Pickling-free Electrolytic Phosphating Production Line

The environmental protection equipment non-pickling electrolytic phosphating production line developed by our company in recent years is suitable for the drawing high, medium and low-carbon ferrous metal wires with a diameter range of 5.5-30mm. Phosphating dispenses with the pickling process, and because it does not require pickling for its special contribution to environmental protection, it is an ideal equipment recognized by local environmental protection departments and pursued by users in the steel wire industry and fastener industry.
The production process: pay-off-peeling-steel brushing machine or belt sander-electrolytic phosphating tank-wire drawing and take-up.
