Claims (3)
- 노즐로 부터 공급된 용강을 한쌍의 주조롤 사이로 통과시켜 박판을 주조하는 쌍롤식 박판주조기의 주조롤 표면에 딤플을 형성하는 표면처리방법에 있어서,상기 주조롤의 표면에 30∼60°의 투사각도(α)로 쇼트볼을 투사하여 편심된 반구형의 딤플(31)을 다수개 형성하는 것을 포함하여 이루어지는 쌍롤식 박판주조기 주조롤의 표면처리방법.
- 제 1항에 있어서, 상기 쇼트볼의 직경은 0.5∼3mm임을 특징으로 하는 쌍롤식 박판주조기 주조롤의 표면처리방법.
- 제 1 또는 제 2항에 있어서, 상기 쇼트볼의 투사압력은 5-15바(bar)임을 특징으로 하는 쌍롤식 박판주조기 주조롤의 표면처리방법.
