- 슬라이딩 게이트로 턴디시에서 주형으로 공급되는 용강의 유량을 제어하는 방식의 연속주조 방법에 있어서,주조개시 초기에 턴디시 노즐을 슬라이딩 게이트로 밀폐한 상태에서 상기 턴디시의 상부노즐 내부 형상을 중심축에 대하여 경사진 형태가 되도록 함과 동시에, 노즐내 회전와류를 형성할 수 있도록 슬라이딩 게이트의 상부 플레이트에 노즐 반지름방향과 어긋나도록 다수의 가스분사관을 설치하여 불활성가스를 분사하도록 하여 용강환류를 촉진하고 개재물에 의한 노즐막힘을 방지하도록 하는 것을 특징으로 하는 슬라이딩 게이트 제어방식의 턴디시에서의 연속주조 방법.
- 제 1항에 있어서,상기 상부노즐의 벽면에 다공질을 형성하여 가스취입을 하고, 상기 상부 플레이트의 분사관을 통한 가스취입을 동시에 하며 상기 불활성 가스인 아르곤의 유량은 40∼120 l/min이 되도록 하는 것을 특징으로 하는 슬라이딩 게이트 제어방식의 턴디시에서의 연속 주조방법.
