Claims (3)
- 쌍롤식 박판주조공정에서 상부 토출구와 하부 측방토출구 및 하부 하향토출구를 갖는 광폭침지노즐(N)로부터 수냉되고 있는 한쌍의 주조롤에 용강을 공급하면서 주편을 제조함에 있어서, 주조초기에는 용강토출을 방지하고, 용강이 상기 침지노즐(N)의 상부 토출구에서 토출될 때 용융되면서 용강을 토출할 수 있도록 구성되며, 주조 대상금속과 동일하거나 유사한 조성을 갖는 용강 토출지연판을 상기 침지노즐(N)의 하부 측방토출구와 하부 하향토출구에 형성함으로써 주조중 안정적으로 용강을 공급할 수 있는 쌍롤식 박판 주조기용 침지노즐의 용강공급 제어방법.
- 삭제
- 제1항에 있어서, 상기 용강 토출지연판은 그 두께가 2~ 5 mm 정도임을 특징으로 하는 하는 쌍롤식 박판 주조기용 침지노즐의 용강공급 제어방법.
