Description

드로스 부착 방지형 싱크롤장치{Sink roll apparatus for preventing dross attachment}[0001] The present invention relates to a sink roll apparatus for preventing dross attachment,

본 발명은 싱크롤에 관한 것으로, 더욱 상세하게는 도금욕조내의 용융금속의 유동으로 플로팅드로스(Floating dross)가 부착되는 것을 방지할 수 있는 드로스 부착 방지형 싱크롤장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sink roll, and more particularly, to a sink roll prevention type sink roll apparatus capable of preventing a floating dross from adhering to a molten metal in a plating bath.

일반적으로 용융금속 도금 형태 중 하나가 강판의 표면에 아연을 도금하기 위하여 용융아연을 채운 도금욕조를 강판이 통과하면서 표면에 아연을 도금하는 아연도금강판의 도금형태이다. 특히, 강판을 연속적으로 도금욕조를 통과시키어 연속적으로 도금하는 것을 연속용융 도금라인이라 하고 통상 'CGL'(Continuous Galvanizing Line)이라고도 한다.Generally, one of the forms of molten metal plating is a galvanized steel plate plating type in which zinc is plated on the surface of a steel plate while passing through a galvanizing bath filled with molten zinc to coat zinc on the surface of the steel plate. In particular, continuously plating a steel sheet by passing through a plating bath continuously is referred to as a continuous galvanizing line (CGL).

도 1을 참조하면, 용융아연도금라인(CGL)의 도금욕조와 이 도금욕조에 배치된 도금욕조 침지롤들을 도시하고 있다. 즉, 연속 강판(10)이 풀림 장치(미도시)로부터 연속적으로 공급되어 가열로(미도시)와 연결되고 도금욕조(11)의 탕면에 침지되는 스나우트(13)를 통하여 용융금속(아연)(12)이 채워진 도금욕조(11)로 도입된다.Referring to FIG. 1, there is shown a plating bath of a hot dip galvanizing line (CGL) and plating bath dipping rolls disposed in the plating bath. That is, the continuous steel plate 10 is continuously supplied from a uncoiling apparatus (not shown) and connected to a heating furnace (not shown), and molten metal (zinc) is supplied through a Snart 13 immersed in the bath surface of the plating bath 11. [ Is introduced into the plating bath (11) filled with the plating solution (12).

그리고, 상기 도금욕조(11)내에 침지된 침지롤 예컨대, 싱크롤(14)과 그 직상부의 안정화 롤(15)에 의해 강판(10)은 그 패스 라인이 도금욕조 직상부로 수직하게 변경되면서 도금욕조를 통하여 연속 이송된다. 이때, 도금욕조(11)내에 채워진 용융금속(12) 예를 들어, 용융아연이 강판(10)의 표면에 부착 도금된다.The pass line of the steel sheet 10 is vertically changed to the upper portion of the plating bath by the immersion rolls such as the sink rolls 14 and the stabilization rolls 15 directly above the immersion rolls immersed in the plating baths 11 And is continuously transported through the plating bath. At this time, the molten metal 12, for example, molten zinc filled in the plating bath 11 is plated on the surface of the steel sheet 10.

이후, 싱크롤(14)을 통과한 강판(10)은 그 직상부 한쌍의 안정화 롤(15)사이를 통과하면서 휨 등이 교정되고, 이와 같이 교정된 강판(10)은 도금욕조(11) 직상부의 에어나이프(16)를 통과하면서 용융아연의 표면 부착량이 조절된다.The steel plate 10 having passed through the sink roll 14 is then subjected to a warping or the like while being passed between a pair of stabilizing rolls 15 thereabove. The surface adhesion amount of the molten zinc is adjusted while passing through the upper air knife 16.

이후, 강판은 냉각되고 고형화되고, 이후 권취장치(미도시)를 통하여 코일형태로 권취된다.Thereafter, the steel sheet is cooled and solidified, and then wound in the form of a coil through a winding device (not shown).

따라서, 도금욕조 롤인 싱크롤(14)은 강판(10)의 도금욕조 인입 후 수직 이송의 방향 전환을 가능하게 하고, 그 직상부에 있는 안정화 롤(15)은 고온 상태인 강판(10)의 뒤틀림, 반곡을 교정하고 진행 중 진동(떨림) 발생을 억제한다.Therefore, the sink roll 14, which is the plating bath roll, is capable of switching the direction of the vertical conveyance after the introduction of the plating bath of the steel plate 10, and the stabilization roll 15 immediately above the stabilization roll 15, , Corrects the bend and suppresses the occurrence of vibration (vibration) during the process.

상술한 해결하고자 하는 과제를 달성하기 위하여, 본 발명은 도금욕조 내부에 설치되는 싱크롤에 드로스가 부착되는 것을 방지하는 싱크롤장치에 있어서, According to an aspect of the present invention, there is provided a sink roll apparatus for preventing dross from adhering to a sink roll installed in a plating bath,

상기 싱크롤에 결합되어 상기 싱크롤과 함께 회전가능한 롤축과; 상기 롤축의 양단에 설치되는 슬리브와; 상기 슬리브의 외주면에 설치되어 상기 슬리브 및 상기 롤축을 지지하는 부쉬와; 상기 롤축의 길이방향으로 상기 도금용조 내면을 향해 상기 슬리브에서 연장 형성되는 연장부를 포함하되,A roll shaft coupled to the sink roll and rotatable together with the sink roll; A sleeve installed at both ends of the roll shaft; A bush installed on an outer circumferential surface of the sleeve to support the sleeve and the roll shaft; And an extension extending from the sleeve toward the plating bath inner surface in the longitudinal direction of the roll axis,

상기 연장부는 상기 롤축의 길이방향으로 나사선이 형성된 것을 특징으로 하는 싱크롤장치를 제공한다.And the extension portion is formed with a screw thread in the longitudinal direction of the roll shaft.

여기서, 상기 연장부는 상기 도금욕조의 내면 방향으로 단면적이 감소하는 형상을 가질 수 있다.Here, the extension may have a shape in which the cross-sectional area decreases in the direction of the inner surface of the plating bath.

도 1은 연속용융 도금라인을 나타낸 도면.
도 2는 본 발명의 일실시예에 따른 드로스 부착 방지형 싱크롤장치의 구성도.1 shows a continuous hot-dip plating line;
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

도 1을 참조하면, 용융아연도금공정의 도금욕조(11) 내부에는 강판의 이동방향을 변경시켜주는 싱크롤(14) 1개와 강판의 진동과 반곡 및 패스 라인(Pass Line)을 조정할 수 있는 안정화롤(15) 2개로 구성되어 있으며, 도금욕조(11) 안에 잠겨서 동작하도록 되어 있다. 1, in the plating bath 11 of the hot-dip galvanizing process, there are provided a sink roll 14 for changing the moving direction of the steel sheet, and a stabilization unit 14 for adjusting the vibration, bending and pass line of the steel sheet Rolls 15, and is operated in a state of being immersed in the plating bath 11.

그러나, 도금욕조(11) 내부라는 위치적 특성으로 인하여 용융아연도금라인(CGL)의 대표적인 드로스 결함의 원인인 플로팅 드로스(Floating Dross)가 도금욕조(11) 내부의 유동에 의하여 싱크롤(14) 표면에 부착하여 강판의 표면에 드로스 찍힘과 드로스 부착을 발생시킨다.
However, due to the positional property inside the plating bath 11, a floating dross, which is a cause of typical dross defects in the hot dip galvanizing line (CGL), is generated by the flow in the plating bath 11, 14) It attaches to the surface, causing the surface of the steel plate to be subjected to droplet deposition and dross adhesion.

이하, 상술한 문제점을 해결하기 위해 첨부된 도면을 참조하여, 본 발명에 따른 드로스 부착 방지형 싱크롤장치의 실시 예를 설명한다.In order to solve the above-mentioned problems, an embodiment of a drift prevention type sink roll apparatus according to the present invention will be described with reference to the accompanying drawings.

도 2를 참조하여, 본 발명의 일실시예에 따른 드로스 부착 방지형 싱크롤장치는 도금욕조(100) 내부에 설치되는 싱크롤(200)에 드로스가 부착되는 것을 방지하는 싱크롤장치에 있어서 롤축(300), 슬리브(400), 부쉬(500) 및 연장부(600)를 포함한다.Referring to FIG. 2, a sink roll-preventing type sink roll apparatus according to an embodiment of the present invention is a sink roll apparatus that prevents dross from adhering to a sink roll 200 installed inside a plating bath 100 A roll shaft 300, a sleeve 400, a bush 500, and an extension 600.

롤축(300)은 싱크롤(200)에 연결되어 싱크롤(200)과 함께 회전 가능하다. 즉, 롤축(300)이 회전함으로써 롤축(300)에 연결된 싱크롤(200)이 회전한다.The roll shaft 300 is connected to the sink roll 200 and is rotatable together with the sink roll 200. That is, as the roll shaft 300 rotates, the sink roll 200 connected to the roll shaft 300 rotates.

슬리브(400)는 롤축(300)의 양단에 설치된다. 즉, 슬리브(400)는 롤축(300)의 외주면에 끼워지며, 이때, 슬리브(400)는 내마모성이 우수한 재질인 것이 바람직하다.The sleeve 400 is installed at both ends of the roll shaft 300. That is, the sleeve 400 is fitted to the outer circumferential surface of the roll shaft 300, and at this time, the sleeve 400 is preferably made of a material excellent in abrasion resistance.

부쉬(500)는 슬리브(400)의 외주면에 설치되어 슬리브(400) 및 롤축(300)을 지지하면서 미끄럼작용을 일으키는 베어링수단이다. 이때, 부쇠(500)는 내마모성이 우수한 재질인 것이 바람직하다.The bush 500 is provided on the outer circumferential surface of the sleeve 400 and is a bearing means for causing sliding action while supporting the sleeve 400 and the roll shaft 300. At this time, it is preferable that the weft 500 is made of a material excellent in abrasion resistance.

연장부(600)는 원통형상으로 롤축(300)의 길이방향으로 도금욕조(100)의 내면을 향해 슬리브(400)에서 연장 형성되며, 연장부(600)의 외주면에는 롤축(300)의 길이방향으로 나사선이 형성된다. 이때, 연장부(600)는 롤축(300)의 길이방향으로 단면적이 감소되는 형상을 갖는 것이 바람직하다.The extension part 600 extends from the sleeve 400 toward the inner surface of the plating bath 100 in the longitudinal direction of the roll shaft 300 and extends in the longitudinal direction of the roll shaft 300 on the outer peripheral surface of the extension part 600. [ A thread is formed. At this time, it is preferable that the extension part 600 has a shape in which the cross-sectional area decreases in the longitudinal direction of the roll shaft 300.

결과적으로, 싱크롤(200)의 회전시에 연장부(600)도 회전하게 되고, 외주면에 나사선이 형성된 연장부(600)가 회전함에 따라 도금욕조(100) 내면 방향으로 유동이 발생한다. 이러한 유동은 도금욕조(100) 내면에서 반사되어 나오는 반사 유동과 방향이 반대이므로 반사 유동의 크기를 작게 만든다.
As a result, when the sink roll 200 rotates, the extension portion 600 also rotates. As the extension portion 600 having the threaded portion on the outer circumferential surface rotates, the flow occurs in the inner surface direction of the plating bath 100. Since the flow is opposite to that of the reflection flow reflected from the inner surface of the plating bath 100, the size of the reflection flow is made small.

본 실시예에 따른 드로스 부착 방지형 싱크롤장치는 도금욕조(100) 내면에서 반사되어 나오는 반사유동이 싱크롤(200) 방향으로 이동하는 것을 차단하는 차폐판(700)을 더 포함할 수 있다.The droplet adhesion prevention type sink roll apparatus according to the present embodiment may further include a shield plate 700 for blocking the reflection flow reflected from the inner surface of the plating bath 100 from moving toward the sink roll 200 .

차폐판(700)은 부쉬(500)에 고정설치되며, 반사유동이 싱크롤(200) 방향으로 이동하는 것을 차단한다. 이때, 차폐판은 반사 유동과 접촉되는 면적이 넓어지도록 싱크롤(200)의 길이방향에 대하여 경사진 것이 바람직하다. 구체적으로, 부쉬(500)의 외측면에는 싱크롤(200)의 길이방향을 기준으로 도금욕조(100)의 내면 방향으로 경사를 가지는 연결프레임(710)의 일단이 연결되며, 연결프레임(710)의 타단에는 차폐판(700)이 연결된다.The shield plate 700 is fixed to the bush 500 and blocks the reflection flow from moving in the direction of the sink roll 200. At this time, it is preferable that the shielding plate is inclined with respect to the longitudinal direction of the sink roll 200 so that an area of contact with the reflection flow becomes wider. Specifically, one end of the connection frame 710 having an inclination in the inner surface direction of the plating bath 100 is connected to the outer surface of the bush 500 with respect to the longitudinal direction of the sink roll 200, The shield plate 700 is connected to the other end of the shield plate 700.

결과적으로, 차폐판(700)은 도금욕조(100) 내면에서 반사되어 싱크롤(200)오 이동하는 반사 유동을 차단함으로써 플로팅 드로스에 의한 영향을 최소화한다.
As a result, the shielding plate 700 minimizes the influence of the floating dross by blocking the reflection flow that is reflected from the inner surface of the plating bath 100 and moves to the sink roll 200.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
