Abstract

본 발명은 쌍롤 또는 단롤 방식에 의한 강(綱)의 박판주조시 사용되는 롤표면에 100메쉬(Mesh) 이하로 조도(거침)를 설정하여 줌으로써, 용강과 롤간의 접촉표면적 증대에 의하여, 용강으로부터 롤쪽으로의 열전달 효율 즉, 냉각효율을 높히고 균일한 열전달에 의한 균일냉각을 가능케 하는 것을 특징으로 하는 주조 박강판의 표면 및 내부품질 향상 방법이다.According to the present invention, roughness is set to 100 mesh or less on the roll surface used for thin sheet casting of a single roll or single roll method, and thus the molten steel and the roll increase the contact surface area. It is a method for improving the surface and internal quality of a cast steel sheet characterized by increasing heat transfer efficiency to the roll, that is, cooling efficiency and enabling uniform cooling by uniform heat transfer.
