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.
