Steel Cold
Cold rolling is often used for thinner steel products, which must be cold-rolled to their final thickness. It provides a smoother surface finish than hot rolling.

More energy is required to roll cold metal than that softened by heating, so an efficient process reduces production costs. Cold mills can operate at roll speeds up to 7,000ft per minute, making automated inspection essential.

Cold-rolled steel is subject to several applications 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 steel production processes, maintaining line speeds and rapidly detecting defects. Automation options provide reliable inspection even at fast roll speeds.

  • Applications +

    • Steel Annealing

      Prior to cold treatment, the metal can be annealed to soften it and improve machinability. This process can also repair surface defects – the success of this can be monitored by a reliable inspection system.
