The surface treatment technology of wire rod used in prestressed concrete is the surface treatment of metal wire. The Wire rod in the continuous movement State completes the following steps: first by mechanical stripping, straightening and high-pressure water rinse, and then sulfuric acid electrolysis pickling, and then through high-pressure water rinse, rinse water, hot water rinse after phosphating coating, and then hot water rinse, and then boron into the wire drawing machine drawing. The effect of removing the tin oxide is good, the pickling process is simplified, the quality of phosphating coating is stable and the wire quality is improved.Wire Surface Treatment

              The continuous production operation of wire rod from surface treatment to drawing is realized, the production condition is improved and the production efficiency is improved greatly. The basic elimination of environmental pollution, but also extend the service life of equipment, reduce production costs. It is not only suitable for surface treatment of prestressed strand Special-line material, but also for surface treatment of common wire.Wire Surface Treatment

              1. The surface treatment process of prestressed wire rod, including pickling and phosphating coating, is characterized in that: The Wire (1) completes the following steps in a continuous motion state: first through the discharge line, mechanical stripping, straightening and high-pressure water rinse, and then sulfuric acid electrolysis pickling, and then through high-pressure water rinse, rinse water, hot water rinse after phosphating coating, and then hot water rinse, and then boron into the wire drawing machine drawing.Wire Surface Treatment
