采用水模型模拟的方法，对某钢厂十机十流连铸机中间包中的一个完全不对称结构的五流L型中间包进行流场优化。试验结果表明：控流最优方案为湍流抑制器T+副导流墙D2+上2孔倾角为25°下靠近后墙单孔倾角30°的3孔主导流墙D1a。采用该方案可使染色剂到达各出口的时间增加，各流响应时间差减小，RTD峰值浓度减小以及高浓度存在的时间延长，各流之间的死区比例减小。
In this paper, the water model method is used to optimize the flow behavior of asymmetrical five streams L-type tundish in a steelmaking plant. The results show that the optimization plan is set up with turbulence suppressor T+ vice guide wall D2+ main guide wall with three holes (D1a) which consists of top two holes with 25° inclination and one hole with 30° inclination below. With this plan, the time which the colorants reach to the outlets increases, the difference of response time in all outlets decreases, the peak concentration of the RTD reduces, the existence time of high concentration liquid steel extends, and the ratio of dead zone in each streams reduces.
