FORFARANDE OCH ANORDNING FOR KONTINUERLIG ELEKTROLYTISK RENGORING AV STALTRAD

摘要

Electrolytic descaling of a steel wire is carried out at a high current density by a non-contact flow method in the presence of ferrous ions in the electrolyte to prevent the consumption of electrodes. The wire 1 passes between d.c. coupled pairs of anodic 31 and cathodic electrodes 32 in an electrolytic bath 4 supplied with an electrolyte circulating system 6 for removing sludge and adjusting the Fe<2+> concentration. Current flows through the steel wire without any direct contact with a power source or electrodes.
