摘要
Due to the special working conditions, work rolls are severely worn during hot temper rolling process, which adversely affects the shape accuracy of the strip. However, most of the existing literature about roll wear concern more about hot rolling than hot temper rolling. In this study, the wear mechanism of the work rolls is analyzed based on numerous measured wear contours and wear characteristic of the work rolls. To reveal the wear evolution laws, a high-precision elastic–plastic finite element method (FEM) analysis of tempering rolling is built using the FEM software ABAQUS. Simulation results show the distribution laws of contact pressure are very consistent with the wear evolution laws. Field application proves that the actual wear of the work rolls shows good agreement with the obtained wear evolution laws, indicating that the wear evolution laws are accurate and reliable. This research has the important theory and application value for the analysis of the influencing factors of roll wear and the improvement in non-uniform wear. © 2018, ASM International.
