Long product pickling

Long product pickling lines from Fives feature state-of-the-art technology and autonomous control for the most effective surface treatment of  wires, bars and tubes. Using either an HCl (hydrochloric acid) or H2SO4 (sulfuric acid) solution to remove oxides from long products, these totally enclosed systems feature a monorail or overpassing design and coil drying. They are fully automated for maximum throughput, with a process step tracking system and process repeatability.

The chemical management system allows the process to adapt to each coil based on weight, material composition, surface area and treatment steps. It is the best design for the environment and offers the maximum protection for the operator.
