Abstract

The invention discloses a surface treatment method for a steel wire rod. The surface treatment method comprises the following steps: releasing a wire; mechanically shelling; blowing; performing hot washing; performing acid washing; washing; performing surface coating; drying; drawing; collecting, wherein the acid washing solution is mixed solution of hydrochloric acid and sulfuric acid, and the volume ratio of the two acid solutions is 1:1; the operation mode of the steel wire rod is a linear advancing mode. The surface treatment method has the advantages of less amount of acid and good cleaning effect, the production cost can be effectively reduced, and the surface treatment method is an energy-saving and environment-friendly production method.

Description

technical field [0001] The invention relates to the technical field of surface treatment of metal products, in particular to a surface treatment method for wire rods. Background technique [0002] In the production process of metal products, due to the existence of scale on the surface of wire rods, the subsequent drawing of steel wires is affected, so removing scale is an essential and important process in the production of metal products. Pickling tanks are often used for surface treatment of raw material wire rods for steel wire rope and other products, which consumes a lot of energy, and the production sites of most enterprises are not clean enough, causing pollution; some enterprises have switched to closed tunnel-type hydrochloric acid pickling production lines; steel cord , bead steel wire, high-pressure hose steel wire, cutting steel wire and other high-end metal products usually use simple mechanical shelling + electrolytic pickling production line. Although it is b...
