In ArcelorMittal Vega, the coils pass first through the Pickling line, which is a continuous process. The ends of the sheets are joined by laser soldering, and then the iron oxides, which have formed during the hot roll process, are removed.
In this removal process, the sheets pass through two processes: mechanical (in machines) and chemical, through a turbulent bath of an acid solution that removes the oxide. After being used, this acid passes through a regeneration process and is reused. The iron particles removed in this process are supplied to companies that use them as raw material.
