This invention relates to the field of online pickling technology, and discloses an online pickling spray device and method for steel wire. The device includes an acid tank, a pickling cylinder disposed within the acid tank, multiple spray components arranged sequentially at intervals along the axial direction of the pickling cylinder, and inlet guide wheels and outlet guide wheels respectively disposed on both sides of the upper surface of the acid tank. The steel wire passes sequentially through the inlet guide wheel, the pickling cylinder, and the outlet guide wheel. Each spray component includes multiple nozzles evenly distributed circumferentially along the pickling cylinder. Along the direction of steel wire travel, the angle between the axis of each nozzle and the direction of steel wire travel gradually decreases from 90°. In this invention, the gradually changing angle arrangement causes the acid to scour the surface of the steel wire along the travel path. The inlet section mainly uses normal impact to break scale, while the outlet section mainly uses tangential scouring and peeling, achieving a synergistic effect of impact scaling and shear peeling. Simultaneously, the evenly distributed circumferential nozzles effectively reduce local pickling dead zones, improving pickling efficiency and uniformity.
