Pickling

Pickling is the process of treating steel with acid to remove scale and rust from the surface. Both of the conditions are harmful for subsequent forming or metal working operations. Scale because of its hardness can lead to reduction in die life, can increase slitter knives wear and affects rollability within gage tolerances. It may also increase the chances of decarburization in annealing operations. Rusty steel leads to a poor appearance in the final product not to mention the dirt accumulation in the equipment in contact with the steel.

In the past pickling was done in batches. The steel was loaded in acid baths and then had to be loaded in other sections for rinsing and drying. With the high volume and tonnage requirements nowadays, continuous picklers where the entire operations with multiple acid tanks, rinsers, dryers and oilers are installed in series that can pickle around 60 tons/hour are common. Inspection in the pickle line are limited to gage, width and surface quality. Additional inspections may incur extra costs.
