Beschreibung
Zusammenfassung:	A method to form a phosphate coating on a steel wire, the method including: continuously forming a phosphate coating on a steel wire before being subjected to cold forming; and a descaling of jetting slurry including grit-like abrasive particles onto the steel wire before forming the phosphate coating, thereby producing a new surface on the steel wire. The method can further include a preheating of the steel wire after the descaling and before the coating treatment. The method makes it possible to form a phosphate coating on a steel wire in a short time with high productivity without causing significant forming deterioration on the surface of the steel wire.
