Technical background of the invention and its problems The secondary processing of wire rods for cold forging involves descaling the wire rods, applying lubrication treatment, primary wire drawing, and then spheroidizing the wire rods to cope with work hardening caused by wire drawing. A common method is to perform secondary wire drawing (finish wire drawing) using a skin bath after annealing, second-stage descaling, and lubrication treatment.

On the other hand, in response to increasingly strict quality assurance requirements in recent years, flaw detection and flaw cleaning of drawn wire materials are extremely important processes. However, in general, online flaw detection and flaw cleaning of wire rods is extremely difficult.When flaw care is performed, the lubricant on the surface of the wire rod is scraped off, which can lead to the occurrence of briquettes during cold forming in the subsequent process. Therefore, surface flaw detection was performed using conventional skin bath wire drawing17, and the flaw detection area was marked.
Marked parts are rejected during cold forging (when flaws are partially cleaned using a grinder, etc. on the off-fin after being partially wound, or when flaws occur on the top or tail of the coil and are cut off) ). but,
Since this method is inefficient and has a poor yield, recently a partial valence method has been reported for surface flaw detection and care, in which only surface flaws are cut and removed, with the aim of improving yield and efficiency. This method uses an automatic care machine that grinds away the flaws based on the surface flaw information from the flaw detector, which has a higher yield compared to previous manual methods, and is efficient because the care is done automatically. It is. Regarding this partial valence method, the present inventors have also proposed a dry continuous wire drawing method for wire rods using the method (Japanese Patent Application No. 168997/1982).
7-221610). However, in the case of the continuous wire drawing method mentioned above, although it has the excellent characteristics of achieving high efficiency and high yield, it does not have a lubrication treatment process for cleaning scratches, so it does not require cold treatment after winding. I had to relubricate the bond to prevent it from seizing.

As described above, in conventional skin pass wire drawing, in order to avoid seizure during cold forging, wire rod flaws are not removed using on-fins. Even if the method fails, there is no lubrication process for the scratch cleaning marks, so it was necessary to lubricate the scratch cleaning marks with an off-fin.

No. 8-168997) can be used. This flaw cleaning machine 1 uses the inner surface of a rotating cylindrical grindstone 1-.
This uses an internal grindstone grinding method that allows selective removal of specific areas where surface flaws exist by pressing the grindstone against a specific circumference of the running wire with a constant load. be. According to this method, only a specific circumferential portion of the wire rod can be selectively treated, so the yield is extremely high, and the maintenance f1. Since the marks are smooth red, there is little variation in the dimensions and shape of the wire after cleaning, so cleaning +1.
It has the advantage of having little effect on the next process of vinegar.

In this invention, after the scratch treatment described in E, the scratches are preheated, treated with zinc phosphate, washed with water, lubricated, and dried immediately. That's true. Wire rods for cold forging use the lubricant during wire drawing as a lubricant during wire drawing. Process. Preheating in this lubricating base treatment is carried out in the shortest possible time to achieve the specified zinc phosphate deposit (
This is done to give a target coating amount of 5f/rlLJ, J-), and as a preheating method, for example, steam spraying may be used. Furthermore, an alternative to the method of adhering zinc phosphate is to use a method of spray coating a zinc phosphate solution. Figure 1 shows the relationship between the reaction time and the amount of zinc phosphate deposited when the wire is preheated using the steam blowing method and the zinc phosphate solution is applied using the spray coating method, in comparison with the case of preheating I7. This is a diagram. It can be seen from each chart that in the zinc phosphate treatment, preheating the wire allows a predetermined amount of zinc phosphate to be deposited in a shorter time.

The lubrication treatment performed after the zinc phosphate treatment is performed by using a non-reactive lubricant (stearin, calcium, etc.). In this case, since it is a physical adhesion and no reaction time is required, wet or dry spray methods can be considered as the application method, but as shown in Figure 2 and Table A, the amount of lubricant adhered Application by a wet spray method is preferred due to the adhesion of the coating. In addition, Figure 2 is a chart showing the relationship between the treatment concentration and the amount of adhesion of non-reactive lubricant using the wet spray method. This is a comparison. As a drying method, for example, infrared drying/lung (maximum temperature 800C) can be used.
