연속주조 턴디쉬 내 유동제어부재의배열 변경에 따른 용강유동 거동의 수모델 실험

초록

The tundish is necessary to separate impurities (slag) from the molten steel and to keep the steel to be cast pure in continuous casting(CC) process. The tundish also serves as a storage vessel for the molten steel during a ladle change in order not interrupt the casting process. Therefore, understanding of the arrangement of the flow control devices (i.e. baffles, dams, weirs and so on) and thus its effect to the flow pattern of the molten steel within the tundish is basic and essential parts of accomplishing the highest cleanliness of the steel. In this study, a 1/3 reduced tundish water model with four arrangements of flow control devices within the tundish was used to simulate and compare the characteristics of corresponding molten steel flow behaviors in prototype.
