Continuous strip treatment line for pickling and passivation
Pickling and passivating
After the annealing process the strip is pickled to remove any remaining oxide deposits from its surface. Depending on customer preferences, OTTO JUNKER offers both flush and spray pickling systems, both of which can be further customized to suit the application. The downstream finish-brushing machines create the customer-specific surface finish, using brushes with a fill material adapted to the given product. In order to avoid premature re-oxidation of the bare metal, the strip is passivated and dried in a spray chamber before it is wound into coils again.
