The low carbon wire galvanizing process is usually accompanied by in-line process annealing. This continuous furnace heat treatment lowers the stresses introduced during wire drawing and increases the ductility of the continuous galvanizing line. The oxidized wire surface (scale) resulting from annealing is removed by cleaning in acid (pickling) followed by rinsing and fluxing. The wires are submerged in liquid zinc for the hot-dip galvanizing process. The galvanized surface provides a sacrificially protective coating against corrosion to the steel wire base. Commercial (minimum) coating and heavy zinc coatings can be applied on the same process line with our modular nitrogen and vertical pad wiping systems.
With production ranging from 1 to 8 tons per hour and wire speeds ranging from DV=100 to over DV=250, QED has the experience and know-how in low carbon galvanizing. We combine state-of-the-art components with innovative designs and years of experience to give our customers the most reliable continuous galvanizing line equipment.
