Steel Cold
Surface scale is removed from hot rolled coils before being cold rolled to a finished thickness and then annealed to remove rolling stresses. Most cold rolled coils are further processed to suit each application which often requires additional cold rolling to improve surface quality or adding special surface coatings.

Multi stand tandem cold mills operating at speeds up to 2,000 metres per minute, require reliable high-speed automated inspection systems. This high-volume production environment requires accurate timely data to aid decision making in order to minimise wasted production time, material and cost.

Cold-rolled steel is the result of many different manufacturing processes, all of which benefit from high levels of surface inspection and defect monitoring at each stage to ensure final product quality. 

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

  • Applications +

    • Steel Annealing

      The high-speed annealing process removes stresses created during cold rolling & allows mechanical properties to be developed in advanced steel & tinplate strip by following pre-determined profiles.

    • Steel Decarb Line
      Decarb Line

      Decarburization is a process used in the production of electrical or silicon steel to remove carbon content by annealing. Surface monitoring can detect and classify any defects introduced during this process.

    • Steel Elctric Tin Bath
      Electric Tin Bath

      Thin cold rolled steel is tinplated by immersing in electrolytic plating cells in a continuous process. The quality of the tin coating can be verified by accurate surface inspection.

    • Steel Pickling Line
      Pickling Line

      Pickling in acid tanks removes surface scale or oxide from the hot rolled steel making it suitable for cold rolling.. Monitoring surface condition after pickling can verify the success of this process.

    • Steel Punching Stanze
      Punching Stanze

      Punching is used to create holes in steel sheets, which can create surface defects in the metal. The edges of the holes can be monitored by our edge inspection system.
