Difficulties in producing ultra-wide 3003 aluminum sheet

The primary difficulty in producing ultra-wide 3003 aluminum sheet lies in controlling uniformity during the melting and casting process. Large-sized aluminum ingots are prone to compositional segregation and thermal cracking during the casting process, requiring optimized cooling rates and stirring processes to ensure uniform microstructure.

Secondly, rolling deformation and plate shape control are key challenges. Ultra-wide 3003 aluminum sheet is prone to defects such as edge ripples and center concavity during hot and cold rolling, requiring the use of high-precision rolling mills and dynamic plate shape adjustment systems.

Furthermore, cutting and surface treatment present significant challenges. Ultra-wide 3003 aluminum sheet requires extremely high straightness from cutting equipment, and the surface oxide film spraying must be uniform to prevent color variation and coating detachment.
