Description
Claims (3)
- 노즐(1)로부터 공급된 용강(2)을 냉각수가 흐르는 한쌍의 롤(3a)(3b)사이로 주입하여 주편(5)을 제조하는 박판주조기에 있어서,상기 롤(3a)(3b)의 중앙부(7)에 크라운(C)의 밑면길이(23)와 동일한 밑변길이(24)로 이루어지고, 상기 크라운(C)의 반경방향 높이(22)보다 2배의 높이(15)로 이루어져 상기 크라운(C)의 기울기에 비하여 2배의 기울기로 이루어지는 복수개의 굴곡부(20)를 형성하여 상기 롤(3a)(3b)의 폭방향으로의 응고능을 균일하게 함을 특징으로 하는 쌍롤형 박판주조기용 냉각롤.
- 제 1항에 있어서, 상기 크라운(C)의 밑면길이(23)가 50 내지 100mm의 길이로 형성됨을 특징으로 하는 쌍롤형 박판주조기용 냉각롤.
- 제 1항에 있어서, 상기 굴곡부(20)는 이와 접해지는 주편(5)의 상,하부면에서의 응고능의 차이를 상쇄시킬수 있도록 상기 굴곡부(20)에 의해서 양 롤(3a)(3b)의 외주면에 형성되는 요철부분이 서로 상쇄되도록 형성됨을 특징으로 하는 쌍롤형 박판주조기용 냉각롤.
