うに一連の工程はバツチ処理であるため、処理に
多大な手間と時間を要していた。 Generally, when drawing a wire, descaling is performed prior to lubrication treatment. Conventionally, in the case of stainless steel wire rods, hydrofluoric nitric acid has been used for descaling due to its ability to remove scale. Since this fluoronitric acid is dangerous, it has been a major problem in terms of the working environment. In addition, in a series of processes such as descaling, lubrication base treatment, and lubrication treatment, the batch is wound into a coil and immersed in each treatment tank using a hook conveyor, and after treatment is transferred to the next tank. method was adopted. However, in this method, as shown in FIG.
The mutual contact portions t do not come into contact with each processing liquid (agent), and the zone Z surrounded by each wire L is not sufficiently supplied with new liquid. As a result, the contact area t is not sufficiently descaled and lubricant is not supplied, so a lubricant film is not generated or even if it is formed, it is only a small amount, which tends to have a negative effect on stretchability. Ta. In addition, the contact portion t and the zone Z portion are not sufficiently washed with water after pickling, and there is also the drawback that rust is likely to occur after the lubrication treatment. Moreover, as described above, the series of steps is batch processing, which requires a great deal of effort and time.
一方、特開昭52−63849号（第１先行例）には
伸線に当り、シヨツトブラストし、次いで表面を
研削装置により研削し、その後において樹脂コー
トすることが示されている。 On the other hand, Japanese Patent Application Laid-Open No. 52-63849 (first prior example) discloses that during wire drawing, the wire is shot blasted, then the surface is ground with a grinding device, and then coated with a resin.
また、特開昭53−1640号公報（第２先行例）に
は、ステンレス鋼板の表面をシヨツトブラスト
し、次いで酸洗することを開示している。 Furthermore, Japanese Patent Application Laid-open No. 53-1640 (second prior example) discloses that the surface of a stainless steel plate is shot blasted and then pickled.

潤滑被膜のように、化学的反応に伴う付着を伴う
ものではなく、したがつて、反応時間を必要とし
ない反面、潤滑性が後記実施例のように、良好で
ない。 However, the resin coat film in the first prior example is a physical adhesion, and unlike the lubricant film of the present invention, which will be described in detail later, it does not involve adhesion due to a chemical reaction, and therefore requires reaction time. On the other hand, the lubricity is not good as in the examples described later.
第２先行例では、シヨツトブラスト処理と酸洗

た伸線の潤滑処理前の処理としてシヨツトブラス
トおよび酸洗を行うという思想はない。 In the second prior example, shot blasting and pickling are combined, but the target is a steel plate, and there is no concept of performing shot blasting and pickling as a treatment before lubrication treatment for wire drawing.
本発明はかかるバツチ方式に代つて連続的に処

ことを主たる特徴としている。 The present invention aims to perform continuous processing in place of such a batch method, and its main feature is that shot blasting and pickling are performed to descale the stainless steel wire.

提供することを目的としている。 The present invention provides a continuous processing method for stainless steel wire that can completely descale, achieve uniform lubrication, significantly shorten processing time, and improve the working environment. It is intended to.
この目的達成のために、本発明は、次記を要旨
とするものである。 To achieve this objective, the present invention has the following gist.

A method for continuous processing of stainless steel wire, characterized in that the wire is drawn after sequentially performing the following treatments while running at a speed of ~100 m/min.

First, a stretched stainless steel wire flowing on a line will be shot blasted. 1 is performed and descaling is performed. Next, high pressure water washing 2
After the scale is removed by Shot Blasting 1 alone, it cannot be removed.

クローム層を除去するものである。 The surface layer of the stainless steel wire rod is pickled with diluted hydrochloric acid, etc. to finish descaling. In other words, since the dechromed layer with a low Cr content on the bare surface of the stainless steel wire cannot be removed by shot blasting 1 alone, the dechromed layer is removed by pickling and the rust resistant function inherent to stainless steel is utilized. It removes layers.

Then, it is subjected to wire drawing processing 10.

そのため、通常室温で5vol％〜10vol％の硫酸又
は塩酸の水溶液が望ましい。 Here, for shot blasting, the abrasive material has an appropriate particle size, preferably 0.3 to 0.6 mmφ.
Grids or steel balls are used. If the particle size is large, the surface roughness becomes large, and the subsequent lubrication base treatment is easy in that a sufficient amount of adhesion can be obtained, but the descaling property is poor. The projection density is
A value of 3000 Kg/m 2 or more is preferable, and if it is less than that, descaling will not be sufficient due to the hardness of stainless steel materials, unlike ordinary steel materials. If only this shot blasting is performed, the dechromized layer will be exposed to the surface and rust will occur.
Therefore, after high-pressure water washing, pickling is performed as described above. The acid for this pickling may be hydrochloric acid or sulfuric acid, but hydrochloric acid is suitable from the viewpoint of working environment, ease of handling, mist generation, dissolving ability, etc. Also, considering the purpose of pickling, a light treatment is sufficient.
Therefore, an aqueous solution of sulfuric acid or hydrochloric acid of 5 vol% to 10 vol% at room temperature is usually desirable.
ところで、ステンレス線材は、塩酸または硫酸

後述する実験例で明らかにするように、シヨツト
ブラストと酸洗とが相互に有機的に組合わされて
始めて良好な結果が得られるものである。 Incidentally, stainless steel wire cannot be descaled with hydrochloric acid or sulfuric acid, and conventionally, it has been necessary to rely on fluoronitric acid. On the contrary,
In the method of the present invention, descaling is mainly carried out by shot blasting, which is a mechanical treatment method, and pickling is then carried out as a supplementary means. As will be made clear in the experimental examples described below, good results can only be obtained when shot blasting and pickling are organically combined with each other.

従来法より濃くする必要があり、少くとも20ｇ／
m2の付着量を確保する必要がある。 After pickling and rinsing with water, lubrication begins. This process may use the same type of liquid as the conventional batch process. As a surface treatment agent, oxalate (for example, product name "Felbond") etc. can be used, but since the method of the present invention uses online processing and the processing time is shorter (10 to 15 seconds), the concentration is lower than that of the conventional method. Must be thicker, at least 20g/
It is necessary to ensure a coating amount of m 2 .

少くとも10ｇ／m2程度の付着量を得るようにする
必要がある。 The subsequent neutralization after washing with water may be the same as in the conventional method, and the subsequent lubrication treatment may be performed using ordinary metal soap (for example, trade name "Bonderijube"). In this case, the concentration of lubricant should be high because the processing time is short (10 to 15 seconds) and online processing is required.
It is necessary to obtain a coating weight of at least about 10 g/m 2 .
乾燥処理には、処理時間が（２〜３秒）と短い
ことに対応して、急速乾燥のため赤外線ヒータま
たは高周波誘導加熱により行うのが最適である。
乾燥後は伸線加工に供せられる。 The drying process is optimally performed using an infrared heater or high-frequency induction heating for rapid drying, since the processing time is short (2 to 3 seconds).
After drying, it is subjected to wire drawing.
ライン速度は任意であるが、伸線加工速度を主
として考えた上で決定すればよい。したがつて、
通常28〜100ｍ／分程度が選ばれる。 Although the line speed is arbitrary, it may be determined based on the wire drawing speed. Therefore,
Usually a speed of about 28 to 100 m/min is selected.
ところで、シヨツトブラストのみでは錆の発生

の結果からも、シヨツトブラストと酸洗との組合
せが必要であることが判明する。 By the way, as mentioned above, shot blasting alone has problems in terms of rust formation. By the way, when we conducted an exposure test to compare the occurrence of rust on Wire A that had been shot blasted and Wire B that had been shot blasted and treated with 5% hydrochloric acid at room temperature, we obtained the results shown in Figure 3. It was done. This result also shows that a combination of shot blasting and pickling is necessary.

かいことが判る。 In addition, in the conventional method, the contact areas between the wire rods and the surrounding zone tend to be insufficiently washed with water after pickling. FIG. 4 shows a comparison result of the surface roughness of a bolt manufactured using a wire rod according to the conventional method and a bolt manufactured using a wire rod processed online according to the present invention. According to the same figure, it can be seen that the bolt surface roughness is finer than that of the conventional method due to less rust generation and less die roughness in the method of the present invention.

According to FIG. 5, it can be seen that according to the present invention, the lubricant is sufficiently adhered even if the area reduction rate is considerably large, and therefore the lubrication performance is excellent.

るから作業環境の向上にもつながる。 As described above, in the present invention, descaling is performed by shot blasting, and pickling is performed as a subsequent treatment, so that descaling and rust prevention can be reliably achieved. Furthermore, since the process is carried out in a continuous manner rather than in batches, the process that conventionally required about 50 to 80 minutes, including wire drawing time, can be shortened to about 20 to 25 minutes. Furthermore, since the entire surface is always treated through continuous processing, it is possible to prevent the conventional situation where the treatment liquid (or agent) does not stick or has uneven adhesion due to the wire being bundled, and it is possible to completely descale. This can prevent rusting as much as possible, and the lubricating film is evenly formed on the wire, improving quality.
It is possible to improve the life of the mold during tertiary processing (bolt processing, etc.) and the life of the wire drawing die. Furthermore, since it is a continuous process, handling flaws in the material can be prevented. Furthermore, the use of fluoronitric acid, which is normally difficult to handle, can be avoided, leading to an improvement in the working environment.
