test data, and the relationship between residual stress and shape defects was described. Subsequently, the small-crown rolling process and the coil slow cooling process were investigated. The results indicate that these processes improved the shape quality of the final product significantly.
