Break the aluminum plate

The aluminum sheet broke during the stretching process. Usually, it is caused by poor melt quality, internal slag inclusions, severe looseness, etc.

The unreasonable distribution of hot rolling pass processing rate makes the deformation of the surface layer and the core of the aluminum plate uneven, resulting in serious residual cast excessive interlayer in the core, which may cause tensile fracture.

Due to defects on the edges of hot-rolled aluminum sheets, such as cracks, cracks, and slag inclusions, tensile fractures may occur.
