Pickling of forgings uses chemical reactions to remove metal oxides.

For small and medium-sized forgings, they are usually loaded into baskets in batches and go through processes such as degreasing, pickling corrosion, rinsing, and drying.

The forging pickling method has the characteristics of high production efficiency, good cleaning effect, no deformation of forgings, and no restrictions on shape.

Chemical reactions during forging pickling will inevitably produce harmful gases, so the pickling room should be equipped with an exhaust device.

When pickling different metal forgings, different acids and component ratios should be selected according to the properties of the metal, and the corresponding pickling process (temperature, time and cleaning method) system should be adopted.
