Pickling Line

Metal surfaces can contain impurities that may affect the future use of the product or impact upon further processing. To remove these impurities, most copper alloys are pickled in dilute sulfuric acid, though a more complex pickle is used for brass.

The pickle line typically follows the hot mill section of metal production. Once the coiled metal leaves the mill, it is unwound and passes through a series of tanks filled with the pickling acid and rinse tanks. It is then sent for further processing in the cold rolling mill if required.

AMETEK Surface Vision’s flexible, easy-to-use surface inspection system has been shown to increase pickling line speeds by 30%, boosting production efficiency. It offers improved quality control and an early detection system for defects, along with seamless process integration and a compact footprint.
