도 1은 도금포트를 도시한 도면이다.1 shows a plating port.
도 1을 참조하면, 도금포트(10)의 내부에 싱크롤(11)이 배치된다. 도금포트(10)의 측면에는 스나우트(20)가 배치된다. 그리고, 도금포트(10)의 상부에는 에어 나이프(30)가 배치된다. 강판(1)은 싱크롤(11)의 회전에 의해 용융 아연에 잠기었다가 에어 나이프(30)측으로 이동하게 된다.Referring to FIG. 1, the sink roll 11 is disposed inside the plating port 10. The snout 20 is disposed on the side surface of the plating port 10. The air knife 30 is disposed above the plating port 10. The steel sheet 1 is immersed in molten zinc by the rotation of the sink roll 11 and then moved to the air knife 30 side.
도 2는 도금포트 내의 유동을 도시한 도면이다.2 shows the flow in the plating port.
도 2를 참조하면, 싱크롤(11)의 회전에 의해 강판(1)이 이동하고 강판(1)의 이동에 의해 도금포트 내부에 용융 아연의 유동이 발생한다. 구체적으로 강판(1)은 스나우트(20)를 거쳐 도금포트(10) 내부에 침적된 이후, 에어 나이프(30) 측으로 올라가게 되는데, 이러한 강판(1)의 흐름과 싱크롤(11)의 회전으로 인하여 도금포트(10) 내부에는 영역별로 유동패턴이 달리 나타날 수 있다.Referring to FIG. 2, the steel sheet 1 is moved by the rotation of the sink roll 11, and the molten zinc flows inside the plating port by the movement of the steel sheet 1. Specifically, after the steel plate 1 is deposited in the plating port 10 through the snout 20, the steel plate 1 rises toward the air knife 30. The flow of the steel plate 1 and the rotation of the sink roll 11 are performed. As a result, a flow pattern may be differently formed for each region in the plating port 10.
예를 들어, 유동패턴을 달리하는 영역은 강판(1)과 싱크롤(11)의 위치를 기준으로 도 2에서 도시한 바와 같이, A영역과, B영역과, C영역으로 구분될 수 있다. 이중 B영역은 싱크롤(11)의 위치와 강판(1)의 위치로 인하여 제한된 영역에서 용융아연의 유동이 맴도는 패턴이 발생하게 된다.For example, a region having a different flow pattern may be divided into an A region, a B region, and a C region, as shown in FIG. 2, based on the positions of the steel plate 1 and the sink roll 11. The double B region has a pattern in which the flow of molten zinc revolves in a limited region due to the position of the sink roll 11 and the position of the steel sheet 1.
도 3은 강판의 찍힘성 결함을 나타낸 사진이다.Figure 3 is a photograph showing the flaw defect of the steel sheet.
이러한 B영역의 유동 패턴은 부유드로스가 밀집되어 맴돌게 되고, 이러한 부유드로스는 강판(1)과 싱크롤(11) 사이로 유입되어 도 3에서 도시한 바와 같은 강판(1)의 찍임성 결함(S)을 유발하게 된다.The flow pattern of the region B is caused by floating dross dense, and the floating dross flows in between the steel sheet 1 and the sink roll 11 to form a defect (S) of the steel sheet 1 as shown in FIG. Will cause).
B영역에서는 부유드로스의 밀집도가 높고 강판(1)과 싱크롤(11)사이로 용융아연이 빨려 들어가는 유동이 발생하기 때문에 부유드로스에 의한 찍임성 결함이 A영역이나, B영역보다 상대적으로 크게 발생하는 문제가 발생한다.In the region B, the dross density of the floating dross is high, and the flow of molten zinc is sucked between the steel plate 1 and the sink roll 11, so that the drawability defect caused by the floating dross is relatively larger than that of the region A or B. There is a problem that occurs.
본 발명은 이러한 문제점을 해결하기 위하여, B영역의 부유드로스를 집중적으로 제거하고자 안출된 것이다.In order to solve this problem, the present invention is intended to intensively remove the floating dross in the B region.

도 13은 도 10에서 도시한 부유드로스 제거장치의 정면도이다.FIG. 13 is a front view of the floating dross removing apparatus illustrated in FIG. 10.
도 13을 참조하면, 2개의 드로스 포집부(100A,100B)는 도금포트(10)의 길이방향(도 13의 x축방향)으로 동일한 위치에 배치되기 때문에, 도 2의 B영역에서 부유드로스의 포집영역이 한정적일 수 있다.Referring to FIG. 13, since the two dross collecting portions 100A and 100B are disposed at the same position in the longitudinal direction (x-axis direction of FIG. 13) of the plating port 10, they are floated in the region B of FIG. 2. Loss collection area may be limited.
도 14는 본 발명의 바람직한 부유드로스 제거장치의 또 다른 변형례를 도시한 도면이고, 도 15는 도 14에서 도시한 부유드로스 제거장치의 측면도이고, 도 16은 위치가 상이한 2개의 드로스 포집부의 포집영역을 도시한 도면이다. 14 is a view showing another modified example of the preferred floating dross removing apparatus of the present invention, Figure 15 is a side view of the floating dross removing apparatus shown in Figure 14, Figure 16 is two dross in different positions It is a figure which shows the collection area | region of a collection part.
도 14 내지 도 16을 참조하면, 본 발명의 바람직한 부유드로스 제거장치의 또 다른 변형례로서, 제1 스크류(122)에 2개의 드로스 포집부(100A,100B)를 구비하고, 각각의 2개의 드로스 포집부(100A,100B)가 도금포트(10)의 길이방향(도 14의 x축방향)을 기준으로 그 위치가 상이하게 형성될 수 있다.Referring to Figures 14 to 16, as another variant of the preferred suspended dross removal apparatus of the present invention, the first screw 122 is provided with two dross collecting portions (100A, 100B), each of the two The dross collecting portions 100A and 100B may be formed in different positions with respect to the longitudinal direction (x-axis direction of FIG. 14) of the plating port 10.
예를 들어, 2개의 제1 이송블록(123A,123B)의 길이(D1,D2)가 각각 상이하여 2개의 드로스 포집부(100A,100B)의 위치가 상이하게 배치될 수 있다. 따라서, 도 16을 참조하면, 드로스 포집부(100A,100B)에 의한 드로스 포집영역(P)이 도금포트(10)의 길이방향을 기준으로 보다 넓게 확장될 수 있다. 도금포트의 폭 방향(도 16의 y축 방향)으로 이동하는 드로스 포집부(100A,100B)의 움직임을 고려하면, 이와 같은 구성은 도 2의 B영역에서 보다 효과적으로 부유드로스를 제거할 수 있는 구성이다.For example, the lengths D1 and D2 of the two first transfer blocks 123A and 123B are different from each other, so that the positions of the two dross collecting units 100A and 100B may be different from each other. Therefore, referring to FIG. 16, the dross collecting area P by the dross collecting parts 100A and 100B may be wider than the length direction of the plating port 10. Considering the movement of the dross collecting portions 100A and 100B moving in the width direction (y-axis direction of FIG. 16) of the plating port, such a configuration can remove floating dross more effectively in the region B of FIG. It is a composition.
