Claims (3)
- 양변에 다수개의 토출구가 뚫려있는 침지노즐을 매개로 하여 서로 반대 방향으로 회전하는 쌍롤과 에지댐으로 한정되는 용강풀 내로 용강을 공급하여 박판을 연속주조하는 장치에 있어서, 상기 침지노즐의 토출구의 각도가 수평면으로부터 상향각인 것을 특징으로 하는 쌍롤식 연속박판주조장치용 침지노즐.
- 청구항 1에 있어서,상기 침지노즐의 토출구의 각도는 수평면으로부터 5°~20° 상향인 것을 특징으로 하는 쌍롤식 연속박판주조장치용 침지노즐.
- 청구항 1 또는 2에 있어서,상기 침지노즐의 다수개의 토출구가 침지노즐 폭 중앙에 위치한 토출구로부터 에지댐 측에 위치한 토출구로 갈수록 상기 토출구의 각도가 점점 작게 되는 것을 특징으로 하는 쌍롤식 연속박판주조장치용 침지노즐.
