ABSTRACT:
This invention concerns a novel pickling apparatus for removing oxides from the surface of a plurality of parallel laterally spaced wires, continuously moving axially through an enclosed pickling area. The pickling area encompasses one or more sections of turbulent hot acid (hydrochloric or other) pickling liquor submerging the wires. Each section essentially comprises a flooded turbulent processing tray, corrosion resistant centrifugal re-circulating pump, lower reservoir tank and wire wiping components. The pickling fluid is pumped from the lower reservoir tank into the processing tray through laterally (with respect to wire direction) mounted headers. Each header has a plurality of holes to discharge the fluid into the process tray in highly turbulent manner. Weirs at each end of the tray support the wires and flood the tray. The acid sections can be operated at different acid concentration levels by introducing fresh acid to the final section and cascading the overflow to the other sections in a direction opposite to that of the wire. Alternatively, all sections can be operated at the same concentration by connecting piping. The pickling area is enclosed at each end by water curtains, and on the top, bottom and sides by solid corrosion resistant walls. The wire entry end has a singe or double water curtain fed through a corrosion resistant pump from a reservoir tank. The wire exit end has two or three rinse sections to remove the acid from the wires. Each rinse section also incorporates a water curtain to seal in acid fumes.
