以相似原理为基础,通过建立1∶4的水模型对单流板坯连铸中间包进行模拟研究。研究了在不同的流量下挡墙挡坝位置以及挡坝高度对中间包流场的影响,得出了最佳内腔的控流装置组合。研究表明,最佳控流装置组合的挡墙和长水口距离为390 mm,挡墙和挡坝距离130 mm,挡坝高度为135 mm的效果较佳。在流量分别为1.01 m~3/h和1.26 m~3/h时,最短响应时间分别增加了25.8 s、30.6 s,中间包钢液实际停留时间延长了64.07 s、58.93 s,死区体积分别减小了14.62%、16.77%。
Based on the similar principle, a 1: 4 water model was used to simulate the single-flow slab continuous casting tundish. The influence of retaining wall retaining dam position and dam height on the flow field of tundish at different flow rates was studied, and the optimal flow control device combination of cavities was obtained. The study shows that the best flow control device combination of the retaining wall and the shroud distance of 390 mm, retaining wall and retaining dam distance 130 mm, retaining dam height of 135 mm better. The shortest response time increased by 25.8 s and 30.6 s respectively when the flow rate was 1.01 m ~ 3 / h and 1.26 m ~ 3 / h, respectively, and the actual residence time of the molten steel in the tundish extended by 64.07 s and 58.93 s respectively. A decrease of 14.62% and 16.77%.
