Computer Modelling of Molten Metal Flowfields in Continuously Casting Strip(Ⅱ) = 연속주편에서 용융금속유동장의 컴퓨터모델링(Ⅱ)

국문 초록 (Abstract)

상롤박판주조기내 SUS 304 용융금속의 주조과정을 설명하는 컴퓨터 모델이 개발되었으며, 그 지배방정식들은 곡선 좌표계로 변환하여 사용하였고, 그 계산 과정이 주어져 있다. 계산결과로는 쌍률사이의 유동장내 중앙부 근방에서 재회전류가 존재함을 알 수 있었으며 또한, 침지도는 깊이 변화에 따라 좁은 영역의 회전류가 나타남을 볼 수 있다.

다국어 초록 (Multilingual Abstract)

A computer model has been developed for describing the flowfields of molten steel (SUS 304) in the twin-roll strip casting process with solidification pattern. The governing equations were transformed to a curvilinear coordinate system and an outline of the computational approach was also given. It was found that the flowfields with recirculating flow are located in the vicinity of the middle of the rotating bank of molten steel. The small cavity zone with fixed parameter appears with increasing nozzle depth.
