摘　　要：采用物理模拟的方法,研究拉速0.8m/min、1.0m/min、1.2m/min,长水口插入深度200mm、300mm对中间包内钢液的停留时间分布曲线和流场的影响,结果表明0.8m/min和1.0m/min拉速下,停留时间分布曲线存在着明显的双峰现象,而1.2m/min拉速下曲线的双峰现象不明显。0.8m/min拉速下,中间包内存在着明显的死区。实验中间包的最优冶金工艺为:长水口插入深度300mm,拉速1.2m/min。The effects of casting speed of 0.8 m/min, 1.0 m/min, 1.2 m/min, ladle shroud insertion depth of 200 mm and 300 mm on the residence time distribution curve and flow field of molten steel in tundish are studied by means of physical simulation. The results show that there are obvious double peaks in the residence time distribution curve at 0.8 m/min and 1.0 m/min casting speed, while the double peaks in the 1.2 m/min casting speed curve are not obvious. At the casting speed of 0.8 m/min, there are obvious dead zones in the tundish. The optimum metallurgical process of the tundish is as follows: the insertion depth of the ladle shroud is 300 mm, and the casting speed is 1.2 m/min.
