Cold

Aluminum Cold
Cold rolling reduces hot rolled strip to its finished thickness whilst producing a smoother surface finish. 

It takes more energy to roll cold metal than that softened by heating, so an efficient process reduces production costs. Cold mills can typically operate at speeds up to 7,000fpm/ 2,100 mpm, making automated inspection essential.

Cold-rolled aluminum is subject to many further operations during the manufacturing process, all of which benefit from high levels of surface inspection and defect monitoring to ensure product quality.

AMETEK Surface Vision delivers trusted highly accurate solutions for continuous processes, maintaining line speeds and rapidly detecting defects. Automation options provide reliable inspection even at fast line speeds.

APPLICATION NOTE
Aluminum Cold Mill - Application Note (EN)ALUMINUM COLD MILL
Cold rolling is an important part of the manufacturing process for thin aluminum strip and sheet. Effective quality control at this stage, by monitoring dents, scratches and other surface defects, can protect from claims and reduce costs throughout the production process.

  • Applications +

    • Aluminum Annealing
      Annealing

      After or between cold rolling operations coils are passed through an annealing line to relieve stresses. It's important that defects are not introduced at this stage, requiring accurate and reliable inspection.
