摘　　要：运用Fluent 6.3软件对中间包进行数值计算,研究了控流装置等因素对中间包温度场的影响。结果表明:中间包内控流装置结构越简单,入口和出口之间温差越小,整个中间包的温度场分布更加均匀。为减小注流区中间包熔池深度方向上的温度变化梯度,应增加中间包内挡墙与长水口之间的距离;为提高中间包内温度场的均匀性,应适当增加中间包长水口浸入深度,控制中间包的熔池深度,本试验中间包熔池深度应控制在1 200 mm左右,模拟结果在现场得到了有效验证。A tundish was numerically calculated by software Fluent 6.3, and the effect of the flow control devices and other factors on the tundish temperature field was studied. The results showed that the easier the flow control devices in tundish, the less temperature difference between the entrance and the exit in tundish, and the better distribution of temperature field of the whole tundish. In order to decrease the temperature gradient variation in molten pool depth direction of pouring region in the tundish, the distance between baffles and long nozzle in the tundish should be as long as possible. As to increase the homogenization of temperature field of tundish, the immersion depth of long nozzle should increase properly, and the pool depth of tundish should be proper. In this study, the proper pool depth of tundish is 1 200 mm approximately. The simulated result was proved in production line.
