Description

띠 형상 건식 신선용 윤활재 및 그 제조방법{BAND-SHAPED LUBRICATING MATERIAL FOR DRY WIREDRAWING AND PROCESS FOR PRODUCING SAME}Band-shaped dry wire lubricant and its manufacturing method {BAND-SHAPED LUBRICATING MATERIAL FOR DRY WIREDRAWING AND PROCESS FOR PRODUCING SAME}

본 발명은, 선재나 로드(rod)와 같은 모재를 인발하여(즉, 뽑아내어) 직경을 축소시켜서 신선(wiredrawing)할 때, 그 모재와 다이스와의 직접 접촉에 의한 타서 눌러붙는 것을 방지하여, 안정적인 가공 상태를 유지하기 위하여 이용되는 띠 형상 건식 신선용 윤활재에 관한 것이다.The present invention, when drawing a base material such as a wire rod or a rod (that is, pulled out) to reduce the diameter and wire drawing, to prevent the pressing by the direct contact between the base material and the die, The present invention relates to a belt-shaped dry drawing lubricant used to maintain a stable processing state.

철강이나 비철금속 등의 금속제의 두꺼운 직경의 선재나 로드와 같은 모재를, 다이스와 같은 형강(型鋼)의 구멍으로부터 인발하여, 가는 직경의 선재나 로드 등으로 직경 축소시켜서 소성변형시키는 신선 가공 시, 분립(粉粒)의 건식 신선용 윤활제가 범용되고 있다. 이 건식 신선용 윤활제는, 모재와 다이스가 직접 접촉해서 타서 눌러붙는 것을 방지하고, 쉽게 미끄러져서, 안정한 가공 상태로 유지되므로, 이용할 수 있는 것이다.In the case of wire drawing, in which a thick diameter wire rod made of metal such as steel or nonferrous metal or a base material such as rod is drawn from a hole of a section steel such as a die and reduced in diameter with a thin diameter wire rod or rod, The dry drawing lubricant of (i) is widely used. This dry drawing lubricant can be used because the base material and the die are in direct contact with each other to prevent burning and pressing, and are easily slipped and maintained in a stable processing state.

예를 들면, 특허문헌 1에 포화 지방산의 금속염과, 붕소 비함유의 수용성 무기 축합화합물 및/또는 그 축합전구 화합물이 함유되어 있는 붕산염 비함유의 건식 신선용 윤활제가 개시되어 있다. 이러한 포화 지방산의 금속염, 무기물 및 첨가제로 구성되어 있는 건식 신선용 윤활제는, 분말 형태 또는 과립 형태의 형상을 취하고 있다. 이 분말 형태 또는 과립 형태의 건식 신선용 윤활제는, 고온·고압·고속과 같은 가혹한 신선가공 조건 하에 사용할 수 있고, 또한 가는 직경에서부터 두꺼운 직경까지의 선 직경으로의 직경 축소나, 저속으로부터 고속까지의 선속에도 대응할 수 있으므로, 폭넓게 이용되고 있다.For example, Patent Literature 1 discloses a borate-free dry drawing lubricant containing a metal salt of a saturated fatty acid, a water-soluble inorganic condensation compound containing no boron, and / or a condensation precursor compound thereof. Lubricating agents for dry drawing composed of metal salts, inorganic substances and additives of such saturated fatty acids take the form of powder or granules. This powder or granular dry drawing lubricant can be used under severe drawing conditions such as high temperature, high pressure, and high speed, and can also be used to reduce diameters from thin diameters to thicker diameters, or from low speeds to high speeds. As it can cope with ship speed, it is widely used.

분말 형태 또는 과립 형태의 건식 신선용 윤활제는, 도 4에 나타낸 바와 같이, 신선가공 시, 다이스 박스(3) 속에 다량으로 투입되어, 그 일부가 선재(2)와 함께 다이스(4)에 유입됨으로써, 선재(2)에 윤활피막(6)을 형성하여, 선재(2)와 다이스(4)의 직접 접촉을 방지한다. 다이스 박스(3)에 투입된 건식 신선용 윤활제(10)는, 그 대강 2할 정도가 선재(2)와 함께 다이스(4)에 유입되어 소비되지만, 나머지는, 가공 열에 의해 건식 신선용 윤활제(10)가 일부 분해되어 탄화물이 되어버리기 때문에, 윤활능력이 저하되거나, 선재(2) 또는 다이스(4) 등의 마모분이 혼재되거나 하므로, 신선의 품질을 확보하기 위하여, 사용할 수 없게 된다. 그 때문에, 나머지 전량을 부득이 파기하고 있다.As shown in FIG. 4, the dry drawing lubricant in powder form or granule form is introduced into the die box 3 in a large amount during drawing, and a part thereof flows into the die 4 together with the wire 2. The lubricating film 6 is formed in the wire rod 2 to prevent direct contact between the wire rod 2 and the die 4. The rough drawing lubricant 10 put into the die box 3 is consumed by roughly 20% flowing into the die 4 together with the wire rod 2, but the remainder is a dry drawing lubricant 10 by the heat of processing. ) Partly decomposes and becomes a carbide, so that the lubricating ability is lowered, or wear powder such as wire rod 2 or die 4 is mixed, so that it cannot be used to secure the quality of the drawing. For this reason, the remaining amount is inevitably destroyed.

최근의 사회 정세는, 자원의 재활용 등 지구 환경을 고려하는 사회로 이행하고 있으므로, 이러한 대량 소비·대량 파기는 문제시 되고 있다. 또, 분말 형태 또는 과립 형태이기 때문에, 사용 시에 있어서의 분진 등에 의한 작업 환경의 악화, 작업자의 건강 피해, 환경 오염 등을 야기한다고 하는 문제가 생기고 있다. 또한, 가공 형상에 따라서 건식 신선용 윤활제의 입자 형상의 적절한 사용이나 조정이 필요해서, 작업자 측 및 생산자 측에 있어서 비효율적이었다. 이러한 문제점으로부터 가공성 및 생산성을 유지하면서, 작업 환경의 개선을 도모하는 동시에, 지구 환경을 배려해서, 분말형상이 아닌 혁신적인 건식 신선용 윤활재가 요구되고 있었다.The recent social situation is shifting to a society that considers the global environment, such as recycling of resources, and therefore, such a large consumption and mass destruction is a problem. Moreover, since it is powder form or a granule form, the problem of causing deterioration of the work environment by dust at the time of use, a worker's health damage, environmental pollution, etc. has arisen. Moreover, according to the process shape, appropriate use and adjustment of the particle shape of the dry drawing lubricant were necessary, and it was inefficient on the worker side and producer side. From these problems, while improving workability and productivity while maintaining workability and productivity, in consideration of the global environment, innovative dry drawing lubricants, rather than powder form, have been required.

(신선가공의 성능평가)(Performance Evaluation of Fresh Processing)

선재의 윤활제로서, 실시예 1의 띠 형상 건식 신선용 윤활재, 비교예 1의 칼슘계 건식 신선용 윤활제 및 비교예 2의 띠 형상 폴리에틸렌을 각각 이용해서, 신선기에 의해 신선가공했을 때에 있어서의 성능평가를 행하였다.As the lubricant of the wire rod, the performance evaluation when the wire was processed by a drawing machine using the band-shaped dry drawing lubricant of Example 1, the calcium-based dry drawing lubricant of Comparative Example 1 and the band-shaped polyethylene of Comparative Example 2, respectively Was performed.

모재인 선재(탄소강 72A 재료)를, 12중량% 염산 수용액에 의해, 피가공 선재표면의 산화 스케일(scale)을 산세(酸洗) 제거한 후, 수세를 수회 실시하고, 산처리의 중화 및 방청을 위하여, 80℃ 정도로 데워진 1중량% 보락스 수용액 중에 침지 하였다. 피가공 선재를 보락스 수용액으로부터 끌어 올려서 건조시킴으로써 피가공 선재 위에 보락스 피막을 형성시켜, 전처리 가공을 행하였다. 계속해서 다이스 박스 내에 실시예 1에서 얻어진 띠 형상 건식 신선용 윤활재를 1g 투입하고, 선속: 40m/분, 선 직경의 직경 축소: 2.8㎜φ→ 2.5㎜φ→ 2.25㎜φ→ 2.00㎜φ의 3단계, 신선량: 2㎏의 조건에 따라서, 전처리를 실시한 피가공 선재의 신선을 행하였다. 3단계의 신선가공에 있어서, 1패스에만 윤활재를 사용하고, 2,3패스에서는 윤활재를 사용하지 않았다.The base material wire (carbon steel 72A material) was rinsed off with a 12 wt% aqueous hydrochloric acid solution to remove the oxidation scale on the surface of the wire to be processed, and then washed with water several times to neutralize and prevent acid treatment. In order to immerse in a 1% by weight aqueous solution of Borax warmed to about 80 ℃. The borax film was formed on the to-be-processed wire rod by pulling up the to-be-processed wire rod from the borax aqueous solution, and drying was performed, and the pretreatment process was performed. Subsequently, 1 g of the strip-shaped dry drawing lubricant obtained in Example 1 was introduced into the die box, and the line speed: 40 m / min, the diameter reduction of the wire diameter: 2.8 mm phi 2.5 mm phi 2.25 mm phi 2.00 mm phi 3 Step and drawing amount: Drawing was carried out of the pretreated wire rod under the conditions of 2 kg. In the three-step fresh processing, the lubricant was used only in one pass, and no lubricant was used in the second and third passes.

마찬가지로, 윤활재 대신에 비교예 1의 칼슘계 건식 신선용 윤활제를 300g, 비교예 2의 띠 형상 폴리에틸렌을 1g 사용해서 각각 피가공 선재의 신선을 행하였다.Similarly, 300 g of the calcium-based dry drawing lubricant of Comparative Example 1 and 1 g of the band-shaped polyethylene of Comparative Example 2 were used instead of the lubricant to wire the wire to be processed.

각 윤활제를 이용해서 신선가공한 선재의 표면을 육안으로 관찰한 결과를 표 1에 나타낸다.Table 1 shows the results of visually observing the surface of the wire rod processed by each lubricant.

Figure pct00001
Figure pct00001

표 1로부터 명확한 바와 같이, 어느 쪽의 선 직경에 있어서도, 실시예 1의 띠 형상 건식 신선용 윤활재는 신선 후의 선재 표면에 띠 형상 건식 신선용 윤활재가 균일한 필름 형태로 전착하고 있었던 것에 대해서, 비교예 1의 종래품인 분말 형태의 칼슘계 건식 신선용 윤활제는 2패스째 이후, 건식 신선용 윤활제의 막 끊김에 의해 일부 금속 광택이 생겼다. 또한, 비교예 2의 열가소성 수지 단독인 띠 형상 폴리에틸렌은 1패스째부터 선재에 균일하게 윤활피막이 형성되지 않아 금속광택이 생겼다. 2패스째는 중지하였다.As is apparent from Table 1, in either of the wire diameters, the band-shaped dry drawing lubricant of Example 1 was electrodeposited in the form of a film in which the band-shaped dry drawing lubricant was deposited on the wire rod surface after the drawing. The powdered calcium-based dry drawing lubricant of Example 1, after the second pass, caused some metallic luster due to film breakage of the dry drawing lubricant. Moreover, since the strip | belt-shaped polyethylene which is the thermoplastic resin single of the comparative example 2 did not form a lubricating film uniformly in a wire rod from the 1st pass, metal gloss was produced. The second pass was stopped.

신선가공한 선재를 신선선재용 세정제(쿄에이샤카가쿠(共榮社化學) 주식회사 제품; 라이트크린 A-1)로 세정해서 세정 전후의 중량차로부터 각 윤활제의 부착량을 산출하고, 세정후 선재의 표면을 레이저 현미경으로 400배로 확대해서 관찰하였다. 그 결과를 표 2에 나타낸다.The freshly processed wire rod is cleaned with a fresh wire cleaner (made by Kyoeisha Kagaku Co., Ltd .; Light Clean A-1), and the amount of adhesion of each lubricant is calculated from the difference in weight before and after washing. The surface was magnified and observed by 400 times with a laser microscope. The results are shown in Table 2.

Figure pct00002
Figure pct00002

표 2로부터 명확한 바와 같이, 실시예 1의 띠 형상 건식 신선용 윤활재를 이용한 경우에는, 어느 쪽의 선 직경에 있어서도, 띠 형상 건식 신선용 윤활재의 부착량이 많은 경향이 있고, 다이스와 선재의 직접 접촉에 의해서 생기는 평탄한 부분의 면적 비율(평탄율)이 비교예에 비해서 낮은 경향인 것을 알 수 있다. 즉, 신선 상태가 양호한 것으로 확인되었다. 그에 대해서, 비교예 1은 2패스째 이후부터 평탄율이 실시예 1보다도 큰 경향이 인정되는 3패스째 신선 후에는 일부 타서 눌러붙음이 확인된다. 즉, 3패스째 이후에는 신선 상태가 불량한 것을 알 수 있었다. 비교예 2에 이르러서는, 1패스째부터 타서 눌러붙음이 다수 확인되었다. 즉, 신선 상태가 불량한 것을 알 수 있었다.As apparent from Table 2, in the case where the band-shaped dry drawing lubricant of Example 1 was used, there was a tendency that the adhesion amount of the band-shaped dry drawing lubricant was large in any of the wire diameters, and the direct contact between the die and the wire rod was used. It turns out that the area ratio (flat rate) of the flat part which arises by a tendency is low compared with a comparative example. That is, the fresh state was confirmed to be good. On the other hand, in Comparative Example 1, after the third pass, in which the tendency of the flatness is greater than that of Example 1 is recognized from the second pass and after, the part is confirmed to be burnt and pressed. That is, after the third pass, the fresh state was found to be poor. In Comparative Example 2, a large number of burning and pressing were confirmed from the first pass. That is, it was found that the fresh state was poor.

실시예 1의 띠 형상 건식 신선용 윤활재는, 종래의 건식 신선용 윤활제와 열가소성 수지가 상호작용함으로써, 윤활피막성, 전착성이 향상되고, 게다가 띠 형상이므로 효율 좋게 다이스에 유입되어 균일한 윤활피막을 형성할 수 있다. 그 효과에 의해 종래의 건식 신선용 윤활제보다도 적은 사용량으로 효율이 좋은 신선가공을 기대할 수 있고, 또한, 띠 형상이기 때문에 종래의 분립의 건식 신선용 윤활제에 비해서 분진에 의한 작업 환경의 악화 등이 생기기 어렵다고 판단된다.In the band-shaped dry drawing lubricant of Example 1, the conventional dry drawing lubricant and the thermoplastic resin interact with each other to improve the lubricating film property and electrodeposition property, and furthermore, because the strip-shaped lubricant is introduced into the die efficiently and uniformly, the lubricating film Can be formed. Due to this effect, it is possible to expect an efficient drawing process with less usage than a conventional dry drawing lubricant, and because of the strip shape, the deterioration of the working environment due to dust, etc., occurs compared to the conventional dry drawing lubricant of powder. I think it is difficult.

본 발명의 띠 형상 건식 신선용 윤활재는, 철강과 같은 금속제로 두꺼운 직경의 선재, 와이어, 관, 막대, 로드 등의 모재를, 다이스 등의 형강으로부터 인발해서, 직경 축소시킨 선재나 로드 등으로 소성 변형시켜서 직경 축소시키는 신선 가공 시 이용된다.The strip-shaped wire drawing lubricant of the present invention is made of a metal such as steel, and a base material of a thick diameter wire rod, a wire, a pipe, a rod, a rod, and the like is drawn from a shape steel such as a die, and then fired by a wire rod or rod having a reduced diameter. It is used in drawing processing to deform and reduce the diameter.
