Electrolytic derusting

Steel is derusted and descaled in alkaline baths.

To remove flash rust, the workpiece to be processed is connected as a cathode or as an anode if pickling residues are to be removed. In this way, light rust can be removed within one minute, while the removal of scale or heavier rust can sometimes take up to 15 minutes. The current density is between 10 A/dm² for derusting and 15 A/dm² for descaling.
