일반적으로, 전기강판 소재인 열연강판의 표면에는 산화 스케일이 다량 부착되어 있어 품질저하의 요인이 된다.In general, a large amount of oxide scale is attached to the surface of the hot rolled steel sheet, which is an electrical steel sheet material, which causes deterioration of quality.

따라서, 상기 열연강판을 산세하기 전에 미세한 쇠구슬을 공기와 함께 그 표면에 분사시켜 충돌시 발생하는 충격에 의해 열연강판의 표면에 부착된 산화 스케일을 제거하게 된다.Therefore, before pickling the hot rolled steel sheet, fine iron beads are sprayed on the surface together with air to remove the oxidized scale attached to the surface of the hot rolled steel sheet by the impact generated during the collision.

이러한 산화 스케일 제거에 사용되는 숏 블라스트 분사장치는 예컨대, 도 1에 도시된 바와 같이, 열연강판(1)이 산세조로 진입하기 전에 숏 블라스트존(2)이 마련되고, 상기 숏 블라스트존(2)에는 일정간격을 두고 다수의 분사노즐(3)이 배열되며, 상기 분사노즐(3)은 숏 블라스트용 쇠구슬을 공급하는 메인공급관(4)에 연결되는 구성으로 이루어져 공급된 미세한 크기의 쇠구슬인 숏 볼을 열연강판(1) 표면에 분사함으로써 숏 블라스트를 수행하였다.In the shot blast injector used to remove the oxidized scale, for example, as illustrated in FIG. 1, the shot blast zone 2 is provided before the hot rolled steel sheet 1 enters the pickling bath, and the shot blast zone 2 is provided.

There were disadvantages and disadvantages that the injection nozzle 3 was easily clogged.

뿐만 아니라, 분사노즐(3)은 고정형이기 때문에 열연강판(1)의 통판속도에만 의지할 뿐 자체적으로 유동성을 갖지 못해 산화 스케일 제거에 따른 효율이 매우 낮다는 단점도 있었다.In addition, since the injection nozzle 3 is fixed, it relies only on the plate speed of the hot-rolled steel sheet 1 and does not have fluidity.

이때, 상기 분사노즐(400)은 그 일단이 상기 숏 블라스트존(2)에 끼워지는 형태를 갖게 되는 바, 이는 상기 본체하우징(300)의 선단이 상기 숏 블라스트존(2)의 일측면을 관통하여 1점 지지되는 형태로 고정되기 때문이다.At this time, the injection nozzle 400 has a shape that one end is fitted to the short blast zone (2), which is the front end of the main housing 300 penetrates one side of the shot blast zone (2) This is because it is fixed in the form of one point of support.

뿐만 아니라, 상기 분사노즐(400)의 외주면 적소에는 나사산(410)이 형성되도록 하여 상기 본체하우징(300)과 나사체결 방식에 의해 고정되도록 함으로써 상기 분사노즐(400)의 선단 노출 길이를 가변시킬 수 있도록 구성함이 더욱 바람직하다.In addition, the threaded portion 410 is formed on the outer circumferential surface of the injection nozzle 400 so that the tip exposure length of the injection nozzle 400 can be varied by being fixed by the main body housing 300 and the screwing method. It is more preferable to configure so that.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

구동모터(310)가 구동되면 그 회전축(320)에 고정된 구동워엄기어(330)가 회전되고, 이와 맞물린 워엄기어(340)가 회전되면서 종동축(350)을 회전시키게 된다.When the driving motor 310 is driven, the drive worm gear 330 fixed to the rotating shaft 320 is rotated, and the worm gear 340 engaged with the drive shaft 310 is rotated to rotate the driven shaft 350.

또한, 상기 종동축(350)의 회전에 따라 그 하단에 고정된 원판(360)이 회전되게 되고, 이에 편심 링크된 작동로드(370)는 상기 원판(360)의 직경범위 내에서 대략 타원형태를 그리면서 서브고정축(210)을 중심점으로 하여 회전유동되게 된다.In addition, as the driven shaft 350 rotates, the disc 360 fixed to its lower end is rotated, and the eccentrically linked actuating rod 370 has an approximately elliptical shape within the diameter range of the disc 360. In the meantime, the rotation of the sub-fixed shaft 210 as the center point.

동시에, 상기 종동축(350)은 상기 본체하우징(300)에 축설되어 있으므로 상기 본체하우징(300)도 동일한 유동을 하게 되는데, 이때 상기 본체하우징(300)의 회전중심은 메인고정축(200)이 되게 된다.At the same time, since the driven shaft 350 is installed in the main body housing 300, the main housing 300 also has the same flow, and the rotation center of the main housing 300 is the main fixed shaft 200. Will be.

아울러, 상기 본체하우징(300)의 유동은 다시 이에 고정된 유동안내축(220)의 회전유동도 유도하게 되는데 이때 상기 유동안내축(220)은 가이드홈(120)에 구속되어 있으므로 상기 유동안내축(220)은 상기 가이드홈(120)을 따라 유동되게 되고, 또한 상기 가이드홈(120)의 내부 바닥면은 상하로 굴곡(122)되어 있으므로 상기 유동안내축(220)은 상하방향으로 출렁거리게 되고, 이는 다시 본체하우징(300)을 상하로 흔들게 된다.In addition, the flow of the main body housing 300 also induces rotational flow of the flow guide shaft 220 fixed thereto. In this case, the flow guide shaft 220 is constrained to the guide groove 120 so that the flow guide shaft 220 is to be flowed along the guide groove 120, and also because the inner bottom surface of the guide groove 120 is bent up and down 122, the flow guide shaft 220 is rocking in the vertical direction , This again shakes the body housing 300 up and down.

따라서, 분사노즐(400)을 통해 분사되는 숏볼(B)은 본체하우징(300)의 유동형태로 분사되게 되고, 이에 따라 열연강판(S)의 표면은 구석구석까지 균일하게 디스케일(Descale)되게 된다.Therefore, the shot ball B injected through the injection nozzle 400 is injected in the flow form of the main body housing 300, and thus the surface of the hot rolled steel sheet S is uniformly descaled to every corner. do.

뿐만 아니라, 유동 분사 방식이므로 숏볼에 의한 노즐 막힘현상도 방지되게 된다.In addition, the nozzle is blocked due to the shot ball because of the flow injection method.

이상에서 상세히 설명한 바와 같이, 본 발명은 숏 블라스트 분사노즐을 상하좌우로 회전유동시키면서 숏볼을 분사하므로 열연강판 표면의 산화 스케일을 온전히 제거하여 품질향상은 물론 숏볼 분사시 압력을 일정하게 유지하여 노즐 막힘현상도 방지하게 되므로 생산성 향상, 산세력 확보에 커다란 효과가 있다.As described in detail above, the present invention sprays shot balls while rotating the shot blast nozzles up, down, left, and right so that the oxidation scale on the surface of the hot rolled steel sheet is completely removed to improve the quality as well as to maintain a constant pressure during shot spraying, thereby clogging the nozzles. It also prevents the phenomenon, which has a great effect on improving productivity and securing pickling forces.
