Therefore, it is preferable that not only the steel wire W but also the coating solution is preheated to about 60 ° C. to 80 ° C., which is the same temperature as the wire preheating temperature. Since the etching reaction is promoted by increasing the total acidity, it is considered that the coating reaction is also promoted. Therefore, increasing the total acidity is effective as a means for shortening the coating treatment time.

- the coating of the steel wire W with the lubricant makes it possible to cold work while lubricating the steel wire W, and allows the steel wire to be processed smoothly.
- This continuous surface treatment method includes the descaling step P3 as a pretreatment of the coating treatment step P5, and a slurry containing grit-like abrasive particles with respect to the surface of the steel wire W in the descaling step P3. It is characterized by injecting.

- the nozzles are alternately distributed to the left and right along the circumferential direction when viewed along the axis of the steel wire.
- the slurry is injected at an injection pressure of 0.2 MPa or more and 0.6 MPa or less, for example.
- An injection pressure of 0.2 MPa or more enables formation of a new surface as described below.
- the injection pressure of 0.6 MPa or less makes the suppression of processing defects such as cracking of the steel wire rod and die seizure more remarkable than the processing at a higher injection pressure.
- This method is characterized in that the slurry described above contains grit-like abrasive particles.
- This grit-like abrasive particle means a grit prescribed as a metal-based abrasive for blasting in JIS Z 0311, and has an angular shape with a ridge angle before use, and has a round surface. It refers to a particle having a proportion of less than 1 ⁇ 2 of the entire surface of the particle. Therefore, the grit-like abrasive particles are shot processing metal-based abrasives defined in JIS Z 0311, that is, “there is no ridge angle, crushing surface or other sharp surface defects in the state before use, and the major axis has a minor axis. “Spherical particles within 2 times” are greatly different in shape.
- the “new surface” refers to a surface on which the scale and the surface layer of the old metal wire W are scraped by spraying the slurry, and a new portion of the metal wire W on the lower side appears.
- the type of metal constituting the grit-like abrasive particles is not limited. From the viewpoint of processing efficiency of descaling, it is preferable that the metal is selected so as to constitute particles having a hardness higher than the hardness of the steel wire to be processed. Specifically, for the grit-like abrasive particles, steel or stainless steel having excellent toughness is preferably used from the viewpoint of preventing sticking residue on the surface of the steel wire.
- preheating For example, if the temperature at which the steel wire is heated in preheating is less than 60 ° C., the effect of preheating is reduced and the formation of the phosphate coating becomes insufficient. On the other hand, preheating at a temperature exceeding 80 ° C. excessively increases the temperature of the phosphate coating solution, causing hydrolysis or altering the coating treatment solution. On the contrary, it is not preferable from the aspect.

- a descaling step of generating a new surface on the surface of the steel wire by injecting a slurry containing grit-like abrasive particles onto the surface of the steel wire before the formation of.
- the use of the grit-like abrasive particles promotes a chemical conversion reaction in the subsequent phosphate coating process by generating a new surface on the surface of the steel wire by fine surface cutting by the corners of the grit-like abrasive particles. This makes it possible to obtain a phosphate coating in a short time.
- the formation of the phosphate coating is promoted by performing wet blasting while keeping the spray pressure of the slurry within an appropriate range, for example, the range of 0.2 MPa to 0.6 MPa. Accordingly, the work-affected layer generated on the surface of the steel wire, the work hardening amount on the surface of the steel wire, the work hardening depth, and the like can be reduced.
- the temperature of the steel wire rod is adjusted to a phosphate coating liquid by the preheating step.
- the temperature can be close to, for example, a temperature of 60 ° C. or higher and 80 ° C. or lower, thereby promoting the chemical conversion reaction when forming the phosphate coating. Therefore, it becomes possible to form a phosphate coating on the steel wire in a shorter time with high productivity.

- the present inventors confirmed that the steel wire after the treatment has sufficient performance when neither the “drawing result” nor the “forging result” has x, and this is a preferred embodiment. However, a case where only one of them is not x is treated as an embodiment corresponding to this.
- the coating amount of Experimental Examples 1 to 3 using spherical abrasive particles for descaling is 2.7 g / m 2 to 3.2 g / m 2 .
- examples 4 and 5 were used grit shaped abrasive particles, coating adhesion amount 5.0 g / m 2, has a 5.2 g / m 2, the amount of coating deposition is increased significantly I understand that. From this, it can be seen that productivity can be significantly improved by using grit-like abrasive grains (abrasive particles) for descaling.
