본 고안은 냉연도금강판에서 발생하는 녹(Rust)을 방지하는 장치에 관한 것으로, 보다 상세히는 산세탱크(P/L Tank)와 세정탱크(rinse tank)사이에 설치되어 냉연도금강판의 표면에서 발생하는 녹(Rust)을 제거하도록 재생(再生) 산(酸)을 공급하여 주는 스프레이 노즐에 관한 것이다.The present invention relates to a device for preventing rust generated in cold-rolled steel sheet, and more specifically, it is installed between the P / L tank and the rinse tank to be generated on the surface of the cold-rolled steel sheet. The present invention relates to a spray nozzle that supplies regenerated acid to remove rust.

일반적으르 냉연도금공장의 산세설비는 다음과 같다. 먼저 4개의 산세탱크(P/L Tank)와 3개의 세정탱크(Rinse Tank)가 갖춰지고, 소재강판이 4개의 산세탱크를 거친 다음 3개의 세정탱크를 거치고, 건조과정을 거쳐 도금공정으로 이송된다.In general, the pickling facilities of cold-rolled plating plants are as follows. First, 4 pickling tanks (P / L Tank) and 3 cleaning tanks (Rinse Tank) are equipped, and the material steel plate passes through 4 pickling tanks, then 3 cleaning tanks, and is dried and transferred to the plating process. .

이때, 산세탱크로는 재생산이 공급되어 산세작용이 이루어지면 세정탱크에서 소재강판에 부착된 재생산(염산) 및 이물질을 제거하기 위해 온수(Hot Water)를 소재표면에 도포하여 깨끗이 세척시키는 것이다. 따라서, 산세탱크로 부터 이송되는 소재강판에는 최소한의 염산과 이물질이 표면에 잔류하는 것이 요구되기 때문에 산세탱크와 세정탱크사이에는 링거롤(Wringer roll)이 설치되어 소재표면에 부착된 염산과 이물질을 제거하도록 되어있다. 상기와 같은 산세처리설비의 구성이 제3도 및 제4도에 도시되어 있다. 즉, 한쌍의 링거롤(100) (100')이 산세탱크(110)와 세정탱크(120)사이에 설치되고, 소재강판(130)이 링거롤 (100) (100')사이를 거쳐 세정탱크(120)로 이송되는 것이었다.At this time, the pickling tank is supplied with regeneration, and pickling action is performed to cleanly apply hot water to the material surface to remove regeneration (hydrochloric acid) and foreign matter attached to the material steel sheet in the cleaning tank. Therefore, since the minimum amount of hydrochloric acid and foreign substances are required to remain on the surface of the steel sheet conveyed from the pickling tank, a ringer roll is installed between the pickling tank and the cleaning tank to remove the hydrochloric acid and the foreign substances adhering to the material surface. It is supposed to be removed. The configuration of the pickling treatment system as described above is shown in FIG. 3 and FIG. That is, a pair of ringer rolls 100 and 100 'are installed between the pickling tank 110 and the cleaning tank 120, and the material steel plate 130 passes between the ringer rolls 100 and 100'. Was to be transferred to 120.

그러나, 상기 구조에는 여러가지 문제점이 있었다.However, there have been various problems with the structure.

특히, 일부의 냉연도금제품(Hot-Gi) 생산시에는 소재강판(130)의 이송속도가 현저히 저하되는 경우, 응축수가 산세탱크 뚜껑 (Tank cover) (110a)으로부터 링거롤 (100')과 감속롤 (Hold Down Roll) (110b)사이에서 소재강판(130)의 온도가 높고, 저속으로 링거롤(100) (100')사이를 통과하는 겨우, 링거롤(100) (100')과 감속롤 (110b)사이에서 소재강판(130)이 건조되어 산화피막이 헝성되며, 또한, 세정탱크 (1 20)의 세정수분사노즐(미도시)로 부터 비산되는 세정수가 링거롤(100')과 감속롤 (110b)사이에서 녹을 발생시키는 것이었다. 그리고, 링거롤(100)의 출측에 형성된 세정수 분사노즐(미도시)로 부터 바닥으로 떨어진 세정수가 산세탱크(110) 내부로 유입되어 pH 농도를 저하시키는 등의 문제점을 갖고 있는 것이었다. 따라서, 냉연재품의 품질이 현저히 저하되는 제품경쟁력이 낮아지는 큰 문제점을 갖추고 있는 것이다.In particular, during the production of some cold-rolled products (Hot-Gi), when the conveying speed of the material steel plate 130 is significantly reduced, the condensate is decelerated with the ringer roll (100 ') from the pickling tank cover (110a) The temperature of the material steel plate 130 is high between the roll down rolls 110b and only between the ringer rolls 100 and 100 'at a low speed, the ringer rolls 100 and 100' and the reduction rolls. Between 110b, the material steel plate 130 is dried to form an oxide film, and the washing water scattered from the washing water spray nozzle (not shown) of the washing tank 1 20 is ringer roll 100 'and the reduction roll. It was to generate rust between (110b). Then, the washing water dropped from the washing water injection nozzle (not shown) formed on the exit side of the ringer roll 100 flows into the pickling tank 110 to lower the pH concentration. Therefore, there is a big problem that the product competitiveness that the quality of the cold rolled material is significantly reduced.

본 고안은 상기와 같은 문제점을 해소하기 안출된 것으로서, 링거롤과 산세탱크의 감속롤 사이에서 녹의 발생을 방지하여 소재강판의 품질을 향상시켜 결과적으로 산세작업을 효과적으로 수행하고 제품경쟁력을 높일수 있는 (Rust) 발생방지용 스프레이 노즐을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, to prevent the occurrence of rust between the ringer roll and the deceleration roll of the pickling tank to improve the quality of the material steel plate, which can effectively perform the pickling operation and improve the product competitiveness ( Rust) The purpose is to provide a spray nozzle for preventing occurrence.

상기 목적을 달성하기 위하여 본 고안은 링거롤과 감속롤 사이에서 소재 강판의 상하면에 재생산(再生酸)(recovered Acid)을 분사시켜주는 다수개의 노즐이 길이방향으로 장착된 한쌍의 노즐부재와 상기 노즐부재로 재생산 집수조로부터 재생산을 가압공급하는 재생산 공급펌프를 갖추어 소재강판의 녹과 산화피막을 제거시킴을 특징으로 하는 녹발생방지용 스프레이 노즐을 마련함에 의한다.In order to achieve the above object, the present invention provides a pair of nozzle members having a plurality of nozzles mounted in a longitudinal direction between the ringer roll and the reduction roll to inject the recovered acid on the upper and lower surfaces of the steel sheet. The member is equipped with a regeneration supply pump for pressurizing and supplying regeneration from the regeneration collection tank as a member, thereby providing a rust prevention spray nozzle, characterized in that to remove rust and oxide film of the steel sheet.

제1도 및 제2도를 참조하여 본 고안을 보다 상세히 설명한다. 본 고안의 스프레이 노즐(1)은 소재강판(130)의 상,하면에 재생산을 분사시키는 한쌍의 노즐부재(10) (10')와 상기 노즐부재 (10) (10')로 재생산을 공급하는 재생산 공급펌프(20)를 갖추고, 각각 자동제어밸브(25)(30)에 의해 개폐가 이루어지도록 된다. 상기 노즐부재 (1 0)(10')는 링거롤(100)(100')의 전체폭에 걸쳐서 연장되는 길이를 갖춘 원통형 몸체부에 일정각도로 소재강판(130)을 향해 형성된 다수개의 노즐(10a)을 각각 갖추고 있다. 또한 연결관(33)을 매개로 재생산 공급펌프(20)와 결합되고, 상기 연결관(33)에는 전기적으로 작동되는 자동제어밸브(25) (30)가 갖춰짐으로서 개폐작동이 이루어진다. 또한, 상기 재생산 공급펌프(20)는 재생산 집수조(미도시)로 부터 재생산을 가압공급하고, 따라서 노즐부재(10) (10')의 노즐(10a)을 통해 적절한 시기에 재생산을 소재강판(130)의 상,하면에 분사도포시킨다. 한편, 한쌍의 링거롤(100) (100')이 위치된 하부 바닥면에는 내산벽돌(Brick)로 된 돌출턱 (40)이 링거롤(100) (100')을 길이방향으로 따라서 연장되어 있다.The present invention will be described in more detail with reference to FIGS. 1 and 2. The spray nozzle 1 of the present invention supplies a regeneration to a pair of nozzle members 10 and 10 'and a nozzle member 10 and 10' that injects regeneration to the upper and lower surfaces of the material steel plate 130. The regeneration supply pump 20 is provided, and is opened and closed by automatic control valves 25 and 30, respectively. The nozzle member (10) (10 ') is a plurality of nozzles formed toward the material steel plate 130 at a predetermined angle to the cylindrical body portion having a length extending over the entire width of the ringer roll (100, 100') ( 10a) respectively. In addition, coupled to the regeneration supply pump 20 via the connecting pipe 33, the connecting pipe 33 is equipped with an electrically operated automatic control valve 25, 30 is made to open and close operation. In addition, the regeneration supply pump 20 pressurizes the regeneration from a regeneration sump (not shown), and thus reproduces the regeneration at an appropriate time through the nozzle 10a of the nozzle member 10 (10 '). Spray on top and bottom of the On the other hand, a protruding jaw 40 made of acid-resistant brick extends along the length of the ringer rolls 100 and 100 'on the lower bottom surface where the pair of ringer rolls 100 and 100' is located. .

이하, 본 고안의 작용 및 효과에 대하여 설명한다.Hereinafter, the operation and effects of the present invention will be described.

소재강판(130)의 이송속도가 현저히 저하되어, 응축수가 산세탱크 뚜껑(110a)으로 부터 소재강판(130)의 상부면에 낙하되어 녹을 발생시키고, 또한 소재강판(130)의 높은 온도로 인하여 상,하면에 산화피막이 생성되는 경우에도, 링거롤(100) (100')전단에 설치된 본 고안의 스프레이노즐(1)로 부터 공급되는 재생산에 의하여 발생된 녹이 제거된다. 또한, 세정수에 의하여 발생되는 소재강판(130)의 녹도 본 고안에 의해 공급되는 재생산에 의해서 제거됨은 물론이다. 한편, 링거롤(100) (100')하부에 위치된 돌출턱 (40)은 내산벽돌로 축조되기 때문에 본 고안의 스프레이노즐(1)로 부터 공급되는 재생산에 의해서 손상받지 않게되고, 세정수 분사노즐로 부터 공급된 세정수가 산세탱크(110)로 유입되는 것을 효과적으로 차단한다.The conveying speed of the material steel sheet 130 is significantly lowered, condensed water falls from the pickling tank cap 110a to the upper surface of the material steel sheet 130 to generate rust, and also due to the high temperature of the material steel sheet 130 Also, even when an oxide film is formed on the lower surface, rust generated by regeneration supplied from the spray nozzle 1 of the present invention installed at the front end of the ringer rolls 100 and 100 'is removed. In addition, of course, the rust of the material steel sheet 130 generated by the washing water is also removed by the reproduction supplied by the present invention. On the other hand, since the protruding jaw 40 located below the ringer rolls 100 and 100 'is constructed of acid-resistant brick, it is not damaged by the regeneration supplied from the spray nozzle 1 of the present invention, and the spraying of the washing water. The cleaning water supplied from the nozzle effectively blocks the pickling tank 110 from flowing into the pickling tank 110.

상기에서와 같이 본 고안에 의하면, 링거롤(100) (100')과 감속롤(110b)사이에서, 특히, 링거롤(100) (100')과 인접한 전방위치에서 재생산을 소재강판(130)의 상,하면에 골고루 분사도포시켜 주기때문에 링거롤(100')과 감속롤(110b)사이에서 발생된 어떠한 녹이나 산화피막도 효과적으로 제거되는 실용상의 효과가 얻어진다.According to the present invention as described above, between the ringer roll (100) (100 ') and the reduction roll (110b), in particular, in the front position adjacent to the ringer roll (100) (100') the material steel sheet 130 Since the spray coating is evenly applied to the upper and lower surfaces, a practical effect is obtained in which any rust or an oxide film generated between the ringer roll 100 'and the reduction roll 110b is effectively removed.

또한, 돌출턱 (40)에 의하여 세정수가 산세탱크(110)로 유입되지 않기 때문에 산세액의 pH 농도가 저하되지않는 실용상의 효과도 얻어진다.In addition, since the washing water does not flow into the pickling tank 110 by the protruding jaw 40, a practical effect of not lowering the pH concentration of the pickling liquid is also obtained.

이때 상기 스프레이노즐(1)은 필요한 경우 즉, 소재강판(130)의 이송속도가 저하되어, 녹이나 산화피막이 표면에 발생될 수 있는 조건에 한하여 자동제어밸브(25) (30)와 재생산공급펌프(20)를 선택적으로 가동시켜 설비가동의 효율성을 향상시킬 수 있음은 물론이다.At this time, the spray nozzle (1), if necessary, that is, the feed rate of the material steel plate 130 is lowered, the automatic control valve (25) 30 and the regeneration supply pump only in the condition that rust or oxide film may occur on the surface Of course, by selectively operating the (20) can be improved the efficiency of the equipment operation.
