Abstract
Description
Claims (3)
- 미니밀 공정 중 연속주조에서 제조되는 슬라브에 생성되는 스케일을 제거하기 위한 장치에 있어서,상기 슬라브의 상부 및 하부에 위치되는 상부베이스 및 하부베이스;상기 상부베이스 및 하부베이스에 설치되어 고압의 공기가 이동하는 매니폴드;상기 매니폴드에 설치되어 상기 슬라브의 상하 표면에 상기 고압의 공기를 음속으로 분사하는 초음속 분사노즐;상기 초음속 분사노즐이 상하로 이동하기 위한 조절실린더; 및상기 상부베이스 및 하부베이스에 각각 설치되어 상기 슬라브를 이동시키는 구동롤를 포함하되,상기 초음속 분사노즐은 상기 고압의 공기의 분사되는 압력의 크기에 따라 상하로 승강하는 것을 특징으로 하는 스케일 제거장치.
- 제 1 항에 있어서,상기 초음속 분사노즐은 코안다 효과(coanda effect)에 의해 주변의 공기를 흡입하도록 내부에 오리피스곡면(orifice surface)이 형성되는 것을 특징으로 하는 스케일 제거장치.
- 제 1 항에 있어서,상기 초음속 분사노즐은 상기 슬라브가 삽입되는 방향을 향하여 경사진 것을 특징으로 하는 스케일 제거장치.
