摘要
轧辊是轧机的主要变形部件。总结了轧辊材质、主要工作形式及失效方式和轧辊表面处理技术应用概况,具体从激光淬火与重熔技术、激光合金化和激光熔覆3个方面介绍了轧辊激光表面处理(修复)技术的研究和应用现状,并展望了激光表面处理技术修复表面失效轧辊的发展前景。
Rollers are the main deformation tools of rolling mills. Materials of rollers, the main work forms and failure mode, and modification techniques used on roller surface are reviewed. Development and application of laser modification(repairing) techniques used on roller surface are introduced from three aspects; laser quenching and melting, laser alloying and laser cladding. At last, the prospects of applying techniques of laser modification on surface to repair rollers are given.
