The principle of aluminum box correction is to shorten longer fibers and elongate shorter fibers through external force or local heating, and finally make the fiber lengths of each layer tend to be consistent or meet our required fiber lengths, thereby eliminating deformation or reducing deformation to the specified range.
Various correction methods should be selected according to the structural characteristics, deformation forms, workpiece size, and other different situations of their components during on-site use. If necessary, a comprehensive correction method combining multiple correction forms should also be adopted. Flame correction is the most widely used method, which has the best deformation correction effect for large components and components with high strength. However, flame correction is also a difficult correction method to master, such as improper heating position, temperature control, and cooling method, which can cause new and larger deformation of components, and even lead to product scrapping. Therefore, in addition to having rich practical experience, flame correction operators also need to master the heat treatment performance of aluminum alloys.
