Description

철근 침적장치{steel reinforcement deposition apparatus} Reinforcement deposition apparatus {steel reinforcement deposition apparatus}

본 발명은 철근 침적장치에 관한 것으로, 특히 철근의 표면에 내부식 피막을 형성하기 위해 철근을 내부식성 용액 속에 침적시킬 수 있도록 된 철근 침적장치에 관한 것이다.The present invention relates to a reinforcing bar deposition apparatus, and more particularly to a reinforcing bar deposition apparatus that is able to deposit the reinforcing bar in the corrosion-resistant solution to form a corrosion-resistant coating on the surface of the rebar.

철근은 제강공정에서 제조된 빌렛을 오스테나이트 영역까지 재가열한 후 원하는 크기 및 모양으로 열간 압연하여 제조한다.Reinforcing bars are manufactured by reheating the billets produced in the steelmaking process to the austenite region and then hot rolling them to a desired size and shape.

또한, 열간 압연 후에 템프코어 공정을 실시하여 수냉처리함으로써 저원가로 우수한 기계적 성질을 갖춘 철근을 생산하고 있다.In addition, by performing a temp core process after hot rolling and water-cooling, steel bars having excellent mechanical properties at low cost are produced.

그러나, 상기 수냉처리에 의하여 표면 결함이 많고, 스케일층의 두께가 얇아 부식이 쉽게 발생하는 단점이 있다.However, there are many surface defects due to the water cooling treatment, and the thickness of the scale layer is thin, so that corrosion easily occurs.

따라서, 내부식성 용액으로 표면처리 하여 내부식 피막을 형성함으로써 부식을 방지함으로써 철근의 품질을 향상시키고 수요처의 불만을 해소하였다.Therefore, by surface treatment with a corrosion resistant solution to form a corrosion resistant film to prevent corrosion to improve the quality of the reinforcing bar and resolve the complaints of the customer.

상기 내부식 피막의 일예로서, 실리카 용액을 철근 표면에 분사 도포하여 Si비정질막을 형성시키는 것을 들 수 있는데, 상기와 같은 내부식 피막은 외부 부식 인자의 영향을 차단하는 보호막으로 작용하게 된다.One example of the corrosion resistant coating is spray coating a silica solution onto the surface of the reinforcing bar to form an Si amorphous film. The corrosion resistant coating serves as a protective film to block the influence of external corrosion factors.

그런데, 상기와 같이 내부식성 용액을 철근에 분사하여 도포하면 철근 표면 전체에 고르게 도포하기가 어렵고, 용액을 필요 두께로 도포하는데 시간이 오래 걸리며, 용액 분사에 의해 작업 공간이 오염될 뿐만 아니라 분사 후 철근 표면에 도포되지 않은 분량의 회수가 곤란하여 내부식성 용액의 낭비가 초래되는 문제점이 있었다.However, when spraying the corrosion-resistant solution to the reinforcing bar as described above, it is difficult to apply evenly over the entire surface of the reinforcing bar, it takes a long time to apply the solution to the required thickness, not only contaminated work space by spraying the solution, but also after spraying There was a problem in that the recovery of the amount not applied to the surface of the rebar is difficult to cause the waste of the corrosion-resistant solution.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 내부식성 용액을 철근의 전체 표면에 고르게 도포할 수 있고, 보다 신속하게 도포할 수 있으며, 작업 공간의 오염이 방지되고, 내부식성 용액의 회수율이 향상되어 용액의 낭비를 방지할 수 있도록 된 철근 침적장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the corrosion resistant solution can be evenly applied to the entire surface of the reinforcing bar, can be applied more quickly, the contamination of the work space is prevented, the corrosion resistant solution It is an object of the present invention to provide a reinforcing bar deposition apparatus that can improve the recovery rate of the solution to prevent waste of the solution.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 철근 침적장치의 정단면도이고, 도 2는 도 1의 측단면도이다.1 is a front cross-sectional view of the reinforcing bar deposition apparatus according to the invention, Figure 2 is a side cross-sectional view of FIG.

철근은 열간압연 및 템프코어 공정이 끝나고, 수요처의 요구 길이로 절단된 뒤, 번들링머신(bundling)에서 일정 개수로 묶여진 후, 적재되어 출고를 대기한다.Reinforcing bars are finished after hot rolling and tempering, cut to the required length of the customer, bundled in a certain number in a bundling machine, and then loaded and waited for shipment.

본 발명의 침적장치는 철근의 잠열을 이용하여 내부식 피막이 원활히 형성되도록 하기 위하여 철근온도가 200~250℃가 되는 상기 절단공정과 번들링공정 사이에 설치된다.The deposition apparatus of the present invention is installed between the cutting process and the bundling process in which the rebar temperature is 200 to 250 ° C. so that the corrosion resistant coating is smoothly formed by using the latent heat of the rebar.

도시된 바와 같이, 본 발명은 철근(1)을 지지 및 이송하는 롤러테이블(10)과, 상기 롤러테이블(10)의 하부에 승강 가능하게 설치되고 내부식성 용액이 담겨진 침적조(20)와, 상기 침적조(20)를 승강시키는 유압실린더(30)를 포함한다.As shown, the present invention is a roller table 10 for supporting and transporting the reinforcing bar 1, the sedimentation tank 20 is installed in the lower portion of the roller table 10 and is contained in a corrosion-resistant solution, It includes a hydraulic cylinder 30 for elevating the deposition tank (20).

상기 롤러테이블(10)은 철근(1)을 직접 지지하여 이송하는 다수의 롤러(11)와, 상기 롤러(11)가 회전가능하게 설치된 프레임(12)과, 상기 프레임(12)을 바닥으로부터 소정 높이에 지지하는 서포터(13)를 포함한다.The roller table 10 includes a plurality of rollers 11 for directly supporting and transporting the reinforcing bar 1, a frame 12 on which the rollers 11 are rotatably installed, and the frame 12 from the floor. And a supporter 13 supporting the height.

상기 침적조(20)는 상기 프레임(12)의 하부에 설치되는데, 그 길이와 폭은 상기 프레임(12) 보다 크게 형성되어 승강시 프레임(12)과 간섭이 발생하지 않도록 되어 있다. 철근(1)은 롤러(11)의 설치범위보다 길게 절단되지 않으므로 프레임(12)의 간섭이 회피되면 철근(1)의 간섭 문제도 발생하지 않는다.The deposition tank 20 is installed below the frame 12, and its length and width are larger than that of the frame 12 so that interference with the frame 12 does not occur during lifting. Since the reinforcing bar 1 is not cut longer than the installation range of the roller 11, if the interference of the frame 12 is avoided, the interference problem of the reinforcing bar 1 does not occur.

상기 침적조(20)는 상부가 개방된 직육면체 형상의 대형 수조로서, 내부에는 상기 실리카 용액과 같은 내부식성 용액이 담겨진다.The immersion tank 20 is a large water tank having a rectangular parallelepiped shape in which an upper portion is opened, and a corrosion resistant solution such as the silica solution is contained therein.

상기 침적조(20)의 바닥에는 관통홀(21)이 형성되는데, 상기 서포터(13)가 상기 관통홀(21)을 관통하는 상태로 설치된다.A through hole 21 is formed at the bottom of the deposition tank 20, and the supporter 13 is installed in a state of passing through the through hole 21.

그리고, 상기 관통홀(21)에는 시일링(22)이 설치되어, 관통홀(21)과 서포터(13) 사이로 내부식성 용액이 누출이 방지된다.In addition, a sealing ring 22 is installed in the through hole 21 to prevent leakage of the corrosion resistant solution between the through hole 21 and the supporter 13.

상기 유압실린더(30)는 롤러테이블(10)이 설치된 바닥에 설치되며, 실린더로 드(31)가 상기 침적조(20)의 바닥 하면에 연결된다.The hydraulic cylinder 30 is installed on the floor where the roller table 10 is installed, and the cylinder rod 31 is connected to the bottom bottom of the deposition tank 20.

따라서, 도시되지 않은 유압공급수단에 의해 유압이 전달되면 내부의 상기 실린더로드(31)가 돌출되면서 상기 침적조(20)를 밀어 올려 상승시키게 된다.Therefore, when the hydraulic pressure is transmitted by the hydraulic supply means (not shown), the cylinder rod 31 therein protrudes and pushes up the deposition tank 20.

상기와 같은 구성의 침적장치에 의한 내부식성 용액 도포 과정을 살펴본다.It looks at the application of the corrosion-resistant solution by the deposition apparatus of the above configuration.

먼저, 템프코어 공정 후 냉각되면서 소정 길이로 절단된 철근(1)이 상기 롤러테이블(10)로 진입된다.First, the rebar 1 cut into a predetermined length while being cooled after the temper core process enters the roller table 10.

철근(1)이 롤러테이블(10)의 상부로 완전히 진입되면 롤러(11)의 회전이 정지되어 철근(1)의 이송을 일시 정지시킨다.When the reinforcing bar 1 completely enters the upper portion of the roller table 10, the rotation of the roller 11 is stopped to temporarily stop the transfer of the reinforcing bar 1.

이어, 상기 유압실린더(30)가 작동되어 실린더로드(31)가 상승함으로써 상기 침적조(20)가 상승한다.Subsequently, the hydraulic cylinder 30 is operated to raise the cylinder rod 31 so that the deposition tank 20 rises.

상기 침적조(20)가 도 3과 같이 완전히 상승하면, 상기 롤러(11)에 놓여 있는 철근(1)이 침적조(20)의 내부식성 용액에 완전히 잠긴다.When the immersion tank 20 is fully raised as shown in FIG. 3, the rebar 1 placed on the roller 11 is completely immersed in the corrosion resistant solution of the immersion tank 20.

상기의 상태에서 설정된 시간(통상 2~3초이나, 필요에 따라 증감될 수 있다.)이 경과되면, 상기 유압실린더(30)의 유압이 서서히 제거되어 침적조(20)가 하강하여 도 1의 상태로 원위치된다.When the time set in the above state (usually 2-3 seconds, but may be increased or decreased as necessary), the hydraulic pressure of the hydraulic cylinder 30 is gradually removed to lower the deposition tank 20 of FIG. It is returned to the state.

상기와 같이 철근(1)이 내부식성 용액에 잠겨 있는 동안 철근(1)의 전체 표면에는 빠짐없이 고르게 내부식성 용액이 도포된다.While the rebar 1 is immersed in the corrosion resistant solution as described above, the corrosion resistant solution is evenly applied to the entire surface of the rebar 1 without exception.

특히, 상기 침적장치는 철근(1)의 온도를 감안하여 용액이 신속하게 비정질 피막을 형성할 수 있는 위치에 설치된 것이므로 침적조가 상승하여 철근(1)이 용액 속에 잠겨 있는 시간과, 침적조가 다시 하강하는 시간 동안 철근 표면의 비정질 피막은 다른 곳에 묻어나지 않는 정도로 충분히 경화된다.In particular, since the deposition apparatus is installed at a position where the solution can quickly form an amorphous coating in consideration of the temperature of the rebar 1, the deposition tank is raised and the time when the rebar 1 is immersed in the solution and the deposition tank is lowered again. During this time, the amorphous coating on the surface of the reinforcing bar hardens enough to prevent it from being buried elsewhere.

따라서, 상기와 같이 침적조(20)가 하강하면, 상기 롤러테이블(10)이 다시 작동하여 철근(1)은 이후의 번들링장치로 이송된다.Therefore, when the deposition tank 20 is lowered as described above, the roller table 10 is operated again so that the reinforcing bar 1 is transferred to a subsequent bundling apparatus.

상기와 같이 철근(1)을 침적조에 완전히 담그어 내부식성 용액을 도포함으로써 철근(1)의 표면에 빠짐없이 내부식 피막을 형성할 수 있게 되어 내부식 품질이 향상되고, 보다 신속하게 내부식성 용액의 도포를 실시할 수 있게 된다.By completely immersing the reinforcing bar (1) in the immersion tank as described above, it is possible to form a corrosion-resistant film without falling into the surface of the reinforcing bar (1) to improve the quality of the corrosion, and to more quickly Application | coating can be performed.

또한, 종래 용액 분사의 경우와는 달리 분사에 의해 용액 입자가 공기중으로 비산되지 않으므로 작업 공간이 오염되는 현상이 발생하지 않는다.In addition, unlike the case of the conventional solution injection, since the solution particles are not scattered into the air by the injection, the phenomenon that the working space is contaminated does not occur.

또한, 철근(1)에 과량 도포된 용액도 하방으로 흘러 모두 침적조(20)에 다시 담겨지게 되므로 철근(1)에 도포되지 않은 용액은 전량 회수할 수 있게 되는 바, 내부식성 용액의 낭비를 방지할 수 있게 된다.In addition, since the solution applied excessively to the reinforcing bar 1 flows downwards and is all re-immersed in the deposition tank 20, the total amount of the solution not applied to the reinforcing bar 1 can be recovered. It becomes possible to prevent it.

한편, 상기 침적조(20)가 상승할 때 용액의 액위가 롤러(11) 설치 위치를 지나 철근(1) 높이까지 보다 원활하고 신속하게 상승할 수 있도록 도 4에 도시된 바와 같이 상기 롤러(11)에는 다수의 통공(11a)이 형성되어 있다.On the other hand, the roller 11 as shown in Figure 4 so that the liquid level of the solution can rise more smoothly and quickly to the height of the reinforcing bar 1 through the roller 11 installation position when the deposition tank 20 rises ), A plurality of through holes 11a are formed.

따라서, 침적조 상승시 상기 내부식성 용액이 롤러(11)의 사이 공간 뿐만 아니라 상기 통공(11a)을 통해서도 상승하게 되므로 보다 신속한 액위의 상승이 가능하여 철근(1)의 원활한 침적이 가능하다.Therefore, when the deposition tank rises, the corrosion resistant solution rises not only between the spaces between the rollers 11 but also through the through holes 11a, so that the liquid level can be raised more quickly, and smooth deposition of the rebar 1 is possible.

한편, 도 5에 도시된 바와 같이, 본 발명에 따른 침적장치는 일정 농도로 제조된 상기 내부식성 용액이 담겨져 있는 용액탱크(40)를 구비하며, 상기 용액탱크와 침적조(20) 사이에는 리턴배관(51)과 공급배관(52)으로 이루어진 순환배관(50) 이 설치된다.Meanwhile, as shown in FIG. 5, the deposition apparatus according to the present invention includes a solution tank 40 containing the corrosion resistant solution prepared at a predetermined concentration, and is returned between the solution tank and the deposition tank 20. A circulation pipe 50 consisting of a pipe 51 and a supply pipe 52 is installed.

그리고, 상기 리턴배관(51)에는 용액을 강제 순환시키기 위한 순환펌프(60)가 설치되고, 상기 공급배관(52)에는 용액탱크(40)로부터 침적조(20)로 내부식성 용액을 공급하기 위한 공급펌프(70)가 설치된다.The return pipe 51 is provided with a circulation pump 60 for forcibly circulating the solution, and the supply pipe 52 is provided for supplying a corrosion resistant solution from the solution tank 40 to the deposition tank 20. Feed pump 70 is installed.

상기 공급펌프(70)는 상기 순환펌프(60)의 흡입량과 공정 진행에 따른 용액 소비량의 합에 해당하는 만큼을 용액을 용액탱크(40)로부터 침적조(20)로 공급한다.The supply pump 70 supplies the solution from the solution tank 40 to the deposition tank 20 corresponding to the sum of the suction amount of the circulation pump 60 and the solution consumption amount according to the process progress.

그리고, 상기 용액탱크(40)에는 일정 농도로 제조된 내부식성 용액이 떨어지지 않도록 지속적으로 재보충된다.In addition, the solution tank 40 is continuously replenished so as not to fall off the corrosion resistant solution prepared at a certain concentration.

따라서, 상기 침적조(20)의 내부식성 용액은 지속적으로 순환되므로 항상 일정한 농도(내부식 피막 형성에 적합한 농도)를 유지할 수 있으며, 겨울철 동결이 방지된다.Therefore, since the corrosion resistant solution of the immersion tank 20 is continuously circulated, it can always maintain a constant concentration (concentration suitable for forming the corrosion resistant film), and freezing in winter is prevented.

한편, 도 6과 같이 상기 침적조(20)에 교반기(80)가 구비될 수 있다.On the other hand, a stirrer 80 may be provided in the deposition tank 20 as shown in FIG.

상기 교반기(80)는 침적조(20)의 측벽 상면에 설치된 마운팅브라켓(85; 교반기가 적절한 각도로 설치될 수 있도록 설치 좌면을 제공한다.)에 장착된다.The stirrer 80 is mounted on a mounting bracket 85 (provides an installation seating surface so that the stirrer can be installed at an appropriate angle) installed on the upper surface of the side wall of the deposition tank 20.

상기 교반기(80)는 침적조(20)의 전방과 후방의 측벽 상부를 따라 복수개 설치될 수 있다.The stirrer 80 may be provided in plural along the upper side of the side wall of the front and rear of the deposition tank 20.

따라서, 상기 교반기(80)가 지속적으로 용액을 혼합하여 줌으로써 침적조(20)내 내부식성 용액이 전체적으로 균일한 농도를 가지게 되어 철근(1)의 표면에 형성되는 내부식 피막의 기계적 성질도 균일하게 형성되어 표면 품질의 균일성이 향상되는 효과가 있다.Therefore, the stirrer 80 continuously mixes the solution so that the corrosion resistant solution in the deposition tank 20 has an overall uniform concentration, so that the mechanical properties of the corrosion resistant film formed on the surface of the rebar 1 are uniform.
