Claims (3)
- 연속주조 작업시 턴디쉬에서 몰드로 주입되는 용강의 흐름에 편류(bias flow)가 발생하지 않도록 된 슬라이딩 게이트장치에 있어서,상노즐(110)과 하노즐(120) 사이에서 직선이동되는 한쌍의 중간 플레이트(10a)(10b);상기 한쌍의 중간 플레이트(10a)(10b)를 전,후진 구동하는 실린더(15);상기 중간 플레이트(10a)(10b)내에서 회전되고, 중앙에는 각각 타원형 구멍(h1)(h2)들이 형성되는 한쌍의 회전판(20a)(20b); 및상기 실린더(15)의 반대측으로 형성된 상기 회전판(20a)(20b)의 호형 치차부(25a)(25b)에 기어(33a)(33b)들이 각각 치차결합하여 상기 회전판(20a)(20b)의 회전각도가 변위되도록 회전시킴으로써 상기 구멍(h1)(h2)들의 개도율을 조절하는 회전모터(30a)(30b);를 포함하고,상기 회전판(20a)(20b)은 상기 회전모터(30a)(30b)에 의해서 회전되어 상기 타원형 구멍(h1)(h2)들이 서로 교차하면 그 연통되는 부분이 최소가 되어 최소 회전 개도를 나타내고, 상기 회전판(20a)(20b)의 타원형 구멍(h1)(h2)들이 서로 일치하면 개도율이 최대로 되어 최대 회전개도를 유지함을 특징으로 하는 연속주조용 슬라이딩 게이트장치.
- 제 1항에 있어서, 상기 회전판(20a)(20b)은 각각 상기 중간 플레이트(10a)(10b)의 중앙에 마련된 끼움구멍(12a)(12b)으로 삽입되는 원형 단턱(22a)(22b)을 갖추고, 상기 중간 플레이트(10a)(10b)에 회전가능하도록 결합되는 것임을 특징으로 하는 연속주조용 슬라이딩 게이트장치.
