AI Technical Summary
Magnesium alloy sheets and strips are prone to stress concentration and cracks at the edges due to their poor plastic deformation capacity during rolling. Existing multi-pass rolling with low reduction rates cannot completely eliminate crack defects, resulting in poor forming quality.
The extrusion block in the shaping device performs directional extrusion on the edge of the strip with longitudinal wave surface, transverse wave surface or coupled wave surface. Different waveform surfaces are matched according to the thickness of the strip. Combined with the speed control of the conveying device and heat treatment, the internal stress is released evenly and the forming quality is improved.
It effectively reduces edge cracks in sheet and strip materials, improves forming quality and processing efficiency, and avoids cumulative errors and surface damage caused by multiple rolling passes.
